PSYB65- Lecture 10  Alexia is a deficit in reading; agraphia is a problem in writing  There are three major categories of aphasia: receptive aphasias- deal with receiving and understanding language/decoding; integrative aphasias- these involve problems in comprehension and formation of language; expressive aphasias- problems in expressing language or problems in getting language out  Can you obey instructions? Can you identify an object? Can you read, write, speak?  Receptive aphasias: Pure word deafness involves problems in relating incoming sounds into representations which allow the understanding of discourse; meaning the person can hear the sounds but cannot distinguish language; quote from a patient, “voice comes, but no words. I can hear, sounds come, but words don’t separate. There is no trouble at all with sound. Sounds come, I can hear, but I cannot understand it.”; these patients have a normal ability to read, write, or speak; cannot understand themselves when they hear themselves speak  Integrative aphasias are problems in selecting and arranging meaningful units and their eventual conversion into comprehensible, coherent speech; so basically these are about the nuts and bolts of speech and being able to truly comprehend/integrate what speech means:  Wernicke’s aphasia (sometimes referred to as jargon aphasia)- speak with unintelligible statements; severity is dependent on the size and location of the damage; often times, they will chatter for long periods of time without making any sense whatsoever; rhythm of language is still intact; in really extreme cases, they might not use real or recognizable words; in terms of naming, they usually cannot name objects very well; but in milder cases, they are usually close (describe it); sometimes they use jargon, something that sounds similar or something that is similar; generally do not understand that they have lost language, so not depressed; they do use objects and utensils correctly/normally; in terms of commands, they respond poorly to commands; they cannot repeat (except a few words that are very well rehearsed); intellect is usually down (IQ test); they can sing just fine except that they may insert parts into the song that don’t belong there; there is very little evidence of the ability to read and comprehend any language (they can read aloud quite well, but will not comprehend it); they write the same gibberish that they would speak  Nominal aphasia (sometimes referred to as anomia); if you show them an object, they cannot name it; the damage is typically in the angular gyrus; they also engage in what is called circumlocution which is talking around something with things that relate to the subject; it is not just
