- Discovery of new role for the brain’s immune cells could have Alzheimer's implicationson October 15, 2021 at 1:48 pm
The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain's small vessels.

- In neurodegenerative diseases, brain immune cells have a 'ravenous appetite' for sugaron October 13, 2021 at 7:21 pm
At the beginning of neurodegenerative disease, the immune cells of the brain -- the 'microglia' -- take up glucose, a sugar molecule, to a much greater extent than hitherto assumed. These results are of great significance for the interpretation of brain scans depicting the distribution of glucose in the brain. Furthermore, such image-based data could potentially serve as a biomarker to non-invasively capture the response of microglia to therapeutic interventions in people with dementia.
- Personality traits linked to hallmarks of Alzheimer’s diseaseon October 12, 2021 at 10:57 pm
New research found that changes in the brain associated with Alzheimer's disease are often visible early on in individuals with personality traits associated with the condition. The study focused on two traits previously linked to the risk of dementia: neuroticism, which measures a predisposition for negative emotions, and conscientiousness, which measures the tendency to be careful, organized, goal-directed and responsible.
