Effects of the Female Reproductive System on Bipolar Disorder
Authors: Ketter Terence A. 
Published: August 2016

AbstractThe 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.

Comorbidity and Diagnosis of ADHD
Authors: Reimherr Frederick W. 
Published: August 2016

AbstractAttention-deficit/hyperactivity disorder (ADHD), once considered to be a childhood disorder, is diagnosed in ~7 million adults in the United States, as reported by The National Comorbidity Study. Although it is now recognized that ADHD often persists into adulthood, the current diagnostic criteria is geared toward symptom identification in children. Symptoms of inattention, impulsivity, and hyperactivity evolve over the life cycle and present differently in adults. Further complicating diagnosis is that ADHD is associated with multiple functional impairments and comorbid psychiatric disorders. The Multi-Modal Treatment Study of ADHD reported that only 32% of the study population had ADHD alone; 29% had ADHD plus oppositional defiant disorder and/or conduct disorder, 14% had ADHD plus anxiety or depression, and 25% had all three disorders. Optimal treatment utilizes a multi-modal approach including behavioral treatments combined with pharmacologic treatment strategies. Food and Drug Administration-approved medications for ADHD include the stimulants and nonstimulants, although tricyclic antidepressants and bupropion are also commonly used.In this monograph, Craig L. Donnelly, MD, reviews the history of ADHD and discusses the pathophysiologic progression of childhood symptoms into those commonly exhibited by adults. Next, Frederick W. Reimherr, MD, reviews comorbidity of ADHD and describes the Utah Criteria as a method of diagnosing adults through recollection of childhood problems. Finally, Joel L. Young, MD, reviews treatment approaches to adult ADHD and its comorbid conditions.
Calming the Bipolar Storm: Treating Acute Mania and Mixed Episodes in Patients with Bipolar Disorder
Authors: Zajecka John M. 
Published: August 2016

AbstractBipolar disorder is a seriously debilitating psychiatric disorder that greatly affects patients and their loved ones. Although bipolar disorder is one of the most frequently occurring mental disorders worldwide, many patients, particularly those with mixed mania, remain misdiagnosed. Compared to pure mania, mixed episodes of bipolar disorder present with symptoms that can be more challenging to treat. However, proper diagnosis and early treatment can usually alter the course of the illness, and remission is certainly possible.This expert roundtable supplement reviews the differences between acute manic and mixed episodes in patients with bipolar disorder, explains proper dosing and the advantages of different dosage formulations, and identifies the rationale for monotherapy and combination therapy in these patient populations. The aim is to educate clinicians about ways to diagnose and treat the mood state aggressively and safely, especially in light of the many new treatment options available.
Introduction: Amyloid-Based Interventions in Alzheimer's Disease
Authors: Kennedy Gary J. 
Published: August 2016

AbstractWe appear to be on the brink of a new epoch of treatment for Alzheimer's disease. Compelling evidence suggests that Aβ secretion is the triggering event in the pathogenesis of Alzheimer's disease, and that tau aggregation may be an important secondary event linked to neurodegeneration. Prophylactic administration of anti-amyloid agents designed to prevent Aβ accumulation in persons with subclinical disease is likely to be more effective than therapeutic interventions in established Alzheimer's disease. Drug development programs in Alzheimer's disease focus primarily on agents with anti-amyloid disease-modifying properties, and many different pharmacologic approaches to reducing amyloid pathology and tauopathy are being studied. Classes of therapeutic modalities currently in advanced-stage clinical trial testing include forms of immunotherapy (active β-amyloid immunoconjugate and human intravenous immunoglobulin), a γ-secretase inhibitor, the selective Aβ42-lowering agent R-flurbiprofen, and the anti-aggregation agent tramiprosate. Non-traditional dementia therapies such as the HMG-CoA reductase inhibitors (statins), valproate, and lithium are now being assessed for clinical benefit as anti-amyloid disease-modifying treatments. Positive findings of efficacy and safety from clinical studies are necessary but not sufficient to demonstrate that a drug has disease-modifying properties. Definitive proof of disease-modification requires evidence from validated animal models of Alzheimer's disease; rigorously controlled clinical trials showing a significantly improved, stabilized, or slowed rate of decline in cognitive and global function compared to placebo; and prospectively obtained evidence from surrogate biomarkers that the treatment resulted in measurable biological changes associated with the underlying disease process.
Neurobiology and Functional Progression in Schizophrenia
Authors: Jarskog L. Fredrik 
Published: August 2016

AbstractSchizophrenia is a neurodevelopmental disorder associated with persistent symptomatology, severe functional disability, and residual morbidity characteristic of neurodegenerative brain diseases. The illness begins with genetic susceptibility and generally expresses itself after puberty through subtle changes that begin during the prodromal stage. Symptoms get progressively worse and tend to become more resistant to treatment with each relapse. Evidence for a neuroprotective effect of some forms of early treatment is beginning to emerge. While the underlying mechanisms remain uncertain, atypical antipsychotics may counteract some of the progressive deteriorative effects by enhancing synaptic plasticity and cellular resilience. However, identifying and treating patients in the earliest disease states presents methodological challenges as there is no consensus on the best methods of intervention and differences in at-risk children are not readily detectable or substantial enough to predict which ones will develop schizophrenia.In this expert roundtable supplement, Jeffrey A. Lieberman, MD, reviews the historical context of progressive deterioration in schizophrenia. Next, Diana O. Perkins, MD, MPH, reviews some of the challenges to early identification of illness as well as the impact of early versus delayed treatment. Finally, L. Fredrik Jarskog, MD, focuses on the neurobiology of functional progression in schizophrenia as well as pharmacology and the potential for neuroprotection.
Pharmacology of Adult ADHD with Stimulants
Authors: Spencer Thomas J. 
Published: August 2016

AbstractAttention-deficit/hyperactivity disorder (ADHD) is a lifelong condition that begins in childhood and continues with adult manifestations related to the core symptoms. Approximately 50% to 75% of children with ADHD continue to meet criteria for the disorder as adolescents and adults. Adults with the disorder increasingly present to primary care physicians, psychiatrists, and other practitioners for diagnosis and treatment. Understanding the diagnosis of ADHD in adults requires knowledge of age-dependent decline of symptoms over time. Retrospective recall of symptoms and impairment are valid methods of diagnosing the disorder. ADHD is also a brain disorder with a strong neurobiologic basis, complex etiology, and genetic component. Genetic and environmental vulnerabilities give rise to abnormalities in the brain and subsequent behavioral and cognitive deficits, which may produce the symptoms associated with ADHD. Magnetic resonance imaging studies of ADHD have provided evidence that abnormalities in the brain are caused by the disorder itself rather than treatment of the disorder. Psychiatric comorbidity is common among patients with ADHD and tends to complicate treatment. Acute and long-term use of long-acting stimulant formulations (methylphenidate and amphetamine compounds) have shown robust efficacy and tolerability consistent with the treatment response established in children with ADHD. Non-stimulant medications have demonstrated efficacy as well, and may be preferred in patients with tic and substance use disorders.In this expert roundtable supplement, Timothy E. Wilens, MD, reviews the epidemiology and clinical presentation of adult ADHD. Next, Joseph Biederman, MD, provides an overview of recent advances in the neurobiology of ADHD. Thomas J. Spencer, MD, reviews stimulant treatment of adult ADHD, and Lenard A. Adler concludes with a discussion of non-stimulant trials in adult ADHD.
The PHARMO System
Authors: Herings Ron M.C. 
Published: August 2016

AbstractPharmacoepidemiology, the study of the effects of drugs in large numbers of people, is a relatively new discipline that applies the methods of epidemiology to clinical pharmacology. Premarketing clinical trials remain the only way to scientifically determine whether a drug is causally effective, yet these trials do not provide information that allows for estimates about rare, late, or off-label toxicities associated with the drug in question. Increasing concern about common and debilitating adverse effects of medications has highlighted the need for enhanced postmarketing surveillance to follow up on clinical trials. There is a further concern regarding the broader issue of the risk-benefit ratio of certain medications. Computerized databases are a good source of information on which to lay the foundations of postmarketing research. A system of cross-linked computerized medical records may better enable researchers and physicians to realistically monitor postmarketing safety and incorporate monitoring benefits. The same research could also elucidate the net public health effect of regulatory decisions. The Veterans Affairs database in the United States and PHARMO in the Netherlands may represent good models on which to base future postmarketing surveillance studies.In this expert roundtable supplement, Brian L. Strom, MD, provides an overview of the appropriate use of large computer databases in pharmacoepidemiology studies. Philip Wang, MD, DrPH, discusses the advantages of pharmacoepidemiologic studies over clinical trials in correctly detecting drug safety issues. Francesca Cunningham, PharmD, reviews a large computer database that is currently in use within the VA healthcare system, and Ron M.C. Herings, PharmD, PhD, discusses the development of the PHARMO system in the Netherlands.
Management of Substance Use Disorder in Schizophrenia Patients: Current Guidelines
Authors: Drake Robert E. 
Published: August 2016

AbstractSubstance use disorder is the most frequent and clinically significant comorbidity among schizophrenia patients today. All schizophrenia patients should be assessed and monitored carefully regarding their substance use. Those with any regular use of alcohol or other drugs should be considered at risk for multiple adverse effects. As therapies for co-occurring substance use disorders have evolved over the past 20 years, medication management, psychosocial interventions, and rehabilitation models have increasingly emphasized the integration of mental health and substance abuse treatments, attention to group and residential interventions, matching interventions to stage of treatment, comprehensiveness, and long-term perspectives on recovery. Clinicians should understand the implications of each of these principles of care.
Introduction: Selecting an Antidepressant
Authors: Zimmerman Mark 
Published: August 2016

Four years ago, my colleagues and I published an article titled “Why isn't bupropion the most frequently prescribed antidepressant?” The goal of that article was not to advocate bupropion as the preferred agent for treating depression, but rather to stimulate discussion about how psychiatrists choose an antidepressant as well as to highlight the gap between results of efficacy studies and clinical decision making in real-world practice.The argument in support of bupropion being the preferred antidepressant was based on three premises: all antidepressants are equally effective; adverse effects (AEs) of greatest concern to patients who take antidepressants are weight gain and sexual dysfunction; and bupropion does not cause either of these AEs. Acceptance of these three premises suggested the title of that article.Although many reviews of the antidepressant literature, including the revised American Psychiatric Association Practice Guideline for the Treatment of Major Depressive Disorder, conclude that antidepressants are equally effective in general, several experts in the treatment of depression have suggested that medications with >1 mechanism of action may be more effective than agents that have more selective neurotransmitter effects. In a meta-analysis of eight studies comparing the remission rates in patients treated with the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine or selective serotonin reuptake inhibitors (SSRIs), Thase and colleagues demonstrated that venlafaxine was more effective than SSRIs in achieving remission in depressed patients. However, these conclusions were tentative as most of the included studies were comparisons of venlafaxine and fluoxetine; only one study included sertraline, and there were no studies of citalopram included in the review. In addition, patients who had previously failed treatment with an SSRI were not excluded, and, although patients who fail with one SSRI may respond to subsequent treatment with another SSRI, the inclusion of SSRI failures may favor venlafaxine in comparisons with SSRIs. Lastly, all of the studies included in the meta-analysis were funded by the manufacturer of venlafaxine.
Considering Race and Ethnicity During Psychopharmacologic Interventions
Authors: Stewart Altha 
Published: August 2016

The role of race and ethnicity in psychiatric diagnosis and treatment has received increased attention over the last 2 decades. In addition, recent studies conducted to determine the effects of psychotropic drugs among various racial and ethnic groups highlight the importance of considering race and ethnicity during psychopharmacologic interventions.Information regarding differences in drug metabolism, effectiveness, and incidence of adverse effects provides opportunities for psychiatrists to adjust pharmacologic treatment to achieve optimal treatment outcomes while minimizing intolerable side effects. These differences have been explained by inconsistencies in access, stigma, fear of medicines, differing spiritual and cultural beliefs about mental illness, and general mistrust of the healthcare system by many racial and ethnic groups.The articles in this supplement offer a significant contribution to the scientific foundation needed to minimize the patient and clinician factors contributing to the current disparities in mental health care. Recent data, such as those presented in this supplement, describe the role of ethnicity in the pharmacologic treatment of psychiatric disorders and offer hope for improved quality of care for ethnically diverse patient populations. The authors discuss differences in drug metabolism, the impact of these differences on development of various metabolic disorders, and how these differences may be useful in managing intolerable side effects and improving patient compliance and treatment outcome. The information included in these articles should assure that clinical decision making and prescribing practices include sensitivity to safety, tolerability, and dosing for an increasingly ethnically diverse population.
The Ethnopharmacology of Atypical Antipsychotics
Authors: Bradford L. DiAnne 
Published: August 2016

AbstractSince the risk of antipsychotic-induced adverse events is often related to plasma drug concentrations, factors that influence the metabolic transformation of these agents can substantially influence this risk. The cytochrome P450 (CYP) enzyme system, particularly CYP2D6, is very important for the metabolism of many typical and atypical antipsychotic agents. However, there is substantial ethnic/racial pharmacogenetic variability in the phenotypic (ie, metabolic rate) or genotypic (ie, presence of functional or nonfunctional alleles) expression of these enzyme systems. Caucasians have a bimodal distribution of CYP2D6 enzyme activity, with individuals classified either as extensive or poor metabolizers. In contrast, while there are few poor metabolizers among people of Asian descent, a substantial proportion of this population exhibits an intermediate rate of metabolism. African American populations also have a substantial number of intermediate metabolizers, and about the same number of poor metabolizers as Caucasians. Mexican Americans may have a slightly higher metabolic rate than other ethnic groups. Numerous studies have demonstrated that CYP2D6 metabolic status influences the clearance of conventional and atypical antipsychotics. African Americans and Asians, with CYP2D6 phenotypes or genotypes indicative of poor metabolizers, frequently exhibit significantly higher plasma drug concentrations and longer half-lives compared to extensive metabolizers. Importantly, this increased drug exposure is associated with an increased risk of extrapyramidal symptoms. Data on metabolic polymorphism of antipsychotics are lacking among African Americans. There are also some data suggesting that genetic polymorphism can influence the risk of antipsychotic-induced weight gain. These findings highlight the need to consider race/ethnicity when prescribing, dosing, and monitoring antipsychotic agents.
