Making the Diagnosis
Generally, the disorder is diagnosed if the repetitive thoughts or behaviors interfere with daily activities, are time-consuming, and cause distress. Sometimes, diagnosing OCD is difficult because a person with the condition performs their rituals or compulsions privately. Also, people with the condition may be aware that something is wrong but may feel afraid to seek help.
If OCD is suspected, the doctor may first perform a physical examination and obtain a medical history to help make the diagnosis.
