MedicalResearch.com: What is the background for this study? 

Dr. Katie Suda: Dentists treat a lot of pain – we have all probably had the experience of a terrible tooth ache.

However, our results show that US dentists prescribe opioids more frequently than is likely needed. This is especially true because studies have shown that non-opioid pain medications are similar or more effective for the treatment of oral pain.

Medical Research: What is the background for this study? What are the main findings?

Response: A large body of data indicates links between chronic physical activity levels and cognitive performance in healthy populations. Although the bulk of evidence comes from studies in older adults, a number of studies have established links in children and in young adults. However, the mechanisms supporting the exercise-cognition links have remained unclear. Finding from an earlier study of ours, published in the journal Neuropsychology, pointed toward cerebrovascular factors as potentially important. In our new study in Psychophysiology, we found evidence suggesting that higher oxygen availability in the brain is one of the cerebrovascular factors that helps support better cognitive performance in people who exercise more regularly, thus providing important insight toward understanding why cognitive performance improves with regular exercise.
