The Maudsley's obsessional children: phenomenology, classification, and associated neurobiological and co-morbid...

Area of Science:

• Child and Adolescent Psychiatry
• Neuropsychiatry
• Clinical Psychology

Background:

• Obsessive-compulsive symptoms in children can present without autism, psychosis, or other comorbidities, a group termed Children With Obsessions (CWO).
• Understanding the diagnostic landscape and clinical characteristics of CWO is crucial for effective intervention.

Purpose of the Study:

• To investigate the diagnostic patterns, clinical features, and associated factors in children with obsessions (CWO).
• To compare CWO with non-obsessional psychiatric controls regarding symptom onset, psychosocial factors, and neurological associations.

Main Methods:

• Retrospective analysis of a large database (1968-1983) from Maudsley Hospital.
• Controlled case record study of 100 CWO, comparing them with non-obsessional psychiatric controls.
• Assessment of diagnostic categories, symptom presentation, psychosocial stressors, and neurological findings.

Main Results:

• Only 39% of CWO received an Obsessive-Compulsive Disorder (OCD) diagnosis; the majority had co-morbid diagnoses that shared clinical similarities with OCD.
• CWO experienced a longer delay between symptom onset and presentation compared to controls and were more likely to be from higher social classes (I or II).
• Associated factors included basal ganglia disorders and diffuse brain abnormalities; psychosocial, intra-familial, and treatment-related stresses were higher, but cognitive impairment was not.

Conclusions:

• Children with obsessions often present with complex diagnostic profiles beyond a primary OCD diagnosis, suggesting a broader spectrum of obsessive-compulsive related disorders.
• The significant psychosocial and neurological correlates highlight the need for comprehensive assessment and tailored treatment approaches for CWO.
• Poor treatment outcomes underscore the necessity for prospective studies to refine understanding and improve therapeutic strategies for this population.
