[Clinical studies of learning disability. Part II: A prospective study of children with risk factors for learning disability at three year-old screening]

We followed children with the risk factors for learning disability (LD) at the three year-old screening prospectively. The five risk factors were speech delay, hyperkinesia, delayed social skill, delayed comparative conception (big and small, long and short) and mutistic behaviour. We evaluated seventeen elementary school children using WISC-R and the Pupil Rating Scale Revised. Six of them were diagnosed as normal, six were learning-disabled, and five were mentally retarded children. We proposed that the screening of LD at three years by the risk factors were effective but only partially.
