Challenges in the diagnosis and treatment of pediatric obsessive-compulsive disorder

Area of Science:

• Child and Adolescent Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Obsessive-compulsive disorder (OCD) affects 1%-3% of children globally, significantly impacting patient and family well-being.
• Etiology is not fully understood, but neuroimaging, genetic studies, and medication efficacy point to altered cortico-striato-thalamocortical circuits.
• Delayed diagnosis is frequent, leading to severe functional impairment and long-term developmental issues.

Purpose of the Study:

• To outline a clinical approach for diagnosing and managing pediatric OCD.
• To highlight challenges and knowledge gaps in current OCD management.
• To review treatment strategies for both typical and refractory cases.

Main Methods:

• Comprehensive literature review focusing on diagnosis, assessment, and treatment of pediatric OCD.
• Analysis of data from neuroimaging, genetic studies, and clinical trials.
• Synthesis of information on interdisciplinary approaches, including pharmacotherapy and cognitive behavioral therapy.

Main Results:

• Clinical assessment involves detailed symptom history, comorbidity evaluation, and standardized tools for tracking severity.
• A combined approach of cognitive behavioral therapy and serotonin reuptake inhibitors is effective for most children.
• Some children experience a chronic, episodic course, with limited guidance for refractory cases.

Conclusions:

• Effective management of pediatric OCD requires an interdisciplinary approach, integrating therapy and medication.
• Further research is needed to address treatment-refractory OCD and fully elucidate its etiology.
• Early diagnosis and intervention are crucial for mitigating functional impairment and improving long-term outcomes.
