Background: Organic personality disorder is one of the most pressing problems
of modern practical psychiatry due to the multifactorial etiology of this pathology, the variety
of clinical symptoms, and the complexity of differential diagnosis.
Results: The clinical analysis of a difficult-to-diagnose case of a 13-year-old girl who committed
an act of criminal aggression is presented. Based on anamnesis data, examination
data, analysis of the features of psychopathological symptoms, and dynamic clinical observation,
the final diagnosis of “Organic pseudopsychopathic personality disorder due to
mixed causes (perinatal factors and traumatic brain injury), with significant behavioral disorders
requiring treatment, with schizophrenic symptoms” was made. It was initially mistaken
for the childhood form of schizophrenia based on the clinical pattern and complaints.
Methods: The results of the patient’s clinical examination using a complex of psychodiagnostic
techniques, instrumental research methods, observation data in the department, and an
analysis of the patient’s anamnesis are presented.
Conclusion: The main stages of diagnosis, the course of the study, the difficulties in the
differential diagnosis, and the key insights that played a role in substantiating the diagnosis
