Or they can't find their cars, forget where they are going or get lost in once familiar areas. What the veterans tell me is that they get confused, go off the road, mistake the accelerator for the brake, and have trouble judging stopping distances when they are exposed to gasoline, diesel exhaust, or freshly tarred roads. No one cause can be isolated because there's too much background noise, and patients often underestimate the number of exposures that affect them. This problem is not altogether new. Any one toxicant appears capable of initiating this process.
Symptoms involve several organ systems.
These intolerances are the hallmark of TILT, just as fever is the hallmark symptom of infectious diseases. Exposure to any one or any combination of these toxicants may, in fact, be capable of causing a general breakdown in tolerance that can result in a plethora of beguiling symptoms. We do not know exactly how this breakdown in tolerance occurs. This suggests the breakdown might involve the cholinergic nervous system, which regulates processes throughout the body. The biggest obstacle is the symptoms themselves, which serve as red herrings, diverting attention away from the central problem.
