A study in Nature Aging identified that age-related reduction of a specific brain protein may contribute to neuronal dysfunction in Alzheimer's disease. The research examines protein-mediated mechanisms in the brain's clearance system relevant to memory loss and cognitive decline.
Research demonstrates that using personalized fMRI resting-state scans to target transcranial magnetic stimulation (TMS) increases depression response rates to 80%, compared to 60% with standard scalp-based targeting. The accelerated protocol offers potential faster treatment timelines (one week) for patients with treatment-resistant depression.
Research indicates that average daytime light exposure above 1,000 lux is associated with a 16% reduction in dementia risk. Getting less than 42 minutes of bright daily light exposure was found to be a stronger predictor of dementia than six conventional clinical risk factors.
Research demonstrates that systemic bodily inflammation alters brain function and can trigger depression-like symptoms and sickness behavior, particularly during acute infections and chronic autoimmune conditions. The study explores the biological mechanisms linking peripheral inflammation to central nervous system effects.
CADASIL is a hereditary condition affecting small blood vessels in the brain, causing recurrent strokes and progressive cognitive decline leading to early-onset dementia. Researchers are using zebrafish as a model organism to better understand the disease mechanisms and develop potential treatments.
