Deep brain stimulation (DBS) for treatment-resistant obsessive-compulsive disorder (OCD) produces profound changes beyond symptom reduction, altering patients' entire way of being in the world. Standard psychiatric scales fail to capture these global effects. The authors propose an enactive, affordance-based model describing four aspects of the person-world interaction: the perceived field of affordances (width, depth, and height); self-experience including mood and feelings; the mode of relating to the world; and the existential stance—the second-order evaluation of these changes. This model aims to specify the phenomenological effects of DBS treatment.
