Getting in more daily steps may help slow early brain changes linked to Alzheimer's disease, a new long-term study suggests.
Researchers followed nearly 300 older adults for up to 14 years and found that people who already showed high levels of beta-amyloid (an early sign of Alzheimer's) lost memory and thinking skills more slowly if they were physically active.
Even a low or moderate amount of daily movement made a difference, the study said.
In fact, adults who walked about 5,000 to 7,500 steps a day saw their thinking skills decline at half the rate of people who were mostly inactive, the study found.
