Frontal lobe dementia is associated with deterioration of the amygdala and frontal lobes and is also called frontotemporal lobar degeneration. Which dementia term does this describe?

• A. Lewy body dementia
• B. Alzheimer disease
• C. Vascular dementia
• D. Frontal lobe dementia

Answer: (D)

Deterioration of the amygdala and frontal lobes points to frontotemporal degeneration, known clinically as frontal lobe dementia. This pattern targets the frontal and temporal regions, so early signs are behavioral changes, personality shifts, and language difficulties rather than the prominent memory loss seen in Alzheimer disease. That’s why this term fits best: it names the specific brain areas affected and the resulting behavioral-linguistic symptom profile. In contrast, Lewy body dementia often includes visual hallucinations and fluctuations; Alzheimer disease centers on memory decline with hippocampal and cortical pathology; vascular dementia stems from cerebrovascular disease with a stepwise course and focal neurological signs.
