Is exercise good for your brain?

Sep 4, 2013

Hi Dr. Fawcett. a recent study found that exercise reduced neurocognitive impairment by half for people with hiv. but it seems they only asked if the participants exercised within the last 72 hours. This hardly seems like long-term data. Can we trust the results?

Response from Dr. Fawcett

Thanks for writing. You are correct that a limitation of this particular study is the short duration of the exercise period. However, there are numerous studies of the health benefits of exercise and cognition in general, so I think these data are important. HIV-related cognitive disorders can be very subtle, making them difficult to study and quantify. It just seems to be common sense that exercise would benefit cognitive functioning. I believe we'll see more studies in the future that confirm this for HIV-related impairments.

Take care,
