Symptom profile of catatonia in children and adolescents admitted to psychiatry inpatient unit.

AIM: To study the symptom profile of catatonia in children and adolescents.

METHODOLOGY: Treatment records of all the inpatients aged (≤19 years) were reviewed for the period January 2005 to January 2017. Patients with catatonia (diagnosed as having at least two symptoms as per the Bush Francis Catatonia Rating scale) were included.

RESULTS: During the study period, data was available for 52 children and adolescent. The mean age of the sample was 16.8 years (SD=2.0; range 9-19). Males (N=28; 53.8%) outnumbered females. The most common primary psychiatric diagnostic category was that of psychotic disorders (N=26; 78.8%). One-sixth (N=8; 15.4%) were diagnosed with organic illnesses like epilepsy and systemic lupus erythematosus. Affective disorders accounted for only one-tenth (N=5; 9.6%) of cases, with mania being more common presentation than depression. Very few patients were diagnosed with pervasive developmental disorder (N=2). The common signs and symptoms noted were mutism (90.4%) followed by immobility/stupor (75%), staring (71.2%), negativism (57.7%), rigidity (55.8%) and posturing (53.8%). The mean BFCRS score was 13.73 (SD - 7.6; range 3-20). Overall there was no significant difference in the prevalence of various signs and symptoms of catatonia between those with psychotic disorders, affective disorders and those with catatonia due to organic causes. In only half of the patients catatonia responded to lorazepam and other half required electroconvulsive therapy.

CONCLUSION: The most common symptoms of catatonia in children and adolescent are mutism, immobility/stupor, staring, posturing, negativism and rigidity. The most common underlying psychiatric diagnosis is that of schizophrenia.
