Context_1 : Thalia Catherine Eley is a Professor of Developmental Behavioural Genetics at the Institute of Psychiatry's MRC Social, Genetic and Developmental Psychiatry Centre, King's College London. Her work focuses on the interplay between genetic and environmental factors on the development and treatment of anxiety and depression. Context_2 : Lori Altshuler (born August 23, 1957) was a Professor at the University of California, Los Angeles (UCLA) Department of Psychiatry and Biobehavioral Sciences and held the Julia S. Gouw Endowed Chair for Mood Disorders. Dr. Altshuler was the Director of the UCLA Mood Disorders Research Program and the UCLA Women’s Life Center, each being part of the Neuropsychiatric Hospital at UCLA. Context_3 : Cognitive disorders are a category of mental health disorders that primarily affect learning, memory, perception, and problem solving, and include amnesia, dementia, and delirium. While anxiety disorders, mood disorders, and psychotic disorders can also have an effect on cognitive and memory functions, the DSM-IV-TR does not consider these cognitive disorders, because loss of cognitive function is not the primary (causal) symptom. Context_4 : Depression is a state of low mood and aversion to activity that can affect a person's thoughts, behavior, feelings, and sense of well-being. A depressed mood is a normal temporary reaction to life events such as loss of a loved one. It is also a symptom of some physical diseases and a side effect of some drugs and medical treatments. Depressed mood is also a symptom of some mood disorders such as major depressive disorder and dysthymia. Context_5 : Alimemazine (INN), also known as trimeprazine (USAN and former BAN); brand names Nedeltran, Panectyl, Repeltin, Therafene, Theraligene, Theralen, Theralene, Vallergan, Vanectyl, and Temaril), commonly provided as a tartrate salt, is a phenothiazine derivative that is used as an antipruritic (it prevents itching from causes such as eczema or poison ivy, by acting as an antihistamine). It also acts as a sedative, hypnotic, and antiemetic for prevention of motion sickness. Although it is structurally related to drugs such as chlorpromazine, it is not used as an antipsychotic. In the Russian Federation, it is marketed under the brand name Teraligen for the treatment of anxiety disorders (including GAD), organic mood disorders, sleep disturbances, personality disorders accompanied by asthenia and depression, somatoform autonomic dysfunction and various neuroses. Context_6 : Social anxiety can be defined as nervousness in social situations. Some disorders associated with the social anxiety spectrum include anxiety disorders, mood disorders, autism, eating disorders, and substance use disorders. Individuals higher in social anxiety avert their gazes, show fewer facial expressions, and show difficulty with initiating and maintaining conversation. Trait social anxiety, the stable tendency to experience this nervousness, can be distinguished from state anxiety, the momentary response to a particular social stimulus. Nearly 90% of individuals report feeling a form of social anxiety (i.e., shyness) at some point in their lives. Half of the individuals with any social fears meet criteria for social anxiety disorder. The function of social anxiety is to increase arousal and attention to social interactions, inhibit unwanted social behavior, and motivate preparation for social situations such as performance situations. Context_7 : Hagop Souren Akiskal (Armenian: Հակոբ Սուրեն Ակիսկալ , born 1944) is an Armenian-American psychiatrist best known for his research on temperament and bipolar disorder (manic depression). Born in Lebanon to Armenian parents, he received his M.D. from the American University of Beirut in 1969. He completed his residency training in psychiatry at University of Wisconsin–Madison, and then worked for several years as a clinician and mood disorders researcher at the University of Tennessee, Memphis. He was senior science advisor at NIMH from 1990–1994, before moving to the University of California, San Diego, where he is currently professor of psychiatry. Today's leading conceptual thinker in the area of bipolar subtyping, Akiskal is a fastidious researcher and an astute clinical observer. He is a devotee of Emil Kraepelin; he believes that the nosologic (classification) pendulum is gradually swinging back towards Kraepelin's original unitary concept of the bipolar spectrum of mood disorders (Lieber, Arnold). Context_8 : The affective spectrum is a spectrum of affective disorders (mood disorders). It is a grouping of related psychiatric and medical disorders which may accompany bipolar, unipolar, and schizoaffective disorders at statistically higher rates than would normally be expected. These disorders are identified by a common positive response to the same types of pharmacologic treatments. They also aggregate strongly in families and may therefore share common heritable underlying physiologic anomalies. Context_9 : Evolutionary approaches to depression are attempts by evolutionary psychologists to use the theory of evolution to shed light on the problem of mood disorders. Depression has generally been thought of as dysfunction, but it is much more common than schizophrenia or autism, and its prevalence does not increase with age the way dementia and other organic dysfunction commonly does. Some researchers have surmised that the disorder may have evolutionary roots, in the same way that others suggest evolutionary contributions to schizophrenia, sickle cell anemia and other disorders. Psychology and psychiatry have not generally embraced evolutionary explanations for behaviors, and the proposed explanations for the evolution of depression remain controversial. Context_10 : Depression is a state of low mood and aversion to activity. It may be a normal reaction to occurring life events or circumstances, a symptom of a medical condition, a side effect of drugs or medical treatments, or a symptom of certain psychiatric syndromes, such as the mood disorders major depressive disorder and dysthymia. Depression in childhood and adolescence is similar to adult major depressive disorder, although young sufferers may exhibit increased irritability or aggressive and self-destructive behavior, rather than the all-encompassing sadness associated with adult forms of depression. Children who are under stress, experience loss, or have attention, learning, behavioral, or anxiety disorders are at a higher risk for depression. Childhood depression is often co-morbid with mental disorders outside of other mood disorders; most commonly anxiety disorder and conduct disorder. Depression also tends to run in families. Psychologists have developed different treatments to assist children and adolescents suffering from depression, though the legitimacy of the diagnosis of childhood depression as a psychiatric disorder, as well as the efficacy of various methods of assessment and treatment, remains controversial. fact_1 :  Her work focuses on the interplay between genetic and environmental factors on the development and treatment of anxiety and depression. fact_2 :  Depressed mood is also a symptom of some mood disorders such as major depressive disorder and dysthymia. Question: What are two mood disorders that Thalia Catherine Eley would come across in her study of depression?
Output: depressive disorder and dysthymia
