    Physical Activity May Reduce Age-Related Movement Problems

    NIH | MARCH 25, 2015

    Age-related brain lesions known as white matter hyperintensities have been linked to movement problems and disabilities later in life. These lesions, which appear as bright spots on MRI images, can be used as a proxy measure of brain white matter disease. They are thought to reflect small blood vessel disease, and have also have been associated with dementia and other health issues in older people.

    The researchers scanned the brains of 167 healthy older adults who were participating in a larger study of memory and aging. The participants’ average age was 80. The investigators gave the participants various movement and strength tests.

    As expected, the researchers found that more physical activity was associated with better motor function. More age-related brain lesions were generally linked to poorer motor function. Physical activity levels were not related to the amount of lesions.

    However, among participants who were most active, the lesions weren’t linked to poorer motor skills. Other factors like body mass index and vascular disease had no effect on the relationship between the brain lesions, daily activity, and motor function.
