Is it possible to overcome depression with psychotherapy, without medication?
Often, though medication may sometimes reduce suffering and speed up the process. However, if the person is manic or has severe vegetative symptoms of depression he will probably not be in a fit state to do psychotherapy without medication. In the case of the elderly, depression can be caused by the effects of some medications and some illnesses on the body chemistry. Lack of physical activity or low levels of light in northern winters can also contribute to depression. Physical problems like these need to be corrected by physical methods.
