Why does dementia always start in the memory center of the brain?

Answer 1

Alzheimer’s dementia usually starts with memory loss and it’s the most common type of dementia, but other types of dementia do not typically start with memory loss. Lewy body dementia tends to start with impairments in attention and executive function, and possibly visual hallucinations. Frontotemporal dementia usually starts with personality/behavioral changes.
