New gene may drive earliest brain changes in Alzheimer’s

Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime. Read More

Noise-inducing neurons shut down memories in Alzheimer’s

In mouse models of Alzheimer's disease, active neurons still encode memory, and a group of active neurons encodes novel environmental information. The signal of the novelty containing neurons causes a superimposition disturbing the signal of memory encoding neurons. Read More

Repetitive negative thinking linked to dementia risk

Repetitive negative thinking (RNT) in those aged over 55 is associated with an increased risk of cognitive decline and deposition of proteins associated with Alzheimer's disease. People who exhibited higher levels of RNT experienced more cognitive and memory problems over four years. They were more likely to have both amyloid-beta and tau protein deposits throughout the brain. Read More

Early-life education improves memory in old age, especially for women

Females who attend school for longer have better memory ability in old age, a new study reports. For each year of education, memory gains were, on average, five times greater for women than the losses experienced due to each year of aging. Read More

New gut-brain link: How gut mucus could help treat brain disorders

Changes in gut mucus may contribute to Alzheimer's, Parkinson's, and other neurological disorders. Researchers noted changes in types of gut mucus bacteria in those with a range of neurological disorders compared to their healthy peers. Findings suggest those with reduced gut mucus protection may be more susceptible to gastrointestinal problems. Read More

Dementia gene raises risk of severe COVID-19

People with the Alzheimer's associated ApoE e4e4 gene have increased vulnerability to developing severe symptoms of COVID-19 if they become infected with the virus. Findings suggest those with the dementia-related gene have double the risk of developing severe coronavirus symptoms compared to those who those with the common e3e3 form of the APOE gene. Read More

3D brain-like tissue model links Alzheimer’s disease with herpes

A 3D human tissue culture model demonstrated a possible causal relationship between Alzheimer's disease and herpes simplex virus 1 (HSV-1) infection. 40 Alzheimer's associated genes were over-expressed in the HSV-1 infected brain tissue, including genes associated with the production of amyloid-beta.
