Earlier this year, Dartmouth researchers added support to mounting evidence about the way that exercise affects learning and mental acuity: it boosts the production of “brain derived neurotrophic factor\" -- or BDNF – a protein that is thought to help with mental acuity, learning and memory.

In the same Dartmouth study, the researchers discovered that, thanks to the BDNF boost, exercise also helped to alleviate ADHD-like symptoms in juvenile rats. Since BDNF is involved in the brain\'s development and growth of new cells, the effect was more profound on the younger rats, with their still-developing brains and more rapid cell turnover, compared to adult rats.

Even one exercise session can help you retain physical skills by enhancing what\'s commonly known as \"muscle memory\" or \"motor memory,\" according to new research published in PlosOne. \n\nAs the New York Times reported, men who were taught to follow a complicated pattern on a computer and subsequently exercised were better able to remember the pattern in subsequent days than the men who didn\'t exercise after the initial squiggle test.

In one study, mice that exercised by running not only generated new neurons, but those neurons lit up when the mice performed unfamiliar tasks like navigating a new environment. (credit:Alamy)

When you exercise, your pituitary gland releases endorphins to help mitigate the physical stress and pain you are experiencing. But those endorphins may play a more important and longer-lasting role: they could help alleviate symptoms of depression, according to a Mayo Clinic report. (credit:Alamy)

Although exercising raises our levels of cortisol -- the hormone that causes physical stress and is even associated with long-term memory impairment -- its overall effect is one of a stress reducer. That\'s because exercise increases the body\'s threshold for cortisol, making you more inured to stressors. (credit:Alamy)

As we get older, an area of the brain called the hippocampus shrinks. That\'s why age is associated with memory loss across the board. However, profound memory loss -- such as in dementia and Alzheimer\'s disease patients -- is also contributed to by accelerated hippocampus shrinking. Luckily, the hippocampus is also an area of the brain that generate new neurons throughout a lifespan. And, the research shows, exercise promotes new neural growth in this area. (credit:Alamy)
