Study reveals roots of Parkinson’s in the brain

Changes in the brain's serotonin system may occur years before Parkinson's disease symptoms begin. Serotonin alterations could be used as a biomarker for Parkinson's disease.

Sleep history predicts late-life Alzheimer’s pathology

Your sleep history during middle age may predict Alzheimer's pathology later in life. A decrease in sleep quality between 50 and 70 years of age is associated with higher levels of tau and amyloid beta in the brain. Changes in brain activity and quality of sleep could be a biomarker for Alzheimer's disease.

Education and intelligence may protect cognition’ but don’t prevent Alzheimer’s disease

Intelligence, education and participating in cognitively challenging tasks may stave off the effects of dementia for longer, but can not protect against the inevitable Alzheimer's pathology in those at risk.

Antibiotic treatment alleviates Alzheimer’s disease symptoms in male mice

Study reports specific gut bacteria can influence the development of Alzheimer's disease. In mouse models, long term antibiotic treatment reduced inflammation and the formation of amyloid plaques. However, the reduction was only seen in males. Additionally, the antibiotic treatment altered the activation of microglia in the male mouse models.

When is Alzheimer’s not Alzheimer’s? Researchers characterize a different form of dementia

LATE, a form of dementia that appears in the oldest-old is often mistaken for Alzheimer's disease, but the brain pathology is very different. The protein TDP-43 appears to play a significant role in the development of LATE. The neurodegenerative disease may progress more gradually than Alzheimer's, but when combined with Alzheimer's disease (a common combination), appears to cause a more rapid decline than either would alone.
