Catatonic syndrome as the presentation of encephalitis in association with COVID-19

COVID-19 has shown different neurological manifestations even sometimes there are the initial or the main presentation.The following case report is about a middle-aged woman who, over 3 days, developed fever, clinical neurological alterations (stupor, muteness, fixed gaze and catatonia), cerebrospinal fluid (16 lymphocytes) and an electroencephalogram (EEG) (4–6 Hz generalised activity) with characteristics of encephalitis. A serum IgG, IgM, nasopharyngeal swab PCR for SARS-CoV-2. The patient responded positively to support measures, symptomatic and corticosteroid treatment. At discharge, the patient was independent and improved considerably.We report the presence of catatonia as a possible and atypical manifestation of encephalitis in association with COVID-19.

Lorazepam-Resistant Catatonia in an Antipsychotic-Naïve 24-Year-Old with Psychotic Symptoms

Catatonia is a complex identifiable clinical syndrome characterized primarily by psychomotor symptoms. In recent decades, some authors have considered that catatonia can be presented as a catatonic syndrome in several pathologies such as bipolar disorder, schizophrenia and other psychotic disorders and not only in schizophrenia. Prior to DSM 5, there were two conceptions of catatonia: one in which clinical characterization seemed to play a determining role (a categorical view) and another in which a dimensional perspective advocated the existence of catatonia as a clinical entity in its own right, detached from the underlying pathology. Although there are no definitive consensus guidelines for the treatment of catatonia, some studies show that in the schizophrenic form of catatonia, benzodiazepines are partially effective, as well as treatment with ECT. We present the case of a 24-year-old man with severe catatonia and psychotic symptoms, resistant to lorazepam treatment, who achieved complete remission with clozapine treatment according to our diagnostic hypothesis of schizophrenia.

The Development of Kraepelin’s Mature Diagnostic Concept of Catatonic Dementia Praecox: A Close Reading of Relevant Texts

Through a close reading of texts, this essay traces the development of catatonia from its origination in Kahlbaum’s 1874 monograph to Kraepelin’s catatonic subtype of his new category of Dementia Praecox (DP) in 1899. In addition to Kraepelin’s second to sixth textbook editions, I examine the six articles referenced by Kraepelin: Kahlbaum 1874, Brosius 1877, Neisser 1887, Behr 1891, Schüle 1897, and Aschaffenburg 1897 (Behr and Aschaffenburg worked under Kraepelin). While Brosius and Neisser confirmed Kahlbaum’s descriptions, Behr, Schüle, and Aschaffenburg concluded that his catatonic syndrome was nonspecific and only more narrowly defined forms, especially those with deteriorating course, might be diagnostically valid. Catatonia is first described by Kraepelin as a subform of Verrücktheit (chronic nonaffective delusional insanity) in his second to fourth editions. In his third edition, he adds a catatonic form of Wahnsinn (acute delusional-affective insanity). His fourth and fifth editions contain, respectively, catatonic forms of his two proto-DP concepts: Psychischen Entartungsprocesse and Die Verblödungsprocesse. Kahlbaum’s catatonia required a sequential phasic course. Positive psychotic symptoms were rarely noted, and outcome was frequently good. While agreeing on the importance of key catatonic signs (stupor, muteness, posturing, verbigeration, and excitement), Kraepelin narrowed Kahlbaum’s concept, dropping the phasic course, emphasizing positive psychotic symptoms and poor outcome. In his fourth to sixth editions, as he tried to integrate his three DP subtypes, he stressed, as suggested by Aschaffenburg and Schüle, the close clinical relationship between catatonia and hebephrenia and emphasized the bizarre and passivity delusions seen in catatonia, typical of paranoid DP.

The Psychopathological Concept of Catatonia

The psychopathological concept of catatonia argues that with the exception of drug-induced extrapyramidal syndromes, modern descriptive psychopathology has neglected the motor aspect of psychiatric disorders. While there has been an upsurge of interest in catatonia, the psychopathological principles underlying its definition remain obscure. The last and only serious attempt to elucidate the psychopathological foundations of the catatonic phenomenon was made by Karl Jaspers more than a hundred years ago. Yet, Jaspers’s views are hardly mentioned in the contemporary literature. The lack of psychopathological foundations has resulted in uncertainties and simplifications regarding the definitions of the individual signs and symptoms and the composition and boundaries of catatonic syndrome. The current literature pays little heed to fundamental aspects of the classical descriptions of catatonia, such as its time-frame, persistence, and consistency, and their relations to other symptoms evaluated in the context of the personality and the situation in which catatonia emerges.

Electroconvulsive Therapy Management in Benzodiazepine-Resistant Catatonic Syndrome: A Case Report

Catatonia is a rare but potentially lethal neuropsychiatric syndrome. Despite its historical association with schizophrenic disorders, it is more frequent in affective ones, and is currently considered an independent pathological entity. The basis of the treatment, regardless of the cause, is the use of benzodiazepines and electroconvulsive therapy (ECT), without a clear consensus on the combined treatment. Regarding ECT, the frequency and number of effective sessions has not been clearly established. Therefore, clinical evolution is the main factor to be considered in order to determinate the appropriate treatment regimen, although the daily application of ECT is preferred, at least for the first week. We report the case of a 41-year-old patient with paranoid schizophrenia, who presented with a benzodiazepine resistant catatonic syndrome. The clinical picture included stupor, mutism, negativism, severe stiffness, catalepsy, waxy flexibility and diaphoresis, with slight CPK increase but with no other extrapyramidal symptoms, fever more than 39 and hemodynamic instability, which allowed to exclude a neuroleptic malignant syndrome. A blood analysis, lumbar puncture, CT, EEG and viral serologies were performed with inconclusive results. The patient required ICU admission and ECT treatment and we used the Bush-Francis Catatonia Rating Scale to evaluate the evolution of symptoms. Six daily treatments with ECT led to an almost full recovery of the patient. Further case series regarding the clinical management of this syndrome are needed, in order to reach consensus on an effective ECT regimen.Disclosure of interestThe authors have not supplied their declaration of competing interest.
