Alzheimer’s disease (a condition that causes irreversible nerve damage to the brain), affects one in every 10 people above the age of 65. Unlike many other diseases, most people are unaware that a healthy and active lifestyle can significantly lower the risk of dementia and Alzheimer’s disease. Dr Rajiv Anand, Director and HOD, Neurology Department, BLK Super Speciality Hospital, New Delhi says, ‘People leading a sedentary lifestyle are at an increased risk of Alzheimer’s because the chances of the brain turning inactive, both structurally and functionally is high. Therefore, it is recommended that people exercise regularly in order to keep the brain active and therefore lowering the risk of Alzheimer’s.’
How exercise helps in improving cognitive function?
Being physically active not only keeps the brain robust but also improves the overall health of an individual. Also, regular exercise helps maintain proper blood flow to the brain, activating the brain cells and preventing nerve degeneration. Dr Rajiv Anand says, ‘Physical activity stimulates the release of brain chemicals to protect it from inflammation or damage along with counteracting the natural damage to the nerve connections that occur with age.’ In this way, exercising not only improves the cognitive function but also reduces the risk of Alzheimer’s and other conditions like diabetes, stroke and heart attacks.
What kind of exercises is good for people with Alzheimer’s?
According to Dr Rajiv Anand, ‘moderate physical activity done on a daily basis is sufficient to slow down the progression of Alzheimer’s disease. Repetitive exercises like indoor bicycling, folding laundry and walking are good for Alzheimer’s as these don’t require the patient to remember any steps (as in case of normal exercise or yoga).
For better and effective results, the patients are advised to continue exercise in combination with a brain-healthy diet, social interaction and mental activity. Apart from preventing muscle weakness and health complications related to physical inactivity, exercising improves mood, promotes normal day-and-night routine and decrease anxiety in Alzheimer’s.
