Palilalia is a speech disorder, which is characterized by obsessive reproduction of words or phrases with increasing speed and continuity. The first described this state De Renzi in 1879, later the violation became known as "auto-echolalia"( 1899).
The essence of the disorder is that a person involuntarily repeats the same thing two or more times in a row. For example, after answering the question about the current date( the answer: "I do not know - there is no calendar"), the patient repeatedly repeats the last part of the answer( "no calendar") several times.
The patient can correctly name the date and time, but after that, without stopping, reproduces the said three more times.
This phenomenon is referred to differently as the "gramophone plate symptom" of Mayer-Gross.
Palilalia is characterized by the fact that words as they repeat are made more intermittent or slightly "swallowed".The patient's voice is gradually subsiding, at the same time the speed of uttering increases.
The disorder can manifest itself not only in answering the question, but also in spontaneous statements. Appears in relation to "intellectual speech," expressive utterances, obscene expressions, etc.
Violation usually does not refer to the reprimand of automated speech forms. Repetitions can reach 15 or more times, and at the end the repetition can be "dumb"( "aphonic palalalia").
For what diseases is characteristic of
Palylalia is a sign:
- of a striospallary lesion;
- post-traumatic encephalopathy;
- postencephalic parkinsonism;
- pseudobulbar syndrome with diffuse cerebral vascular injury;
- of Pick's disease, Alzheimer's and others;
- of Tourette's syndrome.
Boiler and co-authors( 1973) described a family pathology characterized by choreic hyperkinesis, dementia and large areas of intracerebral calcification, the main symptom of which was Palilalia.
Symptoms often accompanied by
Symptoms are often combined with emotional lability and cognitive impairment.
Sometimes there is only a movement of the lips, weakly repeating words and sentences( aphonia + palilalia).
The term "palolality" is close to the term "echolalia".This speech behavior, which is expressed in the automatic repetition of heard words and phrases. In children up to 3-4 years this is the norm, in adults it is a symptom of a mental disorder. In literature, one can come across such a notion as "auto-echolalia".
Palyalalia should be distinguished from palyology. This is a behavioral model of some speakers, which consists in the deliberate repetition of words and phrases for the purpose of semantic underscore.
