What is Frontotemporal Degeneration (FTD)?
Frontotemporal degeneration is a rare type of dementia, as per National Institute on Aging (NIA). According to Mayo Clinic, this affects the brain's frontal and temporal lobes. “These areas of the brain are associated with personality, behavior and language,” the clinic noted.
They may act in ways that seem socially inappropriate, be impulsive or show less responsiveness to other people's feelings. Some even lose the ability to use or understand language. Although it often begins between the ages of 40 and 65, Mayo Clinic noted that it can occur at later stages in life as well.
