Animal models of OCD-relevant processes: an RDoC perspective

Area of Science:

• Neuroscience
• Psychiatry
• Behavioral Science

Background:

• Animal models are crucial for understanding complex diseases.
• Studying neuropsychiatric disorders like obsessive-compulsive disorder (OCD) presents unique challenges.
• The Research Domain Criteria (RDoC) framework offers a dimensional approach to psychopathology.

Purpose of the Study:

• To review how RDoC constructs can inform OCD research.
• To explore the utility of animal models in understanding OCD pathophysiology.
• To identify key RDoC domains relevant to obsessions and compulsions.

Main Methods:

• Review of recent animal model studies.
• Focus on RDoC constructs: potential threat, habit, and cognitive control.
• Integration of findings from animal research and clinical observations.

Main Results:

• Animal models provide mechanistic insights into RDoC domains relevant to OCD.
• Studies on potential threat, habit, and cognitive control in animals offer valuable perspectives.
• These models help elucidate the complex pathophysiology of obsessions and compulsions.

Conclusions:

• The RDoC framework, combined with animal models, can advance OCD research.
• Mechanistic understanding from animal studies can inform clinical approaches to OCD.
• Future research should integrate dimensional constructs and clinical symptomatology for a comprehensive view of OCD pathogenesis.
