Type 2 diabetes: Cognitive problems are more present in those with high blood sugar


Glucose is the body’s main source of fuel. The pancreas produces insulin to convert glucose from food into energy. In people with insulin resistance such as those with type 2 diabetes, cells do not respond adequately to insulin, prompting the pancreas to produce more of the hormone. Eventually, the pancreas fails to keep up. Without insulin, sugar levels rise in the bloodstream, which can damage the kidneys and other organs. A growing body of research has pinpointed high blood sugar levels also affecting a person’s brain which could increase their risk of developing dementia or Alzheimer’s disease later in life.

“This should identify which individuals are at increased risk, what are vulnerable periods in life, and what are windows of opportunity for treatment.

“Epidemiological studies have been linked with type 2 diabetes and Alzheimer’s disease and vascular dementia.

“Micro/macro-vascular complications and severe hypoglycaemic increase dementia risk.

“Prevention of vascular damage is key target in the prevention of dementia in type 2 diabetes.

“A lifetime perspective is needed on risk factors for dementia in type 2 diabetes.

Many people with diabetes have brain changes that are hallmarks of both Alzheimer’s disease and vascular dementia, said the Mayo Clinic.

The health site continued: “Some researchers think that each condition fuels the damage caused by the other.

“Diabetes may also increase the risk of developing mild cognitive impairment (MCI), a condition in which people experience more thinking (cognitive) and memory problems than are usually present in normal aging.”

The good news is that by controlling your blood sugar levels by adopting a healthier lifestyle you can not only lower your blood sugar levels to a more normal range but also reduce your risk of dementia and Alzheimer’s disease.
