Questions about Dad's autopsy

I’ve spent days going through Dad’s autopsy report, and I’m really disappointed.  I don’t think it answers any of the questions we listed on the autopsy request. For example, I thought the autopsy would give a firm diagnosis of Alzheimer’s if Dad's brain had a lot of plaques and tangles .  Tangles aren’t addressed at all in this report, and the two statements about plaques seem contradictory to me.

I’ve sent Dad’s neurologist a list of questions hoping he can answer them.
