Summary Summary

Frontotemporal dementias (FTDs) are a group of neurodegenerative disorders associated with shrinking of the frontal and temporal anterior lobes of the brain.^[1] Symptoms include marked changes in social behavior and personality, and/or problems with language. People with behavior changes may have disinhibition (with socially inappropriate behavior), apathy and loss of empathy, hyperorality (eating excessive amounts of food or attempting to consume inedible things), agitation, compulsive behavior, and various other changes.^[1]^[2] Examples of problems with language include difficulty speaking or understanding speech.^[1] Some people with FTD also develop a motor syndrome such as parkinsonism or motor neuron disease (which may be associated with various additional symptoms).^[2]

There is a strong genetic component to FTDs.^[1]^[2] It sometimes follows an autosomal dominant inheritance pattern, or sometimes there is a general family history of dementia or psychiatric disorders.^[2] The three main genes responsible for familial FTD are MAPT, GRN, and C9orf72. However, the genetic cause of familial FTD cannot always be identified.^[2]

While there are currently no treatments to slow or stop the progression of the disease, some of the symptoms can be managed.^[3] Treatment of symptoms may involve behavior modification, or medications for symptoms such as aggressiveness, agitation, or dangerous behaviors. Anti-depressants have been shown to improve some symptoms.^[1] Involving a team of specialists can help ensure that the challenges of the disease are properly addressed.^[3] Unfortunately, the outlook for people with FTD is poor, as the disease often progresses rapidly. However, the outlook does vary, with the disease course ranging from less than 2 years in some people, to more than 10 years in others.^[1]

Although the name and classification of FTD has been a topic of discussion for over a century, the current classification considers Pick’s disease, primary progressive aphasia, and semantic dementia as sub-types of FTD.^[1]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
Orphanet lists international laboratories offering diagnostic testing for this condition.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.
