title: An analysis of the prevalence and etiology of depression in Parkinson's disease.
abstract: Depression in patients with Parkinson's disease (PD) is a significant clinical problem for which the etiological basis remains unclear. Several authors have asserted it to be a reactive state to progressive, disabling symptoms, whereas others have suggested a neurochemical basis. Recent evidence suggests serotonin deficiencies as a plausible explanation.
