In the past, we have covered the evolving research on concussions and traumatic brain injury (TBI) in relation to dementia risk. For example, when <\/span>Aaron Hernandez<\/span><\/a> passed away at the age of 27, his brain provided researchers with some remarkable clues.<\/span><\/p>\n

Formally a professional NFL player, he had been suffering from the worst case of chronic encephalopathy ever seen in someone his age. This brain condition is associated with repeated blows to the head, resulting in an increased risk of dementia. <\/span><\/p>\n

We then covered the link between <\/span>contact sports and brain health<\/span><\/a>, as well as the <\/span>long-term effects of concussions<\/span><\/a>. More recently, a study on traumatic brain injury and dementia risk was published in the <\/span>Lancet Psychiatry<\/span><\/i>. Being the largest study of its kind, the true effects of traumatic brain injury are becoming much more apparent.<\/span><\/p>\n

New Study Offers <\/span>Evid<\/span>ence on the Dangers of Repeated Head Injuries<\/span><\/h1>\n

Those who experienced a mild brain injury increased their risk of 17 percent. The researchers also found that the risk of dementia increased 33 percent for two or three TBIs, 61 percent for four TBIs, and 183 percent for five or more TBIs. <\/span><\/p>\n

Another important finding was based on when someone has a brain injury. For those in their 20s, a brain injury can increase their risk of dementia in their 50s by 60 percent. <\/span><\/p>\n

Although these numbers are alarming, it is important to note that the majority of individuals who sustain a single concussion will not go on to develop dementia. On that note, the researchers did recommend that following a TBI, it is important to get an evaluation. <\/span><\/p>\n

BrainTest\u00ae<\/span><\/a> is a scientifically-validated app that can help individuals track their cognition across time. In turn, this tool helps detect early warning signs of dementia and mild cognitive impairment. Taken in the comfort of your home, it is a simple and effective way to increase awareness and overall peace-of-mind. <\/span><\/p>\n

Symptoms of TBI<\/h2>\n

Common in contact sports, when an individual suffers a blow to the head, a number of symptoms may follow. It is important to be aware of the following symptoms, as they may indicate that a brain injury has occurred.<\/span><\/p>\n

The largest and first of its kind, <\/span>this study<\/span><\/a> included data from 2.8 million people in Denmark. After examining 36 years of health records, it was found that even a single severe brain injury can increase the risk of dementia later in life. In fact, one\u2019s risk increased to 35 percent in comparison to someone who had never experienced brain trauma. <\/span><\/p>\n
