title: Serotonergic dysfunction in depression associated with Parkinson's disease.
abstract: A 55-year-old man presented with a 5-year history of Parkinson's disease and a 6-month history of major depression. The patient's depressive symptoms responded to treatment with fluvoxamine, a selective and potent serotonin reuptake inhibitor. Tryptophan depletion testing, which acutely lowers central serotonin levels, caused a brief exacerbation of the depressive illness, which resolved upon tryptophan repletion. Serotonergic dysfunction may be an etiologic factor in depression that occurs in Parkinson's disease.
