Abstract

OBJECTIVES:

Catatonia is a unique clinical phenomenon characterized by concurrent motor, emotional, vegetative and behavioral signs. Benzodiazepines (BZD) and electroconvulsive therapy (ECT) can rapidly relieve catatonic signs. The lorazepam-diazepam protocol presented here has been proven to relieve catatonia in schizophrenia within a day.

METHODS:

From July 2002 to August 2011, schizophrenic patients requiring psychiatric intervention for catatonia in Kaohsiung Chang Gung Memorial Hospital were studied by medical chart review. The study used the Bush-Francis Catatonia Rating Scale (BFCRS). Patients receiving the lorazepam-diazepam protocol were identified.

RESULTS:

The survey included 21 patients (eight males and 13 females) with a mean age of 30.3 ± 12.6 years. Mean duration of schizophrenia was 4.7 ± 5.6 years. Thirteen (61.9%) patients responded within 2 h, 18 (85.7%) responded within one day, and all became catatonia-free within a week. Mean BFCRS score was 9.9 ± 3.0 before treatment. Patients that responded with a single intramuscular lorazepam injection had mean BFCRS score of 8.9 ± 2.8, significantly lower than the mean score (11.6 ± 2.5) of the rest of the patients (p = 0.034).

CONCLUSIONS:

The lorazepam-diazepam protocol can rapidly relieve retarded catatonia in schizophrenia. Most patients became catatonia-free within one day but some may require up to a week. ECT should be considered if the protocol fails.
