High Blood Sugar Could Impair Memory As You Age

High Blood Sugar Could Impair Memory As You Age

A new study links high blood sugar levels to poor memory in the elderly. People looking to maintain their memory as they age should start making better health decisions now. According to a new study published in the journal Neurology, people with high blood sugar levels may develop memory problems as they get older.Aug 20, 2018

Can high blood sugar levels cause memory loss?

Uncontrolled diabetes may increase the risk of experiencing cognitive problems, such as memory loss. Higher than normal blood glucose levels can damage nerve cells, supportive glial cells, and blood vessels in both peripheral nerves of the body and the brain.

Is memory loss from diabetes reversible?

The great news is that diabetes and prediabetes are preventable and even reversible in many cases and can help protect your memory.

Can diabetes affect your thinking?

High blood sugar can damage your blood vessels, resulting in poor blood circulation. And when there’s insufficient blood circulation in the brain, you might not think as clearly. Also, too much blood sugar can increase serotonin and neurotransmitters in the brain.

Can high sugar levels cause confusion?

Over time, high glucose levels can have serious repercussions, such as heart disease and stroke. But lower them too much and you could face immediate and severe side effects including confusion and cognitive impairment and, possibly, an increased risk of long-term cognitive decline [1][2].

Can high sugar make you confused?

Late symptoms of prolonged, elevated blood sugar levels are blurred vision and possibly numbness in your fingers and toes. Severely high levels of blood sugar may cause confusion or a coma.

Does sugar increase cognitive function?

Glucose and the mental performance

These may impair various cognitive functions such as attention, memory, and learning. Studies on glucose have demonstrated how administering this sugar can improve cognitive functioning in particular, short-term memory and attention.

Can prediabetes cause memory loss?

Diabetes and the Brain

Even mildly elevated blood sugar levels and prediabetes are significant problems and are associated with brain atrophy, memory problems, and dementia.

Can metformin lead to dementia?

Over the 6 years of evaluation, the incidence of dementia among people with diabetes treated with metformin was 6% (four patients) versus 14.5% (eight patients) in those not treated with metformin and 8.2% (73 patients) among those with no diabetes.

What kind of sugar does the brain need?

The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood.

Does the brain run better on ketones or glucose?

It turned out that Ketones are a much better energy source for the brain than Glucose because of their more efficient pathway. When Ketones are used to produce energy using Oxygen, more ATP is produced per molecule with Ketones than with Glucose.
