Neurological dysfunction in a large sample of three year old children: a report from the Dunedin Multidisciplinary Child Development Study.
The prevalence of neurological abnormalities was examined in a large sample of Dunedin three-year-old children. About 10 percent of those assessed had one or more abnormalities at three and 2 percent had abnormalities which were judged to have an effect on the child's functioning. The presence of abnormalities at three was associated with language and motor delays at that age and predictive of later IQ deficit. However, abnormalities were not stable over time and their significance for predictive purposes with individual cases is questioned.
