To determine the generality of lowered NAA/Cr previously measured at 1.5T in bilateral basal ganglia of Gulf War illness patients compared to healthy controls from a single battalion, 1H MRS at 3T of bilateral basal ganglia of control veterans and three illness variants (Syndromes 1, 2, 3) in a subset of subjects from a statistically representative national sample of 8,020 Gulf War veterans was performed. Consistent with previous studies, Syndrome 2 had significantly lower NAA/Cr in left basal ganglia than controls. Syndrome 3 had significantly lower Cho/Cr and significantly shorter Cho T2 in left basal ganglia than controls.
