OCD can first appear at any age, but individuals seem to get symptoms most commonly at either ages 7-12 or in the late teens/young adult years. Research shows us that individuals who develop OCD in childhood are more likely to have a family history of OCD or similar disorders. Additionally, childhood OCD often doesn’t come alone—it tends to show up with other disorders like depression, anxiety, tic disorders, ADHD, and autism. Additionally, because there is significant overlap among symptoms, children may be misdiagnosed.
