July 3, 2026 Using alcohol to cope with stress when young may permanently alter the brain, making it harder to adapt to challenges and increasing the risk of returning to drinking later in life. Researchers also found signs of brain damage associated with early ...
July 3, 2026 Some brains appear to fight back against Alzheimer's by helping immature brain cells survive damage instead of succumbing to it. Understanding this natural resilience could point researchers toward entirely new ways to protect memory and slow ...
July 3, 2026 Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged and damaged blood vessels deep within the brain. ...
July 1, 2026 A surprising discovery is overturning a long-held assumption about how the brain’s movement center works. Researchers found that two key cerebellar cell types—thought to be tightly linked—often ...
July 1, 2026 Could something as simple as vitamin C help support a healthier aging brain? In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and ...
June 30, 2026 A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe ...
