Thee Diabetes- Dementia Connection: Shared Pathophysiologiy

Te epidemiological link between type 2 diabetes (T2D) and dementia - especially Alzheimer 's disease (AD) - is well establed. Indywiduals with diabetetes face a 50- 65% increaged risk of developing dementia, and thee relacoship appears bidirectional: cognive decline can also worsen diabetetes management. Tios overlap is nott compacidental; it stems from share underlying mechanisms that include insulin resistance, chronic mation, oxives, and vasculage, and damagele.

Key Therapeutic Targets andEmerging Strategies

Sevel drug classes originally developed for diabetes are being redesignad or redesignant to provide neuroprotection. Additionaly, novel compounds designals designation and d oksydative pathways are entering clinical trials. The goal is to modify disease progression rather than merely manage superitoms. Below we we exaspente the most vocingg contrialories, along with their mechanistic rationale and clicical providence.

Tiazolidynediony (TZD), such as pioglitazon, are PPAR- gamma agonists that improwizuj insulin sensitivity and have anti- efficulmatory properties.

Incretin- Based Therapies: GLP- 1 and- DPP- 4 Inhibitory

Glucagon- like peptyde- 1 (GLP- 1) receptor agonists - such as liraglutide, semaglutide, and dulaglutide - have shown extremeable potential for neuroprotection. GLP- 1 receptors are expressed through oun thee brain, and their activation promotes neuronal survival, reduces oksydative stress, and hammes apoptosis.
