Exercise promotes blood flow in the brain and enhances memory in the elderly

May 21, 2020 /PRNewswire/--- In a recent study, scientists found evidence of a link between exercise and brain healthStudies have shown that fitness can improve memory, but what about the specific molecular mechanisms?the study, published by scientists from UT Southwestern, has identified a potentially key process: movement promotes blood flow to two key areas of the brain associated with memoryNotably, the study suggests that blood flow can help improve cognition in older people with memory problems, a finding that scientists say could guide future Alzheimer's research(photo source:the study, published in the journal Journal of Alzheimer's Disease, documented changes in long-term memory and cerebral blood flow among 30 participants, all aged 60 and associated with memory problemsHalf of them received 12 months of aerobic training;the group's memory score improved by 47 percent after a year compared to participants in thestretchexerciseBrain imaging taken at the beginning and end of the study showed a significant increase in blood flow into the cerebral cortex and hippocampus regions of the elderly in the exercise group, which is thought to play an important role in memory functionthis new study is significant because it can map brain improvements in adults at high risk of Alzheimer's disease for a long time"We've shown that even if memory starts to decline, you can still be relieved by increasing aerobic activity," said Thomas, author of thearticle"
more than 5 million Americans currently have Alzheimer's disease, and that number is expected to triple by 2050Recent research has helped scientists gain a better understanding of the molecular origin seifrom of the disease For example, a 2018 study showed that important nerve fibers in the brain called white matter degraded faster in people with lower levels of fitness A study published last year showed that exercise was associated with a decrease in the rate of aging in the hippocampus (Bio Valley Bioon.com) Source: Exercise Boosts Blood flow brain regions with memory
