Link found between traumatic brain injury and Parkinson's, but not Alzheimer's

Traumatic brain injury (TBI) with a loss of consciousness (LOC) may be associated with later development of Parkinson's disease but not Alzheimer's disease or incident dementia, according to a study conducted at the Icahn School of Medicine at Mount Sinai and the University of Washington School of Medicine. The research, published today in JAMA Neurology, contradicts common assumptions about the relationship between TBI and Alzheimer's disease as found in other high-profile studies.
