(Medical Xpress)—Scientists' picture of how a gene strongly linked to Alzheimer's disease harms the brain may have to be revised, researchers at Washington University School of Medicine in St. Louis have found. http://medicalxpress.com/news/2013-05-perspective-role-major-alzheimer-gene.html Medical research Tue, 07 May 2013 07:32:39 EST news287130751 Close family members of people with Alzheimer's disease are more than twice as likely as those without a family history to develop silent buildup of brain plaques associated with Alzheimer's disease, according to researchers at Duke Medicine. http://medicalxpress.com/news/2013-04-family-history-alzheimer-abnormal-brain.html Alzheimer's disease & dementia Wed, 17 Apr 2013 17:00:01 EST news285423778 Researchers have identified a possible treatment window of several years for plaques in the brain that are thought to cause memory loss in diseases such as Alzheimer's.

The study is published in the October 16, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology. http://medicalxpress.com/news/2012-10-plaque-build-up-brain-alzheimer-gene.html Neuroscience Mon, 15 Oct 2012 16:00:11 EST news269513181 Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer's disease, but the gene's role in the disease has been unclear. Now, researchers funded by the National Institutes of Health have found that in mice, having the most risky variant of ApoE damages the blood vessels that feed the brain. http://medicalxpress.com/news/2012-05-apoe4-alzheimer-gene-brain-blood.html Alzheimer's disease & dementia Wed, 16 May 2012 13:00:01 EST news256391662 The available evidence is insufficient to draw firm conclusions about the association of modifiable factors and risk of Alzheimer's disease (AD), according to a report posted online today that will appear in the September issue of Archives of Neurology. http://medicalxpress.com/news/2011-05-evidence-insufficient-relationship-factors-alzheimer.html Alzheimer's disease & dementia Mon, 09 May 2011 16:33:12 EST news224177519
