People with diabetes are more prone to anxiety and depression than those with other chronic diseases that require similar levels of management. The reasons for this aren't well understood, but Joslin Diabetes Center researchers have discovered one potential explanation.Pretty, pretty, pretty.
Genetically modifying mice to make their brains resistant to insulin, the Joslin scientists first found that the animals exhibited behaviors that suggest anxiety and depression, and then pinpointed a mechanism that lowers levels of the key neurotransmitter dopamine in areas of the brain associated with those conditions.
"This is one of the first studies that directly shows that insulin resistance in the brain actually can produce a behavioral change."
Makes a nice follow up to the previous post, huh?
