Objective: To know the prevalence of Tic Disorder (TD) in the school children of Tundla district in northern India and to find out the association between Obsessive-Compulsive Disorder (OCD) and Tic Disorder.

Background: Tics are defined as rapid and repetitive muscle contractions resulting in movements or vocalizations that are experienced as involuntary. The TD and OCD, often occurs as a co-morbid condition. Both OCD and TD interfere with emotional, social, familial, and academic experiences. Keeping in view the serious nature of the problem and the dearth of studies based on northern side of India in this regard, the current study was planned to measure the prevalence of TD. Schools, having a major influence on the growing and developing mind of the child, provided an ideal setting to carry out the study. The present study, by identifying children with TD and OCD, intended to bring them under the purview of the Programme on School Mental Health and provide measure of prevention and intervention, as deemed necessary, with the help of mental health professionals, parents, and teachers.

Method: The study was conducted in various schools of Tundla. It is a small district town in Northern India near Agra city. The study was conducted between May2023 to February2024. Out of 15 schools, 4 schools were selected by means of simple random sampling for this study. Ten students from each class were selected by stratified random sampling for screening. Students fulfilling inclusion and exclusion criteria were taken in the study. Tools applied were Socio Demographic and Clinical Data Sheet, Yale Global Tic Severity Scale, Kidde-SADS-Present And Lifetime Version (K-SADS-PL), Chidren‟s Yale-Brown Obsessive Compulsive Scale. The assessments were done in two stages

Results: 240 students from 4 different schools of STD V to STD X were chosen by stratified random sampling. Out of this, 5 students were diagnosed with Tic Disorder. 40 percent students qualified for definite Simple Motor Tic of eye-blinking. 60 percent students qualified for Sniffing-Coughing type of Simple Vocal Tic. Among the 12 students diagnosed of OCD, a group of 3 students also met the criteria for comorbid diagnosis of Tic Disorder. No correlation was detected between OCD and Tic disorder among students.

Conclusion: Out of a sample of 240 students selected from total of 1690 students, Tic Disorder was found in 2.1% and OCD was found in 5%. No association was detected between Tic disorder and OCD
