Dopamine deficiency is found in both chronic cocaine abusers and Parkinson's disease. The authors sought to determine whether parkinsonian signs occur in chronic cocaine abusers. Fifty male patients with a history of chronic heavy cocaine abuse were examined on the Unified Parkinson Disease Scale (UPDS) and compared with 20 non‐cocaine‐abusing age‐ and sex‐matched control subjects. UPDS scores of cocaine abusers ranged from 0 to 1 (mean: 0.08 ± 0.28) and, in control subjects, from 0 to 3 (mean: 0.15 ± 0.49; P = 0.5, NS). This study suggests that chronic heavy cocaine abuse does not cause parkinsonism.
