Living as an autistic human with cPTSD, my personal health journey has always intersected with questions about the brain, stress, and physical illness. Recent neuroscience is finally exposing the depth of mind-body connections in conditions like type 2 diabetes (T2D)—and for people wired differently, like those on the autism spectrum or living with the scars of toxic stress, these findings feel especially urgent. A new mechanism, outlined in Lin et al. (2025), peels back the lid on how metformin, the most common diabetes drug, directly interacts with the brain’s ventromedial hypothalamus (VMH) to control blood sugar. This opens new theories about the unique diabetes risks faced by neurodivergent and trauma-affected populations and whether treatment responses might also diverge.
