medical Definition of frontotemporal dementia
- Alzheimer disease is the most common cause of dementia, but similar impairment of intellectual functioning occurs with many other brain disorders, such as frontotemporal dementia (FTD). After AD, FTD is the second most prevalent cause of early-onset dementia (occurring before age 65 years).
