Transcript of Dissolution
Wernicke's Aphasia Broca's Aphasia Speech and writing are slow, very hesitant, and in severe cases, completely inhibited.
Automatic speech and function words an remain almost unaffected, usually the production of key words, like subjects, verbs, and objects, is hesitant and inaccurate. Wernicke's Aphasia Speech production and writing are pretty much intact, but patients experience a great deal of trouble processing linguistic input. The patients tend to ramble somewhat incoherently. Two kinds of surgical operations have bearing on question of language dissolution:
Hemispherectomy: neurosurgeons will open up the affected side of the skull and remove almost the entire left or right hemisphere
Split-brain operation:the surgeon makes a front-to-back incision along the corpus callosum, severing most of the association pathways which connect the hemispheres. HEMISPHERECTOMY SPLIT-BRAIN Dissolution from non-damaged brains • Stuttering: Refers to as stammering, is one of the most common articulation problems. It is not random; it occurs, most frequently on the initial word of a clause, the first syllable of a word, the initial consonant of a syllable, and on stop consonants. •Down’s syndrome: The degree of language disability is directly proportionate to the amount of cognitive damage. The enlargement of the tongue creates poor articulation, and though comprehension is not significantly affected, expressive speech is hesitant and limited. Autism: It is not language impairment, and the first signs of this disorder are apparent in infants, before speech has really developed. They exhibits a bizarre disregard for human interaction and, in contrast to a normal child, ignores eye and face contact. Language loss through aging •Alzheimer: Appear to involve both hereditary and environmental factors, the brain deteriorates prematurely, and this loss has profound and ultimately injurious effects on every aspect of a person’s performance. Without Alzheimer With Alzheimer THANK YOU FOR YOUR ATTENTION NEUROLINGUISTICS AND LANGUAGE LOSS The brain is divided in to the left hemispheres and the right hemisphere, and those hemispheres are joined by the corpus callosum THE BRAIN
