Abstract

To investigate the prevalence and symptomatology of depression in Parkinson's disease (PD), we have studied 506 unselected patients attending the neurology services in French general hospitals during a 5 month period defined for prospective inclusion. 246 patients (48.6%) were suspected of depression according to different methods of evaluation and 168 (33.2%) were defined as definite or probable depression. According to the Montgomery and Asberg scale, 46 cases (9%) had a severity score suggestive of major depression. As a function of the cut-off score defined for severity, these patients represented from 23.2 to 43.7% of the depressive population with PD. There was no significant difference between depressed and non depressed PD patients as a function of the patient's current age or age at onset of PD. A significantly higher rate of depression was found among women with PD. A past history of depression was a risk factor for mood disorder after onset of PD. The severely depressed patients had a significantly longer duration of PD and a higher score of cognitive impairment than mildly or moderately depressed and non depressed patients with PD. Depressed patients had a significantly more advanced stage of disability than non-depressed patients with PD.
