March 16, 2009 WASHINGTON - You've heard that diabetes hurts your heart, your eyes, your kidneys. New research indicates a more ominous link: That diabetes increases the risk of getting Alzheimer's disease and may speed dementia once it strikes.
More Evidence That Intelligence Is Largely Inherited: Researchers Find That Genes Determine Brain's Processing Speed A new type of brain imaging scanner shows that intelligence is strongly influenced by the quality of the brain's axons or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.
Diabetes And Elevated Levels Of Cholesterol Linked To Faster Cognitive Decline In Alzheimer's Patients A history of diabetes and elevated levels of cholesterol, especially LDL cholesterol, are associated with faster cognitive decline in patients with Alzheimer's disease, according to a new study. These results add further evidence of the role of vascular risk factors in the onset and progression of Alzheimer's disease.
Young Adults At Future Risk Of Alzheimer's Have Different Brain Activity, Says Study Young adults with a genetic variant that raises their risk of developing Alzheimer's disease show changes in their brain activity decades before any symptoms might arise, according to a new brain imaging study by scientists. The results may support the idea that the brain's memory function may gradually wear itself out in those who go on to develop Alzheimer's.
Many can cope with news of higher Alzheimer's risk July 15, 2009 ATLANTA - People who learn through genetic testing that they have a higher than average risk for Alzheimer's disease are able to handle the bad news pretty well, results from the first major study of this suggest.
