    INTRODUCTION: Previous research indicates that a large cohort of veterans
    from the 1991 Gulf War report polysymptomatic conditions. These syndromes
    often involve neurocognitive complaints, fatigue, and musculoskeletal
    symptoms, thus overlapping with civilian illnesses from low levels of
    environmental chemicals, chronic fatigue syndrome, and fibromyalgia.

    METHODS: To test for time-dependent changes over repeated intermittent
    exposures, we evaluated objective performance on a computerized visual
    divided attention test in chronically unhealthy Gulf War veterans (n = 22
    ill with low-level chemical intolerance (CI); n = 24 ill without CI),
    healthy Gulf War veterans (n = 23), and healthy Gulf War era veterans (n =
    20). Testing was done before and after each of three weekly, double blind,
    low-level JP-8 jet fuel or clean air sham exposure laboratory sessions,
    including acoustic startle stimuli.

    RESULTS: Unhealthy veterans receiving jet fuel had faster mean peripheral
    reaction times over sessions compared with unhealthy veterans receiving
    sham clean air exposures. Unhealthy Gulf veterans with CI exhibited faster
    post- vs. pre-session mean central reaction times compared with unhealthy
    Gulf veterans without CI. Findings were controlled for psychological
    distress variables.

    DISCUSSION: These data on unhealthy Gulf veterans show an acceleration of
    divided attention task performance over the course of repeated low-level
    JP-8 exposures. The present faster reaction times are consistent with rat
    neurobehavioral studies on environmental toxicant cross-sensitization and
    nonlinear dose-response patterns with stimulant drugs, as well as some
    previous civilian studies using other exposure agents. Together with
    previous research findings, the data suggest involvement of central nervous
    system dopaminergic pathways in affected Gulf veterans.[This Message was Edited on 01/04/2006]

    Toxins, Yes, that's my RANT and I'm sticking to it.

    One doc on TV was telling how dangerous it is to be in an area where there has been a lot of munitions detonated. I guess after the explosions, there is a lot of toxic material. He thought this contributed to GWI.

    I wonder whether there have been any studies of civilians who are exposed to jet fuel. I wonder about refinery workers too. My neighbor has an illness similar to ours which is only triggerd by exposure to petroleum products.

    Love, Mikie
