Answer

At some point during the course of the disorder, the person recognizes that the obsessions or compulsions are excessive or unreasonable (although this does not apply to children).

The obsessions or compulsions cause marked distress, are time consuming (take >1 hour per day), or significantly interfere with the person's normal routine, occupational or academic functioning, or usual social activities or relationships.

Obsessions and their related compulsions (the latter also referred to as rituals) often fall into 1 or more of several common categories, as seen in the table below.
