“…In particular, the sensitivity, specificity, positive predictive value and negative predictive value of the EEG in identifying whether there is a medical or psychiatric cause of catatonia is unclear. Given that most studies of catatonia have small sample sizes, 28 there is a need to synthesise data from multiple reports to reach robust conclusions. A previous systematic review from 1998 examined EEG abnormalities in catatonia due to a medical condition, finding that 84.7% of cases had an abnormality, most commonly diffuse slowing, but this did not include the more recent literature and there was no comparison group of catatonia due to a psychiatric illness.…”

“…[5][6][7] Over the last two decades, research in catatonia and special populations (including the neurodevelopmental population) has expanded exponentially. 8 Several studies have estimated that between 12% and 20% of patients with autism spectrum disorder (ASD) and 18%-32% of children with an underlying psychotic disorder have comorbid catatonia. [9][10][11][12][13][14][15] Catatonia can also be present in various genetic abnormalities (i.e., Down syndrome, 22q13.3 deletion syndrome, Pradar-Willi, and Huntington's disease), tic disorders, intellectual disability, metabolic, endocrine, neurologic, and infectious diseases.…”

Catatonia is a neuropsychiatric condition that causes disruption of movement, emotion, and behaviors. Children and adults with underlying psychiatric conditions are particularly susceptible to developing catatonia, which may result in medical and psychiatric complications. Although catatonia research has been growing at a rapid rate in the last 20 years, it continues to be met with inefficiencies in its diagnosis and incertitude in its treatment. In the pediatric population, catatonia is plagued by diagnostic overshadowing, where the catatonia is erroneously attributed to existing pathologies that lead to a prolonged disease state. This paper describes three pediatric patients with catatonia that fell victim to diagnostic overshadowing. More rigorous training and education are imperative to improve the efficient recognition and treatment of children with catatonia.

“…In particular, the DSM-5-TR lists 12 features of catatonia, of which 3 must be present for catatonia to be diagnosed. In contrast, the Bush Francis Catatonia Rating Scale (BFCRS), 4 the most cited paper in the field of catatonia, 5 consists of a 14-item Bush Francis Catatonia Screening Item (BFCSI) and a full 23-item BFCRS that measures a greater number of signs. The diagnostic structure and features of the BFCRS have been explored in a large cohort of 232 adults with catatonia, 6 which found significant differences in the frequency of observed signs, from 74% with staring to 11% with combativeness.…”

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.
