Abstrakt: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by neurofibrillary tangles (NFTs), senile plaques from Aβ deposits, neuronal inflammation, oxidative stress, and impaired neuronal transmission involving acetylcholine and glutamate. Diabetes patients are at a higher risk of developing AD-like pathology due to shared pathological and molecular mechanisms, including insulin resistance, oxidative stress, formation of advanced glycation end products (AGEs), and overactive immune systems. Current treatments of AD typically address only one aspect of the disease, rather than treating it as a multifactorial process. Targeting cerebral glucose-insulin metabolism has emerged as a promising strategy for AD management. Numerous studies show positive correlations between anti-diabetic drugs and AD management. Among these, DPP IV inhibitors have demonstrated significant therapeutic benefits against AD in experimental settings. DPP IV inhibitors have been shown to significantly reduce Aβ oligomerization, phosphorylated tau (p-tau), oxidative stress, and inflammatory markers, presenting a potentially effective approach for targeting AD-like pathology. Although preclinical data are promising, clinical trials are needed to validate these findings and establish the safety and efficacy of DPP IV inhibitors as a therapeutic intervention for AD. This could represent a novel approach for addressing both the metabolic and neurodegenerative aspects of AD.
