Frontotemporal dementia (FTD)

Frontotemporal dementia (FTD) encompasses a range of brain disorders that primarily impact the frontal and temporal lobes, which are crucial for regulating personality, behavior, and language.

In FTD, these brain regions experience shrinkage, known as atrophy, leading to symptoms that vary based on the specific areas affected. Individuals with this condition may exhibit significant changes in personality, including socially inappropriate behavior, impulsivity, or emotional detachment. Alternatively, some may struggle with language use.

FTD is sometimes mistakenly identified as a mental health disorder or confused with Alzheimer's disease. However, FTD typically manifests earlier than Alzheimer's, usually between the ages of 40 and 65, though it can appear later. It accounts for approximately 10% to 20% of dementia cases.
