Molecular Connection Between Diabetes and Dementia.

Area of Science:

• Neuroscience
• Endocrinology
• Metabolic Diseases

Background:

• Type 2 diabetes mellitus (T2DM) and Alzheimer's disease (AD) are prevalent global health issues.
• Both diseases share common risk factors, age-related onset, and pathological features.
• Key shared features include insulin resistance, impaired glucose metabolism, and chronic inflammation.

Purpose of the Study:

• To review and discuss the molecular links between T2DM and AD.
• To explore how shared mechanisms contribute to the pathogenesis of both diseases.
• To provide insights for developing novel therapeutic strategies.

Main Methods:

• Literature review of research on T2DM and AD.
• Analysis of shared molecular pathways and risk factors.
• Discussion of deregulation of O-GlcNAcylation as a potential molecular link.

Main Results:

• Identified insulin resistance, impaired glucose metabolism, and O-GlcNAcylation deregulation as key molecular links.
• Highlighted commonalities in chronic oxidative stress and inflammation.
• Emphasized the interconnectedness of metabolic and neurodegenerative processes.

Conclusions:

• Shared molecular mechanisms provide a basis for understanding the co-occurrence of T2DM and AD.
• Targeting these common pathways may offer a dual therapeutic approach.
• Further research into these links is essential for effective disease prevention and treatment.
