Document Summary
Aphasia: partial/complete loss of language abilities following brain damage. Poor repetition, poor naming and repeats overlearned utterances, variable reading. Superior surface of temporal lobe between auditory cortex and angular gyrus. Fluent spontaneous speech, but often meaningless, paraphasia common. Conduction aphasia: comprehension is good, speech is fluent. Paraphasia common (literal), repetition and naming impaired, and reading is variable. Anomic aphasia: consistent inability to produce words for things that they want to talk about (particularly nouns and verbs), deficit of expressive language. Damage to various parts of the parietal or temporal lobe caused by a congenital condition or a brain trauma (stroke or tumor) Trans-cortical motor aphasia: i(cid:373)ila(cid:396) to b(cid:396)o(cid:272)a"s (cid:271)ut (cid:449)ith good (cid:396)epetitio(cid:374), la(cid:374)guage output (spontaneous) is non-fluent and there is a reduction in phrase length and simplification of grammatical form. Paraphasia is uncommon, comprehension, repetition and reading are preserved. Commonly results from large dorsolateral frontal lesion extending deep into the white matter.
