High level of sugar in the blood can lead to memory loss

Patients with high levels of sugar, with or without diabetes are at increased risk of developing some form of dementia

Individuals with high levels of sugar in the blood, even those with diabetes may have an increased risk to develop cognitive problems.

Previous research has shown that people with type 2 diabetes have a higher risk of developing some form of dementia.

Now, a new study conducted in Germany shows that even people who did not develop diabetes but have high levels of blood sugar can integrate this risk group.

The researchers looked at 143 people with an average age of 63 years. The members of the research did not have diabetes or pre-diabetes. Exclusion criteria were also people who were overweight who consumed more than 3.5 units of alcohol per day, and patients who have had a disability in memory.

Participants were tested for blood glucose testing memory. One of the tests to induce patients to recall a list of 15 words, 30 minutes after hearing them.

The researchers also performed brain scans of the participants in order to measure the size of the hippocampus (region linked to memory).

The results showed that the members of the study who had lower blood sugar had the highest scores on tests of memory, compared with those who had higher levels of blood sugar.

In tests of recall of words, the researchers found that patients recalled fewer words had higher levels of blood sugar.

The study results suggest that changes in lifestyle strategies in the pursuit of improving glucose levels in the long term may be an "out promising for preventing cognitive decline in aging."

"This quest for a healthier lifestyle includes, for example, avoid obesity (especially in middle age), consuming a diet rich in fiber, vegetables, protein and whole grain products, and perform regular physical activity," the study said.

Agnes Flöel, Charité University Medicine Berlin, who led the study, says that individuals at risk, such as obese and people over age 55, should conduct regular health checkups that include the monitoring of glucose levels HbA1c and fasting for early detection and treatment of elevated glucose levels.
