Anatomy & Body Systems
Compulsions involve dysfunction in specific brain circuits:
Cortico-Striatal-Thalamic-Circuits: These circuits, connecting the cortex, basal ganglia, and thalamus, are involved in habit formation and behavioral control. Dysfunction in these circuits underlies compulsive behaviors.
Prefrontal Cortex: This region is involved in decision-making, impulse control, and interrupting habitual behaviors. Reduced prefrontal function contributes to difficulty stopping compulsions.
Amygdala: This structure processes threat and fear, and its hyperactivity contributes to the anxiety that drives compulsions.
Types & Classifications
Common Compulsion Types
Cleaning/ Washing: Excessive hand-washing, cleaning, or grooming behaviors.
Checking: Repeatedly checking locks, appliances, or other items for safety.
Ordering/ Arranging: Need to arrange objects in a specific way or symmetrically.
Repeating: Repeating actions or phrases a specific number of times.
Mental Compulsions: Counting, praying, or mentally reviewing to prevent harm.
Hoarding: Difficulty discarding possessions, even worthless items.
Causes & Root Factors
Neurobiological Factors: Dysfunction in brain circuits involving serotonin, glutamate, and dopamine contributes to compulsions.
Genetic Factors: Family history increases risk, with heritability estimates of approximately 40-65% for OCD.
