Study links insufficient sleep, stress to symptoms resembling concussion ANI | Updated: Jan 25, 2021 08:45 IST Washington [US], January 25 (ANI): While we all know how getting less sleep and stress can be harmful to a person's health, a new study suggested that lack of sleep, pre-existing mental health issues, and stress could also lead to symptoms that resemble concussion. The study was published in the journal 'Sports Medicine'. This finding supports researchers' argument that athletes recovering from a brain injury should be assessed and treated on a highly individualised basis. This study was conducted by the Concussion Assessment, Research and Education (CARE) Consortium established by the NCAA and U.S. Department of Defense.
