Single head injuries can result to dementia, reported Scottish researchers.

In a recent research carried out by scientists in Scotland and America, a link between head injuries and dementia was traced. Researchers found a large number of proteins in brain of many people who have recovered from a head injury in past. The similarities could be related to Alzheimer’s disease.

The study was carried on 86 people from West Scotland, 39 who had suffered with head injury in past and 47 who did not had history of any such injury. All people were examined after their death. In one third of people who had suffered with head injury, large number of proteins (abnormalities) was traced.

A research was carried out by a team at Southern General Hospital in Glasgow and the University of Pennsylvania in Philadelphia and was in continuation of study.

"The abnormalities that we saw in the brain are normally seen in people with dementia or very old people but we are seeing this in people in their 20s, 30s, and 40s. The proteins are typical of those you might find in Alzheimer's disease”, said Dr William Stewart, team leader in Glasgow and is co-author of the study.

The research will be carried out at a wider scale to get more appropriate results. Website of the journal Brain Pathology has report published.
