Question 14
Which of the following statements is true about the effects of exercise, physical activity, or
meditation on the functions of the brain?
Regular physical activity increases the risk of dementia and depression.
Meditation hastens the otherwise gradual loss in gray matter.
Regular physical activity protects against cognitive decline.
Exercise inhibits the release of neurotransmitters that elevate moods.
Strenuous exercise inhibits the release of endogenous opioids.

Cognitive decline is significantly reduced by the resultant effects of regularly exercising, engaging in physical activities, or periods of meditation (brief or extended).

Physical activity, exercise, and meditation are all beneficial to the brain with physically active adults being less likely to experience mental decline and Alzheimer's disease. One known modifiable risk factor for dementia according to studies has always been physical activity.

Therefore, regular physical activity actually reduces the risks of dementia and depression as opposed to increasing it; meditation induces and increases gray matter plasticity, and may protect against mood-related disorders and cognitive decline.
