Palilalia is defined as the repetition of the speaker's words or phrases, often for a varying number of repeats. Repeated units are generally whole sections of words and are larger than a syllable, with words being repeated the most often, followed by phrases, and then syllables or sounds.
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 ...
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 ...
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]). [3]

[1] This symptom is also referred to as association chaining, and sometimes, glossomania. Steuber defines it as "repeating chains of words that are associated semantically or phonetically with no relevant ...
Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. 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 ...
The hallmark deficit of this disorder, however, is in repetition. Aphasic people will show an inability to repeat words or sentences when asked by an examiner. [6] [7] After saying a sentence to a person with conduction aphasia, he or she will be able to paraphrase the sentence accurately but will not be able to repeat it. This is possibly ...
