Recent research from Johns Hopkins reveals that just 35 minutes of moderate exercise weekly can reduce dementia risk by 41% in older adults. This groundbreaking study, analyzing data from 90,000 participants, shows even greater benefits with increased activity – up to 69% risk reduction at 140+ minutes weekly. For aged care homes, implementing structured physical activity programs could significantly impact residents' cognitive health, with benefits seen even in frail individuals. Expert Dr. Amal Wanigatunga emphasizes that "even five minutes per day" can make a difference in dementia prevention.
