The exercise habit that could help lower Alzheimer’s and dementia risk
A brisk walk or regular cycling could potentially boost intelligence, according to neurosurgeon Arun Rajeswaran. He emphasized the importance of cardiovascular exercise over weight training, stating that cardio workouts are particularly beneficial for brain health. Research supports his claim, showing a correlation between increased cardiovascular fitness and improved IQ, verbal ability, and memory. Regular exercise also decreases the risk of Alzheimer's and dementia.
Dr M. Narayana Swamy, Director of Neurosurgery at PSRI Hospital, backed up the scientific evidence of exercise's protective effects on brain health. He explained that cardio exercises, such as brisk walking, jogging, cycling, and swimming, increase blood flow to the brain, ensuring cells receive essential oxygen and nutrients. This, in turn, stimulates the production of brain-derived neurotrophic factor (BDNF), a protein that promotes neuron growth, repair, and survival, maintaining healthy brain connections vital for learning and memory.
Dr Swamy also highlighted the role of cardio in tackling conditions contributing to cognitive decline, including reducing chronic inflammation, improving insulin sensitivity, lowering blood pressure, and decreasing obesity and diabetes risks. Combining physical activity with mentally stimulating tasks, such as solving crossword puzzles, further enhances brain circulation and neuromodulation.
While Dr Rajeswaran suggested that cardio is superior for brain health compared to weight training, Dr Swamy balanced the viewpoint by emphasizing that both forms of exercise are beneficial. He stated that cardio has stronger scientific evidence for reducing Alzheimer's risk, as it directly boosts blood circulation, increases BDNF production, and supports brain plasticity.
However, he advised incorporating both cardio and strength training into a weekly routine, aiming for at least 150 minutes of moderate-intensity cardio and twice-weekly strength training for optimal cognitive health and overall well-being.
