Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The Vietnam Era Health Retrospective Observational Study (VE-HEROeS) is a national study on the health and well-being of Vietnam Veterans, including Blue Water Navy Veterans, as well as Veterans who served elsewhere during the Vietnam Era (1961-1975), and similarly aged U.S. residents who never served in the military. The investigators will invite approximately 43,000 Vietnam and Vietnam Era Veterans, and approximately 11,000 members of the general U.S. population to participate in VE-HEROeS. These individuals are scientifically selected to participate; the study is not able to accept volunteers. All participants in VE-HEROeS will be asked to fill out a questionnaire on their military service, general health, age-related conditions, health care use, and the health experiences of their children and grandchildren. A smaller group will be asked to provide the investigators with access to some of their medical records. Topics of special focus for the study include cognition, hepatitis C infection, and neurologic conditions.
