Abstract |
The aim was to analyze prospectively the association between severe head injury and Parkinson's disease. All people in Denmark who were at least 20 years old as on 1 January 1981 were followed for hospitalisation due to previous head trauma during 1981-1993 and for hospital contacts due to PD during 1995-2004. We observed 107 cases of PD among people at hypothetical risk due to previous head injury. The expected number was 112.1, which yielded a standardised morbidity ratio of 0.954 (95% CI: 0.782-1.15). The study provides no support for severe head injury among adults being a risk factor for Parkinson's disease. Language: en |
