🧪 Overview

Impaired brain insulin/IGF-1 signaling and reduced glucose metabolism represent metabolic failure across NDDs. However, ALS IGF-1 trials were negative, and AD/PD metabolic associations are heavily confounded by age, vascular disease, and systemic diabetes. Druggability is easy (intranasal insulin, GLP-1 agonists, metformin-like AMPK modulation) but specificity is poor. Best reframed as metabolic biomarker stratification for adjunctive intervention rather than primary cross-disease mechanism.
