π§ Brain cells might cause age-related thinking dips
New research indicates that myelin-producing brain cells can become dysfunctional, actively contributing to cognitive decline. This was observed in participants from the Lothian Birth Cohort 1936 in Edinburgh, UK. Of 1,091 people, 866 underwent testing after age 70, showing decline rates. Findings overturn the idea that these cells are always helpful, suggesting new treatments targeting this dysfunction. Researchers are excited as this points to strategies to preserve cognition in aging. π§
