The hallmark of Alzheimer’s disease (AD) is associated with the accumulation of “senile” plaques that are composed of amyloid-beta (Aβ) protein that surround neurons in affected regions. This accumulation results in loss of neurons in the hippocampus and cerebral cortex, leading to progressive cognitive decline such as memory defects. A connection between the brain and…
