Patients whose symptoms begin on the right side tend to experience greater cognitive decline and higher dementia risk.Read More

Scientists found that neurons in both flies and human models of tauopathy accumulate excess glycogen, which disrupts cellular stress management when it can’t be broken down.Read More

The study found that axonal boutons—sites where neurons form connections—had reduced turnover in Alzheimer’s mice, indicating impaired brain plasticity. After a single rTMS session, the turnover of one bouton type significantly increased, matching levels seen in healthy mice.Read More

A new study identifies a specific gene, ATPPIF1, that is reactivated through exercise and supports neuroplasticity in the brain.Read More

Scientists found structural abnormalities in the paranode region, where myelin attaches to axons, including clogged nutrient channels and protein buildup that could block signal transmission.Read More
