The Board granted service connection for hyperthyroidism, as a medically unexplained chronic multisymptom illness (MUCMI), based on the Veteran's service in Southwest Asia.
The deciding factor: Service connection was granted after resolving any reasonable doubt in favor of the Veteran due to the January 2021 VA examination report indicating that his hyperthyroidism is a 'diagnosable but medically unexplained chronic multisymptom illness of unknown etiology.'
