AD Learning And Memory Loss Problems Mimic Jet Lag

Findings from a recent study published in the Journal of Alzheimer’s Disease revealed that chemical alterations in brain cells triggered by disruptions in the body’s day-night cycle may be an underlying cause of the memory and learning loss observed in Alzheimer’s disease (AD). The study, conducted by University of California researchers,…

Donepezil Could Delay Alzheimer’s Patients Move into Nursing Home

U.K. researchers, headed by the Institute of Psychiatry, King’s College London, have found that donepezil administered during the later stages of Alzheimer’s might temporarily decrease the likelihood that someone will need to move into a nursing home. The study report, entitled “Nursing home placement in the Donepezil and…

Alzheimer’s May Progress Through Spread of a Brain Tau Protein

Scientists at Massachusetts General Hospital (MGH) have published a new study describing how neurofibrillary tangles — one of the hallmarks of Alzheimer’s disease — develop. Alzheimer’s disease is characterized by a progressive degeneration of specific brain regions, starting with those areas involved in memory. Two proteins are found at…

Improving Sleep in Mouse Models of Alzheimer’s Enhances Memory Performance

In a new study entitled “Rescue of long-range circuit dysfunction in Alzheimer’s disease models,” researchers discovered why Alzheimer’s disease patients experience sleep disturbances and discovered potential therapeutics to counteract this effect. The team observed that improving sleep in mouse models of Alzheimer’s disease also benefits their memory performance. The…

Early Alzheimer’s Biomarker May Exist in Young at High Genetic Risk of Disease

A research team attempting to identify new biomarkers of Alzheimer’s disease has found that young subjects at high genetic risk of Alzheimer’s development — while moving through a virtual maze — showed lower brain cell activity involved in spatial navigation than a control group, revealing differences in the brain decades before possible disease onset. The…
