Pihl, R. O.; Parkes, M.
Science, 198, 4313, 204-206, Oct 77
Hair samples from 31 learning disabled and 22 normal children were analyzed. Significant group differences were determined and a discriminant function was computed which separated the groups with 98 percent accuracy. Elevated lead and cadmium content in the learning disabled group is viewed as being of particular importance. (Author/SL)
