Obsessive-Compulsive Disorder (OCD) in Children
What is obsessive-compulsive disorder in children?
Obsessive-compulsive disorder (OCD) is a type of anxiety disorder. Obsessions are
recurring thoughts. Compulsions are recurring behaviors.

the fears, such as excessive handwashing.

focus based on age. Preschool children often have rituals and routines around meals,
bathing, and bedtime. These help stabilize their expectations and view of their world.
