Do patients of delirium have catatonic features? An exploratory study.
The aim of this study was to determine the prevalence of catatonic symptoms, as per the Bush Francis Catatonia Rating Scale (BFCRS), in patients with delirium and to evaluate the prevalence of catatonia as defined by the Bush Francis Catatonia Screening Instrument and DSM-5 criteria in patients with delirium. ⋯ The present study suggests that a substantial number of patients with delirium have catatonic symptoms and a significant proportion have catatonic syndrome. This high prevalence makes the concurrent diagnosis of delirium and catatonia plausible. The association of catatonia with a specific motor subtype of delirium could encourage the expansion or even modification of the existing subtypes of delirium.
