Frontotemporal dementia is particularly notable for its association with significant personality changes. This form of dementia primarily affects the frontal and temporal lobes of the brain, which are regions involved in regulating behavior, personality, and social functioning. Individuals with frontotemporal dementia may exhibit a range of behavioral changes, including apathy, impulsivity, social withdrawal, and inappropriate social conduct. The distinct changes in personality and behavior are often some of the earliest symptoms observed, setting this type of dementia apart from others where cognitive decline tends to precede or accompany changes in personality.

In contrast, while vascular dementia, Alzheimer's disease, and Lewy-body dementia can also include some degree of personality change, these changes are usually not as pronounced or defining as those seen in frontotemporal dementia. Vascular dementia is often characterized more by cognitive deficits and issues with executive function. Alzheimer's disease primarily presents with memory impairment and cognitive decline, and Lewy-body dementia is marked by fluctuations in cognition, visual hallucinations, and motor symptoms, with any personality changes being secondary to these other more prominent features. Thus, frontotemporal dementia stands out as the type most commonly associated with noticeable and early shifts in personality.
