Key points from article :
Research mapping brain changes after one year of aerobic workout revealed a critical process.
That is exercise boosts blood flow into two key regions of the brain associated with memory.
Study showed this can help even older people with memory issues improve cognition.
This is a finding that scientists say could guide future Alzheimer’s disease research.
They have documented changes in long-term memory, cerebral blood flow in 30 participants.
They are 60 or up with memory problems, half did 12 months of aerobics; half, only stretching.
exercise group showed a 47 percent improvement in some memory scores after one year.
Imaging showed increased blood flow into the anterior cingulate cortex and the hippocampus.
These are neural regions that play important roles in memory function.
Enough data seen, to know that starting a fitness program can have lifelong benefits for brain.
