To evaluate the temporal progression of cortical cholinergic denervation in Alzheimer's disease and determine its contribution to clinical deficits and underlying neuropathology.
Synthesized existing neuropathological and clinical evidence assessing cortical cholinergic innervation across various stages of Alzheimer's disease.
Evaluated relationships between cholinergic pathway disruption, cognitive-behavioral symptoms, and disease mechanisms including amyloidogenesis, tau phosphorylation, and neuroplasticity.
Cholinergic innervation perturbations occur during the very early stages of Alzheimer's disease rather than exclusively in late stages.
Cholinergic deficits are not the primary driver of overall neuropathology but significantly aggravate the severity of memory and attentional impairments.
Loss of cholinergic input modulates disease progression through downstream interactions with amyloid accumulation, tau phosphorylation, and impaired neuroplasticity.
