Obsessive-compulsive disorder (OCD) is an anxiety disorder characterised by the presence of distressing thoughts (obsessions), recurrent and stereotyped behaviours (compulsions), and repetitive behaviours, over time causing anxiety and impairment in daily life. Although the subject is aware that their obsessions are irrational, they cannot control them. They usually try to suppress them or get some relief through their compulsions. The most common compulsive actions include: repetition and verification: the subjects repeat actions of obsessive doubts (for example, ensure that the gas is off because of fear of an explosion); Cleaning: people who suffer from fear of contamination will wash and clean with disproportionate frequency; Order: such as individuals needing things to be arranged according to a rigid or symmetrical order; or Storage: people who cannot get rid of insignificant objects.
