Truamatic brain injury raise the risk of dementia in adults who are 55 years old. This head injury could cause more hazards for aged people as compared to the young ones.

Traumatic brain injury is also known as concussion. It is one of the most common injuries of brain which usually occur due to the sports and other recreation activities.

A moderate to severe TBI is associated with an increase in dementia risk for adults 55 years of age and older, they report. But, for senior citizens – age 65 and older – it only takes a mild TBI to make dementia look more likely.

Experts of University of California conducted this study. They analyzed the data of 164,661 people to confirm this research.  Most of these people faced TBI or non-TBI body trauma of neck and head.

The result demonstrates that nearly 32 percent of patient sufferd from dementia after TBI. This 32 percent is equivalent to 51,799 patinets of Traumatic brain injury. However, the average time for the emergence of trauma is the first 3.2 years after the TBI injury.

Dr. Raquel Garner, main author of the study stated that it is indeed really astonishing that aged brain are more open to the after effects of the traumatic brian injury. Therefore, people should make an effort to avoid the head injuries specially in adults.
