Other related symptoms include the use of neologisms (new words without clear derivation, e.g. hipidomateous for hippopotamus), words that bear no apparent meaning, and, in some extreme cases, the creation of new words and morphosyntactic constructions. From the "stream of unchecked nonsense often under pressure and the lack of self-correction ...
Other disorders associated with echolalia are Pick's disease, frontotemporal dementia, corticobasal degeneration, progressive supranuclear palsy, as well as pervasive developmental disorder. [10] In transcortical sensory aphasia, echolalia is common, with the patient incorporating another person's words or sentences into his or her own response ...
Vocal imitation happens quickly: words can be repeated within 250-300 milliseconds [1] both in normals (during speech shadowing) [2] and during echolalia.The imitation of speech syllables possibly happens even more quickly: people begin imitating the second phone in the syllable [ao] earlier than they can identify it (out of the set [ao], [aæ] and [ai]).

One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...
