In medical terms, Obsessive Compulsive Disorder (OCD) is a long-term, chronic mental disorder that is characterized by unwanted, intrusive thoughts (obsessions) and repetitive actions (compulsions). Both obsessions and compulsions have direct effects on functioning in day-to-day life, interpersonal relationships, and quality of life. Therefore, the individual with OCD can have intrusive, gratifying thoughts, while compulsions may be recurring acts or mental acts they perform to reduce anxiety.
