Psychosocial Treatment of Depression in Parkinson's Disease

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to examine the effects of a form of talk therapy called cognitive behavior therapy (CBT) in the treatment of major depression in individuals with Parkinson's disease (PD).

Detailed Description
-----------------
CBT is a specific type of treatment that has been shown to be as helpful in treating depression as medications for depression. CBT focuses on thoughts, feelings, and behaviors. It focuses on the here and now, rather than the past. CBT offers concrete strategies and skills for coping with depression, PD, and other life problems. Previous research leads us to believe that this type of therapy may help people with PD cope with their depression.
