Obsessive–compulsive disorder (OCD) is a mental disorder where people feel the need to check things repeatedly, perform certain routines repeatedly (called "rituals"), or have certain thoughts repeatedly (called "obsessions").[1] People are unable to control either the thoughts or the activities for more than a short period of time.[1] Common activities include hand washing, counting of things, and checking to see if a door is locked.[1] Some may have difficulty throwing things out.[1] These activities occur to such a degree that the person's daily life is negatively affected.[1] This often takes up more than an hour a day.[2] Most adults realize that the behaviors do not make sense.[1] The condition is associated with tics, anxiety disorder, and an increased risk of suicide.[2][3]
