Parkinsonism can be caused by repeated blows to the head, such as a professional boxer may experience. Chronic traumatic brain injury associated with boxing can also be associated with dementia (dementia pugilistica). Usually, this kind of parkinsonism is not as responsive to levodopa. The risk associated with a single head injury, such as in a car crash, and Parkinson’s disease has not been established, although one twin study reported that it may increase the risk of PD decades later.
