What are the treatments for Antidepressant Medications?

The cause of depression is largely unknown, although several theories exist. One theory is that depression is due to the reduced function of one or more neurotransmitter chemicals in the brain such as norepinephrine, dopamine, or serotonin. Another theory that has been researched is that chemical receptor sites may not optimally bind the chemicals serotonin or norepinephrine. Other factors that may affect why some people are more likely to experience depression include the following:
  • heredity and family history of depression,
  • personality,
  • lower socioeconomic status,
  • medical conditions,
  • medications,
  • substance abuse,
  • advanced age,
  • sex (females have a higher incidence),
  • lack of social support, and
  • inadequate diet.
Risks of depression Depression interferes with the ability to perform routine daily tasks and take care of oneself or others. Appetite changes, weight loss or gain, energy loss, inability to sleep, or excessive sleep may accompany depression. Suicidal thoughts or actions may eventually occur. People with depression who are not adequately treated may also more frequently have other medical problems.
