Obsessive compulsive disorder in primary care.

Obsessive compulsive disorder (OCD) is more common than previously thought. Because 1% to 2% of the general population has OCD, its prevalence in the primary care setting has to be high. OCD is the fourth most common mental disorder. Recognition of clinical markers will increase diagnostic frequency and hopefully reduce the morbidity caused by the disorder. In addition to early recognition of the disorder, primary care physicians can help demystify the illness because of their relationship with the patient. OCD patients are not only embarrassed by their illness, but they also have a great fear of going "insane." A supportive nonjudgmental attitude will be therapeutic.
