Abuse and Neglect in Childhood: Relationship to Personality Disorder Diagnoses
Authors: Bierer Linda M. , Yehuda Rachel , Schmeidler James , Mitropoulou Vivian , New Antonia S. , Silverman Jeremy M. , Siever Larry J.
Published: August 2016

Background:

Childhood history of abuse and neglect has been associated with personality disorders and has been observed in subjects with lifetime histories of suicidality and self-injury. Most of these findings have been generated from inpatient clinical samples.

Methods:

This study evaluated self-rated indices of sustained childhood abuse and neglect in an outpatient sample of well-characterized personality disorder subjects (n=182) to determine the relative associations of childhood trauma indices to specific personality disorder diagnoses or clusters and to lifetime history of suicide attempts or gestures. Subjects met criteria for ~2.5 Axis II diagnoses and 24% reported past suicide attempts. The Childhood Trauma Questionnaire was administered to assess five dimensions of childhood trauma exposure (emotional, physical, and sexual abuse, and emotional and physical neglect). Logistic regression was employed to evaluate salient predictors among the trauma measures for each cluster, personality disorder, and history of attempted suicide and self-harm. All analyses controlled for gender distribution.

Results:

Seventy-eight percent of subjects met dichotomous criteria for some form of childhood trauma; a majority reported emotional abuse and neglect. The dichotomized criterion for global trauma severity was predictive of cluster B, borderline, and antisocial personality disorder diagnoses. Trauma scores were positively associated with cluster A, negatively with cluster C, but were not significantly associated with cluster B diagnoses. Among the specific diagnoses comprising cluster A, paranoid disorder alone was predicted by sexual, physical, and emotional abuse. Within cluster B, only antisocial personality disorder showed significant associations with trauma scores, with specific prediction by sexual and physical abuse. For borderline personality disorder, there were gender interactions for individual predictors, with emotional abuse being the only significant trauma predictor, and only in men. History of suicide gestures was associated with emotional abuse in the entire sample and in women only; self-mutilatory behavior was associated with emotional abuse in men.

Conclusion:

These results suggest that childhood emotional abuse and neglect are broadly represented among personality disorders, and associated with indices of clinical severity among patients with borderline personality disorder. Childhood sexual and physical abuse are highlighted as predictors of both paranoid and antisocial personality disorders. These results help qualify prior observations of the association of childhood sexual abuse with borderline personality disorder.
Psychosocial Approaches of Acute Stress Reactions
Authors: Bryant Richard A.
Published: August 2016

What are the conceptual and empirical bases for current interventions for acute stress reactions following trauma exposure? This review compares the two major alternatives to managing acute stress reactions, outlines their conceptual bases and critiques the evidence for their efficacy in preventing subsequent stress disorders. The review integrates current evidence for cognitive behavior therapy with recent neuroscience findings that fear reduction learning can be enhanced by modulating glutamaterigc systems. D-cycloserine provides exciting opportunities to enhance the effects of cognitive-behavioral therapy, and points to closer understanding of the biological mechanisms that underpin clinical gains achieved by psychological therapies.
Is SAD Lost to SAD?
Authors: Kasper Siegfried
Published: August 2016

Since 1984, 447 articles have been published using the acronym “SAD” for seasonal affective disorder in the heading of the publication, and since 1992, 59 articles have used “SAD” in the heading of the publication as an acronym for social anxiety disorder, according to MEDLINE. Using the acronym SAD for social anxiety disorder has been used with more frequency in recent scientific publications—interestingly, mostly in connection with newer antidepressants that have been found to be of therapeutic potential for this indication. To avoid possible confusions in research, the acronym “SOAD” was proposed for social anxiety disorder by Kasper and Winkler and “SAnD” by Nutt (D.J. Nutt, MD, PhD, unpublished data, 2004)—seemingly without success since these abbreviations are not seen in the literature. This month, CNS Spectrums focuses on the existing literature on the original acronym for SAD—seasonal affective disorder and its worldwide recognition.

In the early 1980s, Rosenthal and colleagues at the National Institute of Mental Health (NIMH) set out to describe a syndrome called SAD, not to be confused with the other, more recent SAD, social anxiety disorder. The original has been known to physicians since ancient times, dating back to Aretaeus the Cappadocian. However, the NIMH researchers for the first time systematically described the clinical symptomatology, compared it with healthy controls, and differentiated SAD from nonseasonal depression. Their work in tandem with emerging technology led to the discovery of the underlying pathophysiology of SAD and treatment approaches. The most important of these approaches were light therapy and pharmacotherapeutic options.
Treatment-Refractory Schizoaffective Disorder in a Patient with Dyke-Davidoff-Masson Syndrome
Authors: Amann Benedikt , de la Iglesia Celia García , McKenna Peter , Pomarol-Clotet Edith , Sanchez-Guerra Marisa , Orth Michael
Published: August 2016

Dyke-Davidoff-Masson syndrome, or cerebral hemiatrophy, is a pre- or perinatally acquired entity characterized by predominantly neurologic symptoms, such as seizures, facial asymmetry, contralateral hemiplegia, and mental retardation. Psychiatric symptoms are rarely reported. We report the first case of left cerebral hemiatrophy and a late onset of treatment-resistant schizoaffective disorder after a stressful life event. The patient finally responded well to clozapine. The clinical history and results from structural neuroimaging are highlighted to discuss the possible developmental bias for psychotic disorders.
Disordered Gambling Among Racial and Ethnic Groups in the US: Results From the National Epidemiologic Survey on Alcohol and Related Conditions
Authors: Alegría Analucía A. , Petry Nancy M. , Hasin Deborah S. , Liu Shang-Min , Grant Bridget F. , Blanco Carlos
Published: August 2016

Introduction: Prior research suggests that racial minority groups in the United States are more vulnerable to develop a gambling disorder than whites. However, no national survey on gambling disorders exists that has focused on ethnic differences.

Methods: Analyses of this study were based on the National Epidemiologic Survey on Alcohol and Related Conditions, a large (N=43,093) nationally representative survey of the adult (≥18 years of age) population residing in house-holds during 2001–2002 period. Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision diagnoses of pathological gambling, mood, anxiety, drug use, and personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IVVersion.

Results: Prevalence rates of disordered gambling among blacks (2.2%) and Native/Asian Americans (2.3%) were higher than that of whites (1.2%). Demographic characteristics and psychiatric comorbidity differed among Hispanic, black, and white disordered gamblers. However, all racial and ethnic groups evidenced similarities with respect to symptom patterns, time course, and treatment seeking for pathological gambling.

Conclusion: The prevalence of disordered gambling, but not its onset or course of symptoms, varies by racial and ethnic group. These varying prevalence rates may reflect, at least in part, cultural differences in gambling and its acceptability and accessibility. These data may inform the need for targeted prevention strategies for high-risk racial and ethnic groups.
Suicidal Ideation in Parkinson's Disease
Authors: Kummer Arthur , Cardoso Francisco , Teixeira Antonio Lucio
Published: August 2016

Objective: To assess the frequency of suicidal ideation and suicide attempts in patients with Parkinson's disease.

Methods: The Mini International Neuropsychiatric Interview (MINI), Beck Depression Inventory (BDI), and Hamilton Rating Scale for Depression (HAM-D) were administered to 90 consecutive, non-demented Parkinson's disease patients. They were also submitted to a complete neurologic examination which included brief cognitive batteries, the Mini Mental Status Exam, and Frontal Assessment Battery. We analyzed the scores of the section of the MINI related to the risk of suicide as well as the specific questions of BDI and HAM-D concerning suicidal ideation.

Results: No patient had ever attempted suicide. According to MINI, suicidal ideation was present in 13 patients (14.4%) with Parkinson's disease. All instruments assessed the risk of suicide in a similar way. Suicidal ideation was associated only with lower age (P=.022), lower age of Parkinson's disease onset (P=.021), panic disorder (P=.004), social anxiety disorder (P=.007), and major depression (P<.001). Logistic regression analysis indicated that major depression was the main predictor of suicidal ideation.

Conclusion: Suicide attempts seem to be uncommon in Parkinson's disease, despite the fact that the rates of suicidal ideation are possibly elevated. Depression seems to be the most important predictor of suicidal ideation in Parkinson's disease.
The Switching of Risperidone to Olanzapine in Elderly Nursing-Home Patients with Dementia: A Retrospective Study
Authors: Madhusoodanan Subramoniam , Bogunovic Olivera
Published: August 2016

Background:

The behavioral and psychological symptoms of dementia present a major challenge in the management of these patients. There is no Food and Drug Administration-indicated medication for the management of these symptoms. Even though atypical antipsychotics are considered safer than conventional antipsychotics, safety concerns have emerged.

Introduction:

The FDA has issued warnings regarding the cardiac and metabolic side effects, cerebrovascular events, and, most recently, mortality risk. This study was conducted in 2003 when physicians were notified of the cerebrovascular risks of risperidone. Since then, similar warnings have been issued for olanzapine and aripiprazole.

Methods:

The medical records of 58 elderly dementia patients who were taking risperidone and were abruptly switched to olanzapine were reviewed. Clinical Global Impressions scale at assigned retrospectively at switch, and weeks 4–6 assessed treatment.

Results:

Baseline and follow-up Clinical Global Impressions scale scores were essentially unchanged. Adverse events were mild to moderate in severity. Mean risperidone dose at switch was 1.54 mg/day (range: 0.25–6 mg/day). Mean olanzapine dose after the switch was 5.69 mg/day (range: 2.52–27.5 mg/day).

Conclusion:

Most of the 58 patients were switched from risperidone to olanzapine without any deterioration in their clinical status. Even though it is generally not recommended in elderly patients, abrupt switching did not have any negative consequences in this group of patients.
Mitochondrial Myopathy Complicated by Eating Disorder: A Case Report Highlighting the Potential Interaction of Genetic, Metabolic, and Psychodynamic Factors
Authors: Deutsch Stephen I. , Rosse Richard B. , Yaseen Mohammad , Schulman Howard M. , Abraham Samathanam
Published: August 2016

A case is presented of a 56-year-old woman with a history of an eating disorder that preceded recognition of a mitochondrial myopathy.The possibility exists that her eating disorder was causally related to a more fundamental defect in mitochondrial oxidative metabolism. This case report highlights the phenotypic variability of mitochondrial myopathies. An increased risk of eating disorder may be associated with drugs that interfere with mitochondrial oxidative respiration.
The Relationship of Body Dysmorphic Disorder and Eating Disorders to Obsessive-Compulsive Disorder
Authors: Phillips Katharine A. , Kaye Walter H.
Published: August 2016

Body dysmorphic disorder (BDD) and eating disorders are body image disorders that have long been hypothesized to be related to obsessive-compulsive disorder (OCD). Available data suggest that BDD and eating disorders are often comorbid with OCD. Data from a variety of domains suggest that both BDD and eating disorders have many similarities with OCD and seem related to OCD. However, these disorders also differ from OCD in some ways. Additional research is needed on the relationship of BDD and eating disorders to OCD, including studies that directly compare them to OCD in a variety of domains, including phenomenology, family history, neurobiology, and etiology.
Brain Hemispheric Organization, Anxiety, and Psychoses
Authors: Galderisi Silvana , Mucci Armida , Maj Mario
Published: August 2016

Abnormalities of brain hemispheric organization have been found in a variety of psychiatric disorders. Despite the great amount of data collected and the number of theoretical models elaborated, the role of these abnormalities in the pathogenesis of these disorders remains controversial. This article briefly reviews current concepts of hemispheric functioning, discusses the role of abnormalities of brain hemispheric organization in schizophrenia and in two anxiety disorders (panic disorder and obsessive-compulsive disorder), and outlines a developmental perspective that accounts for the observed abnormalities.
Brain-Immune Interactions in Neuropsychiatry: Highlights of the Basic Science and Relevance to Pathogenic Factors and Epiphenomena
Authors: Petitto John M. , Repetto Martin J. , Hartemink David A.
Published: August 2016

Unraveling the significant complexity of brain-immune interactions could provide essential new insights and potential treatment considerations for the clinical neurosciences. Despite considerable research relating immunological changes to major neuropsychiatric disorders, it has been difficult to establish that immunological processes are involved in the development of central nervous system pathology associated with these disorders. This brief article highlights some of the landmark basic studies and seeks to convey essential principles guiding research in brain-immune interactions. Research in this area often incorporates several disciplines, ranging from psychology and neuroscience to immunology and molecular genetics. The clinical implications of this area of research are discussed, with emphasis on the challenge of disentangling pathogenic factors and valid markers of disease from epiphenomena.
Electrical Stimulation of the Brain for Psychiatric Disorders
Authors: Nuttin Bart , Gabriëls Loes , Cosyns Paul , Gybels Jan
Published: August 2016

Despite advances in therapies, there remain psychiatric patients who are extremely ill and cannot be helped by classic psychiatric treatments, including psychotherapy and drug therapy. Certain of these patients may be helped by use of bilateral brain lesioning. The complication rate of standard stereotactic psychosurgery techniques is very low. The main rationale for the continued experimental use of deep brain stimulation (DBS) in neurosurgery for mental disorders is its reversibility. This reversibility is not an advantage in terms of the benefits obtained, but rather if side effects emerge. In addition, electrical stimulation may provide patients with some autonomy for their treatment. The first, very preliminary results of electrical stimulation for obsessive-compulsive disorder and for a small heterogeneous group of patients with other psychiatric disorders have been published. Electrical stimulation of the brain for psychiatric disorders may become a new treatment option for certain intractable psychiatric disorders. Nevertheless, the mechanism of action of DBS in psychiatric disorders is unknown, and the experience with this modality is extremely limited. The first results look promising, but this treatment option may prove unusable for some time because of a lack of knowledge of appropriate brain stimulation targets and technical problems such as the availability of sufficient current supply.
Cognitive Deficits Following Coronary Artery Bypass Grafting: Prevalence, Prognosis, and Therapeutic Strategies
Authors: Raja Pushpa V. , Blumenthal James A. , Doraiswamy P. Murali
Published: August 2016

There is increasing recognition that coronory artery bypass grafting (CABG) may be a risk factor for subtle cognitive decline although the presence and pattern of such decline has varied across studies. Cognitive deficits may present as short-term memory loss, executive dysfunction and psychomotor slowing. Although they are usually are not severe enough to meet criteria for mild cognitive impairment or vascular dementia, they lower quality of life and add to hospitalization and out-of-hospital costs. Proposed mechanisms include surgical-related trauma, genetic susceptibility (eg, apolipoprotein E4 allele), microembolization, other vascular or ischemic changes, and temperature during surgery. Depression and anxiety levels predict subjective perception of these deficits more than objective cognitive performance. Both nonpharmacologic (eg, emboli reduction, temperature, or glucose management) and pharmacologic (eg, dexanabinol, glypromate, nootropics) strategies to prevent post-CABG cognitive deficits are under investigation. Given the large numbers of subjects who may already have CABG associated cognitive deficits, clinical trials of agents being tested for Alzheimer's disease (eg, donepezil, rivastigmine, memantine, neramexane, ginkgo) may also be informative. The results of multicenter long-term outcome studies (with matched control groups) as well as ongoing treatment trials will more conclusively address some of these issues. These data emphasize the need for clinicians to monitor cognitive function before and after coronary bypass surgery, and to educate patients.
Perimenopausal Mental Disorders: Epidemiology and Phenomenology
Authors: Rasgon Natalie , Shelton Stephanie , Halbreich Uriel
Published: August 2016

Perimenopause, the interval of irregular menstrual activity which directly precedes menopause, is characterized by widely fluctuating hormone levels amidst a large-scale decline in circulating estrogen. This phase in a woman's life is typically accompanied by physical discomforts including vasomotor symptoms, such as headaches, insomnia, and hot flushes, as well as genital atrophy. Not surprisingly, studies suggest a significant increase in mood lability for women during this time. While some evidence points toward an exacerbation of bipolar mood symptoms and an increase in schizophrenic psychosis during perimenopause, the majority of research conducted on perimenopausal mental disorders has focused on unipolar depression. Studies vary widely in methodology, definitions of menopausal status, and degrees of depression among subjects; however, the majority of findings indicate an increased susceptibility to depression during the perimenopausal transition. This greater susceptibility may be due to neuroendocrine effects of declining estrogen levels, the subjective experience of somatic symptoms resulting from this hormonal decline, and/or the more frequent occurrence of “exit” or “loss” events for women during this stage of life. At this time, more research is needed to address questions of prevalence, risk, and etiology for depression and other major mental disorders as related to the physiological and psychosocial changes associated with perimenopause.
Suicide: Risk, Impact, and Prevention
Authors: Goodwin Frederick K. , Ghaemi S. Nassir , Hollander Eric
Published: August 2016

The power of the life force is striking—in even among the most abominable conditions, like concentration camps, suicide remains relatively uncommon. Yet some human beings appear to harbor a powerful destructive force, which can under certain conditions manifest itself in violence, homicide, or suicide. Suicide has been with us since the beginning of history; it has often been romanticized, or viewed as an understandable escape from an intolerable situation. Philosophers and writers from William James to Albert Camus to Goethe have tended to view suicide as a window into the human condition, perhaps extreme but nevertheless a reflection of our shared humanity. However, highly reliable research has shown that suicide is, by and large, not a window into the human condition, but rather a manifestation of a disturbance—an abnormality of the human condition—a mental disorder.

Physicians know that the primary goal of medical treatment (after first doing no harm) is to prevent death. Death is the ultimate enemy in medical illness. In psychiatric illness, this enemy usually appears in the guise of suicide; the illness uses the hands of patients to wreak its havoc. To reduce mortality in psychiatric conditions, then, means to reduce suicide. It is indeed striking how little this matter has been analyzed. Little data are available on mortality with medications that are researched and approved for psychiatric illness. This would not be acceptable for medical illnesses outside of psychiatry today; it should not be the case in psychiatric illnesses either.
Depression and HIV Infection: Impact on Immune Function and Disease Progression

Published: August 2016

Can psychological factors, such as depression, affect human immunodeficiency virus progession? HIV infection is viewed as a chronic illness in which those infected often confront a number of emotional challenges and physical health and disease-related issues. Over the past 20 years, there has been increasing evidence that depression and other mood-related disturbances are commonly observed among HIV-positive individuals. There is also mounting data showing that depressive symptoms might further impact upon specific elements of immune system functioning and influence quality of life and health status. This paper will highlight studies examining the prevalence of depression during HIV infection and review some of the evidence examining the impact of depressive symptoms on immune function and HIV disease progression.
FDA Considers Classification of ECT
Authors: Lisanby S.H. , Pallanti Stefano , Schlaepfer Thomas E.
Published: August 2016

With the increasing number of new brain stimulation techniques now available and on the horizon, does electroconvulsive therapy (ECT) still have a role? As clinicians and researchers we say most definitely “yes”. ECT is the most effective and rapidly acting treatment for severe forms of depression and other disorders. Transcranial magnetic stimulation has shown promise but mainly for less severely ill and less treatment resistant patients. Deep brain stimulation (DBS) has shown promise for the more resistant cases but its invasiveness limits its use. Results from only ∼50 patients treated worldwide are available and at present it is not approved by the United States Food and Drug Administration for depression. Vagus nerve stimulation, less invasive than DBS but still a surgical procedure, is presently FDA approved for acute treatment resistant depression but published efficacy rates fall short of those seen with ECT. Therefore, there continues to be an important role for ECT in the treatment of severe psychiatric disorders. But will ECT always be there when our patients need it? Somewhat unexpected recent developments at the FDA may impact the future availability of ECT to severely depressed patients. Here we provide background on the classification of ECT devices, the FDA reclassification process, and the process for providing FDA input in these critical deliberations.
Crisis in Army Psychopharmacology and Mental Health Care at Fort Hood
Authors: Stahl Stephen M.
Published: August 2016

The recent shootings at Ft. Hood, allegedly by an army psychiatrist, have placed much needed focus on army mental health care. Questions are now being raised as to whether longstanding and severe shortages in the number of mental health professionals in the army may have led authorities to overlook danger signals in this psychiatrist, failing to remove him in order to retain a worker with rare and valuable psychiatric credentials for army service. Whether or not this is the case, examination of mental health care in the army shows a system that is indeed understaffed, under tremendous pressure, and near the breaking point.
An fMRI Study Examining Effects of Acute D-Cycloserine During Symptom Provocation in Spider Phobia
Authors: Aupperle Robin L. , Hale Lisa R. , Chambers Rebecca J. , Cain Sharon E. , Barth Frank X. , Sharp Susan C. , Denney Douglas R. , Savage Cary R.
Published: August 2016

Background: Exposure-based therapy for anxiety disorders is believed to operate on the basis of fear extinction. Studies have shown acute administration of D-cycloserine (DCS) enhances fear extinction in animals and facilitates exposure therapy in humans, but the neural mechanisms are not completely understood. To date, no study has examined neural effects of acute DCS in anxiety-disordered populations.

Methods: Two hours prior to functional magnetic resonance imaging scanning, 23 spider-phobic and 23 non-phobic participants were randomized to receive DCS 100 mg or placebo. During scanning, participants viewed spider, butterfly, and Gaussian-blurred baseline images in a block-design paradigm. Diagnostic and treatment groups were compared regarding differential activations to spider versus butterfly stimuli.

Results: In the phobic group, DCS enhanced prefrontal (PFC), dorsal anterior cingulate (ACC), and insula activations. For controls, DCS enhanced ventral ACC and caudate activations. There was a positive correlation between lateral PFC and amygdala activation for the placebo-phobic group. Reported distress during symptom provocation was correlated with amygdala activation in the placebo-phobic group and orbitofrontal cortex activation in the DCS-phobic group.

Conclusions: Results suggest that during initial phobic symptom provocation DCS enhances activation in regions involved in cognitive control and interoceptive integration, including the PFC, ACC, and insular cortices for phobic participants.
Selective Phosphodiesterase Type-5 Inhibitor Treatment of Serotonergic Reuptake Inhibitor Antidepressant-Associated Sexual Dysfunction: A Review of Diagnosis, Treatment, and Relevance
Authors: Nurnberg H. George , Hensley Paula L.
Published: August 2016

Sexual dysfunction related to antidepressants, particularly serotonin reuptake inhibitors is a major cause of premature treatment discontinuation. This places patients at increased risk for recurrence, relapse, chronicity, and mortality (eg, suicide). The clinical assessment requires a comprehensive evaluation of sexual function, including libido, arousal, orgasm, and resolution prior to affective disorder, disturbances associated with the emergence of depression, and changes or dysfunctions associated with antidepressant treatment. Other factors to be included for evaluating sexual dysfunction include inquiry for concurrent medical conditions, somatic treatments, lifestyle risk factors, and response to antidepressants. Current treatment approaches to antidepressant-associated sexual dysfunction have relied on open-label reports, literature reviews, and clinical wisdom. Without double-blind, placebo-controlled studies to support them, too much non-evidence-based treatment may be offered to patients. Advances into nonadrenergic-noncholinergic novel signal transduction, specifically phosphodiesterase type-5 inhibitors, offer new opportunities for developing evidence-based treatments for this side effect and improving depression disease management outcomes.
What Is the Rationale for New Treatment Strategies in Alzheimer's Disease?
Authors: Rogawski Michael A.
Published: August 2016

Alzheimer's disease (AD) is characterized by the abnormal extracellular accumulation of amyloid β-peptide (Aβ) into neuritic plaques and the intraneuronal aggregation of the microtubule-associated protein tau to form neurofibrillary tangles. These molecular events are implicated in the selective damage to neural systems critical for the brain functions that are impaired in AD. Impairment of cholinergic neurotransmission may be an important factor underlying the defects in cognition and memory that characterize AD. Cholinesterase (ChE) inhibitors, such as donepezil, rivastigmine, and galantamine, cause symptomatic improvement by inhibiting the breakdown of the neurotransmitter acetylcholine to increase its synaptic availability and, in the case of galantamine, by also allosterically potentiating nicotinic cholinergic receptors. Other agents, including vitamin E, monoamine oxidase inhibitors, and statins, have shown some benefit in epidemiological studies and clinical trials although compelling evidence of their efficacy is lacking. Memantine, shown to cause cognitive and functional improvement, is not an ChE inhibitor and does not interact with marketed ChE inhibitors. While the mechanism of action of memantine in AD is not known, the principal pharmacologic actions at therapeutic dose are inhibition of ionotropic neurotransmitter receptors, specifically N-methyl-D-aspartate (NMDA), 5-HT3, and nicotinic receptors. Like other NMDA antagonists, memantine causes behavioral activation associated with enhanced cerebral glucose utilization. Studies have shown that memantine can reverse the decreased metabolic activity associated with AD, possibly accounting for its beneficial effects on cognition and global functioning. Memantine also has neuroprotective properties and can inhibit Aβ-induced neurodegeneration.
What Are the Challenges Faced by Psychiatrists in the Management of Alzheimer's Disease?
Authors: Mintzer Jacobo E.
Published: August 2016

Alzheimer's disease (AD) is a debilitating condition affecting millions of elderly citizens. The quality of life for AD patients significantly deteriorates in the face of worsening cognitive deficits and disabling functional declines, both contributing to manifestations of difficult behaviors. Of the estimated 4 million individuals with AD, only 60% of probable AD cases are diagnosed, with little more than half of those receiving treatment. One of the possible reasons for this problem is the large role primary care physicians (PCPs) have in diagnosing and treating AD. The barriers that PCPs confront to adequately manage these patients will be discussed. Finally, the specific challenges that geriatric psychiatrists will face in addressing these issues in an environment where there is only a limited number of trained geriatric psychiatrists will be discussed, as well as the possible role that new technology could have in finding the solution to this difficult problem.
Obsessive-Compulsive Disorder and Its Potential Subtypes
Authors: Black Donald W.
Published: August 2016

This manuscript summarizes presentations by an international panel of experts, representing Brazil, Israel, Italy, Mexico, Portugal, Spain, and the United States, at a symposium on obsessive-compulsive disorder (OCD) and its possible subtypes. Presentations concerned both OCD proper, as well as putative obsessive-compulsive-spectrum disorders (autistic disorders, eating disorders, pathological gambling, and schizo-obsessive disorder). Projects discussed included a study assessing impulsive temperament in eating disorder patients, a study on serotonin receptor sensitivity in autism, a study of sleep EEG abnormalities in OCD, a study of dissociation in pathological gamblers, papers on aspects of schizo-obsessive patients, a study addressing biological alterations in OCD, data from a new family study on OCD, data from a molecular genetic study of OCD, a factor analytic study of Tourette disorder, a study hypothesizing the existence of an OCD continuum, and, finally, a paper on early- vs late-onset OCD. General discussion followed leading to a consensus that 1) OCD is likely heterogeneous with multiple subtypes; 2) division of patients by age-at-onset probably represents a robust and valid subtyping scheme; 3) the presence of schizophrenic features probably identifies a valid subtype; 4) the validation of subtypes in the future will be informed by both family-genetic studies, as well as studies of biological alterations in OCD; and 5) the study of obsessive-compulsive spectrum disorders adds to our understanding of the OCD phenomenon, and helps in our search to identify valid subtypes.
Treating the Mind and Body in Schizophrenia: Risks and Prevention
Authors: Meyer Jonathan M.
Published: August 2016

Patients with schizophrenia have increased mortality due to higher rates of suicide. However, natural causes of death, such as cardiovascular disease, also contribute greatly to excess mortality. Significant sources of cardiovascular risk in this patient population include high smoking prevalence, inactive lifestyles, poor dietary habits, and the metabolic effects of atypical antipsychotics. These sources of risk interact with underrecognition of common medical conditions by mental health providers, limited access to primary care services, and undertreatment of health conditions in the general medical setting. For many patient with severe mental illness, the mental health setting represents the sole source of medical care, making the psychiatrist the de facto primary care provider for these individuals. With the recent focus on medical consequences of antipsychotic treatment, psychiatrist have an obligation to minimize these adverse effects by choosing antipsychotics with lower risk for metabolic side effects, and becoming familiar with the screening and management of common medical conditions.
Introduction Advances in the Treatment of Mood and Anxiety Disorders
Authors: Nemeroff Charles B. , Radford Mark H.B. , Golden Robert N.
Published: August 2016

Mood and anxiety disorders are prevalent in all countries and cultures, which becomes obvious when standardized diagnostic and evaluation techniques are utilized. It is estimated that ~450 million people worldwide suffer from psychiatric illness. In the United States alone, epidemiologic research has identified that tens of millions of Americans suffer from major depressive disorder (MDD) annually, with many of them being in the prime of their adult lives. In addition to medical, personal, and social costs, depression is also believed to have a significant impact on work productivity. Further epidemiologic research indicates that nearly half of all individuals meeting lifetime criteria for MDD also have met criteria for a comorbid anxiety disorder. With an average age of 16 years for the onset of any lifetime anxiety disorder, anxiety disorders appear to predispose affected individuals to a substantial lifetime risk for MDD. In order to improve outcomes in depression and anxiety disorders, clinicians must enhance the entire process of recognition, diagnosis, and treatment.
Making Advances Where It Matters: Improving Outcomes in Mood and Anxiety Disorders
Authors: Golden Robert N.
Published: August 2016

Mood and anxiety disorders are among the most prevalent psychiatric illnesses and are associated with considerable morbidity and mortality. Selective serotonin reuptake inhibitors (SSRIs) are safe and effective treatments for major depression and anxiety disorders, and have become the most widely prescribed antidepressants worldwide. However, several issues limit SSRI treatment outcomes. Although SSRIs have a wider therapeutic margin and a milder side-effect profile compared to earlier antidepressants, even minor SSRI side effects can have a major impact on treatment outcomes by interfering with patient compliance. Nausea is one of the most common early SSRI side effects, and advances in SSRI delivery systems can diminish this. A controlled-release formulation of paroxetine targets the site of absorption for a more distal region of the small intestine, thereby avoiding the stimulation of upper gastrointestinal serotonin receptors that mediate nausea. The sustained-release characteristics also reduce the amplitude in blood level peaks and troughs, which may lead to diminished side effects and enhanced efficacy. Sexual side effects and weight gain are important sustained SSRI side effects, which affect compliance during continuation and maintenance phases of treatment. Several strategies address SSRI sexual side effects, including the use of adjunctive medication and/or manipulations in the scheduling of drug administration. Depression negatively impacts the management of many medical illnesses, including cardiovascular disease, cancer, and infectious diseases. The recognition and treatment of depression leads to improved outcomes in the management of breast cancer. Prophylactic SSRI treatment significantly reduces the incidence of interferon-associated depression and enhances completion rates in malignant melanoma.
Metabolic and Endocrine Disturbances in Psychiatric Disorders: A Multidisciplinary Approach to Appropriate Atypical Antipsychotic Utilization
Authors: Masand Prakash S. , Culpepper Larry , Henderson David , Lee Scott , Littrell Kimberly , Newcomer John W. , Rasgon Natalie
Published: August 2016

Patients with psychiatric disorders have an increased rate of cardiovascular morbidity and mortality compared with the general population. Metabolic issues such as weight gain, dyslipidemia, diabetes mellitus, diabetic ketoacidosis, and pancreatitis have been reported with the use of antipsychotic agents. Although atypical antipsychotics have not been linked directly to the development of metabolic syndrome, these medications have been shown to increase risk factors that can lead to metabolic and endocrine disturbances. Therefore, clinicians should provide ongoing monitoring for patients who are being treated for psychiatric disorders with these agents. According to the 2004 Consensus Report on Antipsychotics, screening measures should include baseline and follow-up monitoring of personal/family histories, weight (body mass index), waist circumference, blood pressure, fasting plasma glucose, and fasting lipid profile.
Treatment of Bipolar Disorder During the Postpartum Period
Authors: Viguera Adele C.
Published: August 2016

The presentations and clinical courses of patients with bipolar disorder differ greatly by gender. In addition, medical therapy must be tailored differently for men and women because of emerging safety concerns unique to the female reproductive system. In November 2005, these topics were explored by a panel of experts in psychiatry, neurology, and reproductive health at a closed roundtable meeting in Dallas, Texas. This clinical information monograph summarizes the highlights of that meeting.

Compared to men with bipolar disorder, women have more pervasive depressive symptoms and experience more major depressive episodes. They are also at higher risk for obesity and certain other medical and psychiatric comorbidities. Mood changes across the menstrual cycle are common, although the severity, timing, and type of changes are variable. Bipolar disorder is frequently associated with menstrual abnormalities and ovarian dysfunction, including polycystic ovarian syndrome. Although some cases of menstrual disturbance precede the treatment of bipolar disorder, it is possible that valproate and/or antipsychotic treatment may play a contributory role in young women.

Pregnancy does not protect against mood episodes in untreated women. Maintenance of euthymia during pregnancy is critical because relapse during this period strongly predicts a difficult postpartum course. Suspending therapy in the first months of pregnancy may be an option for some women with mild-to-moderate illness, or those with a long history of euthymia during pre-pregnancy treatment. However, a mood stabilizer should be reintroduced either in the later stages of pregnancy or in the immediate postpartum period. Preliminary data suggest that fetal exposure to some mood stabilizers may raise the risk of major congenital malformations and neurodevelopmental delays. For women planning to become pregnant, clinicians may consider switching to other drugs before conception. The value and drawbacks of breastfeeding during treatment must be considered in partnership with the patient, with close monitoring of nursing infants thereafter. The risks and benefits of medical treatment for women with bipolar disorder should be carefully reconsidered at each stage of their reproductive lives, with a flexible approach that is responsive to the changing needs of patients and their families.
Recent Advances in the Understanding and Treatment of Anxiety Disorders
Authors: Stein Dan J.
Published: August 2016

Anxiety disorders are the most prevalent of the psychiatric disorders, account for a significant proportion of mental illness costs, and include some of the most disabling medical disorders. Anxiety disorders, which currently include the obsessive-compulsive disorders, continue to be poorly diagnosed and undertreated across a broad range of countries. It is possible that the universal experience of anxiety as an adaptive emotion makes it more difficult for patients and clinicians to conceptualize symptoms in terms of psychopathology.

Nonetheless, there have been significant advances in our understanding of anxiety and obsessive-compulsive disorders, and in our ability to manage these conditions successfully. Research on anxiety and obsessive-compulsive disorders exemplifies the goals of translational investigation; preclinical work has not only allowed an exploration of known clinical phenomena, but has also led directly to novel clinical interventions. Investigators around the globe are continuing to contribute to research on anxiety and obsessive-compulsive disorders.
Evidence-based Guidelines for Anxiety Disorders: Can They Improve Clinical Outcomes?
Authors: Baldwin David S.
Published: August 2016

Evidence-based medicine (EBM) enables clinicians to justify decision making, enhances the quality of medical practice, identifies unanswered research questions, and ensures the efficient practice of medicine. Implementation of evidence-based mental health programs requires education, time, and improved effort by administration, regulatory, and clinical professionals. Essential to these efforts are consistent incentives for change, effective training materials, and clear clinical guidelines. Guidelines exist within the framework of EBM. Good guidelines are simple, specific, and user friendly, focus on key clinical decisions, are based on research evidence, and present evidence and recommendations in a concise and accessible format. Potential limitations of guidelines to improve clinical outcomes in anxiety disorders are the widespread distribution of anxiety symptoms in primary care, health inequalities across patient groups, persistent misconceptions regarding psychotropic drugs, and low confidence in using simple psychological treatments. Clinical guidelines generally specify therapeutic areas covered and not covered, but often there is no mention of cost or cost effectiveness of treatment. Guidelines can inform clinical decision making, but administrators of drug formularies may regard themselves as being primarily responsible for limiting costs and access to certain medications, even if these decisions are at odds with guideline recommendations.
Applications for Magnetic Resonance Imaging in Bipolar Disorder
Authors: Renshaw Perry F.
Published: August 2016

Bipolar disorder is a prevalent psychiatric disorder with a high rate of misdiagnosis and evidence of degenerative progression. Research indicates that the interval between bipolar episodes decreases steadily until the patient settles into a relatively frequent course of mania and depression. Various imaging techniques have been used in the understanding of the brain pathology underlying bipolar disorder through identification of patterns consistent with disruption of the normal brain activity in bipolar patients. These techniques have demonstrated evidence of abnormalities in the structure and function of the prefrontal cortex. In addition, the cerebellar vermis, which serves as an error-detection function to modulate the iterative network, appears to shrink with recurrent episodes. Functional imaging demonstrates that the anterior limbic network is overactivated and overresponsive in patients with bipolar disorder. In many patients, those deficits are often compensated for by activation of other brain areas. Ultimately, when the compensation fails, expression of bipolar symptoms arise. Using magnetic resonance spectroscopy, simple models can be constructed based on the hypothesis that mitochondrial function may be impaired in bipolar disorder. There is also increasing evidence that psychotropic medications can affect specific brain regions that are thought to be involved in the pathogenesis of psychiatric disorders. Glutamate levels appear to be elevated in untreated patients with bipolar disorder, which may cause glutamatergic neurotoxicity and negative therapeutic implications. Further advances in brain imaging may contribute to the improvement of available therapies and the understanding which treatments will be most suitable for specific patients.
The Nature of Insomnia
Authors: Roth Thomas
Published: August 2016

Insomnia is a disorder characterized by chronic sleep disturbance associated with daytime disability or distress, such as memory impairment and fatigue, that occurs despite adequate opportunity for sleep. Insomnia may present as difficulty falling/staying asleep or as sleep that is nonrestorative. Studies show a strong correlation between insomnia and impaired quality of life. Pain conditions and depression are commonly associated with insomnia, either as secondary or comorbid conditions. In addition, a greater incidence of anxiety, alcohol and drug dependence, and cardiovascular disease is found in people with insomnia. Data indicate insomnia results from over-engaged arousal systems. Insomnia patients experience increased metabolic rate, body temperature, and heart rate, and elevated levels of norepinephrine and catecholamines. Pharmacologic options for the treatment of insomnia include benzodiazepine hypnotics, a selective melatonin receptor agonist, and sedating antidepressants. However, insomnia may be best treated with cognitive-behavioral therapy and instruction in good sleep hygiene, either alone or in concert with pharmacologic agents. Studies on the effects of insomnia treatment use variable methodologies or do not publish negative results, and there are currently no studies of treatment focusing on morbidity. Further research is necessary to better understand the effects of insomnia therapies on medical and psychiatric disorders.

In this Clinical Information Supplement, Thomas Roth, PhD, describes the nature of insomnia and its pathophysiology. Next, Andrew D. Krystal, MD, MS, reviews morbidities associated with insomnia. Finally, Joseph A. Lieberman III, MD, MPH, provides an overview of therapeutics utilized in patients with insomnia, including behavioral therapies and pharmacologic options.
