<prompt> All of the following are true in motor aphasia, EXCEPTImpaired namingImpaired repetitionImpaired fluencyPreserved comprehension  <response>: B Impaired repetition APHASIA is an acquired disorder of language due to brain damage. It does not include developmental disorders of language or speech disorders that are limited to the motor apparatus of speech dysarthria. Related disorders include alexia disorder of reading, agraphia disorder of writing, and apraxia disorder of skilled movements. Transcortical Motor Aphasia TMA results from an injury to the anterior superior frontal lobe. The injury is typically caused by a cerebrovascular accident CVA, commonly referred to as a stroke. The area of insult is sometimes referred to as a watershed region, a region surrounding Brocas area. The insult typically involves the left hemisphere as most people regardless of handed-ness are left hemisphere dominant for language nearly 100 of right-handers, about 85 of left-handers. Characteristics: TMA is a less common impairment than Brocas aphasia. People with TMA generally have good comprehension since Wernickes area is usually not affected. People with TMA experience non-fluent halting and effortful speech due to frontal lobe damage and their utterances are typically only one or two words long. People with TMA retain the ability to repeat words, phrases or sentences. Repetition is preserved since the arcuate fasciculus the neural pathway that connects Wernickes and Brocas areas via the parietal lobe is intact. Preserved repetition is a defining quality of all transcortical aphasias. People who suffer from transcortical motor aphasia, however, may experience delays in initiation when they try to repeat words due to damage in the frontal lobe.
