ELI5: Explain Like I'm 5

Obsessive–compulsive spectrum

Obsessive–compulsive spectrum is when people do things over and over and over again even though they don't want to or know why they are doing it. It can be things like counting things a lot, checking the same things several times to make sure they are done right, or arranging things in a very organized way. People with these kinds of symptoms might feel like they need to do these things or they might feel anxiety if they stop.
