Scientists map toxic proteins linked to Alzheimer’s

A team of researchers from McMaster University has mapped at atomic resolution a toxic protein linked to Alzheimer’s disease, allowing them to better understand what is happening deep within the brain during the earliest stages of the disease. The findings, published on the front cover of the current edition of…

Sleep history predicts late-life Alzheimer’s pathology: Findings suggest novel, sleep-based diagnosis and treatment methods

Sleep patterns can predict the accumulation of Alzheimer’s pathology proteins later in life, according to a new study of older men and women published in JNeurosci. These findings could lead to new sleep-based early diagnosis and prevention measures in the treatment of Alzheimer’s disease. Alzheimer’s disease is associated with disrupted…

Astrocytes protect neurons from toxic buildup

Astrocytes are overtaxed neurons’ pit crew. The brain cells collect damaged lipids secreted by hyperactive neurons, then recycle those toxic molecules into energy, researchers at the Howard Hughes Medical Institute’s Janelia Research Campus report May 23, 2019, in the journal Cell. It’s a mechanism to protect neurons from the damaging…

Older adults expect to lose brain power, but most don’t ask doctors how to prevent dementia: Many in their 50s and early 60s buy supplements or do puzzles in hopes of protecting brain health, but may miss out on effective strategies

Many Americans in their 50s and early 60s are worried about declining brain health, especially if they have loved ones with memory loss and dementia, a new national poll finds. But while the majority of those polled say they take supplements or do puzzles in an effort to stave off…
