Brain Exercises Can Accelerate Mental Decline

Exercising your brain can keep you sharp longer into old age, confirmed a new study. But here's the twist: When symptoms of dementia finally settle in, the decline happens faster in those whose brains have been busiest. The research suggests that mind-challenging activities don't actually ward off dementia-inducing diseases. Instead, these exercises prolong the brain's ability to function well despite the degeneration happening within. When symptoms finally do show up, the disease has already progressed to the point of no return. From there, the downhill slide happens fast. Still, the findings emphasize the importance of using your brain as you age. Putting off the clinical onset of Alzheimer's by five years, he said, would halve the number of people who have the disease, though there are still no guidelines about which types of activities are best and how much thinking is enough.
This article is related to Biology because it has to do with how brain exercises speed up the deteriation once it's onset has alreasy begun.
Knowing this is important because it informs people who already perform these excercises that although they delay dementia, they speed up the process.
