Clinical significance of childhood communication disorders: perspectives from a longitudinal study

A group of 202 children who were referred for evaluation of communication disorders were also evaluated for psychiatric and learning disorders at two points in time. High rates of both psychiatric and learning disorders were found at initial evaluation, and even higher rates were found at follow-up 3 to 4 years later. Recovery from communication disorder occurred in approximately one fourth of the cases and varied widely depending on the type of disorder involved. Poor psychiatric outcome could be predicted by the presence and severity of initial disorders of language comprehension and expression, and by certain environmental factors (such as psychosocial stress). The high prevalence of linguistic, psychiatric, and development disorders at follow-up for the children in this study suggests the need for close monitoring of children with early communication impairments.
