Insulin resistance promotes the development of Alzheimer's disease pathology through multiple interconnected mechanisms including reduced cerebral glucose metabolism, impaired amyloid-beta clearance via competition for insulin-degrading enzyme (IDE), and increased amylin deposition.
Maintaining metabolic health, specifically insulin sensitivity, is a critical strategy for reducing Alzheimer's risk. This involves managing blood sugar, avoiding excessive refined carbohydrates, and engaging in regular physical activity to improve insulin signaling. For those with existing insulin resistance or type 2 diabetes, aggressive management of these conditions may help protect brain health.
This association may in part be due to the systemic mitochondrial dysfunction that is common to these pathologies... Accumulating evidence suggests that mitochondrial dysfunction is a significant feature of AD and may play a fundamental role in its pathogenesis.
Why this rating
The paper is a review citing multiple human and animal studies, but it is not a primary clinical trial.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
