A lorazepam provocation test can help identify catatonia in patients misdiagnosed with treatment-refractory schizophrenia, allowing for more targeted treatment.

Maintenance ECT may sustain control in refractory schizophrenia with seizures; leaves open whether controlled trials should test this approach.
Some patients with severe mental disorders are refractory to psychotherapeutic or psychopharmacological interventions. We present a patient who at the age of 19 developed several schizophrenia - suspect symptoms. Soon inexplicable general seizures where observed. He was treated with antipsychotics, but had two bouts of malignant neuroleptic syndrome. Electroconvulsive therapy (ECT) gave some symptom relief and he continued on maintenance ECT for years with weekly intervals. Interruption of this treatment pattern rapidly increased symptom load. After seven years a lorazepam provocation test was performed as he had a new relapse after 3 weeks without ECT. In the ensuing hours his aggressiveness and nonsense speaking rapidly diminished. Kahlbaums observation of seizures as part of a catatonia was not understood in this case. The publication of the new DSM-V diagnosis of catatonia may hopefully reduce the probability of treating a patient for schizophrenia for years without access to a more targeted medication and ECT plan.

John Berg (2014) conducted a case report in Purported schizophrenia / Catatonia (n=1). Lorazepam provocation test and maintenance ECT was evaluated on Symptom relief (aggressiveness and incoherent speech). A lorazepam provocation test rapidly diminished aggressiveness and incoherent speech in a patient with purported schizophrenia and catatonia, allowing for the resumption of maintenance ECT.
