Can aerobic exercises reduce cognitive decline in Alzheimer’s patients? – Results from a new randomized controlled trial.
Physical exercise is an important part of a healthy lifestyle, contributing to general fitness, muscle control and coordination, and to a sense of wellbeing. Physical exercise is also essential for maintaining adequate blood flow to the brain and may stimulate brain cell growth and survival. Evidence of the effects of physical exercise in the prevention of dementia have been supported by many observational studies. The results of randomized trials suggest that exercise leads to increases in brain tissue, including the hippocampus and elevate blood levels of brain derived neurotrophic factor (BDNF), stimulating the formation of new nerve cells.
