esterase (the inhibition associated with OPIDP) nor produce OPIDP in standard testing.

The most important findings of the studies by Haley et al were the objective results of the neurologic examinations. Im¬ portantly, the neurologic findings in these veterans were no different than those of the healthy controls. In addition, inde¬ pendent neurologists reviewed the clinical and laboratory find¬ ings of each subject and were unable to diagnose specific neu¬ rologic disorders. Based on all the studies reported to date, we feel there is still insufficient evidence to suggest that the vet¬ erans' symptoms are caused by toxic exposures or that there are any neurologic disorders specific to the Gulf War conflict.
