Dementia is more likely to occur in people who have had a head injury in the past. in car accidents, in sports or in fights, shows new American scientific study.
The risk is greater for women than,what about men.
Researchers from the University of Pennsylvania School of Medicine, headed by Dr. Andrea Snyder, published in the journal Alzheimer's and Alzheimer's Disease & Dementia: The Journal of the Alzheimer’s Association», analyzed data for a group of middle-aged people 54 years, which were monitored in depth 25 years.
It was found that, compared to those who had never suffered a serious head injury, those who once had such an injury, then they had 1,25 times (25%) greater risk of dementia, while those with a history of two or more head injuries had more than double the risk of dementia. As estimated, almost the 10% all cases of dementia could be attributed to at least one previous head injury.
Scientists are constantly updated that the consequences of such injuries can have long-term consequences..
"A head injury is a significant risk factor for dementia, but it is something that could be prevented. Our findings, however, show that the more such injuries there are the greater the risk of dementia ", Snyder said, stressing that the issue needed further study.
