Document Summary
Language disorders result from region specific brain damage. Broca"s area: a region of the frontal lobe of the brain that is involved in the production of speech: left inferior frontal region. Aphasia: an impairment in language understanding and/or production that is caused by brain injury: damage is in the left cerebral hemisphere. The left hemisphere specialization is confirmed by techniques such as the wada test and by behavioral measures of cerebral asymmetry. Paraphasia: a symptom of aphasia that is distinguished by the substitution of a word by a sound, an incorrect word, an unintended word, or a neologism: neologism: a meaningless word. Conversation is usually fluent or easy to produce. Nonfluent speech: talking with considerable effort, short sentences, and the absence of the usual melodic character of conversational speech. Most patients with aphasia also have trouble with writing and reading: agaphia: the inability to write, alexia: the inability to read.
