Catatonic schizophrenia, rare severe mental disorder characterized by striking motor behaviour, typically involving either significant reductions in voluntary movement or hyperactivity and agitation. In some cases, the patient may remain in a state of almost complete immobility, often assuming statuesque positions.

- A case study on attenuated forms of catatonic symptoms in schizophrenia: relevance of early intervention with electroconvulsive therapyby Sujita Kumar Kar on October 4, 2021
- Does recurrent catatonia manifest in a similar fashion in all the episodes of mood disorder? A case series with literature reviewby Santanu Nath on October 1, 2021
Catatonia, originally conceptualised by Kahlbaum in 1868, is a neuropsychiatric condition that has been found to occur concomitantly with several organic and psychiatric conditions. Starting from the era of Kraepelin and Bleuler, this condition was faultily linked with schizophrenia alone; however, over time, greater associations have been found between catatonia and mood disorders. Despite the availability of several reports supporting this finding, there is a relative paucity of studies that...
- Intrinsic neural network dynamics in catatoniaby Fabio Sambataro on September 29, 2021
Catatonia is a transnosologic psychomotor syndrome with high prevalence in schizophrenia spectrum disorders (SSD). There is mounting neuroimaging evidence that catatonia is associated with aberrant frontoparietal, thalamic and cerebellar regions. Large-scale brain network dynamics in catatonia have not been investigated so far. In this study, resting-state fMRI data from 58 right-handed SSD patients were considered. Catatonic symptoms were examined on the Northoff Catatonia Rating Scale (NCRS)....
- Refractory catatonia in old age: a case reportby Emma Bean on August 14, 2021
CONCLUSIONS: Catatonia should be considered promptly as a differential diagnosis in older people presenting with atypical features of functional mental illness. Although partial improvement of catatonic features was achieved using benzodiazepines and electroconvulsive therapy, these were not sustained in our patient. We identified comorbid autistic spectrum disorder, prolonged duration of catatonia, and sensitivity to benzodiazepines as important factors in prognostication in old age.
