Summaries for Major Depressive Disorder

Genetics Home Reference : 25 Seasonal affective disorder is a mental health condition that is triggered by the changing of the seasons. This condition is a subtype of major depressive disorder and bipolar disorder. Major depressive disorder is characterized by prolonged sadness and a general lack of interest, while bipolar disorder is characterized by similar depressive episodes alternating with periods of abnormally high energy and activity (hypomania or mania). People with seasonal affective disorder have signs and symptoms of either major depressive disorder or bipolar disorder only during certain months of the year. Major depressive disorder is more common than bipolar disorder among people with seasonal affective disorder. This condition usually begins in a person's twenties or thirties. The signs and symptoms that occur during depressive episodes in people with seasonal affective disorder are similar to those of major depressive disorder, including a loss of interest or enjoyment in activities, a decrease in energy, a depressed mood, and low self-esteem. In most people with seasonal affective disorder, depression and other features appear in the fall and winter months and subside in the spring and summer months. In these individuals, additional symptoms often include weight gain due to increased cravings for carbohydrates and an increase in sleep (hypersomnia). Affected individuals with underlying bipolar disorder typically have alternating episodes of depression in the fall and winter months and mania during the spring and summer months. In about 10 percent of people with seasonal affective disorder, the condition has the opposite seasonal pattern, occurring in the spring and summer months and stopping during the fall and winter months. These individuals usually have a loss of appetite and sleep, unlike those with symptoms in the fall and winter. For those affected, it is estimated that symptoms of seasonal affective disorder are present during 40 percent of the year. In some individuals, seasonal affective disorder does not recur every year. Thirty to 50 percent of affected individuals do not show symptoms of the disorder in consecutive winters. In about 40 percent of individuals with seasonal affective disorder, depressive episodes continue after winter and do not alleviate in the summer months, leading to a change in diagnosis to either major depressive disorder or bipolar disorder. Individuals with seasonal affective disorder tend to have another psychological condition, such as attention-deficit/hyperactivity disorder (ADHD), an eating disorder, anxiety disorder, or panic disorder.

MalaCards based summary : Major Depressive Disorder, also known as seasonal affective disorder, is related to depression and mental depression, and has symptoms including mental and behavioral signs and symptoms and depressive symptoms. An important gene associated with Major Depressive Disorder is HTR2A (5-Hydroxytryptamine Receptor 2A), and among its related pathways/superpathways are Serotonergic synapse and Circadian rythm related genes. The drugs Etomidate and Valsartan have been mentioned in the context of this disorder. Affiliated tissues include brain, cortex and testes, and related phenotype is behavior/neurological.

Disease Ontology : 12 An endogenous depression that is characterized by an all-encompassing low mood accompanied by low self-esteem, and by loss of interest or pleasure in normally enjoyable activities.

MedlinePlus : 42 Seasonal affective disorder (SAD) is a type of depression that comes and goes with the seasons. It usually starts in the late fall and early winter and goes away during the spring and summer. Some people do have episodes of depression that start in the spring or summer, but that is a lot less common. Symptoms of SAD may include Sadness Gloomy outlook Feeling hopeless, worthless, and irritable Loss of interest or pleasure in activities you used to enjoy Low energy Difficulty sleeping or oversleeping Carbohydrate cravings and weight gain Thoughts of death or suicide SAD is more common in women, young people, and those who live far from the equator. You are also more likely to have SAD if you or your family members have depression. The exact causes of SAD are unknown. Researchers have found that people with SAD may have an imbalance of serotonin, a brain chemical that affects your mood. Their bodies also make too much melatonin, a hormone that regulates sleep, and not enough vitamin D. The main treatment for SAD is light therapy. The idea behind light therapy is to replace the sunshine that you miss during the fall and winter months. You sit in front of a light therapy box every morning to get daily exposure to bright, artificial light. But some people with SAD do not respond to light therapy alone. Antidepressant medicines and talk therapy can reduce SAD symptoms, either alone or combined with light therapy. NIH: National Institute of Mental Health

KEGG : 36 Major depressive disorder (MDD) is the most common psychiatric disorder mainly characterized by depressed mood, loss of interest, feelings of worthlessness, and a high risk of suicide. Accumulated evidence suggests that both environmental and genetic factors are involved in the etiology of MDD although the pathogenesis of MDD remains unknown. Mutations in genes involved in brain serotonin synthesis, have been identified in patients. Brain serotonin deficiency has been hypothesized to play a role in a wide range of psychiatric diseases, including MDD. Several efficacious treatments for MDD are available, including different forms of psychotherapy and antidepressant medication. Recently, selective reuptake inhibitors (SSRIs, SNRIs,) have become the first-line antidepressant drug treatment of depression and replaced tricyclic antidepressants (TCA) and monoamine oxidase inhibitors (MAOI) due to fewer side-effects and ease of use.

UniProtKB/Swiss-Prot : 73 Major depressive disorder: A common psychiatric disorder. It is a complex trait characterized by one or more major depressive episodes without a history of manic, mixed, or hypomanic episodes. A major depressive episode is characterized by at least 2 weeks during which there is a new onset or clear worsening of either depressed mood or loss of interest or pleasure in nearly all activities. Four additional symptoms must also be present including changes in appetite, weight, sleep, and psychomotor activity; decreased energy; feelings of worthlessness or guilt; difficulty thinking, concentrating, or making decisions; or recurrent thoughts of death or suicidal ideation, plans, or attempts. The episode must be accompanied by distress or impairment in social, occupational, or other important areas of functioning.
