Aphasia is common in elderly patients in the context of vascular or neurodegenerative disorders. In some cases, aphasia is an isolated symptom, occurring suddenly after a stroke, or developing progressively as a primary progressive aphasia. The diagnosis and treatment are then very similar in older and younger patients. Therapy may be more complicated because of the high prevalence, in older patients, of associated non linguistic symptoms (attentional and dysexecutive symptoms, behavioral and psychological symptoms or sensorial deficits), fatigability, and comprehension deficits. It may then become very difficult to recognize aphasia among all these disorders and to appreciate the physiopathology. A complete evaluation of language, cognitive functions, psychopathology, and behavior is very helpful, as are neuroimaging techniques (MRI is the most relevant). A good knowledge of classical aphasic pictures associated with stroke, Alzheimer disease or related disorders, is highly recommended. Rehabilitation must be proposed even for older patients, so far as aphasia alters the communication abilities. It must be kept in mind that associated symptoms may limit considerably the therapy.
