Four stable clusters are identified: contamination and cleaning, doubt and checking, symmetry and ordering, and intrusive thoughts with rituals.
Each subtype links to specific neural circuits, genetic markers, and cognitive traits.
The classification could guide tailored therapies and future research seeks biological markers for diagnosis.
