(NaturalNews) The importance of a nutrient-rich diet in maintaining mental health has been well documented. What may be understated is the value of physical exercise for preserving and even improving brain function. As we age, the brain slowly loses elasticity and as a result memory loss occurs and the risk for dementia increases.
The hippocampus, in particular, plays a vital role in learning and memory. It is this region of the brain that is also very susceptible to atrophy, which can lead to depression and dementia among other health conditions. While exercise improves mental health in general, the prefrontal lobe, which is responsible for personality expression, decision making and moderating social behavior, along with the hippocampus, are most affected by physical activity.
