Gulf War Syndrome, with its many different types of symptomatic
manifestations, including neurological symptoms, is quite similar to
Chronic Fatigue Syndrome (CFS), Fibromyalgia Syndrome (FMS), and
Multiple Chemical Sensitivities (MCS). This similarity is one avenue
being explored by investigators.
However, many of these symptoms are the general symptoms of disease,
(Hans Selye's "syndrome of just being sick") so it isn't as
informative as it looks on the surface. It's probably more a
reflection of the genetic predisposition for these medical conditions,
rather than a pointer to specific etiology or pathogenesis. (The
range of physical symptoms appears to be significantly affected by
The pathophysiology of these conditions seems to be associated with
reduced cerebral blood flow and possibly reduced levels of the brain
modulatory monoaminergic neurotransmitters (dopamine, norepinephrine,
and serotonin). Not very much is known about this sort of
pathophsyiology because of the difficulty of experimenting on living
human brains. The technique of reverse microdyalysis in laboratory
animals has only recently come into use - I'm only aware of its use in
investigations into alcoholism.
It's now believed that these conditions can be triggered by a wide
variety of causes in susceptible individuals. The $64 question is why
the symptoms don't go away after a reasonable period of time. Two
theories that have been advanced are chronic viral infection, esp. of
the CNS, and non-reversible neurological damage. However, no solid
evidence has been found for these theories in the great majority of
patients despite intensive investigation.
