Frontotemporal dementia is not life-threatening. A person may live with frontotemporal dementia for years.
Pneumonia is the most common cause of death in those who have frontotemporal dementia. They also are at increased risk for infections and fall-related injuries.
As frontotemporal dementia progressively worsens, a person may engage in dangerous behaviors or be unable to care for himself or herself. A person with frontotemporal dementia may need 24-hour nursing care or to stay in an assisted living facility or nursing home.
