Diagnostic features of paediatric catatonia: multisite retrospective cohort study

Abstract

Background Catatonia is a neuropsychiatric disorder characterised by psychomotor changes that can affect individuals across the lifespan. Although features of catatonia have been described in adults, the most common clinical symptoms among paediatric patients with catatonia are not well characterised. Aims The goal of this study was to characterise the symptoms of catatonia demonstrated by paediatric patients, and to explore demographic and diagnostic factors associated with greater catatonia severity. Method We conducted a multicentre retrospective cohort study, from 1 January 2018 to 6 January 2023, of patients aged 18 and younger with a clinical diagnosis of catatonia and symptom assessment using the Bush Francis Catatonia Rating Scale (BFCRS). Results A total of 143 patients met inclusion criteria. The median age was 15 (interquartile range: 13–16) years and 66 (46.2%) patients were female. Neurodevelopmental disabilities were present in 55 (38.5%) patients. Patients demonstrated a mean of 6.0 ± 2.1 signs of catatonia on the Bush Francis Catatonia Screening Item, with a mean BFCRS score of 15.0 ± 5.9. Among the 23 items of the BFCRS, six were present in >50% of patients (staring, mutism, immobility/stupor, withdrawal, posturing/catalepsy, rigidity), and four were present in <20% of cases (waxy flexibility, mitgehen, gegenhalten, grasp reflex). In an adjusted model, patients with neurodevelopmental disorders demonstrated greater BFCRS severity than those with other diagnoses. Conclusions Catatonia was diagnosed in a range of mental health conditions. Further research is needed to define optimal diagnostic criteria for catatonia in paediatric patients, and clarify the clinical course of the disorder.

Exploring the Trajectory of Catatonia in Neurodiverse and Neurotypical Pediatric Hospitalizations: A Multicenter Longitudinal Analysis

“…The clinical cohort was identified as previously described. 4 Clinical records from two large health systems were queried for patients between 1/1/2018 and 6/1/2023 aged 18 and younger and with a discharge diagnostic code for catatonia (F06.1 or F20.2). Identified records were then manually reviewed and patients included if they had a clinical diagnosis of catatonia, as confirmed in clinical documentation and full Bush Francis Catatonia Rating Scale (BFCRS) 20 documented at the time of initial catatonia diagnosis.…”

“…Catatonia is a neuropsychiatric disorder which occurs across the lifecycle and is characterized by psychomotor disturbance, affective dysregulation, unique physical examination findings, and possible autonomic dysfunction. [1][2][3][4] Symptoms may fluctuate rapidly during periods of illness, for instance at times presenting with muteness and stupor and at other times presenting with repetitive speech and ceaseless motion. Catatonic symptoms can be severe in nature, warranting inpatient medical care due to dehydration, poor intake of food and water, intractable aggression and hyperactivity, and autonomic instability.…”
