: Where in the brain is dementia located?

I volunteer in a brain-injury lab and when mice are brain damaged, they develop the abeta protein (associated with Alzheimer's) AT THE SITE where they were brain damaged. As far as people that get Alzheimer's due to genetics, I don't know about that. I would suspect that if someone had a brain injury (such as a stroke, bleed, blunt force to the head....) that was severe enough to cause dementia (which gives the same type of symptoms as Alzheimer's), then they would experience cell damage at the site of injury. The problem with this is that it can be a progressive disease (in other words, it gets worse over time).
