Study Links Muscle Loss to Alzheimer’s Risk

New research shows that skeletal muscle loss, measured through temporalis muscle size on brain MRIs, is associated with a higher risk of developing Alzheimer’s disease. A study of 621 older adults found that those with smaller temporalis muscles were 60% more likely to develop dementia and experienced greater cognitive and brain volume decline over nearly six years.

Visceral Fat May Indicate Alzheimer’s Risk Decades Before Symptoms

A new study links visceral fat, a deep layer of abdominal fat, to increased brain amyloid and tau proteins—key markers of Alzheimer’s disease—decades before dementia symptoms arise. Researchers found that visceral fat accounted for 77% of the relationship between high BMI and amyloid accumulation, while other fat types showed no similar impact. The study highlights how managing visceral fat through lifestyle changes or medication could reduce Alzheimer's risk.

Concussion Impacts Brain Activity and Cognition in High Schoolers

Concussions affect aperiodic brain activity, a key signal often dismissed as "background noise," which plays a role in brain excitability and cognitive function. High school football players who experienced concussions showed slowed aperiodic activity, correlating with worse memory, concentration, and post-concussion test scores.

AI Reveals Brain Differences in ADHD

Researchers utilizing artificial intelligence (AI) to analyze brain MRI scans have identified significant differences in white matter tracts of adolescents with ADHD. The study, involving over 1,700 participants from the multi-institutional Adolescent Brain Cognitive Development Study, used diffusion-weighted imaging (DWI) and a deep-learning AI model to detect these variations.

New Treatment for COVID-Induced Smell Loss

A new study presents a promising treatment for restoring the sense of smell in long-COVID patients. The study explores the effectiveness of CT-guided stellate ganglion block, a minimally invasive procedure, in treating parosmia—a condition affecting up to 60% of COVID-19 patients where the sense of smell is distorted.

Long COVID’s Unique Neural Impact

A new study reveals distinct brain changes in long COVID patients compared to those fully recovered from COVID-19 and healthy controls. The research employed Diffusion Microstructure Imaging (DMI) to analyze brain microstructures in 89 long COVID patients, 38 recovered COVID-19 patients, and 46 healthy individuals.

Midlife Visceral Fat Tied to Alzheimer’s Risk

Researchers reveal that higher amounts of visceral abdominal fat in midlife is associated with the development of Alzheimer's disease. Visceral fat, the fat surrounding internal organs, is linked to brain changes up to 15 years before Alzheimer's symptoms appear.
