Can Diabetes Cause Memory Loss?

Memory loss is the main symptom of Alzheimer’s disease. But does your body’s inability to process insulin cause memory loss? Diabetes is a condition which can lead to various complications in the body. There speculations pointing to it being one of the main causes behind memory loss.


The Link Between Diabetes and Memory Loss

Diabetes happens because of the body’s inability to produce insulin, a hormone that converts the sugar into energy. According to medical experts, the metabolic disease can lead to memory loss because of its ability to affect the brain’s blood vessels. The various side effects can also affect one’s reasoning and learning abilities, if it’s not controlled in time.

According to studies, people who are in the pre-diabetic stage or cannot process blood sugar in the normal way are at high risk of suffering from poor memory or memory loss. Research has further shown that people suffering from diabetes could be at high risk to developing Alzheimer’s disease, as compared to those who are not suffering from the chronic metabolic disease.

New research has shown however that people who are suffering from both diabetes and Alzheimer’s will have memory loss at a much slower rate than those people who are only suffering from Alzheimer’s alone. Another study showed similar findings. In another study, experts observed almost 608 people who suffered from mild to moderate Alzheimer’s disease for more than four years. These people’s thinking and reasoning abilities have also been tested and 63 of them have been diagnosed with diabetes.


Before the study was conducted, those with and without diabetes have secured the same scores in several cognition tests. In more than a period of six months, researchers observed that the rate of the cell damage in those with diabetes and Alzheimer’s was less than those who only suffer from Alzheimer’s, yet the reason for this remains unclear.

Diabetes and Memory Loss Among Elderlies

Diabetes may be one of the potential causes behind memory loss among elderlies. A group of medical experts conducted a 5 year research and found that diabetes is indeed the prime cause behind the chronic inflammation of the brain among elderlies. Such inflammation could affect the blood vessels and weakens the major brain tissues gradually.

This starts by affecting the gray matter that affects a person’s reasoning and decision-making abilities. It also makes the individual less able to perform even the simplest of all tasks.

Many medical experts would agree that from the age of 65, the brain of an average person starts shrinking. Our brains shrink around one percent each year, although for a diabetic patient, this could be as high as 12%.
