How is behavioral variant frontotemporal dementia (bvFTD) best described?

• A. A type of dementia characterized by changes in personality and behavior.
• B. A memory-dominant form with early language sparing.
• C. A vascular dementia caused by blood clots.
• D. A type of dementia primarily affecting motor coordination.

Answer: (A)

Behavioral variant frontotemporal dementia presents mainly with personality and behavioral changes due to degeneration in the frontal and temporal brain regions. People often become socially inappropriate, impulsive, apathetic, emotionally flat, or show loss of empathy and compulsive behaviors. Memory can be relatively intact early on, which helps distinguish it from memory-centered dementias. Over time, executive function and language may decline, but the defining feature is these early behavioral and personality shifts. This makes it the best description for bvFTD, rather than a memory-dominant profile (as seen in typical Alzheimer's disease), vascular dementia from strokes, or a motor-dominant dementia that chiefly impairs movement and coordination.
