Abstract

BackgroundCatatonia has been associated with both schizophrenia and pervasive developmental disorders.
The aim of this study was to evaluate catatonic features among adolescents suffering from schizophrenia.
Further, we compared these features between adolescents with a comorbid pervasive developmental disorder and those without one.
Finally, we wanted to compare the profile of catatonia-like features of our schizophrenia patients to that described earlier among persons with autism spectrum disorders.

MethodsThe study comprised a consecutive sample of 18 adolescents with schizophrenia mean age 15.6 years, SD 1.4 and their families.
Diagnosis of schizophrenia was assessed with the Schedule for Affective Disorders and Schizophrenia for School-Aged Children – Present and Life-Time K-SADS-PL for the DSM-IV.
The Diagnostic Interview for Social and Communication Disorders version 11 was used to assess catatonic features.

ResultsAll adolescents with schizophrenia had showed some lifetime catatonic features.
Approximately 78% of them had already expressed these features before the age of 10.
The number of catatonic features before the age of 10 was significantly higher among the adolescents with a comorbid pervasive developmental disorder compared to those without one.
The numbers of catatonic features after the age of 10 did not significantly differ between the two groups.
Over three-quarters of schizophrenia patients shared four lifetime catatonic features: -lacks facial expression- -odd intonation- -poor eye contact- and -lack of cooperation-.

ConclusionsAdolescent schizophrenia patients with a comorbid pervasive developmental disorder show many catatonic features in childhood whereas those without one seem to develop these features first in adolescence.
Catatonic features exhibited by adolescents with schizophrenia resemble those described among persons with pervasive developmental disorders without schizophrenia.
