compulsion

Compulsion refers to an irresistible urge to perform an act, often repetitively and without logical reason. This can manifest as obsessions, which are intrusive thoughts or images, or compulsions, which are repetitive behaviors. While compulsions can be performed to prevent an undesirable outcome, the individual often recognizes the lack of a logical connection.12

Obsessive-compulsive disorder (OCD) involves experiencing either obsessions or compulsions, or both. These disorders affect about 2-3% of the population and can be treated with antidepressants like clomipramine and fluoxetine, suggesting a neurochemical basis. Behavioral psychotherapy, particularly exposure therapy, is also an effective treatment for some compulsive rituals.23
