What is the typical early clinical presentation of frontotemporal dementia?

• A. Early language impairment only
• B. Early visuospatial deficits
• C. Prominent behavioral and personality changes with relatively spared memory in the early stages; dysexecutive symptoms
• D. Early prominent memory decline

Answer: (C)

Frontotemporal dementia most often begins with changes in behavior, personality, and executive control rather than with memory problems. The early signs are things like disinhibition, apathy, loss of empathy, and trouble planning or organizing daily activities, and memory remains relatively intact at the start. This pattern happens because the disease initially affects the frontal and temporal brain regions that govern behavior and executive function, rather than the memory systems in the hippocampus that are impacted earlier in other dementias. That’s why the described presentation—prominent behavioral and personality changes with relatively spared memory and dysexecutive symptoms—best fits the typical early course of frontotemporal dementia. In contrast, early language-only problems don’t capture the broad behavioral disruption, early visuospatial deficits point toward other syndromes, and early prominent memory decline is more characteristic of Alzheimer's disease.
