Echolalia

Echolalia (/ˌɛkoʊˈleɪliə/; from the Greek ἠχώ, meaning "echo", and λαλιά, meaning "speech") is a phenomenon characterized by the automatic repetition of vocalizations made by another person. It is one of the echophenomena, closely related to echopraxia, the automatic repetition of movements made by another person.

Definition

Echolalia is a term that's used to describe the automatic repetition of sounds, words, or phrases immediately after they're heard. This can occur in many different contexts, including in individuals with certain neurodevelopmental disorders, such as autism spectrum disorder and Tourette syndrome, as well as in those with various types of aphasia or dementia.

Etymology

The term "echolalia" comes from the Greek words "echo", meaning "sound", and "lalia", meaning "talk" or "speech". It was first used in the medical literature in the 19th century to describe a symptom observed in certain psychiatric and neurological disorders.

Types of Echolalia

There are two main types of echolalia: immediate and delayed. Immediate echolalia is when the individual repeats something right after hearing it, while delayed echolalia involves a repetition of the words or phrases after a time delay, which can range from minutes to years.
