Physical activity can reduce the risk of silent stroke

People who continue to perform moderate and intense physical activity, can reduce the likelihood of small brain lesions. called a “silent” stroke, finds a new study.

Silent (subclinical) stroke is usually not detected as incurred, as are extensive signs of strokes in the form of severe headaches, dizziness, impaired speech and paralysis.

They occur thrombosis or rupture of small blood vessels, as and when clinically evident strokes, which can cause long term problems such as memory loss.

Regular exercise has shown to be effective in the prevention of broad strokes, but their influence on the silent stroke has not been studied.

Moderate, intense or gentle exercise

In a recently published study, researchers from Columbia University in new York and the University of Florida in Miami was attended by approximately 1200 elderly people were missing in the last stroke.

The majority of the study participants went through six decades and at the beginning of the study they were interviewed in detail on the subject of regularity and frequency of exercise.

After nearly 6 years at the age of about 70 years, the participants completed the study of the brain using the method of magnetic resonance imaging.

The results showed that 197 of the participants, or 16%, had small brain lesions, indicating silent strokes.

People reporting moderate and intense physical activity, had lesions less than 40% of cases, compared with people. not engaged in physical exercise at all, even after the researchers took into account other risk factors for stroke, for example, high blood pressure and high cholesterol.

Light exercise, such as Golf, walking, bowling or dancing, do not reduce the risk of silent stroke, but took part in the study doctor and specialist stroke Joshua Willie pointed to their specific health benefits.

Willie is an assistant Professor of neurology at Columbia University.

“I would not want this data has caused the refusal from walking or other light physical activity”, he said. “But it goes to show that a certain level and frequency of physical activity needed to reduce the risk of silent stroke”.

The American heart Association (AHA) recommends at least 150 minutes of moderate physical activity or 75 minutes of intensive exercise a week to reduce the risk of cardiovascular diseases.

In the load range from moderate to intense include brisk walking, working in the garden and around the house, swimming, Jogging, Hiking, bicycling and tennis.

Rapporteur AHA, doctor, specialist stroke Medical University of southern California in Charleston Daniel the big out here told me that, despite the use of exercise for health, the elderly, never receiving physical exercise have to be careful.

“You would not advise a 70 or 80 year old person who has never engaged in Jogging, start doing it,” he says. “But anyone can start physical training with appropriate medical control at any age.”

Willie advises people who have suffered a stroke. consult a doctor before beginning an exercise program.
