1. Oxygen Treatment Hastens Memory Loss In Alzheimer's Mice
   Researchers suspect the culprit precipitating Alzheimer's disease in some elderly patients may be high concentrations of oxygen administered during or after major surgery -- a hypothesis borne out in a recent animal model study.
2. Infections May Lead To Faster Memory Loss In Alzheimer's Disease
   Getting a cold, stomach bug or other infection may lead to increased memory loss in people with Alzheimer's disease, according to new research.
3. Sleep Loss Linked To Increase In Alzheimer's Plaques
   Chronic sleep deprivation in a mouse model of Alzheimer's disease makes Alzheimer's brain plaques appear earlier and more often, researchers report. They also found that orexin, a protein that helps regulate the sleep cycle, appears to be directly involved in the increase.
4. Declines In Other Thinking And Learning Skills May Precede Memory Loss In Alzheimer's Disease
   Cognitive abilities other than memory, including visuospatial skills needed to perceive relationships between objects, may decline years prior to a clinical diagnosis in patients with Alzheimer's disease, according to a new report.
5. Does Diabetes Speed Up Memory Loss In Alzheimer's Disease?
   Research has shown that diabetes increases the risk of Alzheimer's disease and the risk of memory loss in people who don't have Alzheimer's disease. But it hasn't been clear whether people with Alzheimer's disease and diabetes have more rapid memory loss than those who have Alzheimer's disease but no diabetes.
