Cytopathologic hallmarks of Alzheimer's include:
O Extracellular Beta-amyloid plaques
O Intracellular tangles of hyperphosphorylated Tau
O Aggregated polyglutamine proteins
O Alpha-motor neuron loss
O Both A and B



Answer :

Answer:Both A and B

Cytopathologic hallmarks of Alzheimer's disease include:

Extracellular beta-amyloid plaques: These are deposits of amyloid protein that accumulate outside neurons.

Intracellular tangles of hyperphosphorylated tau: These are twisted fibers that form inside neurons from a protein called tau.
