Well not exactly, but the headline was attention-grabbing, no? Dementia and other brain-related illnesses can be exacerbated by diabetes and obesity.

An expert on Alzheimer's disease at Johns Hopkins University in Baltimore says "when it comes to keeping the brain healthy, adding extra pounds may be a double-edged sword. It's not only a risk factor for developing Type 2 diabetes, but also a trigger for Alzheimer's disease."Researchers in Chicago studied 842 older Catholic nuns, priests and brothers who had diabetes. None had any sign of Alzheimer's disease at the start, but nine years later, 151 had developed this disease. Another study in the Archives of Neurology in 2004 claimed those with Type 2 diabetes had a 65 percent greater chance of developing Alzheimer's disease. Type 2 diabetes increases this risk because excess weight causes not only diabetes, but also insulin resistance.

Speaking from experience, I can tell if my blood sugar is too high I cannot think as clearly or as quickly. On the flipside, if my blood sugar is too low-I have been known to become nonsensical, directing primitive attacks at inanimate objects (and sometimes the occasional family member). So it would make a world of sense that diabetes can affect brain function, leading to brain-related illnesses. Food for thought.
