Head injuries may worsen cognitive decline says Study:- All those who experience head injuries during their 50s or at a younger age will have a decline in the cognitive tests at the age of 70 told a new study. The study told that the head injuries will not appear to the contribution of the brain damage characteristic of Alzheimer's disease and will lead to dementia symptoms. Sarah-Naomi James, the lead researcher of University College London (UCL) said that they found strong evidence the head injuries will have an impact on the brain health and the thinking skills once the age turns more. The aging process also depends on the head injuries that took place in the past. The study is published in the journal Annals of Clinical and Translational Neurology.

The research team collected the feedback from the 502 participants. Most of them are asked if they got knocked unconscious at the age of 53. 21 percent of the people who participated in the survey said yes. Some of the people who are at the age of 70 underwent brain scans and they took cognitive tests. All those who had head injuries years ago performed worse than expected in the tests. They even had brain volumes by 1 percent. Their microstructural integrity in the brain was different for those who were injured in the past. There were no differences in the amyloid protein or any signs of Alzheimer-related disease. The study said that the head injury would cause dementia or its symptoms.
