The DOD has been evaluating units for brain health and performance effects of blast overpressure. The United States Special Operations Command is out front leading the way with implementing support activities that address brain health needs in all environments. Emerging information from acute and repetitive exposures to blast has shown adverse effects, such as the inability to sleep, degraded cognitive performance, headaches and dizziness. Our commitment to force health protection and sustaining Warfighter readiness is to understand, prevent, accurately diagnose, and promptly treat blast overpressure and effects in all its forms.
