by Kerry Sheridan MIAMI, United States (AFP) — As we age, our brain shrinks, but a select group of elders known as “super-agers” lose less brain volume than regular seniors, which may help them stay sharp, researchers said Tuesday. The findings in the Journal of the American Medical Association show that super-agers, 80 and older, have a significantly thicker brain cortex than people who are aging normally. The cortex is the largest part of the […]
MIAMI, United States (AFP) — A common gene variant has been discovered in about one-third of the population that may explain why some people’s brains age faster than others, United States researchers said Wednesday. The gene, known as TMEM106B, accelerates normal brain aging in older people by up to 12 years, said the report in the journal Cell Systems. The gene generally starts to affect people around 65, particularly in the frontal cortex, which is responsible for higher […]
