The content published on cowac.org — including legislative summaries, policy documents, clinical reference materials, evidence summaries, infographics, and all other materials — is provided for informational and educational purposes only. It does not constitute and should not be construed as medical advice, clinical diagnosis, legal advice, or representation.

For veterans: Information on this Site about blast-related neurological injury, VA service-connection pathways, and occupational exposure is provided to support informed advocacy and to facilitate conversations with qualified medical and legal professionals. It is not a substitute for evaluation by a licensed clinician, and nothing on this Site should be relied upon as a basis for medical or legal decisions. Veterans seeking assistance with VA claims should consult an accredited Veterans Service Organization representative, a VA-accredited claims agent, or a licensed attorney.

For clinicians: COWAC’s clinical reference materials are developed to support provider awareness of occupational blast overpressure exposure and are grounded in peer-reviewed literature. They are not clinical guidelines, do not establish a standard of care, and should be evaluated in the context of each provider’s independent professional judgment and the specific circumstances of individual patients.

For researchers and policy audiences: Legislative summaries and evidence reviews published by COWAC represent the organization’s good-faith interpretation of the available literature and public record. They are advocacy documents, not peer-reviewed research, and should be evaluated accordingly.

COWAC makes reasonable efforts to ensure the accuracy and currency of information published on this Site but makes no warranties regarding completeness, accuracy, or fitness for any particular purpose. The legislative and regulatory landscape governing veteran health policy changes frequently; users should verify current status of any legislation, regulation, or VA policy through authoritative government sources.
