A History of Head Trauma May Predict Parkinson Progression
A history of head trauma may predict a more rapid decline in patients with Parkinson's disease (PD), new research suggests. In a longitudinal online study, among patients with PD who had a history of head injury, motor impairment developed 25% faster and cognitive impairment developed 45% faster than among those without such a history. In addition, severe head injuries were associated with an even more rapid onset of impairment.
@debangshu Head injury is a risk factor for PD, but its relationship to PD progression is not well established. There has always been this concern in PD that maybe it's problems with motor impairment that lead to head injuries, so reverse causality is an issue. The analysis was part of the online Fox Insight study that is evaluating motor and nonmotor symptoms in individuals with and those without PD. The study included participants who had completed questionnaires on such things as head trauma.
