Tourettic Obsessive-Compulsive Disorder
Tourettic OCD (TOCD) refers to a presentation in which Tic Disorders and Obsessive-Compulsive Disorder co-occur in a way that is more than incidental – the two conditions appear to share underlying neurobiological architecture, and their symptoms frequently blur into one another. Individuals with TOCD often describe experiences that don’t sit cleanly within either a standard Obsessive-Compulsive Disorder framework or a standard Tic Disorder framework: “just right” sensations, sensory incompleteness, stimulus-induced tics triggered by specific thoughts or objects, and compulsive-feeling tics that carry an obsessional quality.
TOCD is not yet widely recognised in routine clinical practice, which means many individuals with this presentation are treated using a generic Obsessive-Compulsive Disorder or Tic Disorder protocol that does not fully address the interaction between the two. This matters clinically: treatment that addresses only the obsessive-compulsive features, or only the tics, in isolation often leaves the entwined symptoms undertreated.
Dr. Patel’s doctoral research at the UCL Queen Square Institute of Neurology is specifically focused on TOCD – its phenomenology, its neurobiological basis in cortico-striato-thalamo-cortical circuits, and its treatment implications. This research directly shapes his clinical approach: a hybrid intervention combining Exposure and Response Prevention with Habit Reversal, tailored to address the overlapping mechanisms rather than treating Obsessive-Compulsive Disorder and Tic Disorders as entirely separate problems.
Individuals who suspect their presentation may involve this overlap – whether previously diagnosed with Obsessive-Compulsive Disorder, a Tic Disorder, or both – are welcome to get in touch to discuss whether a TOCD-informed assessment would be appropriate.
