Explanation:
Frontotemporal dementia (FTD) is characterized by progressive degeneration of the frontal and temporal lobes, leading to distinct clinical subtypes. The most common early features include:
- Language Deficits (Primary Progressive Aphasia, PPA):
- Nonfluent/agrammatic variant: Halting speech, grammar errors.
- Semantic variant: Loss of word/object meaning.
- Logopenic variant (less common in FTD, more Alzheimer’s-related): Word-finding pauses.
- Behavioral Variant FTD (bvFTD):
- Personality changes (apathy, disinhibition, compulsions).
- Preserved memory early on (vs. Alzheimer’s).
Why Not the Others?
- Stepwise cognitive decline: Suggests vascular dementia.
- Impaired visual-spatial coordination: Seen in Alzheimer’s disease (parietal lobe involvement).
- Parkinsonism: Occurs in FTD with motor neuron disease (FTD-MND) or corticobasal degeneration, but not a hallmark of typical FTD.
Key Insight:
FTD’s early language/behavioral symptoms contrast with Alzheimer’s memory-first presentation. MRI shows focal frontal/temporal atrophy.
Thus, impaired speech/language is the most characteristic feature.
