Will I get Alzheimer’s Disease if I have Type 2 diabetes?


I’ve heard that my risk for Alzheimer’s disease goes up if I have Type 2 Diabetes?

Is Alzheimer’s disease Type 3 diabetes? The research on Alzheimer’s disease (AD) being a type of diabetes for the brain is relatively new. This disease is caused, in part, by insulin resistance in the brain. When brain cells don’t get enough glucose they malfunction. This can lead to cognitive decline and even brain cell death.

Alzheimer’s Disease is debilitating. Memory loss, confusion, and inability to learn new things are all symptoms. People with Alzheimer’s Disease have trouble coping with new situations. They can’t organize or communicate their thoughts clearly. The first sign is an inability to hold onto newly learned information.


Are you, or someone you love,  experiencing any of these symptoms?

  • Difficulty in solving problems
  • Inability to complete familiar tasks
  • Memory loss
  • Confusion about dates and times
  • Difficulty with visual images
  • Challenges coming up with the right word
  • Inability to write as well as you used to

If any of these issues are affecting the daily life of yourself or someone you love, it’s time to talk to your doctor. Early intervention is key. Read this article to find out more about what happens if you don’t do anything about your Type 2 Diabetes. 

Risk for Type 2 diabetes patients

A few studies on large groups of people with Type 2 diabetes were done. These studies suggest that people with Type 2 diabetes are at a greater risk for Alzheimer’s Disease. High blood sugar causes damage to internal organs. The brain is one such organ. High blood sugar also causes inflammation. Inflammation damages the brain.

People with high blood sugars have more beta-amyloid protein1 This protein is one of the signs of Alzheimer’s Disease. People who are in the early stages of Type 2 already show signs of brain dysfunction.

We know that insulin resistance in the body leads to Type 2 diabetes. Insulin resistance in the brain leads to the formation of plaques2. These plaques cause Alzheimer’s Disease.

It’s important to start making changes now to protect your brain. One of the horrible things about Alzheimer’s Disease is the loss of cognitive function. You can’t learn new habits. Healthy habits are going to save your body and brain. Waiting until the brain malfunctions to start these healthy habits will be almost impossible. 

You need your brain to help you make healthy changes. If you make it a rule to avoid sugar and carbs now, it will help you later. 

Start now. Get your blood sugar under control. Talk to your doctor about making a plan to lower your risk of Alzheimer’s Disease.
