Aphasia: Classification of the Syndromes

1. Aphasia: Classification of the Syndromes

2. Aphasia:�--------------�Aphasia is the loss of the ability to understand or produce speech, because of the brain damage. Language deficits required after brain injury are called (aphasia).��During a collision ,the brain can be smashed against the skull with enough force to create a closed head injury, or something might strike the skull ,or problem could originate inside the skull with infection,tumor,or broken blood vessels damaging brain tissues.��The patient can not speak more than a few words or syllables ,understands very little .When this type of deficit persists it is referred to as a global aphasia.�� ��

3. 1-Broca s Aphasia: �The classic Brocas Aphasic in today's taxonomy is considered non-fluent in that his speech is slow, deliberate, and effortful often with the omission of grammatical markers. �The patient L.M was a sixty-year-old man who had a stroke which damaged a large portion of his left hemisphere, leaving him paralyzed on his right side .He experienced a number of language problems including some problems with naming and repetition. �

4. 2-Wernikes Aphasia:�Carl Wernicke presented information on two patients whose speech was markedly different from that of Brocas patient.�� Their speech was relatively fluent �that is, the intonation and pace appeared normal, but it contained un semantic features. The patient would use elaborate descriptions, called Circumlocution ,instead of simple words.�

5. Conclusion:�The different aphasia syndromes are linked to damage in different areas of the central left hemisphere .Problems in coming up with specific lexical items arise with mild damage any where. Problem with producing the sounds of language correctly and in generating syntactic strings of words are associated predominantly anterior lesions including Brocas area. Problems with comprehension and empty speech are associated with damage to posterior regions around wernickas area.
