What does this research mean for the field?

Malignant catatonia and non-convulsive status epilepticus can coexist with overlapping GABA-A-related pathophysiology, and resolving the catatonia may require modified electroconvulsive therapy even after epileptiform activity is suppressed. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To describe the diagnostic and therapeutic challenges of distinguishing and treating coexisting malignant catatonia and non-convulsive status epilepticus in a patient with chronic schizophrenia.

Overview

Case report reveals electroconvulsive therapy resolves malignant catatonia in schizophrenia after status epilepticus treatment, highlighting shared GABA-A receptor dysfunction.

Key Points

To describe the diagnostic and therapeutic challenges of distinguishing and treating coexisting malignant catatonia and non-convulsive status epilepticus in a patient with chronic schizophrenia.
Clinical and electroencephalographic evaluation of a 43-year-old male with schizophrenia presenting with post-surgical autonomic instability, consciousness impairment, and motor rigidity.
Sequential administration of levetiracetam for seizure suppression, a lorazepam diagnostic challenge, and subsequent modified electroconvulsive therapy (m-ECT).
Levetiracetam resolved generalized spike-and-wave activity on electroencephalography, but motor rigidity, catatonic signs, and autonomic instability persisted.
Modified electroconvulsive therapy produced marked improvement in motor and autonomic symptoms after 4 sessions, achieving full remission after 13 sessions with sustained recovery over a 5-year follow-up.
