“…Every patient presenting with a first episode of catatonia requires a somatic evaluation in search of a potential medical disorder requiring specific treatment [11 ▪▪ ]. In that regard, the benefits of electroencephalography have been recently studied, showing good accuracy in distinguishing neurological and general medical diseases from a primary psychiatric disorder [12 ▪ ] with focal abnormalities, status epilepticus, epileptiform discharges or limbic encephalitis features that are highly specific for nonpsychiatric versus psychiatric catatonia, as opposed to encephalopathy features that are less specific. Blood test, urine drug screen, neuroimaging (MRI), cerebrospinal fluid (CSF) analysis, and encephalitis autoantibodies screening in serum and CSF should also be considered [7].…”

Purpose of review The rising prevalence of neurodegenerative and mental disorders, combined with the challenges posed by their frailty, has presented intensivists with complex issues in the intensive care unit (ICU). This review article explores specific aspects of care for patients with catatonia, Parkinson's disease (PD), and dementia within the context of the ICU, shedding light on recent developments in these fields. Recent findings Catatonia, a neuropsychiatric syndrome with potentially life-threatening forms, remains underdiagnosed, and its etiologies are diverse. PD patients in the ICU present unique challenges related to admission criteria, dopaminergic treatment, and respiratory care. Dementia increases the risk of delirium. Delirium is associated with long-term cognitive impairment and dementia. Summary While evidence is lacking, further research is needed to guide treatment for ICU patients with these comorbidities.

IntroductionCatatonia, a psychomotor disorder characterized by diverse clinical signs, including stupor and mutism, remains elusive in its causes and a challenge to diagnose. Moreover, it is often underrecognized due to its resemblance to disorders of consciousness. However, when diagnosing catatonia, an antipsychotic medication may exacerbate the condition. The first‐line treatment typically includes benzodiazepines and/or electroconvulsive therapy (ECT).Case ReportA 60‐year‐old woman with systemic lupus erythematosus (SLE) and epilepsy presented with catatonic stupor. Despite stable treatment, she experienced an acute deterioration in consciousness, requiring hospitalization. Her condition improved markedly following a benzodiazepine challenge, as documented on EEG. This improvement was short‐lived, but a second benzodiazepine challenge restored her from E1V1M1 (stupor) to E4V5M6 within minutes, as documented by a video recording. The patient was treated with lorazepam 1.5 mg/day orally and did not experience further relapses.DiscussionThe diagnosis of catatonia had been based on her scores on the Bush‐Francis Catatonia Rating Scale (BFCRS; Screening, 6/14; Severity, 19), despite meeting only two DSM‐5 criteria for catatonia (stupor and mutism). The diagnosis was supported by EEG and video documentation, excluding other potential differential diagnoses such as nonconvulsive status epilepticus and encephalopathy. Additional quantitative EEG analyses indicated that benzodiazepine administration increased brainwide alpha and beta band power significantly, suggesting that the benzodiazepine normalized attention, consciousness, and long‐range synchronization. This report additionally emphasizes the significance of video recordings in managing catatonia, and it helps in accurately tracking symptoms, documenting comprehensively, and improving patient understanding, which is crucial for treatment adherence.
