Depression is commonly treated with a combination of medications and therapies. Cognitive behavioral therapy, behavior therapy, and/or psychotherapy are the most common psychological therapies. Antidepressants and/or antipsychotics will normally also be given along with some form of relaxation techniques. Antidepressant medications are used to increase certain levels of the brain’s neurotransmitters. Sometimes natural lifestyle changes may also be utilized, such as exercise and healthy eating. Severe depression may be treated with ECT (electroconvulsive therapy).
