Depression Depression is a mental illness in which a person experiences deep, unshakable sadness and diminished interest in nearly all activities. Depression usually begins during a person’s 20's or 30's. The illness may come on slowly, then deepen gradually over months or years. On the other hand, it may erupt suddenly in a few weeks or days. There are 3 types of depression; major depression, Bipolar depression, and seasonal affective disorder. Many of them come from anxiety or a situation which caused the person to become extremely depressed. Seasonal affective disorder is felt only during autumn and winter, when there are few hours of daylight. Many things can cause depression. Sometimes it is caused from a high amount of stress and conflicts in a person’s life. Some depressions seem to come suddenly, even when things are going well. Most psychologists believe depression results from an interaction between stressful life events and a person’s biological and psychological vulnerabilities. Genes may also influence depression by causing abnormal activity in the brain. Neurotransmitters in the brain play an important role in regulating moods and emotions. Neurotransmitters involved in depression include norepinephrine, dopamine, and serotonin.
