Regular exercise reduces the risk of developing Alzheimer’s disease, say scientists from the Medical center of Vanderbilt University, who discovered the link between poor heart health and memory problems.
According to the data obtained in elderly people whose hearts are bad distilled the blood, restricted blood flow in the temporal lobe – the region where it begins to develop dementia. In addition, people who had low levels of physical activity and poor heart health, brain health was 20 years older than the statutory age. Experts warn that the results should serve as a warning to all people, stimulating to devote to physical activity at least 30 minutes five times a week to reduce the risk of developing neurodegenerative disorders.

The study involved 314 people with an average age of 73 years. About one third of subjects (39%) had a mild cognitive disorder that increases the risk of developing Alzheimer’s, while others showed normal cognitive function. The researchers used echocardiography to measure cardiac blood flow and MRI to evaluate the blood supply to the brain. It was found that the poor health of the heart can wear out the brain for 20 years. According to experts, in the elderly it is especially important to make time for physical activity to improve blood flow in the brain, as the more exercise a person performs, the lower the risk of dementia.
