The purpose of the present study was to objectively verify psychological and behavioral changes in a group of identifiably susceptible patients who were treated for environmental sensitivities in a highly controlled environment. The subjects were 71 Environmental Control Unit (ECU) patient volunteers and 16 nonpatient volunteers for a total of 87. The patients were divided into a short-treatment (fasting 3-4 days) group (n = 35) and a long-treatment (fasting 5-7 days) group (n = 36). A third group, consisting of the 16 nonpatients, formed a nonpatient/no-treatment control group. All subjects were administered tests for assessment of intellectual/cognitive functioning, neurological/cerebral functioning, perceptual-motor skills, mood states, and general psychopathology.
