Brain Thinning Predicts Alzheimer’s 10 Years Before Symptoms

Researchers identified cortical gray matter thinning as a potential early biomarker for dementia. In a study involving 1,500 participants from diverse backgrounds, thinner cortical gray matter was linked to a higher risk of developing dementia 5 to 10 years before symptoms appeared.

Disconnect Between Dopamine System and Cocaine Addiction Uncovered

Researchers report the release of dopamine alters when working to obtain cocaine. The study reports, the more effort it takes to secure a supply of the illicit drug, the lower the release of dopamine when taking cocaine.

Excessive Sleep May Hurt Cognitive Function

Sleeping more than nine hours a night may be detrimental to brain health, particularly for individuals experiencing symptoms of depression, according to a new study. Researchers analyzed data from nearly 2,000 dementia-free adults and found that long sleep duration was associated with worse performance in memory, visuospatial ability, and executive function.

Gene Defect Linked Brain Size and Social Behavior in ASD, Schizophrenia

A new study reveals how genetic deficits, particularly in the Tbx1 gene, are linked to reduced brain volume and altered social behavior, findings relevant to autism and schizophrenia. Researchers observed smaller amygdala volumes in Tbx1-deficient mice, a brain region key to emotional regulation and social behavior. These mice displayed less interest in social interaction, relying more on non-social cues like bedding preferences.

Midlife Cortisol Levels Linked to Alzheimer’s Risk

A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause.

Novel Root Cause of Tau-Induced Neurodegeneration Discovered

mRNA decay may facilitate tau-induced damage to the brain and associated apoptosis that contributes to a range of neurodegenerative disorders. Researchers found the mechanism can be altered pharmacologically, providing a new target for the development of therapeutics to prevent or slow the progression of some neurodegenerative disorders.
