RÉSUMÉ

OBJECTIVE: Neuroleptics and neuroleptic-like drugs are known to induce parkinsonism, which may reveal underlying Parkinson disease (PD) in some cases. We assessed the long-term risk of developing PD after past exposure to these drugs, in a 15-year prospective population-based elderly cohort study. METHODS: We used the Cox proportional hazards model to assess the relation between past exposure to neuroleptics and the risk of developing incident PD. All incident cases of parkinsonism were identified by standardized procedure and validated by a committee of experts. RESULTS: Of 2,991 subjects followed, 117 developed parkinsonism and 43 developed probable PD during follow-up, of whom 22.2% and 32.6%, respectively, had been exposed to neuroleptics, compared to 16.6% for subjects without parkinsonism. About a third of subjects presented transient parkinsonism during drug exposure. After adjustment for gender and past occupation, past exposure to neuroleptics was associated with incident PD (relative risk, 3.16; 95% confidence interval [CI], 1.65-6.04). The relative risk was 3.65 (95% CI, 1.41-9.45) for benzamides and 2.59 (95% CI, 1.23-5.43) for phenothiazines. The population-attributable fraction of the risk for developing PD was 8.2% for benzamides and 12.2% for phenothiazines. CONCLUSIONS: In a French elderly cohort, the risk of probable PD was increased by 3.2-fold after exposure to neuroleptics. This finding suggests the necessity of limiting the use of such drugs in elderly people.

RÉSUMÉ

BACKGROUND: The incidence of dementia in Parkinson's disease (PD) is not fully known, and previous studies have provided a wide range of rates owing to variations in diagnostic criteria and methodologies used. We estimated the risk of dementia in newly diagnosed cases of PD in a population-based cohort of subjects aged >65 years. METHODS: We performed repetitive systematic screening of PD diagnosis, cognitive performances, and clinical dementia during 15 years (at year 0, 3, 5, 8, 10, and 15) in 3726 elderly subjects living at home in southwestern France (PAQUID). Two sets of diagnostic criteria for dementia in PD were considered: Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria and Movement Disorders Society criteria. RESULTS: Forty-four incident cases of PD occurred in the cohort; of these, 18 (41%) developed dementia during a mean follow-up of 6.8 ± 3.6 years. Incidence rate of dementia associated with PD was 74 per 1000 patient-years. The cumulative risk of dementia was approximately 25% and 50% after 5 and 10 years of follow-up, respectively. The relative risk for developing dementia in incident PD subjects compared with non-PD subjects was 2.47 (1.55-3.95). Equivalent estimations were obtained with Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria or Movement Disorders Society criteria. CONCLUSION: PD represents a high-risk stage for dementia in the general population.
