Obsessive-Compulsive Disorder from an Embodied Cognition Perspective

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Obsessive Compulsive Disorder (OCD) is characterized by impaired behavioral and cognitive control.
• Current models primarily focus on fronto-striatal dysfunction but fail to fully explain OCD's clinical course.
• A more comprehensive understanding is needed to address the multifaceted nature of OCD pathogenesis.

Purpose of the Study:

• To explore the potential of the Embodied Cognition (EC) perspective in understanding OCD.
• To investigate how alterations in low-level sensory-motor processes may contribute to high-level cognitive dysfunctions in OCD.
• To integrate EC principles into existing models of OCD etiopathogenesis.

Main Methods:

• Theoretical integration of Embodied Cognition (EC) principles with current neuroscientific models of OCD.
• Focus on the role of fronto-striatal circuits in feed-forward motor control (FFMC) and efference copies.
• Hypothesizing the link between efference copy processing failures and the loss of control experienced in compulsive behaviors.

Main Results:

• The EC perspective offers a holistic explanation for OCD by linking sensory-motor deficits to cognitive control issues.
• Dysfunction in efference copy generation or processing within FFMC may be a key mechanism in OCD.
• This framework suggests that impaired efference copies could disrupt the sense of agency, contributing to compulsive behaviors.

Conclusions:

• Embodied Cognition (EC) provides a valuable biological basis for computational theories of OCD.
• Integrating EC offers a novel approach to understanding the neuroscientific underpinnings of OCD.
• This perspective enhances current models by incorporating low-level sensory-motor functions into the explanation of OCD.
