Risk Factors For Alzheimer's Disease.
Older adults with recall problems and a recapitulation of concussion have more buildup of Alzheimer's disease-associated plaques in the intelligence than those who also had concussions but don't have respect problems, according to a new study. "What we think it suggests is, guide trauma is associated with Alzheimer's-type dementia - it's a gamble factor," said study researcher Michelle Mielke, an secondary professor of epidemiology and neurology at Mayo Clinic Rochester. But it doesn't refer to someone with head trauma is automatically contemporary to develop Alzheimer's resources. Her ponder is published online Dec 26, 2013 and in the Jan 7, 2014 put out issue of the journal Neurology.
Previous studies looking at whether prime trauma is a risk factor for Alzheimer's have come up with conflicting results. And Mielke stressed that she has found only a tie or association, not a cause-and-effect relationship. In the study, Mielke and her duo evaluated 448 residents of Olmsted County, Minn, who had no signs of thought problems.
They also evaluated another 141 residents with reminiscence and thinking problems known as yielding cognitive impairment. More than 5 million Americans have Alzheimer's disease, according to the Alzheimer's Association. Plaques are deposits of a protein particle known as beta-amyloid that can shape up in between the brain's gumption cells. While most people develop some with age, those who exhibit Alzheimer's generally get many more, according to the Alzheimer's Association.
They also take care of to get them in a predictable pattern, starting in brain areas crucial for memory. In the Mayo study, all participants were elderly 70 or older. The participants reported if they ever had a perception injury that confused loss of consciousness or memory. Of the 448 without any memory problems, 17 percent had reported a brains injury. Of the 141 with celebration problems, 18 percent did.
