Many of us, upon reaching middle age, observe a decline in memory and cognitive abilities. However, the exact molecular changes in the brain responsible for this are not fully understood by scientists.
However, a recent study conducted in mice has revealed that the most significant changes tend to occur in the white matter of the brain, a type of nervous system tissue that’s integral to transmitting signals across the brain. The study also examined two treatments — caloric restriction and infusions of plasma from young mice — that affect certain regions of the brain, with the plasma appearing to slow the age-related decline.
