Some people use the term “type 3 diabetes” to describe Alzheimer’s disease. However, official health organizations do not accept this term, and most doctors do not use it for diagnostic purposes. Some scientists believe insulin resistance causes amyloid plaques, inflammation, and oxidative stress in the brain.
However, type 3 diabetes involves the brain and leads to Alzheimer’s disease.
This article explains what type 3 diabetes is and how it links to Alzheimer’s disease. It discusses the possible causes and risk factors, along with treatment and prevention strategies.
“Type 3 diabetes” is a term some people use to describe Alzheimer’s disease. Some scientists proposed the term because they believe insulin dysregulation in the brain causes dementia.
However, type 3 diabetes is not an officially recognized health condition. The American Diabetes Association, as well as other major health organizations, does not list Alzheimer’s disease as a type of diabetes within their classification.
Other types of diabetes include type 1, type 2, and gestational diabetes. In addition, some research uses the term “type 3c” to classify pancreatogenic diabetes that may result from pancreatitis. This type is different from Alzheimer’s disease.
Doctors do not use “type 3 diabetes” as a diagnostic term, because it is not an official classification. They can, however, diagnose Alzheimer’s disease using physical and mental tests, neurological exams, and brain imaging.
According to the Alzheimer’s Association, the early signs and symptoms of Alzheimer’s disease include:
- memory loss that negatively impacts daily life
- trouble resolving problems or making plans
- difficulty carrying out familiar tasks
- confusion about location or time
- difficulty using and understanding written and spoken language
- mislaying things
- decreased judgment
- withdrawal from social activities or work
- mood and personality changes
It is important to note that some changes in memory and habits can be part of aging. However, if a person is concerned about any changes they are experiencing, they should seek guidance from a doctor.
Authors of a
They describe Alzheimer’s disease as a neuroendocrine disease involving impaired insulin and insulin-like growth factor (IGF) signaling. The condition can also involve inflammation and oxidative stress.
The authors note that while obesity and type 2 diabetes might contribute to the development of Alzheimer’s disease, they are not sufficient causes by themselves.
- a diet high in calories, sugar, and fat and low in fiber
- low socioeconomic status
- exposure to stress
- race and ethnicity
- lack of physical activity
- family history
- birth weight
The same study indicates that high blood pressure and impaired lipid, or fat, transportation play a role in the development of Alzheimer’s disease.

There is no cure for type 3 diabetes (Alzheimer’s disease), but doctors may prescribe drugs to slow the progression of the condition or treat its symptoms.
Changing disease progression
Aducanumab is an anti-myloid antibody drug that may help reduce cognitive and functional decline in people in the early stages of Alzheimer’s disease.
Medications that can lessen memory loss and thinking issues in Alzheimer’s disease include donepezil and galantamine.
Drugs that may improve behavioral and psychological symptoms include suvorexant, which may help prevent insomnia.
Additionally, some people use alternative and natural treatments. However, the Alzheimer’s Association notes that these may not be effective or safe.
According to the
There is also no definite evidence concerning dietary therapies for Alzheimer’s disease prevention.
Although scientists have not proven the effectiveness of any strategies for avoiding Alzheimer’s disease, managing blood glucose may be a sensible approach.
A doctor may also prescribe metformin to delay the onset of or treat diabetes.
There are fundamental differences between type 3 diabetes (Alzheimer’s disease) and type 1 and type 2 diabetes. Alzheimer’s disease is an entirely separate condition.
In the following table, we compare diabetes types 1, 2, and 3.
|Type 1 diabetes||Type 2 diabetes||Type 3 diabetes (Alzheimer’s disease)|
|What is happening?||The body attacks the cells in the pancreas, which causes them to lose the ability to make insulin.||The body does not use insulin well or cannot make enough to keep up with the demand.||The body experiences impaired insulin and IGF signaling, oxidative stress, and inflammation.|
|Risk factors and causes||Scientists currently do not know the exact cause of type 1 diabetes, but genes or viruses may trigger it.||Overweight, obesity, and physical inactivity may lead to type 2 diabetes.||Possible risk factors are poor diet, obesity, type 2 diabetes, inactivity, genes, ethnicity, and high blood pressure.|
|Management||Management involves insulin medications, such as metformin.||Medication, diet, and exercise may help people with type 2 diabetes.||Management of Alzheimer’s disease involves medications and support. People can manage blood sugar through diet and lifestyle.|
|Treatment and prevention||There is no cure, but medication can help manage the condition. Studies on prevention are ongoing.||Lifestyle and dietary changes can help treat and prevent type 2 diabetes.||Treatment of Alzheimer’s disease involves medication, although there is no cure. Physical activity, a healthy diet, and a moderate body weight can help prevent insulin resistance.|
There is no cure for type 3 diabetes (Alzheimer’s disease). However, there are many treatment options available that may lessen the severity of symptoms and prolong a person’s life.
Some people with Alzheimer’s disease will not develop symptoms for years, although this can vary from person to person.
Most people with Alzheimer’s disease will die from another cause. However, since Alzheimer’s disease causes neurological problems, it could lead to:
- a person inhaling food into their lungs, possibly causing a chest infection
- difficulty eating
- reduced appetite
People with Alzheimer’s disease may require palliative care to improve their quality of life in the final stages of the condition.
“Type 3 diabetes” is a term some people use to describe Alzheimer’s disease, but major health organizations do not recognize it as a type of diabetes in their classifications.
Scientists believe that insulin resistance in the brain can lead to the characteristic symptoms of Alzheimer’s disease, such as amyloid plaques, oxidative stress, and inflammation.
While researchers have called for more studies, they acknowledge that some factors seem to increase the risk of developing Alzheimer’s disease. These include overweight, little physical activity, and high blood pressure.
People can use diet and lifestyle changes to manage their weight and blood sugar, which may play a role in preventing cognitive decline.
