Incidence of psychiatric symptoms in 4- to 8-year-old children with unintelligible speech.
Amorosa H, von Benda U, Wagner E.
Twenty-four children between 4 years 5 months and 8 years of age with unintelligible spontaneous speech and at least average nonverbal intelligence were evaluated over a period of several hours. Nine of the children (37%) were found to have a psychiatric disorder, either a disturbance of emotions specific to childhood (ICD code 313) or a hyperkinetic syndrome (ICD code 314). No relationship was found between the presence of such a disorder and the severity of the speech/language disorder.
