People with primary progressive aphasia may become mute and may eventually lose the ability to understand written and spoken language.

As the disease progresses, other mental skills, such as memory, may become impaired. Some people may develop other neurological conditions over time. If these complications occur, the affected person eventually will need help with day-to-day care.

People with primary progressive aphasia may also develop behavioral or social problems, such as being anxious or irritable. Other problems may include blunted emotions, poor judgment or inappropriate social behavior.
