Risk Factors For Alzheimer's Disease.
Older adults with respect problems and a portrayal of concussion have more buildup of Alzheimer's disease-associated plaques in the brain than those who also had concussions but don't have remembrance problems, according to a new study. "What we think it suggests is, head trauma is associated with Alzheimer's-type dementia - it's a danger factor," said study researcher Michelle Mielke, an affiliated professor of epidemiology and neurology at Mayo Clinic Rochester. But it doesn't far-out someone with head trauma is automatically going to develop Alzheimer's immunity law definition. Her look is published online Dec 26, 2013 and in the Jan 7, 2014 print event of the journal Neurology.
Previous studies looking at whether head trauma is a risk factor for Alzheimer's have come up with conflicting results. And Mielke stressed that she has found only a vinculum or association, not a cause-and-effect relationship scriptovore. In the study, Mielke and her side evaluated 448 residents of Olmsted County, Minn, who had no signs of retention problems.
They also evaluated another 141 residents with memory and thinking problems known as mild cognitive impairment. More than 5 million Americans have Alzheimer's disease, according to the Alzheimer's Association. Plaques are deposits of a protein sherd known as beta-amyloid that can found up in between the brain's nerve cells. While most mobile vulgus develop some with age, those who develop Alzheimer's generally get many more, according to the Alzheimer's Association.
They also be biased to get them in a predictable pattern, starting in brain areas crucial for memory. In the Mayo study, all participants were old 70 or older. The participants reported if they ever had a brain injury that snarled loss of consciousness or memory. Of the 448 without any memory problems, 17 percent had reported a sense injury. Of the 141 with memory problems, 18 percent did.
