Impaired self-control can be a symptom of type 2 diabetes
A study published in BioPsychoSocial Medicine
reports that type 2 diabetes - a very common disease associated with obesity - may be associated with an inability to resist the temptation of food. The neurological changes that result from poor impulse control may exacerbate diabetes.
According to lead author Hiroaki Kumano, diabetic patients are challenged each day to resist high-fat, high-calorie food and make strict decisions in order to maintain their health.
Japanese researchers from Waseda University examined 27 patients with type 2 diabetes and 27 healthy individuals. To gauge their level of impulse control, the participants underwent a computer test. They were asked to quickly press a button when the correct signal appeared on the screen, which increased their score. However, pressing the button in response to the wrong signal decreased their score.
The study found that type 2 diabetes patients performed significantly worse and struggled more against the impulse to press the button.
"This suggests the possibility that the neuropsychological deficits in response inhibition may contribute to the behavioral problems leading to chronic lifestyle-related diseases, such as type 2 diabetes," said Kumano.
