Parallel improvement in two symptom groups can suggest a connection without proving a shared mechanism.
Clinical course in the report
The case described schizophrenia with catatonia and chronic intestinal pseudo-obstruction. Earlier medication approaches were unsuccessful, and modified ECT produced partial improvement. After a later lorazepam escalation, stupor and abdominal distension improved, with restored eating and defecation and a catatonia scale score of zero.
What remains uncertain
This was one patient with a changing, prolonged treatment history. Earlier lower-dose benzodiazepine exposure had not produced the same response. Antipsychotic effects on gastrointestinal motility and other medical conditions complicated interpretation. The proposed GABA–glutamate explanation was a hypothesis, not a directly measured mechanism.
Questions for expert review
For chart review, align bowel function, catatonic signs and actual medication administration across time. Do not assume that improvement in distension establishes a general pro-motility effect of lorazepam. Distinguish the observed joint response from proof that all intestinal pseudo-obstruction in psychiatric patients has the same cause or treatment.
