First reported in 1907 First reported in 1907 –Shrinkage of cortex –Large masses of amyloid plaques Spherical protein deposits outside of nerve cells Spherical protein deposits outside of nerve cells –Neurofibrillary tangles Twisted protein filaments inside neurons Twisted protein filaments inside neurons –Spread from bottom (midbrain) to top (cortex)

16. Plaques, tangles present in normal aging brain Plaques, tangles present in normal aging brain In Alzheimer’s: excessive, interfere with communication between neurons In Alzheimer’s: excessive, interfere with communication between neurons
