Okay, the user provided a question about FTD (Frontotemporal Dementia) asking which statement is not true. The correct answer is missing, but I need to figure out the correct answer based on the options. Since the options are not listed, I'll have to think about common misconceptions or incorrect statements related to FTD.

First, let's recall the core concepts of FTD. Frontotemporal dementia is a group of disorders caused by progressive nerve cell loss in the brain's frontal and temporal lobes. It's characterized by changes in personality, behavior, and language. Common features include early behavioral changes, executive dysfunction, and preservation of memory in early stages.

Now, typical incorrect statements might be:
- Suggesting memory loss is the primary early symptom (but in FTD, memory is usually preserved until later stages).
- Associating with Lewy bodies (FTD is associated with tau or TDP-43 proteins, not Lewy bodies which are for PD/DLB).
- Mentioning that it's the most common form of dementia (Alzheimer's is more common).
- Suggesting that it's always hereditary (only about 10-30% have a family history).

So, if one of the options states that memory impairment is the earliest feature, that's the incorrect one. Another wrong option could be that it's associated with amyloid plaques, which are characteristic of Alzheimer's, not FTD.

I need to structure the explanation with the required sections. The core concept should explain FTD's pathology and clinical features. The correct answer explanation would highlight the incorrect statement, perhaps about memory being early. Then each wrong option would be addressed, explaining why they're incorrect. The clinical pearl might emphasize distinguishing FTD from Alzheimer's based on early symptoms.

I should make sure the sections are clearly labeled and the explanations are concise but thorough. Also, check that the clinical pearl is a high-yield fact, like the difference in symptoms between FTD and Alzheimer's. Finally, end with the correct answer line once the correct option is determined.

**Core Concept**
Frontotemporal dementia (FTD) is a neurodegenerative disorder characterized by atrophy of the frontal and temporal lobes, leading to behavioral, emotional, and language disturbances. Unlike Alzheimer’s disease, memory impairment is not an early feature; instead, executive dysfunction and personality changes dominate.

**Why the Correct Answer is Right**
The incorrect statement would likely be that **memory loss is a hallmark of early FTD**. FTD typically spares memory in its initial stages. Instead, patients exhibit apathy, disinhibition, or progressive language deficits (e.g., semantic dementia or progressive nonfluent aphasia). Pathologically, FTD is linked to tau or TDP-43 proteinopathies, not amyloid-beta plaques seen in Alzheimer’s.

**Why Each Wrong Option is Incorrect**
**Option A:** *If it claims "FTD is associated with Lewy bodies"*, this is incorrect—Lewy bodies are hallmark of Parkinson’s disease/dementia with Lewy bodies.
**Option B:** *If it states "FTD is the most common form of early-onset dementia"*, this is false—Alzheimer’s remains the most common.
**Option C:** *If it suggests "MRI shows parietal lobe atrophy"*, this is
