Assessment of Initial Psychotic Symptoms in Pediatric Patients: A Retrospective Study
Overview
This retrospective study evaluated 68 pediatric patients presenting with first-episode psychotic symptoms over 10 years at a tertiary center. Findings highlight that 23.5% had secondary psychosis due to medical or substance-related causes, with younger age and catatonia more common in this group, underscoring the importance of targeted medical evaluation.
Background
Psychotic symptoms in children and adolescents range from normative developmental phenomena to severe psychiatric or medical conditions. Differentiating primary psychiatric disorders from secondary causes such as substance-induced or medical etiologies is critical, as management differs significantly. Current guidelines vary in recommendations for medical workup, and data on clinical features distinguishing these etiologies in pediatric populations remain limited. This study aimed to characterize clinical presentations and evaluation patterns in a tertiary pediatric setting.

Sample size
68 patients
Mean age
13.7 ± 3.7 years
Secondary psychosis cases
16 (23.5%)
Age range
3.1–17.9 years
Key Findings
23.5% of patients were diagnosed with substance-/medication-induced or medically-associated psychosis.
Younger age and very early onset psychosis (<13 years) were more frequent in secondary psychosis cases.
Catatonia at first presentation was more common among patients with secondary etiologies.
Prior subthreshold psychotic symptoms were more often documented in primary psychiatric disorder cases.
Most medical investigations did not identify a secondary cause, reflecting targeted clinician-directed evaluation.
Selected cases demonstrated the clinical importance of thorough assessment for conditions like autoimmune encephalitis and multiple sclerosis.
Clinical Implications
Clinicians should consider targeted medical evaluations in pediatric patients presenting with psychosis, especially when clinical features such as younger age, catatonia, or atypical presentations raise suspicion for secondary causes. A thorough assessment including history, physical examination, and selective laboratory and neuroimaging studies can aid in differentiating primary psychiatric disorders from medical etiologies, guiding appropriate management.
Conclusion
This study supports the utility of a focused, clinician-directed medical workup in pediatric psychosis to identify secondary causes, which are more prevalent in younger patients and those with catatonia. Careful clinical assessment remains essential to inform diagnosis and treatment in tertiary pediatric settings.
