Moderate- to high-intensity aerobic and strength exercise did not slow cognitive impairment in dementia, finds a trial published in BMJ.
The 494 participants with mild to moderate dementia (average age 77 years) were randomly assigned 2:1 to a supervised exercise and support program or to usual care. The intervention included 60- to 90-minute group sessions in a gym twice a week for 4 months, plus home exercises for 1 hour each week. After 4 months, participants were prescribed an unsupervised 150-minute per week home exercise program.
