New research at Penn shows that a single head injury could lead to dementia later in life. This risk further increases as the number of head injuries sustained by an individual increases. The findings also suggest stronger associations of head injury with risk of dementia among women compared to among men and among white as compared to among Black populations.
Data from a study of almost 15,000 Americans was obtained over 25 years
Found a single head injury increases the risk of dementia by 25 per cent
Risk is 2.14 times more likely if a person suffers two or more blows to the head
Women are more susceptible than men and white people are more at risk than black people, data shows
