HealthDay (3/10, Mann) reports, “Sustaining just one head injury may up your chances of developing dementia decades later by 25%, and this risk increases with each subsequent head injury,” investigators concluded after analyzing “25 years of data on more than 14,000 people in the Atherosclerosis Risk in Communities Study.” The study also revealed that “a history of two or more head injuries was associated with more than two times the risk of developing dementia 25 years later.” The findings were published online in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
