Raw data of the clinical trial NCT04076852. We tested, through a chronobiologic approach, the existence of a significant circannual rhythm of tics and obsessive-compulsive symptoms in patients with Obsessive-Compulsive Tic Disorder (OCTD). The chronotype effect on tics and OC symptoms during seasons was also studied. The dataset was used to write the article "Exploring circannual rhythms and chronotype effect in patients with Obsessive-Compulsive Tic Disorder (OCTD): A pilot study", which was published by the Journal of Affective Disorders in 2020. OC symptoms displayed a significant circannual rhythm and were influenced by patients' chronotype. On the contrary, tics resulted similar among seasons and chronotypes.
