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.
