Obsessions are repeated intense and distressing thoughts or mental images, which the affected person attempts to suppress or ignore. Compulsions are repetitive behaviours, performed in response to an obsession or a rigid set of rules. Common obsessions include worries about contamination and germs, or symmetry and exactness; common compulsions include excessive washing of hands, arranging and organizing, counting, and checking.
