In a study of 454 older individuals (191 with dementia and 263 without), those who were more active than average had better memory and thinking skills than those who were less active than average. This was observed even in participants who displayed physical signs of dementia, such as brain lesions or biomarkers of the disease.
As recently reported in the journal Neurology, the participants underwent yearly physical exams as well as memory and thinking tests over the course of 20 years.
