Progressive dementia with symptoms of executive dysfunction, personality change, and motor weakness leads to severe morbidity. Death usually occurs within 3 years of onset from inanition, pulmonary failure, and aspiration.

Patients with FTD/MND generally follow a more rapid course than do patients with either FTD or MND alone. They are more likely to have a bulbar form of MND, which may help to explain its more aggressive course.
