Article Synopsis
  • The authors proposed new diagnostic criteria for catatonia, called the Research Diagnostic Criteria for Catatonia (RDCC), which require three specific symptom clusters to improve diagnostic accuracy compared to existing methods.
  • The RDCC categorizes symptoms into akinesia, unusual motor signs, and behavioral signs, and was tested on a diverse group of 341 patients across various conditions.
  • Results indicated that using the RDCC resulted in significantly lower catatonia diagnoses among the patient groups when compared to DSM-5 and BFCRS criteria, suggesting a more restrictive approach may better identify true cases of catatonia.
