Neurobiological links between Alzheimer's disease and reward system dysfunction

1 month 2 weeks ago
Alzheimer's disease (AD) is a highly prevalent progressive neurodegenerative disorder with unclear etiology, complex symptoms, and limited treatment options. Early pathological processes in AD emerge long before the onset of overt cognitive and motor symptoms and involve the accumulation of amyloid-β oligomers and neurofibrillary tangles, accompanied by neuroinflammation and neuronal loss. Importantly, the brain reward system comprises cortical and subcortical structures that share neurochemical...
