Immune cells found in the brain are behind the depression experienced in inflammation
January 25, 2021
Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. This is the conclusion of a study using mice. The results suggest that microglial cells contribute to the negative mood experienced during se...

First observation of the early link between proteins linked to Alzheimer’s disease
January 25, 2021
Researchers demonstrate, for the first time in humans, how the first deposits of tau proteins in the brainstem are associated with neurophysiological processes specific to the early stages of Alzheimer's disease development.
Abnormal hyperactivation in the brain may be an early sign of Alzheimer’s
January 21, 2021
A psychology and neuroscience professor has just targeted an early biomarker of the disease.
Deep sleep takes out the trash
January 20, 2021
By examining fruit flies' brain activity and behavior, the researchers found that deep sleep has an ancient, restorative power to clear waste from the brain. This waste potentially includes toxic proteins that may lead to neurodegenerative disease.
NAD+ can restore age-related muscle deterioration, research finds
January 19, 2021
Scientists have discovered that Alzheimer's-like protein aggregates underly the muscle deterioration seen in aging. But the aggregates can be reversed by boosting the levels of nicotinamide adenine dinucleotide (NAD+), which turns on the defense systems of mitochondria in cells and restores muscle f...

Eye tests predict Parkinson’s-linked cognitive decline 18 months ahead
January 19, 2021
Simple vision tests can predict which people with Parkinson's disease will develop cognitive impairment and possible dementia 18 months later, according to a new study. In a related study, the researchers also found that structural and functional connections of brain regions become decoupled through...

Memory may be preserved in condition with brain changes similar to Alzheimer’s disease
January 13, 2021
Primary progressive aphasia is a rare neurodegenerative condition characterized by prominent language problems that worsen over time. About 40% of people with the condition have underlying Alzheimer's disease. But a new study has found that people with the condition may not develop the memory proble...

MIND and Mediterranean diets associated with later onset of Parkinson’s disease
January 13, 2021
A new study suggests a strong correlation between following the MIND and Mediterranean diets and later onset of Parkinson's disease (PD). While researchers have long known of neuroprotective effects of the MIND diet for diseases like Alzheimer's and dementia, this study is the first to suggest a lin...

Approximately half of AD dementia cases are mild, one-fifth are severe
January 13, 2021
What percent of patients with Alzheimer's Disease (AD) currently have severe dementia? Do more people have mild disease? Or are the majority suffering with moderate dementia? A new study using data from the Framingham Heart Study (FHS) sheds light on these trends....

New studies support blood test for early detection of Alzheimer’s disease
January 13, 2021
Researchers provide convincing evidence that an in-house developed blood test for Alzheimer's disease can detect the disease early and track its course, which has major implications for a potential use in clinical practice and treatment trials.
