## Abstract

The Department of Veterans Affairs (VA) is issuing this interim final rule to amend its adjudication regulation regarding compensation for disabilities suffered by veterans who served in the Southwest Asia Theater of Operations during the Persian Gulf War. This amendment is necessary to extend the period during which disabilities associated with undiagnosed illnesses and medically unexplained chronic multi-symptom illnesses must become manifest in order for a veteran to be eligible for compensation.
