Type 2 Diabetes May Be Bad for Brain Health
Excess weight appears to amplify the threat, study says
THURSDAY, April 27, 2017 (HealthDay News) -- Previous research has linked type 2 diabetes and memory loss. Now, new research may be closing in on some of the reasons why.
The study found that people with type 2 diabetes -- particularly those who are overweight or obese -- have thinner gray matter in several areas of the brain.
These brain regions are related to memory, executive function, movement generation and visual information processing, said the study's senior author, Dr. In Kyoon Lyoo. He's director of the Ewha University Brain Institute in Seoul, South Korea.
"Obesity leads to increased risk of type 2 diabetes, metabolic dysfunction and is also associated with brain alterations independently," Lyoo said. "We aimed to investigate whether overweight/obesity influenced brain structure and cognitive function in individuals with early stage of type 2 diabetes."
The study included: 50 overweight or obese people with type 2 diabetes; 50 normal-weight people with type 2 diabetes, and 50 normal-weight people without diabetes.
The Korean study volunteers were between 30 and 60 years old. Those with diabetes had it for five years or less, and they were attempting lifestyle modifications and/or taking oral medication to lower blood sugar levels. No one was taking insulin.
The normal-weight group with type 2 diabetes had slightly better blood sugar control -- a hemoglobin A1C level of 7 percent. The overweight folks with type 2 diabetes had hemoglobin A1C levels of 7.3 percent.
Hemoglobin A1C is a two- to Continue reading
