Alzheimer's Disease Alzheimer's Disease : Pathogenic

Neuropathology consistent with AD, including abundant amyloid plaques and severe neurofibrillary tangle pathology (stage VI Braak and Braak). Amyloid deposits were comprised largely of Aβ42, with little to no Aβ40. There was minimal amyloid angiopathy in vessels.

Increased Aβ42.
