People with memory issues could prevent the onset of Alzheimer’s disease by exercising more than once a week, suggests a recent study. Regular exercise is thought to boost molecules that support the growth and survival of neurons, or increase blood flow to the brain.
Researchers in South Korea examined the likelihood of developing Alzheimer’s disease in nearly 250,000 patients with mild cognitive impairment — patients with more memory and thinking struggles than is normal for someone their age. People with mild cognitive impairment are ten times more likely to develop the disease in comparison with the general population.
The researchers found that those who carried out moderate physical activity for at least ten minutes more than once per week had an 18 percent lower risk of developing Alzheimer’s disease. Among the patients who exercised, those who exercised three to five times per week had a 15 percent lower risk of developing the brain disease than those who exercised less than that.
Patients who started exercising after their diagnosis of mild cognitive impairment had an 11 percent lower risk of developing Alzheimer’s. Stopping exercising after a diagnosis was associated with the same risk of developing the disease as not exercising before or after the diagnosis.
