Although concussions have been acknowledged in the media and research as having great risks and increase the potential to develop dementia, new research suggests that even small, seemingly insignificant hits to the head can increase one’s risk of dementia. In the United States 357, 558 veterans were tracked for approximately four years. About half of these participants had been diagnosed with a traumatic brain injury and about 54 percent had experienced a concussion within their life. Participants who experienced a concussion were broken into three groups: those who did not lose consciousness but were woozy for a day, those who lost consciousness for less than 30 minutes, and those who lost consciousness for more than 30 minutes. Researchers found that those who did not lose consciousness were twice as likely to develop dementia than those who did not experience a concussion. Those who lost consciousness were three to four times more likely to experience dementia and memory loss respectively and in direct proportion to the severity of their injury. With this in mind, a call for better protocol and protection for those in high contact sports, such as football, and combatants is in order.
