To verify previously reported hippocampal blood flow abnormalities in ill Gulf War veterans selected from the 24th U.S. Naval Reserve Mobile Construction Battalion (CB), subjects were recruited from a representative national survey of over 8,000 veterans for arterial spin labeling hippocampus perfusion studies. The preliminary results reported here for the sickest of the three major Gulf War illness variants, Syndrome 2, confirm the abnormal hippocampus perfusion observed in Gulf War veterans ill with Syndrome 2 in the previous study of subjects in the CB cohort.
