Everyday physical activity, like going for a short walk or playing with the kids, may provide short-term benefits for cognitive health, equivalent to reversing four years of cognitive aging. That was a key finding for my colleagues and me in our new study, which was published in the journal Annals of Behavioral Medicine.
Prior to enrollment into a study of diet and dementia risk, we asked a diverse sample of 204 middle-aged adults to check in five times per day for a period of nine days via a smartphone application.
Each check-in involved completing a brief survey that asked about their mood, dietary choices, and whether they engaged in any physical activity in the roughly three and a half hours leading up to the survey. In addition, participants completed a few brief brain games – meaning performance-based cognitive assessments that lasted about one minute each – to assess mental speed and short-term memory.
