  1. Risk of dementia in patients with Parkinson's disease, epilepsy, and severe head trauma : a register-based follow-up study.

    Article - En anglais

    The authors investigated the risk of developing dementia for persons aged 50-75 years who suffered from Parkinson's disease, epilepsy, or severe head trauma.

    They compared the risk in this patient group with the risk in a reference group in a follow-up study based on the linked databases of three Dutch nationwide morbidity registers over the years 1980-1989.

    The overall relative risk of developing dementia within 8 years in patients with Parkinson's disease who were initially free of dementia was 3.0 (95% confidence interval (CI) 2.9-3.1).

    Risk was especially increased in younger Parkinson's disease patients (relative risk (RR)=13.2,95% CI 6.2-28.6).

    For patients with epilepsy, the overall relative risk was 1.5 (95% CI 1.4-1.7).

    Severe head trauma was not associated with an increased risk of dementia (RR=1.0,95% CI 0.9-1.1).

    These findings suggest that Parkinson's disease is an important risk factor for dementia, with a particularly high risk in young patients with Parkinson's disease.

    Patients with epilepsy may bear a moderately increased risk of developing dementia.

    This study does not support earlier findings in retrospective case-control studies of an increased risk of dementia in head trauma patients.
