Background: Alzheimer's disease (AD) develops undetected for years due to the lack of early diagnostic biomarkers. In advanced AD, visual deficits related to cortical neurodegeneration are well recognized, but recent studies have identified that the retina could be affected prior to vulnerable brain...
In Alzheimer's disease, clumps of amyloid form plaques around the neurons of thebrain, while another protein, tau, accumulates inside the nerve cells in what are referred to as tangles. Plaque and tangles appear first in one region of the brain and then spread, causing gradually deteriorating f...
Alzheimer’s disease is often seen as a late-life disease, but this study shows that early-life factors may play a significant role in developing the neurodegenerative disease, Shapiro said. She and her fellow researchers in the LEAD Center, a research and training center at the Colorado School...
Louis found that older people who have less slow-wave sleep, the deep sleep one needs to consolidate memories and wake up feeling refreshed, have higher levels of the brain protein tau, and elevated tau is a sign of Alzheimer's disease and has been linked to brain damage and cognitive ...

Purpose: Many patients with early symptoms of Alzheimer's disease (AD) first seek help from their primary care providers (PCPs). PCPs must therefore be watchful for signs and symptoms of AD, and should screen elderly patients who complain of memory and cognitive problems for dementia.Data source...
Alzheimer's consistently overestimated the turns on the route and showed increased variability in their sense of direction. However, these specific impairments were not observed in the healthy older participants or people withmild cognitive impairment, who did not show underlying signs of Alzheimer's....
Both beta amyloid plaques and tau tangles are early signs of the brain’s march toward a possible Alzheimer’s disease diagnosis. Amyloid plaques typically appear first, with tau tangles arriving later as the disease progresses. Related article Mediterranean diet linked with...
This is the hallmark of Alzheimer's disease. Initially, only shortterm memory is impaired, and the person merely seems forgetful. But because short-term memory is essential for absorbing new information, the impairment soon interferes with the ability to interact socially and perform one's work....
