Catatonia and melancholia interface: exploring a new paradigm for evaluation and treatment. A case series and literature review.

Background: Catatonia has been increasingly associated with mood disorders and is recognized as a specifier in the DSM-5 and DSM-5-TR. The DSM-5-TR recognizes melancholia as a specifier for depressive episodes in major depressive disorder and bipolar disorder. It is characterized by severe anhedonia, lack of reactivity, excessive or delusional guilt, and significant vegetative symptoms. As the conceptualization of melancholia expanded beyond its mood components to include psychomotor disturbances, its overlap with psychomotor symptoms or catatonia becomes evident. This overlap was also described in Kahlbaum's original literature, where he describes the transition between states of melancholia, mania, and catatonia. Method: Case summary of six patients with major depressive disorder or depressed phase of bipolar disorder who were admitted for severe depression, anhedonia, intense anxiety, psychomotor agitation or retardation, indecisiveness, perseveration, and vegetative symptoms such as poor sleep, appetite, and significant weight loss. Results: All patients demonstrated rapid and complete resolution of their mood and psychomotor symptoms, indecisiveness, perseveration, as well as psychosis shortly after administration of lorazepam, with recurrence of the above symptoms upon lorazepam discontinuation and resolution upon resumption, in an on-and-off manner. Conclusion: The present study argues for a closer relationship between melancholia and catatonia based on our case series, historical review, overlap in phenomenology, and response to treatment. We propose provisional [Mahgoub] criteria for patients with severe depression and melancholia. The role of GABA agonists, such as lorazepam, can be explored as an option for patients with treatment-resistant depression who meet these criteria for melancholia. Limitations: Absence of a standardized, systematic assessment tool and a small sample size.

Electroconvulsive Therapy-Resistant Catatonia: Case Report and Literature Review.

BACKGROUND: Untreated catatonia is associated with serious medical complications that can necessitate urgent medical attention. Lorazepam and electroconvulsive therapy (ECT) are effective for catatonia across various psychiatric or medical diagnoses. In rare cases, ECT fails to achieve full response in catatonic symptoms, particularly in patients with chronic catatonia or primary psychotic disorder. Evidence on treating catatonia that does not respond to ECT is lacking. OBJECTIVE: Conduct a literature review on treatment of ECT-resistant catatonia which is defined as that reported lack of full response to ECT treatments. We present a case of a 52-year-old male with schizophrenia where catatonia did not respond to lorazepam and robust ECT but resolved after memantine titration. METHODS: A literature review was performed using Medline/PubMed with the following keywords: treatment-resistant, catatonia, electroconvulsive therapy. References in eligible articles and most recent systematic reviews on catatonia treatment were reviewed. RESULTS: Seventeen patients in 12 case reports were identified where the treatment of catatonia was described after failed ECT trials. Most had chronic catatonia and a diagnosis of schizophrenia. ECT parameters and ictal outcome measures were not consistently reported. Treatment modalities for ECT-resistant catatonia included amantadine, memantine, lorazepam augmentation to ECT, and antiepileptic and antipsychotic medications such as aripiprazole and clozapine. CONCLUSIONS: The literature review and new case suggest reconsideration of catatonia diagnosis, optimizing ECT treatments, cautious use of antipsychotics, consideration of lorazepam augmentation to ECT treatments, and/or use of N-methyl-D-aspartate receptor antagonists.

New-Onset Catatonia and Delirium in a COVID-Positive Patient.

Coronavirus disease (COVID-19) is a strain of coronavirus family, which was initially found in China in late 2019 and subsequently spread to rest of the world. COVID-19 has led to physical and mental health complications since its onset. In addition to the pandemic-associated social stresses, biological complications include direct viral encephalitis, autoimmune-mediated responses, medication side effects, hypoxic brain injury, and delirium, which can collectively cause varied presentations of neuropsychiatric symptoms. Neuropsychiatric complications have been reported in the acute stages of COVID-19 and post-infection period. Here we report our experience treating a patient who initially presented with a severe depressive episode and subsequently developed catatonia and delirium following hospital-acquired COVID-19 infection.

Electroconvulsive Therapy for Depression in Transgender Patients: Case Series and Literature Review.

ABSTRACT: There is very limited information regarding the effectiveness of electroconvulsive therapy (ECT) as a treatment for major depressive disorder in transgender patients. This population is also at risk for comorbid conditions, such as posttraumatic stress disorder and substance use that could impact the outcome of ECT. We report our experience with the use of ECT in this population. Clinical and response characteristics of 7 consecutive cases are described in this series. All patients had multiple psychiatric diagnoses and were refractory to pharmacologic intervention. Pretreatment Beck Depression Inventory-II scores were 45.5 ± 3.2 SEM and posttreatment scores were 21.2 ± 6.4 [P < 0.01]. Suicidality scores reduced by greater than 60%, whereas remission of depression was obtained for 2 of 7, and 4 of 7 showed greater than 50% reduction in depression scores. Treatments were tolerated well using conventional treatment procedures. This case series suggests that ECT can be effective for depressed transgender patients with multiple clinical comorbidities.

Catatonia revived: a unique syndrome updated.

Catatonia was buried within the confines of schizophrenia for over a century- deterring study, appropriate diagnosis and treatment for many years. With revised changes in the classification of this distinct neuropsychiatric syndrome, it is becoming more recognized clinically and in ongoing research. Catatonia occurs among various psychiatric, metabolic or neurologic conditions. It may present in many forms, including neuroleptic malignant syndrome. Treatment with benzodiazepines or electroconvulsive therapy usually produces dramatic and rapid response, although systematic, randomized trials are lacking. The role of antipsychotic agents in treatment is controversial as they may worsen the syndrome. An important unresolved clinical question is the diagnosis and treatment of catatonia in the setting of delirium.

Outcome of Youth with Early-Phase Schizophrenia-Spectrum Disorders and Psychosis Not Otherwise Specified Treated with Second-Generation Antipsychotics: 12 Week Results from a Prospective, Naturalistic Cohort Study.

OBJECTIVES: The purpose of this study was to assess differences in the outcomes of youth with schizophrenia-spectrum disorders (SCZ-S) and psychotic disorder not otherwise specified (PsyNOS) during early antipsychotic treatment. METHODS: The study was a prospective, naturalistic, inception cohort study of youth ≤19 years old with SCZ-S (schizophrenia, schizoaffective disorder, schizophreniform disorder) or PsyNOS (PsyNOS, brief psychotic disorder) and ≤24 months of lifetime antipsychotic treatment receiving clinician's choice antipsychotic treatment. Baseline demographic, illness and treatment variables, and effectiveness outcomes were compared at 12 weeks last-observation-carried-forward across SCZ-S and PsyNOS patients, adjusting for significantly different baseline variables. RESULTS: Altogether, 130 youth with SCZ-S (n=42) or PsyNOS (n=88), mostly antipsychotic naïve (76.9%), were prescribed risperidone (47.7%), olanzapine (19.2%), aripiprazole (14.6%), quetiapine (11.5%), or ziprasidone (6.9%). Compared with those with PsyNOS, SCZ-S youth were older (16.4±2.1 vs. 14.8±3.2, p=0.0040), and less likely to be Caucasian (19.1% vs. 42.5%, p=0.009). At baseline, SCZ-S patients had significantly higher Clinical Global Impressions-Severity (CGI-S) scores (6.0±0.9 vs. 5.5±0.8, p=0.0018) and lower Children's Global Assessment Scale (CGAS) scores (29.6±9.2 vs. 36.1±8.9, p=0.0002) and were more likely to be in the severely ill CGAS group (i.e., CGAS≤40). SCZ-S and PsyNOS patients did not differ regarding all-cause discontinuation (40.5 vs. 40.3%. p=0.49), discontinuation because of adverse effects (12.2% vs. 12.4%, p=0.97), or nonadherence (29.3% vs. 30.9%, p=0.88), but somewhat more SCZ-S patients discontinued treatment for inefficacy (19.5% vs. 7.4%, p=0.063). CGI-S and CGAS scores improved significantly in both diagnostic groups (p=0.0001, each). Adjusting for baseline differences, PsyNOS patients experienced significantly better CGI-I improvement (CGI-I) scores (p=0.012) and more frequently reached higher categorical CGAS group status (p=0.021) than SCZ-S patients. CONCLUSIONS: Both youth with SCZ-S and those with PsyNOS experienced significant improvements with clinician's choice antipsychotic treatment. However, treatment discontinuation was common within 12 weeks, with greater inefficacy-related discontinuation in the SCZ-S group, whereas CGI-I and CGAS score-based improvements were greater in the PsyNOS group.
