What causes Alzheimer’s? Not toxic amyloid, new study suggests

Many researchers have argued that the accumulation of toxic beta-amyloid in the brain causes Alzheimer’s. However, a new study offers some evidence contradicting this sequence. Share on PinterestNew research is questioning the predominant hypothesis that a buildup of beta-amyloid causes Alzheimer’s disease. Alzheimer’s disease affects over 5.5 million people in the United States and millions […]

How two experimental Alzheimer’s drugs reverse aging

New research in mice reveals the mechanisms through which two experimental drugs that may treat Alzheimer’s disease have broader, anti-aging properties and can reverse age-related cognitive decline. Share on PinterestNew research explains how two experimental dementia drugs may reverse normal aging. Family history, genes, and some lifestyle choices all influence a person’s risk of Alzheimer’s […]

Transport breakdown in brain cells may lead to Alzheimer’s, Parkinson’s

After studying the process in mice and flies, scientists suggest that failure to transport the molecular machines that break down proteins in cells could lie at the heart of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Share on PinterestFaulty transportation mechanisms within nerve cells may lead to neurodegeneration in Alzheimer’s or Parkinson’s disease. The ability […]

Alzheimer’s risk gene and heavy metal exposure may impair cognition

A new study in mice finds that cadmium exposure, combined with a genetic predisposition to Alzheimer’s, can trigger symptoms of cognitive decline. Share on PinterestFor people with a key risk gene, exposure to cadmium may raise the risk of cognitive impairment, suggests new research in mice. The so-called human apolipoprotein E (APOE) gene encodes instructions […]
