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.
