Introduction
Few people have heard of frontotemporal disorders, which lead to dementias that affect personality, behavior, language, and movement. These disorders are little known outside the circles of researchers, clinicians, patients, and caregivers who study and live with them. Although frontotemporal disorders remain puzzling in many ways, researchers are finding new clues that will help them solve this medical mystery and better understand other common dementias.
The symptoms of frontotemporal disorders gradually rob people of basic abilities—thinking, talking, walking, and socializing—that most of us take for granted. They often strike people in the prime of life, when they are working and raising families. Families suffer, too, as they struggle to cope with the person’s daily needs as well as changes in relationships and responsibilities.
This booklet is meant to help people with frontotemporal disorders, their families, and caregivers learn more about these conditions and resources for coping. It explains what is known about the different types of disorders and how they are diagnosed. Most importantly, it describes how to treat and manage these difficult conditions, with practical advice for caregivers.

The Basics of Frontotemporal Disorders
Frontotemporal disorders are the result of damage to neurons (nerve cells) in parts of the brain called the frontal and temporal lobes. As neurons die in the frontal and temporal regions, these lobes atrophy, or shrink. Gradually, this damage causes difficulties in thinking and behaviors normally controlled by these parts of the brain. Many possible symptoms can result, including unusual behaviors, emotional problems, trouble communicating, difficulty with work, or difficulty with walking.
A Form of Dementia
Frontotemporal disorders are forms of dementia caused by a family of brain diseases known as frontotemporal lobar degeneration (FTLD). Dementia is a severe loss of thinking abilities that interferes with a person’s ability to perform daily activities such as working, driving, and preparing meals. Other brain diseases that can cause dementia include Alzheimer’s disease and multiple strokes. Scientists estimate that FTLD may cause up to 10 percent of all cases of dementia and may be about as common as Alzheimer’s among people younger than age 65. Roughly 60 percent of people with FTLD are 45 to 64 years old.
People can live with frontotemporal disorders for up to 10 years, sometimes longer, but it is difficult to predict the time course for an individual patient. The disorders are progressive, meaning symptoms get worse over time. In the early stages, people may have just one type of symptom. As the disease progresses, other types of symptoms appear as more parts of the brain are affected.
No cure or treatments that slow or stop the progression of frontotemporal disorders are available today. However, research is improving awareness and understanding of these challenging conditions. This progress is opening doors to better diagnosis, improved care, and, eventually, new treatments.
