Diabetes can cause the memory loss of people, researchers found that diabetes and memory loss are closely linked, and poorly controlled diabetes can cause memory loss. The brain runs on glucose and brain glucose storage is limited. To maintain normal brain functioning, people with diabetes need a constant supply of glucose from their blood. Memory loss and reduced brain functioning occur during periods of high blood glucose (hyperglycemia)and low blood glucose (hypoglycemia), so you had better control your blood glucose level normally. Making self-monitoring of blood glucose level by FED blood glucose meter and test strips can give you much help. Both extremes may contribute to the development of memory problems amongst people with type 1 and type 2 diabetes. Diabetes is also linked with depression and alzheimer’s disease. Memory loss caused by poorly controlled blood sugar (glucose related memory loss) is a risk for people with diabetes. How does diabetes affect memory loss? A blood-brain barrier regulates the transport of nutrients, including glucose, into the brain. These nutrients leave the brain as chemically charged particles and by-products of the brain metabolising. If insufficient blood glucose, or too much blood glucose, reaches the blood-brain barrier, memory loss may develop. So avoiding memory loss is simply a matter of keeping blood sugar stable? Good diabetes management (keeping blood sugar stable, testing blood glucose level by FED blood glucose monitoring system regularly, exercising regularly and eating a healthy diet) is the key to avoiding memory loss. However, cortisol, an essential hormone in the body that is strongly linked with diabetes, may also affect memory function. Higher and prolonged levels of cortisol in the bloodstream may affect the brain and cause memory loss
