Imaging Technique Identifies Plaques And Tangles In Brains Of Severely Depressed Older Adults

Depression is one of the most common mental disorders in the elderly, but little is known about the underlying biology of its development in older adults. In a small study published in the November issue of the peer-reviewed journal Archives of General Psychiatry, UCLA researchers used a unique brain scan to assess the levels of […]

A Step Toward Unraveling Alzheimer’s Disease Is Described

Scientists outline new methods for better understanding links between specific proteins and the risks associated with Alzheimer’s disease in an article co-authored by University of Alabama researchers and publishing today in Science Express. In experiments using a series of model organisms, including yeast, microscopic roundworms and rats, the researchers show how basic mechanisms inside cells are […]

Brain Imaging Suggests That Falls May Be An Early Sign Of Alzheimer’s Disease

Falls and balance problems may be early indicators of Alzheimer’s disease, researchers at Washington University School of Medicine in St. Louis report July 17, 2011, at the Alzheimer’s Association International Conference on Alzheimer’s Disease in Paris. Scientists found that study participants with brain changes suggestive of early Alzheimer’s disease were more likely to fall than […]

Single Traumatic Brain Injury May Prompt Long-Term Neurodegeneration

Years after a single traumatic brain injury (TBI), survivors still show changes in their brains. In a new study, researchers from the Perelman School of Medicine at the University of Pennsylvania suggest that Alzheimer’s disease-like neurodegeneration may be initiated or accelerated following a single traumatic brain injury, even in young adults. The study appears online […]

Brain Scan Identifies Patterns Of Plaques And Tangles In Adults With Down Syndrome

In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer’s disease — in adults with Down syndrome. Published in the June edition of the Archives of Neurology, the finding may offer an additional clinical tool […]
