OCD - Obsessive–compulsive disorder

What is the Obsessive-Compulsive Disorder (OCD)?

The Obsessive–Compulsive Disorder – OCD is characterized by the presence either of obsessions or of compulsive actions, usually of both. These symptoms are quite common in the general population, but in order to speak about a diagnosis such as the Obsessive-Compulsive Disorder (OCD), the symptoms must cause significant functioning impairment and subjective difficulty, and, of course, the patients will have to recognize the irrationality of being occupied with these symptoms.


It is believed that 1-3% of the population presents obsessive-compulsive disorder. This means that in a city such as Athens, it is expected that the Obsessive-Compulsive Disorder (OCD) regards 40,000 to 120,000 of our fellow citizens.

Obsessive-Compulsive Disorder (OCD) belonged, according to the diagnostic manual DSM-IV of the American Psychiatric Association, to the Anxiety Disorders. More recently its properties as a clinical entity were revised, and, at the most recent edition of the DSM-V diagnostic manual, the Obsessive-Compulsive Disorder (OCD) belongs, along with the Body Dysmorphic Disorder (BDD), Trichotillomania / Hair Picking Disorder, Hoarding Disorder, the Compulsive Disorder of Excoriation / Skin Picking Disorder, to the Category of Obsessive Compulsive and Related Disorders – OCRDs.
