The language and communication impairments that individuals experience following damage to the cerebral cortex vary widely, depending on the extent of involvement and location in the left or right hemisphere. Historically, numerous aphasia syndromes have been described, typically following left hemisphere damage, each with unique characteristics. Other subtle aspects of communication are disrupted in right hemisphere disorders as well. Clinicians who work with individuals with communication disorders recognize patterns of symptoms, administer appropriate assessments, and develop interventions to address the language and communication impairments. Recognized authors from around the world review the extensive literature on the varied aphasia syndromes, acquired dyslexia and dysgraphia, and right hemisphere communication disorders.
