Obsessive-compulsive disorder (OCD) is an anxiety disorder affecting one in every one hundred young people in the United States. While OCD is less often recognized and diagnosed than other childhood disorders such as attention deficit hyperactivity disorder (ADHD) and autism, that is changing as the medical community and parents learn to recognize its telltale signs. As treatment rates for OCD continue to increase, many more young people are being spared the disorder's debilitating effects, which can rob them of the joys of childhood. If your child has OCD, your involvement as a loving parent and informed advocate is critically important.
