Parkinson's disease (PD) is generally considered a neurological disorder.  However, because of the frequency of mood and other psychiatric complications PD could also be considered as a neuropsychiatric disease.  In fact, James Parkinson himself observed in 1817 that depression is commonly associated with PD.

The estimated prevalence of depression in PD varies according to the type of mood assessment applied, the diagnostic criteria or definition of depression and the research setting.  Depression can be difficult to diagnose in PD because of the overlap between symptoms of depression and PD.  This supplement is designed to walk you through the research on PD and Parkinson's disease.
