Symptoms & Causes
Read a list of common symptoms and potential causes of PPA.
Adults of any age can develop primary progressive aphasia (PPA), but it is more common in people under the age of 65. Individuals with PPA may have difficulties in word-finding, word usage, word order, word comprehension or word spelling. Other thinking skills (including memory for recent events, spatial orientation, recognizing faces and the essential features of personality) are initially preserved. The symptoms of PPA can cause limitations in professional, social and recreational activities that may affect one's overall quality of life.
PPA is caused by a neurodegenerative brain disease. Aphasias (language impairment) caused by head trauma, stroke or brain tumor do not qualify for a PPA diagnosis. PPA is diagnosed only if the underlying cause is a "neurodegenerative" disease that progresses over time.
