Language Disorders in a Child Psychiatric Center: Demographic Characteristics and Comorbidity

In this study demographic variables and comorbidity were registered in a group of children and adolescents with language disorders. Ss were drawn from 1,151 consecutively admitted psychiatric patients (0-17 yrs) in a 5-yr period. 116 patients had language disorders (10%), and 73% were boys. 27% had expressive language disorders, 47% receptive language disorders, and 26% mixed specific developmental disorders (inclusive language disorder). The prevalence of previously unsuspected language disorders was 27%. 75% of patients with language disorders could furthermore be psychiatrically diagnosed in accordance with 8 main categories of ICD-10. Language disorders were most often found to be comorbid with conduct disorders, and the comorbidity was most frequent in the adolescent group. Boys had significantly more conduct disorders than girls, and girls had significantly more emotional disorders than boys. Findings have clear implications for the psychiatric service to children, adolescents, and their families, since both assessment and treatment are predominantly language-based activities.
