Developmental progress of preschool Down's syndrome children receiving a home-advisory service: an interim report.

Studies have shown that the progressive slowing of the intellectual development of Down's syndrome children can be minimised by the provision of very early educational input. Such provision has been available from a Home Advisory Service for families with a preschool handicapped child in Clwyd, North Wales, since 1975. The development of these children has been carefully monitored over this time and the findings to date give an encouraging picture in respect of the effectiveness of such a service. They also suggest that the intellectual prognosis for children with this syndrome may be less gloomy than considered hitherto.
