Frontotemporal degeneration (FTD), which refers to a group of progressive neurological diseases affecting the brain’s frontal and temporal lobes, is the most common cause of dementia for people under age 60. The FTD disorders are characterized by gradual deterioration in behavior, personality, language, and/or movement, with memory usually relatively preserved. FTD may also be referred to as frontotemporal dementia, frontotemporal lobar degeneration (FTLD), or Pick’s disease.

Clinical FTD diagnoses include behavioral variant FTD (bvFTD), primary progressive aphasia (PPA), corticobasal syndrome (CBS), progressive supranuclear palsy (PSP), and ALS with FTD. Specific symptoms and the course of disease can vary significantly across individuals, even within the same subtype.

Although age of onset can range from 21 to 80, the majority of FTD cases occur between 45 and 64. The young age of onset substantially increases the impact of the disease on work, relationships, and the economic and social burden faced by families.

FTD is frequently misdiagnosed as Alzheimer’s disease, depression, Parkinson’s disease, or a psychiatric condition. On average, it currently takes 3.6 years to get an accurate diagnosis. There are no cures or disease-modifying treatments for FTD, and the average life expectancy is 7-13 years after the start of symptoms.
