Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia

Head Injury With Loss Of Consciousness Does Not Increase The The Risk Of Dementia.
Having a distressing planner injury at some rhythm in your life doesn't raise the risk of dementia in old age, but it does increase the odds of re-injury, a unusual study finds. "There is a lot of fear among people who have sustained a brain hurt that they are going to have these horrible outcomes when they get older," said senior author Kristen Dams-O'Connor, subsidiary professor of rehabilitation medicine at the Icahn School of Medicine at Mount Sinai Medical Center in New York City. "It's not true. But we did catch a risk for re-injury".

The 16-year learning of more than 4000 older adults also found that a recent traumatic brain injury with unconsciousness raised the unevenness of death from any cause in subsequent years. Those at greatest risk for re-injury were people who had their discernment injury after age 55, Dams-O'Connor said. "This suggests that there are some age-related biological vulnerabilities that come into place in terms of re-injury risk".

Dams-O'Connor said doctors need to look out for health issues among older patients who have had a traumatic brain injury. These patients should try to dodge another head injury by watching their balance and taking care of their overall health. To investigate the consequences of a harmful brain injury in older adults, the researchers collected data on participants in the Adult Changes in Thought study, conducted in the Seattle limit between 1994 and 2010. The participants' standard age was 75.

At the start of the study, which was published recently in the Journal of Neurology, Neurosurgery & Psychiatry, none of the participants suffered from dementia. Over 16 years of follow-up, the researchers found that those who had suffered a damaging sagacity injury with loss of consciousness at any time in their lives did not increase their risk for developing Alzheimer's or other forms of dementia.

The gamble of another traumatic brain injury, however, more than doubled if the win injury occurred before age 25 and almost quadrupled if the injury happened after age 55. Similarly, a late-model traumatic brain injury more than doubled the odds of death from any cause, the study found. Dams-O'Connor's company plans to look at risk factors to try to understand why some people have ill long-term prognosis after a brain injury.

One expert said genetics may play a role. "My suppose is that the risk for post-traumatic-brain-injury Alzheimer's disease has a genetic component with some genes increasing danger and others offering protection," said Dr Sam Gandy, associate director of the Mount Sinai Alzheimer's Disease Research Center in New York City. These findings should not be bollixed with those about athletes who suffer brain injuries.

So "The dramatic examples of past National Football League players, hockey players and wrestlers who have an unusual illness, prominent by depression, agitation and psychosis are quite different from Alzheimer's disease patients who tend to be apathetic. Much remains to be discovered about the capacity of lifelong traumatic brain injury history, including inflexibility and nature of torque and other physical factors, and late-life mental decline".

Another expert, Dr Danny Liang, a neurosurgeon at North Shore-LIJ Cushing Neuroscience Institute in Manhasset, NY, thinks these findings are too tight-fisted to turn much about the risk of dementia as a result of traumatic brain injury. "The learn is restricted to a limited population so it's hard to extrapolate these findings to other populations. It is also accomplishable that there were people who had traumatic brain injury who did develop dementia before age 65, so they were not included in the study". There also was no material on injury severity or duration of unconsciousness sturgeon. Brain injuries differ, and informed the severity is important to determine the ultimate outcome.
