Calcium modulates many neural processes, including synaptic plasticity and apoptosis. Dysregulation of intracellular calcium signalling has been implicated in the pathogenesis of Alzheimer's disease. Increased intracellular calcium elicits the characteristic lesions of this disorder, including the accumulation of amyloid-beta, the hyperphosphorylation of TAU and neuronal death. Conversely, neurodegeneration that is induced by amyloid-beta or TAU is probably mediated by changes in calcium homeostasis. Disruption of calcium regulation in the endoplasmic reticulum mediates the most significant signal-transduction cascades that are associated with Alzheimer's disease. Moreover, mutations that cause familial Alzheimer's disease have been linked to intracellular calcium signalling pathways. Destabilization of calcium signalling seems to be central to the pathogenesis of Alzheimer's disease, and targeting this process might be therapeutically beneficial.
