What is “Fronto Temporal Dementia”, the diagnosis of movie actor, Bruce Willis

Frontotemporal dementia (FTD), also known as frontotemporal degeneration, is a type of dementia that affects the frontal and temporal lobes of the brain. These areas are responsible for controlling behavior, personality, and language, so FTD can cause changes in these areas.


FTD can occur at any age, but it is most commonly diagnosed in people between the ages of 45 and 65. There are three main subtypes of FTD, which are classified based on the symptoms that are most prominent:

  1. Behavioral variant FTD (bvFTD): This subtype is characterized by changes in behavior, personality, and social conduct. People with bvFTD may become more impulsive, apathetic, or socially inappropriate, and they may have difficulty with planning and decision-making.

  2. Semantic dementia: This subtype is characterized by a loss of knowledge of words and objects. People with semantic dementia may have difficulty understanding or using words, and they may have trouble recognizing familiar objects or faces.

  3. Progressive nonfluent aphasia: This subtype is characterized by a gradual loss of the ability to produce language. People with progressive nonfluent aphasia may struggle to find the right words, speak in short sentences, or have difficulty with grammar.

There is currently no cure for FTD, but treatments can help manage symptoms and improve quality of life. Treatment may include medications to manage behavioral symptoms, speech therapy to improve communication, and support from caregivers and family members.
