Physical neurologic examination detected no abnormalities in these workers. 469-484. However, only seven referents and one worker reported Agent Orange exposure; the mean serum TCDD level in these eight participants was 43 ppt compared to a mean level of 116 ppt in participants reporting no Agent Orange exposure (p < .10). Dudley AW, Thapar NT. The nerve damage from this condition can have lasting effects. II. Bond GG, Cook RR, Brenner FE, McLaren EA. This suggests that differences in alcohol consumption between veterans and nonveterans were related to demographic differences between the two groups rather than veteran status. Neurological side effects such as tremor, dystonic reactions (twisting movements or postures), parkinsonian-like symptoms, and other dyskinetic (involuntary) movements are less common and are readily managed with dose reduction. The same percentage of workers was found to be depressed at the six year follow-up examination. 1 2. This clinical finding was reinforced in the serum TCDD analysis of the 1987 examination data; Ranch Hands with elevated serum TCDD levels experienced more coordination difficulties than the comparison group (AFHS, 1991). These effects were noted independently of well-established predictors of everyday functioning, indicating the potential importance of neurobehavioral symptoms in predicting the IADL declines that may occur in MA+ individuals .
