Type 2 diabetes is linked with the reduction of certain cognitive abilities, known as executive functions, revealed a study led by University Of Waterloo. Researchers explained that the executive functions inhibit habitual thinking patterns, knee-jerk emotional reactions and reflexive behaviors such as making impulse purchases or automatically following social cues.
Lead author of the study, Corrie Vincent, said, "Cognition was an integral part of brains because people rely on it when they are attempting to behave in a way that was contrary to their natural inclinations or what the environment impels them to do."
The study showed that people with type 2 diabetes experience burnout in managing their disease. This inability of self-management was often a source of concern among family members, physicians and even the patients themselves. Senior author of the study, Peter Hall, explained, "The problem was the fact that effective diabetes management relies pretty heavily on executive function, and people with this disease especially requires more executive control, but because of the disease's effect on the brain there are less intact resources for exerting it."
The study appears in Psychosomatic Medicine.
