The effect of choreoathetoid movements and learning disabilities on children’s performances on the Quick Neurological Screening Test was assessed in 43 6-to 8-year-old boys. The subjects were selected based on the presence or absence of choreoathetoid movements and on the presence or absence of learning disabilities. The Quick Neurological Screening Test, a 15-item test designed to identify children with learning problems, was administered. Items from the test were divided into two parts—six items thought to be influenced by the presence of choreoathetoid movements, and nine items not thought to be influenced by such movements.

The results indicated that the learning-disabled boys performed less well than nonlearning-disabled subjects on the six items thought to be affected by choreoathetoid movements. The presence of choreoathetoid movements was not a significant factor. Neither the presence of a learning disability nor the presence of choreoathetoid movements was found to be a significant factor in performance on the remaining nine items.
