This narrative review aims to synthesize and critically evaluate the complex molecular mechanisms by which amyloid-β (Aβ) accumulation disrupts hippocampal synaptic plasticity, the cellular cornerstone of learning and memory in Alzheimer's disease (AD). AD is characterized by progressive hippocampus-dependent cognitive decline, strongly linked to impaired synaptic plasticity, the cellular basis of learning and memory. This review deciphers how Aβ accumulation orchestrates synaptic sabotage in the hippocampus. We detail the core molecular machinery of hippocampal synaptic plasticity, emphasizing glutamate receptor trafficking (NMDAR/AMPAR), Ca Show less
