Echolalia: Involuntary ("parrot-like"), meaningless repetition of a recently heard word, phrase, or song. This condition may be associated with transcortical APHASIA; SCHIZOPHRENIA; or other disorders. (From Adams et al., Principles of Neurology, 6th ed, p485)Education of Intellectually Disabled: The teaching or training of those individuals with subnormal intellectual functioning.Generalization, Stimulus: The tendency to react to stimuli that are different from, but somewhat similar to, the stimulus used as a conditioned stimulus.Autistic Disorder: A disorder beginning in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual. (DSM-V)Verbal Behavior: Includes both producing and responding to words, either written or spoken.
(1/17) Evolution of technetium-99m-HMPAO SPECT and brain mapping in a patient presenting with echolalia and palilalia.
A 78-yr-old woman presented with transient echolalia and palilalia. She had suffered from Parkinson's disease for 2 yr. Routine laboratory examination showed hypotonic hyponatremia, but was otherwise unremarkable. Brain mapping revealed a bifrontal delta focus, more pronounced on the right. Single photon emission computed tomography (SPECT) of the brain with technetium-99m labeled d,l hexamethylpropylene-amine oxime (99mTc-HMPAO), performed during the acute episode showed relative frontoparietal hypoactivity. Brain mapping performed after disappearance of the echolalia and palilalia, which persisted only for 1 day, was normal. By contrast, SPECT findings persisted for more than 3 wk. Features of particular interest in the presented patient are the extensive defects seen on brain SPECT despite the absence of morphologic lesions, the congruent electrophysiologic changes and their temporal relationship with the clinical evolution.

(4/17) Criminal and legal responsibilities in Tourette's syndrome.
Tourette's Syndrome (TS) is a neuropsychological disorder characterized by the presence of multiple involuntary motor tics accompanied by one or more vocal tics. Articles about TS and criminal responsibility and the restriction of civil rights are limited. A person with TS was evaluated to consider his criminal responsibility after swearing at a referee during a football game. He was also evaluated as to whether or not he was capable of professionally driving a service bus. Additionally, medico-legal situations regarding military service, obtaining a shotgun license and marriages of patients with TS were considered. (+info)
(5/17) Long-term follow-up of echolalia and question answering.
A long-term follow-up of echolalia and correct question answering was conducted for 6 subjects from three previously published studies. The follow-up periods ranged from 26 to 57 months. In a training site follow-up, subjects were exposed to baseline/posttraining conditions in which the original trainer and/or a novel person(s) presented trained and untrained questions. Four subjects displayed echolalia below baseline levels, and another did so in some assessments. Overall, echolalia was lower than in baseline in 80.6% of the follow-ups. Five subjects displayed correct responding above baseline levels. No clear differences were noted in correct responding or echolalia between the trainer and novel-person presentations or between trained and untrained questions. In a follow-up in a natural environment conducted by a novel person, lower than baseline levels of echolalia were displayed by 3 subjects; 2 subjects displayed lower than baseline levels in some assessments. Two subjects consistently displayed correct responding above baseline, and 3 did so occasionally. Issues related to the study of maintenance are discussed. (+info)

(7/17) Increasing spontaneous language in three autistic children.
A time delay procedure was used to increase spontaneous verbalizations of 3 autistic children. Multiple baseline across behaviors designs were used with target responses, selected via a social validation procedure, of two spontaneous responses ("please" and "thank you") and one verbally prompted response ("you're welcome"). The results indicate gains across target behaviors for all children, with occurrence across other stimuli and settings. These gains were validated socially with 10 adults. Furthermore, increases in appropriate language had no effect on levels of inappropriate speech. (+info)
