Research into Alzheimer’s disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients’ brain tissue, a pathological form of the tau protein contributes to propagating the disease in the brain. In new research from their joint laboratory, Judith Steen, Ph.D., and Hanno Steen, Ph.D. show for the […]

A new study by Monash University has found that obstructive sleep apnea (OSA) has been linked to an increased risk of dementia. The study, published in the Journal of Alzheimer’s Disease, and led by Dr Melinda Jackson from the Turner Institute for Brain and Mental Health, found that severe OSA is linked to an increase in a protein, called beta-amyloid, […]

WEDNESDAY, Oct. 14, 2020 — A procedure to restore normal heart rhythm is more effective than medications in reducing dementia risk in people with the heart rhythm disorder atrial fibrillation (AF), researchers report. Previous studies have shown that AF is associated with an increased risk of dementia. This one assessed whether catheter ablation and medications for AF reduced that risk. […]

A new study indicates that the brain goes through a “cleansing” process while you sleep. Experts say this cleansing washes away proteins that accumulate during the day and can help lower the risk of dementia. Experts say there are a number of tips for getting better sleep, ranging from a consistent wake-up time to how you style your bedroom. Sleep […]

Modifying 12 risk factors over the lifecourse could delay or prevent 40% of dementia cases, according to an update to The Lancet Commission on dementia prevention, intervention, and care, which is being presented at the Alzheimer’s Association International Conference (AAIC 2020). Combined, the three new risk factors are associated with 6% of all dementia cases—with an estimated 3% of cases […]

Dementia is the name given to a group of symptoms linked to an ongoing decline in brain function. You could lower your risk of the neurodegenerative condition by regularly eating berries, it’s been revealed. There are a number of different types of dementia, and the most common in the UK is Alzheimer’s disease. Diagnosing the condition early could help to […]

Whether elevated blood pressure early in life translates to increased risk of dementia is a question scientists are working to answer. “Dementia is not a normal part of aging, and once it begins you can’t reverse it,” says Dr. Shaoyong Su, genetic epidemiologist at the Georgia Prevention Institute at the Medical College of Georgia at Augusta University. “It typically surfaces […]

Fresh insights into damaging proteins that build up in the brains of people with Alzheimer’s disease could aid the quest for treatments. A study in mice reveals how the two proteins work together to disrupt communication between brain cells. Scientists observed how proteins—called amyloid beta and tau—team up to hamper key genes responsible for brain messaging. By changing how genes […]

(HealthDay)—Could your personality as a teen forecast your risk for dementia a half-century later? Very possibly, say researchers, who found that dementia risk is lower among seniors who were calm, mature and energetic high schoolers. “Being calm and mature as teen were each associated with roughly a 10% reduction in adult dementia risk,” said study co-author Kelly Peters, principal researcher […]

For the first time, it has been shown that deficits of semantic memory, an ability we use to recognize objects and use them correctly, are involved in specific eating disorders shared by patients suffering from dementia. This is suggested by a study conducted by the Laboratory of Professor Raffaella Rumiati of SISSA in Trieste just published in the Journal of […]
