• Stepwise cognitive decline
• Impaired visual-spatial coordination
• Motor symptoms of parkinsonism
• Impaired speech and language skills

  The correct answer is: Impaired speech and language skills   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:

1. 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.
2. 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.
