Biologists report that they have discovered the first link between the amyloid plaques that form in the brains of Alzheimer's patients and a gene previously implicated in the aging process, SIRT1.
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.
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.
HIV-related memory loss linked to Alzheimer's protein More than half of HIV patients experience memory problems and other cognitive impairments as they age, and doctors know little about the underlying causes. New research suggests HIV-related cognitive deficits share a common link with Alzheimer's-related dementia: low levels of the protein amyloid beta in the spinal fluid.
