A case of comorbidity of schizophrenic catatonia and chronic intestinal pseudo-obstruction Successfully managed with lorazepam

It is challenging to manage schizophrenic catatonia and comorbid chronic intestinal pseudo-obstruction (CIPO). The pathology of catatonia is unclear. There are few reports or research on this issue. In this case, we present a middle-aged woman diagnosed with schizophrenia with catatonic features and comorbid CIPO. In the treatment process, modified electroconvulsive therapy (mECT) improved her stupor and CIPO partially. Lorazepam alleviated her stupor and CIPO completely. It is the first report describing complete remission with lorazepam in patient suffering from comorbid schizophrenic catatonia and CIPO, which may benefit the exploration of pathophysiology and treatment of comorbidity of schizophrenia with catatonia and CIPO
