Also known as Frontotemporal Disorders and Behavioral Variant Temporal Dementia, or bvFTD.
Frontotemporal Dementia is a decline in thinking caused by brain changes in the frontal and temporal lobes of the brain. As FTD causes neurons in these areas of the brain to die, these lobes decay. Many different symptoms occurs as the lobes decay, including changes in behavior, emotional problems, language and communication issues, difficulty with making decisions, and difficulty with physical movements.
Researchers estimate FTD may cause more than ten percent of all cases of dementia. After early-onset Alzheimer’s disease, it is the second most common cause of dementia in people younger than age 65. Roughly 60 percent of people diagnosed with FTD are 45 to 64 years old.
While some people diagnosed with FTD experience rapid changes over two to three years, other people experience slower changes. In early stages, people may have just one type of symptom. But as the disease progresses, other types of symptoms may appear. The symptoms that appear are connected to the part of the brain affected by FTD.
