This hypoperfusion is further decreased on exposure to, for instance, perfume. Mathematical tasks did not light up the appropriate areas of the brain. He suggests possibilities for these findings. These kinds of brain effects were actually detected in a study on DDT in 1966. This research was never followed up.
Porphyrias are deficits of certain enzymes required for the production of heme.
Cytochromes also convert some substances to more hazardous forms. Bonnye Matthews, in this chapter, gives a clear explanation of the process. She demonstrates that for the first time a model of MCSS is possible. Some Gulf War veterans have also tested postively for toxic-induced porphyrias. The information in this chapter on the substances which can set off a porhyria attack is vital.
