About This Condition
A category covering medically unexplained symptoms that veterans report following qualifying Gulf War service but which do not fit into a recognized diagnostic category after thorough medical evaluation. The VA recognizes undiagnosed illness as a presumptive condition for Gulf War veterans, acknowledging that the complex toxic and environmental exposures of that conflict caused real, disabling symptoms.
Evidence Needed
- Comprehensive medical evaluation documenting symptoms
- Documentation that standard diagnoses have been ruled out
- Documentation of qualifying Gulf War service (Southwest Asia, 8/2/1990 or later)
- Onset of symptoms during or after qualifying service
