Alzheimer's Disease Alzheimer's Disease : Pathogenic

Abundant neurofibrillary tangles and amyloid plaques throughout the neocortex; Occasional plaques in the spinal cord; Lewy bodies were observed in the substantia nigra and cortex; Moderate to severe amyloid angiopathy in leptomeningeal, cerebral, and cerebellar vessels.

Increased Aβ42/Aβ40 ratio; increased Aβ42; decreased Aβ40.
