Guest Author, Robert Best, Executive Director Oak Hill Terrace discusses Frontotemporal Dementia in Part I of a series on dementias.
As our population ages, more of us will experience the impact of Alzheimer’s. There is a very good chance that someone in your own family or a friend has a loved one diagnosed with Alzheimer’s or dementia. The label “Alzheimer’s disease,” once thought to be a rare form of early dementia, has become so common that most people use the terms “Alzheimer’s disease” and “dementia” interchangeably. In reality, dementia is an umbrella term for a diverse group of disorders that cause the loss of memory and other intellectual abilities. Alzheimer’s disease is believed to be the most common form of dementia, accounting for possibly 50 to 70 percent of all cases. However, as researchers have learned to distinguish the types of dementia and as testing methods have improved, we are beginning to see more precise diagnosis. It is advantageous to distinguish between the many types of dementia, as they respond differently to treatments.
Frontotemporal dementia (FTD), once called Pick’s Disease, is also an umbrella term for a number of disorders that primarily affect the frontal and temporal lobes of the brain — the areas generally associated with personality, behavior, memory and language. FTD is rare but the onset can occur in people as young as 20, but usually begins between ages 40 and 60. The average age at which it begins is 54. In this disease portions of the frontal and temporal lobes atrophy or shrink, resulting in damage to the brain. (The New York Times published a very moving story about one couple’s story with FTD on May 5th. When Illness Makes a Spouse a Stranger.)
