Type 3 diabetes is a term some researchers use for Alzheimer’s disease linked to insulin resistance in the brain. It is not an official medical diagnosis. Memory loss and trouble thinking are the main symptoms. Managing blood sugar, eating well and staying active may lower the risk.
Type 3 diabetes: quick answers
What is type 3 diabetes? It is a proposed name for Alzheimer’s disease caused by insulin resistance in the brain.
Is type 3 diabetes the same as type 3c? No. Type 3c diabetes comes from diseases of the pancreas, such as chronic pancreatitis.
Can type 3 diabetes be prevented? Controlling type 2 diabetes, exercising and keeping a healthy weight may help protect the brain.
Type 3 diabetes is a complex and often misunderstood condition. It is not as commonly discussed as type 1 or type 2 diabetes. It still has significant implications for those it affects. This blog gives an overview of type 3 diabetes, including its symptoms, causes and diet plans. These can help you manage the condition.
Type 2 diabetes mellitus (DM) and dementia are two diseases that are quite common nowadays and are likely linked. As a result, the name type 3 diabetes was coined. It tries to bring together the possible disease processes shared by diabetes mellitus (DM) and Alzheimer’s disease (AD). In the last decade, substantial epidemiological evidence linking diabetes and dementia has emerged.
Diabetes is linked to a higher risk of dementia in tnd when diabetes is detected early on in life.
Although the impact is less in older groups, diabetes remains a risk factor even in those over 85.
Hyperinsulinemia and insulin resistance are considered health risks for Alzheimer’s disease because they can cause neuron death and enhance the production of extracellular -amyloid deposits.
1-3 Excess-Amyloid can eliminate amyloid in normal circumstances by the lipoprotein receptor-related protein 1 (which lowers if insulin resistance is present) or by a breakdown process involving the insulin-degrading enzyme (IDE).
Insulin will reduce insulin transfer through the blood-brain barrier if persistent peripheral hyperinsulinemia persists.
Diabetes mellitus (commonly known as DM or diabetes) is a disorder in which your body has trouble transforming sugar into energy.
Classification of Diabetes Mellitus
Diabetes mellitus is classified into several types, each with its unique characteristics and causes.
Type 1 and Type 2 Diabetes
Type- 1 diabetes is an autoimmune condition where the body attacks insulin-producing cells.
Type -2 diabetes is more common and often related to lifestyle factors such as diet and exercise.
Type 3 and Type 3c Diabetes
Type 3 diabetes is associated with Alzheimer’s disease, while Type 3c diabetes relates to pancreatic diseases that impair insulin production.
There are three types of diabetes that most people are familiar with
Type 1 diabetes (T1DM) is a long-term health issue. This is your pancreas’ endocrine system fails to produce sufficient insulin, causing your blood glucose levels to rise excessively.
Type 2 diabetes (T2DM) is a long-term disorder. Your body accumulates insulin resistance, and your blood sugar levels rise too high.
Gestational diabetes (GDM) develops during pregnancy when blood sugar levels are abnormally high.
According to several studies, Alzheimer’s disease categorizes as a form of diabetes known as type 3 diabetes.
The phrase “type 3 diabetes” reflects a theory that Alzheimer’s disease, a leading cause of dementia, is driven by insulin resistance. The theory also points to a malfunction of insulin-like growth factor that happens only in the brain.
Some people use this term for people who have type 2 diabetes and also have Alzheimer’s disease dementia.
The diagnosis of type 3 diabetes is contentious. It is not universally acknowledged as a clinical diagnosis by the medical profession.
The health condition referred to above as “type 3 diabetes” don’t mistake it with type 3c diabetes mellitus.
The pancreas contains both endocrine and exocrine glands, each with its function.
Insulin is a hormone produced and secreted by beta-islet cells in the endocrine pancreas tissue known as the Islets of Langerhans.
T3cDM occurs when the exocrine pancreas gets sick and subsequently produces secondary damage to the endocrine pancreas, resulting in DM. Pathologies of the exocrine pancreas that can lead to T3cDM include:
- Exocrine pancreatic malignancy
- Chronic pancreatitis
- Cystic fibrosis
The Link Between Diabetes and Alzheimer’s disease
According to the Mayo Clinic, Alzheimer’s disease and type 2 diabetes have already been connected.
The progression of Alzheimer’s disease has been associated with insulin resistance inside the brain. Alzheimer’s disease is also known as “brain diabetes.” This claim is supported by science, although it is oversimplified..
Diabetes, if remains unaddressed, can lead to severe complications, including those in your brain, over time.
Many patients with type 2 diabetes are unaware that they have the disease, which can cause delays in assessment and treatment.
As a result, people with type 2 diabetes, particularly undiagnosed diabetes, are more likely to suffer from this type of damage.
Diabetes can lead to chemical imbalances in the brain, which can lead to Alzheimer’s disease. High blood glucose levels can also cause inflammation, which can harm brain cells.
Diabetes is recognized as a risk factor for vascular dementia because of these factors.
Vascular dementia can be a separate diagnosis with its own symptoms. It can also be a precursor to Alzheimer’s disease.
This process’ science is debatable. For now, some cases of Alzheimer’s disease and other forms of dementia appear not to be linked to insulin resistance.
Causes and risk factors of type 3 diabetes
A 2016 study found that people with type 2 diabetes are up to 60% more likely to develop dementia. This includes Alzheimer’s disease and vascular dementia.
More than 100,000 adults with dementia took part in this study. Women with type 2 diabetes had a higher risk of acquiring vascular dementia than males, according to the study.
The following are some of the risk factors for type 2 diabetes:
- A history of diabetes in the family
- Hypertension (high blood pressure)
- Being obese or overweight
- Anxiety and polycystic ovary syndrome, among other chronic health issues (PCOS)
Symptoms of type 3 Diabetes
Early Warning Signs
Identifying early symptoms of Type 3 diabetes can be challenging but crucial for timely intervention.
Cognitive Decline
Early symptoms often include mild cognitive decline, such as difficulty remembering recent events or conversations.
Memory Loss
Progressive memory loss is a significant symptom, indicating the deteriorating effect of diabetes on brain function.
Advanced Symptoms
As Type 3 diabetes progresses, symptoms become more pronounced and severe.
Dementia Type 3 Diabetes
The condition can lead to dementia, characterized by severe cognitive impairment and the inability to perform daily activities.
Diagnosis of type 3 diabetes
Type 3 diabetes does not have a specific test. Alzheimer’s disease is diagnosed using the following criteria:
- a neurological evaluation
- a medical history
- neurophysiological screening
Several inquiries about your family history and symptoms will be asked by your healthcare practitioner.
Imaging tests of the head, such as MRI and CT scans, can show your doctor how your brain is performing.
Cerebrospinal fluid tests can also be used to look for signs of Alzheimer’s disease.
You may have symptoms of type 2 diabetes and Alzheimer’s without a confirmed diagnosis of either. In that case, your healthcare provider may order a fasting blood glucose test and a glycated hemoglobin test.
If you have type 2 diabetes, it’s critical that you start treatment right away.
Type 2 diabetes treatment may reduce damage to your body, including your brain, and may decrease the progression of Alzheimer’s disease.
Medical Tests
Diagnosis typically involves a combination of tests to assess both diabetes and cognitive function.
Blood Glucose Levels
Regular monitoring of blood glucose levels is essential for managing diabetes.
Cognitive Assessments
Cognitive tests help evaluate the extent of memory loss and other cognitive impairments.
Clinical Criteria
A formal diagnosis requires meeting specific clinical criteria, including symptoms and test results.
Treatment for Type 3 Diabetes
People with the following conditions have different treatment options:
Alzheimer’s
Lifestyle changes can be an important part of your treatment. Examples include changing your food and adding exercise to your daily routine.
Here are some more therapy suggestions:
As per Mayo Clinic, if you’re obese, you should strive to shed 5 to 7% of your body mass. This may help prevent the development of pre-DM2 to DM2 by preventing organ damage caused by high blood sugar levels.
- A low-fat, high-fiber diet rich in fruits and veggies can help alleviate problems.
- Quitting smoking is advised if you smoke since it can help you to manage your health.
- If you have type 2 diabetes with Alzheimer’s disease, controlling your blood sugar is essential for slowing dementia development.
- Anti-diabetes medications metformin and insulin, according to a 2014 study, may reduce the risk of diabetes-related brain damage.
- Prescription medications are available for the treatment of Alzheimer’s dementia cognitive symptoms, but it’s uncertain if they have a major impact on the disease’s symptoms.
- Acetylcholinesterase inhibitors like donepezil, galantamine, and rivastigmine can improve the way your body’s cells communicate.
Memantine (Namenda), an NMDA-receptor antagonist, may also help to reduce symptoms and postpone the onset of Alzheimer’s disease.
Mood changes and sorrow are two signs of Alzheimer’s disease and other dementia types that may be treated with psychotropic medications. \
Antidepressants and anti-anxiety medications may be prescribed in some cases.
Some people may require a low-dose antipsychotic medication later on in the dementia progression.
The future of type 3 diabetes
When Alzheimer’s disease is accompanied by insulin resistance in the brain, it is known as type 3 diabetes.
As a result, your prognosis varies. It depends on factors such as your diabetes medication and the severity of your dementia.
Researchers who support a type 3 diabetes diagnosis argue that good control of diabetes may delay Alzheimer’s. This means managing it with food, exercise and medication. The evidence is mixed.
Your prognosis will also determined by how promptly you discovered and how your doctor views your specific scenario.
The sooner you begin therapy, the more likely you are to have a great outcome.
Once Alzheimer’s disease is found in a patient, life expectancy is generally believed to be 3 to 11 years.
After being diagnosed with Alzheimer’s disease person might live for up to 20 years.
How to prevent Type 3 diabetes
If you already have type 2 diabetes, there are ways to treat it better. They can also reduce your chance of developing type 3 diabetes.
Here are a few tried-and-true strategies for treating type 2 diabetes and preventing organ damage:
- Try exercising for 30 minutes four times a week and eat healthy meals that are low in saturated fat, high in protein, and high in fiber.
- Check your blood sugar levels as directed by your healthcare provider.
- Take prescription drugs on time and as directed.
- Maintain your cholesterol levels.
- Keep healthy body weight.
Type 3 diabetes (Alzheimer’s disease) has no known cure.
There are, however, a variety of therapies. They can help reduce the intensity of symptoms and extend a person’s life.
Even though this varies from person to person, some persons with Alzheimer’s disease do not display symptoms for years.
The majority of Alzheimer’s patients eventually die from a cause other than the illness. Alzheimer’s disease, on the other hand, can create neurological difficulties, which can lead to:
a person breathing food into their lungs, possibly resulting in chest infection, trouble eating, and/or a loss of appetite.
In the last stages of Alzheimer’s disease, individuals may require palliative care to enhance their quality of life.
Scientists say insulin resistance in the brain can cause amyloid plaques, oxidative stress and inflammation. All of these are hallmarks of Alzheimer’s disease.
While further research is needed, investigations indicate that certain factors appear to raise the risk of Alzheimer’s disease. Obesity, a lack of physical activity, and high blood pressure are all examples.
Diet and lifestyle adjustments can help people manage their weight and blood glucose, which may help them avoid cognitive deterioration.

Answers to Frequently Asked Question on Type 3 Diabetes
What is type of 3 diabetes?
Type 3 diabetes is a term used to describe the correlation between diabetes and Alzheimer’s disease. It represents a form of diabetes that exhibits characteristics of both types but primarily affects cognitive function.
Can Type 3 diabetes be cured?
Alzheimer’s disease, or type 3 diabetes, has no known treatment. However, a person’s life may be prolonged and the intensity of their symptoms may be lessened by several treatments.
How is type 3 diabetes diagnosed?
There is no specific test for type 3 diabetes. Alzheimer’s disease is diagnosed based on: a neurological examination, medical history, and neurophysiological testing. Your primary care provider will ask several questions about your family history and your symptoms.
How do you control type 3 diabetes?
People with the condition typically take an oral diabetes medication (such as metformin) and/or take synthetic insulin (with injections or an insulin pump). Your treatment needs may change over time if your pancreas becomes more damaged. For example, an oral medication may work well to manage your blood sugar at first.
Why is Alzheimer’s called type 3 diabetes?
Recently researchers proposed the term ‘Type-3-Diabetes’ for Alzheimer’s disease (AD) because of the shared molecular and cellular features among Type-1-Diabetes, Type-2-Diabetes and insulin resistance associated with memory deficits and cognitive decline in elderly individuals.
Conclusion
In conclusion, Type 3 diabetes, also known as Alzheimer’s disease, presents a complex interplay between insulin resistance, brain function, and neurodegeneration. The exact causes remain unclear. Emerging research suggests that metabolic dysregulation, genetic predisposition and lifestyle factors contribute significantly. Recognizing the symptoms early, such as cognitive decline and memory impairment, is crucial for timely intervention. Current treatment approaches focus on managing blood sugar levels, promoting neuroprotective strategies, and adopting a healthy lifestyle. However, more research is needed to understand how type 3 diabetes develops. It is also needed to develop more effective prevention and treatments.

Type 3 diabetes: frequently asked questions
Is type 3 diabetes real?
Type 3 diabetes is not an official diagnosis. Researchers use the term for evidence that poor insulin signalling in the brain may contribute to Alzheimer’s disease. Type 3c diabetes, which follows damage to the pancreas, is a recognised type.
What is type 3 diabetes called?
You may see it called “diabetes of the brain” or “Alzheimer’s-related insulin resistance”. Doctors use “type 3c” or “pancreatogenic” diabetes for diabetes that comes from pancreas disease.
What are the symptoms of type 3 diabetes?
For the Alzheimer’s link, symptoms are memory loss, confusion and difficulty with familiar tasks. For type 3c diabetes, they are thirst, frequent urination, unplanned weight loss and fatty stools. Only a doctor can tell these apart.
Does type 2 diabetes raise the risk of dementia?
Studies show people with type 2 diabetes have a higher risk of dementia. Keeping blood sugar, blood pressure and cholesterol in range supports brain health. So does staying active. Nothing is proven to prevent Alzheimer’s disease, though.
When should I see a doctor?
See a doctor if you or a family member has new memory problems. Also see one if you have diabetes symptoms along with long-term stomach pain, pancreatitis or pancreatic surgery.
