Echolalia is an involuntary repetition of words or sounds made by another person. The repetition can be immediate or delayed. This occurs in Tourette Syndrome, schizophrenia, autism spectrum disorders, aphasia, and dementia. It can also be seen in some children with language acquisition and vision problems. An example of echolalia would be asking a person "Do you want to go outside?". An echolalic response to this questions would be "Do you want to go outside? Yes, I want to go outside."
