Developmental aspects of mongolism.
To sum up, the testing of neurological responses in our series lends support to the view that whereas psychomotor retardation is a major factor in the development of mongol babies, hypotonia is at the same time of great importance. Our study is not yet complete nor ready for statistical analysis, but the results so far seem to show that mongol babies are particularly retarded in reactions calling for muscular tone, such as posture in ventral suspension and the traction response. It is hoped that as our study proceeds, comparison of neurological with psychological findings will provide another dimension to the interpretation of results. Also we hope to see by long-term follow-up whether the early neurological testing of mongols is of predictive value as regards later development.
