This takes considerable time, and she often repeats this 10 to 12 times per day. Her experience is most symptomatic of obsessive compulsive disorder (OCD).  This is a mental disorder that results in repeated unwanted thoughts and the urge repeat an action such as cleaning over and over again. There are four categories of OCD;  checking, contamination, symmetry and ordering, ruminations and intrusive thoughts.
