Alalia - the absence or underdevelopment of speech in children with normal hearing. Cause of Allie is the defeat of the speech centres of the brain as a result of violations of fetal development or injuries and diseases of the brain, brought the child up to 1 year, i.e. before the speech. This alalia different from aphasia, which is broken already existed speech. There are motor and sensory alley. When motor Allie a child does not say (publishes only inarticulate sounds), but understanding speech can be saved; at the touch allii the child does not understand speech addressed to him.
Children suffering from alalia, trained in special schools.

Alalia (from the Greek. negative prefix a -, and lalia - speech) - the absence or limitation of speech in children as a result of losing pre-speech period speech zones of the big hemispheres of a brain or their underdevelopment. At diagnosis Allie account should be taken of the hearing, the mechanical causes of violations of articulation, anarchie (see) and disorder of the brain.
Etiology of Allie diverse: the vascular, inflammatory processes, intoxication and traumatic brain injuries, alimentary-trophic, metabolic disorders in the prenatal, Natal and early postnatal development (from 1 to 10 months). Children with mild forms of Allie often to the period of schooling already own phrase speech, but have considerable difficulties in learning to read and write (dyslexia, dysgraphia).
There are motor and sensory alley, respectively, due to a violation of the functions of the frontal-parietal and temporal regions of the big hemispheres of a brain. This division is conditional, as in motor Allie often there are sensory disturbance, and Vice versa. A. may be total.
Motor A. characterized by impaired motor function of the speech when saving basically its understanding. No speech to 2-2 J4 years should inspire fears. Children with motor A. usually ashamed of the defect. They refuse to talk, even if you have some speech margin, showing a kind of "speech negativism"and prefer to use gestures. Having mastered the articulation of speech sounds, these children have difficulties in mastering the sound combinations, resulting in displacement of phonemes, the simplifications; with the advent of the words occur syllabic parafii, for example "lokotok" instead of "hammer." The transition to the phrases reveals agrammatism, which is the most resistant. With the accumulation of vocabulary of agrammatism grows; in children with A. it is expressed in the wrong case endings, no prepositions, conjunctions, dialects. A letter in the period of establishment of speech reflects all the way speech development: it grammatico and full of different profesijai.
Touch alalia characterized by disorders of speech understanding while maintaining elementary hearing. In children with sensory A. violated phonematic hearing and extremely labile auditory attention. In contrast motor A. children suffering from sensory A. exhibit a speech activity even during the prattling of speech. They differ from the hard of hearing and deaf sonorous voice, safety intonation, responses to sound even small intensity, do not use the vision for capturing speech, gestures accompany voice response. Their speech is incomprehensible to others.
For study of patients with motor A. developed a special system that promotes their speech. Teaching methods at the touch of A. little developed. In speech therapy practice is to use some methods. Learning the sounds begin while teaching the letters. Relatively early, work begins on learning the grammatical structure of the language. Cm. also It (disorder).
