To verify the previous findings and facilitate futher investigation of the pathological characteristics of Gulf War Illness, a semi-blind hippocampus perfusion study with physostigmine challenge was performed for veterans with Gulf War Syndromes 1, 2 and 3 and healthy veterans in two sessions two days apart: the first session with saline infusion and the second session with physostigmine infusion. New study results are similar to those found in the SPECT studies performed in 1997-1998, indicating that the physiological effects upon hippocampal blood flow still persist a decade later.
