Childhood OCD is more common than you might think! Most studies estimate that 1-3% of kids have OCD, although their symptoms are hard to spot and might fly under the radar for a long time.
OCD usually starts when a person is a child or teen, and pretty much everyone with OCD starts getting symptoms before age 25. For childhood-onset OCD, the average age of onset is around 10 years old. It is common for boys to start noticing symptoms a little earlier, while girls might not develop OCD symptoms until later. Some people may not get treatment for OCD until they reach the late teen or adult years, but their problems often began years earlier, during childhood. Addressing symptoms of OCD early can help children manage the disorder and set them up for healthy teen and adult years.
