Diabetes can Cause Brain Disease

It has been proved in clinical research that inadequate insulin or hyperinsulinemia will cause bad damage to the cognitive function from different aspects.


Inadequate insulin will cause high blood glucose level. Long-term Chronic High Blood Glucose Level will make the capillary basement membrane thicken, leading to narrow capillary cavity. Plus the metabolic disorder of fat, blood viscosity state will become more serious, and blood speed will slow down, the blood flow in the brain will reduce. It’s found in study that if the blood flow in the brain reduces, the process of brain identifying, organizing and ordering information will be badly affected, little by little, the response ability and handling ability will degrade, at last, patients will find the damage to their cognitive function. There is no doubt that high blood glucose level will accelerate the onset of senile dementia.


Hyperinsulinemia is one of the typical symptoms in Type 2 Diabetes. In Type 2 Diabetes, those patients who have Hyperinsulinemia or depend on insulin injection often suffer from low blood glucose. If blood glucose level declines, a series of response will occur due to severe fluctuation of blood glucose levels. when blood glucose level is lower than 3.0 mmol/l, there will be damage to the cognitive function. Besides, low spirit will be caused due to low blood glucose level, such as anxiety, depression and the fear to the low glucose level. Such low spirit will affect the control of blood glucose level. The reoccurrence of low glucose level will aggravate the damage to the cognitive function.
