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.

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.

Two predictions follow from the 4-M model: (1) some functional elements or closed-class items will occur in agrammatic aphasia simply because they are content morphemes under the 4-M model, such as personal pronouns in English; (2) the division of [+/- conceptually activated] in the 4-M model will mean that early system morphemes should pattern more like content morphemes and, therefore, be more accurate than either of the other two classes of system morphemes.
Whey compare the production of the French definite articles le and la with the homophonous object pronominal clitics in agrammatic aphasia. In terms of the 4-M model, French articles are early system morphemes, indirectly elected by the gender and number features of their noun.
