Even mild brain injuries increase the risk of dementia

You don’t have Be a professional football player to get a tough cone in the head. According to one estimate by medical researchers, 22 More than 27 million people Every year around the world suffers a traumatic brain injury. Something has come up Car accidentFrom others Fall, Or Accepting a title On the football field. But the growing body of evidence suggests that even a minor head injury can cause long-term damage and increase the risk of neurological disease.

The brain is soft and is usually clogged from our skull by cerebrospinal fluid. But when something hits the head hard, our brain shakes and can break into those hard bones, resulting in swelling or bleeding. This can lead to exciting symptoms such as short-term memory loss or confusion. (People do not feel black or nauseous or restless as a result of every discussion))

A New research Published in the journal this month Alzheimer’s and dementia Tracking Americans is drawn from a large data pool whose health outcomes have been prolonged for the past 25 years. The authors see that head injuries, even mild ones, are associated with a long-term increase in the risk of dementia. Studies have also shown that the more people hold their heads around their necks, the higher the risk of developing dementia.

Dementia is a common term for cognitive impairment as a result of changes in memory and the brain. The most common type is Alzheimer’s disease, a progressive and irreversible disorder where neutrons interact with each other to cause protein disruption rupt but other types of dementia, including vascular dementia, which do not have enough blood flow to supply oxygen to the brain Dementia, which occurs due to cell degeneration in the frontal and lateral regions of the brain, can cause major changes in personality and behavior.

The researchers hope that this new information will add to the growing awareness of the effects of head injuries and the importance of prevention. Andrea Snyder, a neurologist at the University of Pennsylvania and lead author of the study, said: “This is one of the most important messages in this study’s household, because head injuries are somewhat preventable.”

Previous research Showed a similar relationship between head injury and dementia, but especially concentrated population. Military veterans. Snyder said the study was one of a look at the relationship between the general, community-based population, which could be more representative of the person who developed it.

Snyder and colleagues at the University of Pennsylvania have been pursuing people aged 45 to 655 in Minnesota, Maryland, North Carolina and Mississippi since the 19th study, with more than 14,000 participants participating in community research on atherosclerosis. The study was aimed at monitoring environmental and genetic conditions that may contribute to heart disease, but the researchers also collected medical records and asked participants to self-report any head injuries.

When researchers at the University of Pennsylvania analyzed data on traumatic brain injury, they found that people who suffered a head injury were 25 percent more likely to develop dementia. For those who suffered two or more head injuries, the risk was doubled.

Other health issues may also play a role. Genetics To do Some people The risk of recurrence is high; Some forms are associated with other progressive disorders such as hereditary or Parkinson’s and Huntington’s disease. Other risks include such vascular problems Diabetes And High blood pressure, Environmental effects such as pollution, And lifestyle choices like smoking. But Snyder says head injuries are a significant issue. “We were able to say that about 9.5 percent of our studies related to dementia were responsible for the cause of the head injury,” he said.
