aphasia [ah-fa´zhah]

a type of speech disorder consisting of a defect or loss of the power of expression by speech, writing, or signs, or of comprehension of spoken or written language, due to disease or injury of the brain centers, such as after stroke syndrome on the left side.

Patient Care. Aphasia is a complex phenomenon manifested in numerous ways. The recovery period is often very long, even months or years. Because communication is such a vital part of everyday living, loss of the ability to communicate with words, whether in speaking or writing, can profoundly affect the personality and behavior of a patient. Although aphasic persons usually require extensive treatment by specially trained speech patholigists or therapists, all persons concerned with the care of the patient should practice techniques that will help minimize frustration and improve communication with such patients.

amnestic aphasia anomic aphasia.

anomic aphasia inability to name objects, qualities, or conditions. Called also amnestic or nominal aphasia.

ataxic aphasia expressive aphasia.

auditory aphasia loss of ability to comprehend spoken language. Called also word deafness.

Broca's aphasia motor aphasia.

conduction aphasia aphasia due to a lesion of the pathway between the sensory and motor speech centers.

expressive aphasia motor aphasia.

fluent aphasia that in which speech is well articulated (usually 200 or more words per minute) and grammatically correct but is lacking in content and meaning.

motor aphasia aphasia in which there is impairment of the ability to speak and write, owing to a lesion in the insula and surrounding operculum including Broca's motor speech area. The patient understands written and spoken words but has difficulty uttering the words. See also receptive aphasia. Called also logaphasia and Broca's, expressive, or nonfluent aphasia.

nominal aphasia anomic aphasia.

nonfluent aphasia motor aphasia.

receptive aphasia inability to understand written, spoken, or tactile speech symbols, due to disease of the auditory and visual word centers, as in word blindness. See also motor aphasia. Called also logamnesia and sensory or Wernicke's aphasia.
