These disorders are defined clinically but lack objectivecharacterization. To meet this need, we measured neurobehavioral and pulmonary functions in eight ASDboys aged 8 to 19 years diagnosed clinically and compared them to 145 unaffected children from acommunity with no known chemical exposures. As 6 of 35 consecutive mold/mycotoxin (mold)-exposedchildren aged 5 to 13 years had ASD, we compared them to the 29 non-ASD mold-exposed children, andto the eight ASD boys. Comparisons were adjusted for age, height, weight, and grade attained in school. Theeight ASD boys averaged 6.8 abnormalities compared to 1.0 in community control boys. The six mold-exposedASD children averaged 12.2 abnormalities. The most frequent abnormality in both groups was balance,followed by visual field quadrants, and then prolonged blink reflex latency. Neuropsychological abnormalitieswere more frequent in mold-exposed than in terbutaline-exposed children and included digit symbol substitu-tion, peg placement, fingertip number writing errors, and picture completion. Profile of mood status scoresaveraged 26.8 in terbutaline-exposed, 52 in mold exposed, and 26 in unexposed. The mean frequencies of35 symptoms were 4.7 in terbutaline, 5.4 in mold/mycotoxins exposed and 1.7 in community controls.
