Distinguishing between the two conditions using electroencephalography (EEG) is crucial. However, reports of NCSE coexisting with catatonia are rare.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>We present a case of catatonia associated with schizophrenia complicated by NCSE. A 77\u2010year\u2010old woman with a 30\u2010year history of well\u2010controlled schizophrenia developed stupor and was admitted to our hospital. EEG revealed evolving spike\u2010and\u2010wave complexes, leading to a diagnosis of NCSE. Administration of levetiracetam improved the EEG findings, and subsequent monitoring confirmed resolution of epileptiform activity. However, the patient's stuporous state persisted despite the normalized EEG. Extensive workup showed no evidence of encephalitis or other neurological pathology. We diagnosed her with NCSE and catatonia associated with schizophrenia. Electroconvulsive therapy (ECT) was administered, resulting in complete resolution of the catatonic symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This case highlights three key points. First, stupor can result from both NCSE and catatonia associated with schizophrenia. Second, when no physical cause for NCSE is identified and symptoms persist despite EEG improvement following antiepileptic treatment, coexisting catatonia associated with schizophrenia should be considered. Finally, ECT was effective in treating catatonia associated with schizophrenia complicated by NCSE. In patients presenting with stupor, it is important to differentiate between NCSE and catatonia associated with schizophrenia and to recognize the potential for their coexistence.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pcn5.70138","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T05:06:25Z","timestamp":1750136785000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Electroconvulsive
