This conclusion comes from a natural experiment in Wales, where vaccine eligibility was determined by birthdate.Read More
FeaturedNeurologyNeuroscience·March 25, 2025·6 min readADHD May Raise Dementia RiskA new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs of nerve damage in ADHD patients compared to healthy individuals.Read More

While ischemic strokes caused by blood clots have long been linked to cognitive decline, this study shows that hemorrhages also significantly increase dementia risk. Using Medicare data from nearly 15,000 patients, scientists observed a two-fold increase in dementia diagnosis within about 5.6 years after a brain bleed.Read More

Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.Read More

Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.Read More
