: obsessive-compulsive disorder

OCD is a disorder that has undergone significant revision and study since it was first recognized as "obsessive-compulsive neurosis" in the first edition of DSM. This definition was modified to "obsessive-compulsive reaction" in DSM-II and became the more familiar "obsessive-compulsive disorder" in DSM-III.
