LogoSquareObsessive Compulsive Disorder is one of the most common mental disorders, affecting approximately two per cent of the population (1 in every 50 people). Quite often OCD can be comorbid with another disorder. Comorbid simply means two or more diagnoses are occur in the same person.

The Diagnostic and Statistics Manual (DSM V) has a section for Obsessive Compulsive and Related Disorders. Psychiatrists have grouped four other disorders into the obsessive compulsive family. They are:

  • Trichotillomania (hair pulling disorder)
  • Skin Picking Disorder (excoriation)
  • Hoarding Disorder
  • Body Dysmorphic Disorder

The above four disorders are described in the Related Disorders section of the website because they are closely related to OCD.

In addition to disorders related to OCD, there are some other disorders that are often found to be comorbid with OCD. They include:

  • Anxiety Related Disorders
    • Generalized Anxiety Disorder
    • Social Phobia Disorder
    • Post Traumatic Stress Disorder
    • Specific Phobias
  • Other Related Disorders
    • Obsessive Compulsive Personality Disorder
    • Tourette’s Syndrome
    • Depression
    • Emetophobia

We have included the above disorders in the Related Disorders section of the website because, although not technically related to OCD, they are found to be comorbid with OCD and are often talked about in conjunction with OCD.
