1 Recently a new study suggested thateven a simple exercise program might helpelders with light memory problems. Doctorshave for a long time advised patients to dophysical activity to help keep their brainshealthy. But the US governmentsupportedresearch marks the longest study of whetherexercise makes any difference once memory starts to decline.

2 Researchers found around 300 inactive older adults with memory changes calledmild cognitive impairment （MCI）. In the research， the participants were divided into twogroups and half of them did aerobic exercises （有氧运动）， while the rest did stretchingand balance movements that raise their heart rates a little. After a year， testing of mentalactivity indicated neither group had worsened， said lead researcher Laura Baker of WakeForest School of Medicine. By comparison， similar MCI patients in another longtermstudyof brain health—but without exercise—suffered from cognitive decline over a year.

3 Maria Carrillo is the Alzheimers Association chief scientific officer. She said earlierresearch has found regular physical activity of any kind may reduce damaging inflammation（炎癥） and increase blood flow to the brain. She added that the new study is particularlyinteresting because the COVID 19 pandemic began halfway through the study. That meantthe study participants became socially isolated. Social isolation has long been known to increase peoples risk of memory problems.

4 It is a struggling time for dementia （痴呆） research. Doctors are not sure about prescribing（开处方） a highpricednew drug called Aduhelm. The drug is supposed to be thefirst to slow down the progression of dementia—but it is not yet clear if it really helps patients.Researchers reported another drug that works similarly failed in an important study. Thereis growing urgency to find whether exercise might offer at least some protection. Baker willlead an even larger study of older adults to see if adding exercise to other steps such as ahealthy diet， brain games and social activities may reduce the risk of dementia.
