Federal government websites often end in. The site is secure. Frontotemporal disorders FTD , sometimes called frontotemporal dementia, are the result of damage to neurons in the frontal and temporal lobes of the brain. Many possible symptoms can result, including unusual behaviors, emotional problems, trouble communicating, difficulty with work, or difficulty with walking. FTD is rare and tends to occur at a younger age than other forms of dementia. FTD is progressive, meaning symptoms get worse over time. In the early stages, people may have just one symptom. As the disease progresses, other symptoms appear as more parts of the brain are affected. It is difficult to predict how long someone with FTD will live. Some people live more than 10 years after diagnosis, while others live less than two years after they are diagnosed. There is currently no cure for FTD, and no treatments slow or stop the progression of the disease, but there are ways to help manage the symptoms. One of the challenges shared by people living with these disorders, families, clinicians, and researchers is what terminology to use. Here, we have used the term frontotemporal disorders to characterize this group of diseases and the abbreviation FTD, which is commonly used to refer to them. Other terms used include frontotemporal lobar degeneration and frontotemporal dementia, but it's important to note that with some frontotemporal disorders, the primary symptoms are problems with speech or movement, rather than dementia symptoms. In the early stages, it can be hard to know which type of FTD a person has because symptoms and the order in which they appear can vary from one person to another.

Frontotemporal dementia FTD , frontotemporal degeneration disease , [1] or frontotemporal neurocognitive disorder [2] encompasses several types of dementia involving the progressive degeneration of the brain's frontal and temporal lobes. Signs and symptoms tend to appear in late adulthood, typically between the ages of 45 and Men and women appear to be equally affected. FTD is the second most prevalent type of early onset dementia after Alzheimer's disease. Currently, there is no cure, but there are treatments that help alleviate symptoms. Each FTD subtype is relatively rare. Two rare distinct subtypes of FTD are neuronal intermediate filament inclusion disease and basophilic inclusion body disease.
