What Is Type 3 Diabetes? Insulin Resistance In The Brain That Could Trigger Alzheimer’s

Most people are aware of type 1 and type 2 diabetes, but did you know there is a type 3 diabetes as well! It is a more obscure term. Although it is not an accepted medical diagnosis, type 3 diabetes has been discussed in the literature as a possible relationship between insulin resistance in the brain and Alzheimer's disease. This link has been described to help explain how metabolic disorders impact brain health, causing cognitive decline and dementia.

What is Type 3 Diabetes?

Type 3 diabetes is more of a misnomer because it should not be confused with type 3c diabetes, which relates to pancreatic dysfunction. The term "type 3 diabetes," on the other hand, has been loosely used by some scientists to analogously propose that Alzheimer's disease is strongly implicated with insulin resistance in the brain.

This concept was conceptualized by Dr. Suzanne de la Monte and Dr. Jack Wands of Brown University in the year 2008. This hypothesis postulated that Alzheimer's disease may be called type 3 diabetes for it bears many similarities with glucose metabolism disorder type 2 diabetes. Their concept arises from the basic principle that insulin is fundamental to blood sugar regulation, but it is also the case with the brain. When brain cells become insulin-resistant, they lose access to glucose, impairing their function.

Research published in the Journal of Diabetes Science and Technology supports this hypothesis by indicating that insulin resistance can be a significant contributor to the occurrence of dementia, also referred to as Alzheimer's. The symptoms of memory loss and diminished reasoning are associated with impaired glucose metabolism in the body, especially in the cerebral tissue.

Symptoms of Type 3 Diabetes

Although type 3 diabetes is not a "medical term," its symptoms correlate well with Alzheimer's diseases that are known to reduce the ability to think in an efficient manner and bring down brain health. These signs are:

- Loss of memory, especially short-term.

- Poor judgment and judgment ability

- Failure in recognizing people or places familiar once.

- Failure in the process of reading, writing or processing numbers

- Anxiety, agitation, or mood changes.

- Disorganized thoughts or confusion

- Lack of impulse control

As the disease advances, patients may be afflicted with severe complications including an inability to swallow or control their bodily functions. In the final stages, most patients die from fatal complications such as aspiration pneumonia.

Causes of Type 3 Diabetes

This may not be well understood with regards to type 3 diabetes, or the exact link between insulin resistance and Alzheimer's disease. Some identified contributing factors include the following:

1. Insulin Resistance

Insulin acts as an important regulatory mechanism of brain functions such as memory and cognition. The reduction in insulin signaling may impair metabolism of brain cells, thus bringing about neurodegeneration.

2. Type 2 Diabetes

These diseases show a strong relationship and those individuals diagnosed with type 2 diabetes have double chances of getting Alzheimer's. In the two, the main causes can be chronic inflammation, oxidative stress, and a defect in glucose metabolism.

3. Environmental and Lifestyle Factors

Insulin resistance associated with obesity, stress, and an unhealthy diet is considered a cause that may increase the chances of Alzheimer's disease.

Researches in Frontiers in Neuroscience and The Lancet Neurology have also highlighted that drugs used for antidiabetic medication may be crucial for the prevention or at least slowing down the course of Alzheimer's.

Treatments for Type 3 Diabetes

In 2022, in a study in Pharmaceuticals, researchers studied biomarker uptake in brain regions implicated in the faulty uptake and metabolism of blood sugar in Alzheimer’s patients.

Emerging Therapies

Research into such treatments as intranasal insulin has also been promising. Intranasal delivery of insulin directly to the brain has been reported to enhance glucose uptake by brain cells, improve memory, and boost cognitive performance. While such clinical trials have been shown to be successful, additional research is needed for safety and efficacy.

Medications

For patients being aggressive or agitated, antipsychotic drugs may be prescribed; however, therapies such as cognitive rehabilitation as well as cognitive stimulation therapy serve to preserve memory and executive function.

Lifestyle Interventions

Diet, exercise, and stress management are critical in preventing and managing insulin resistance. A review in the Journal of Alzheimer's Disease also highlighted the benefits of Kirtan Kriya meditation, which can regulate genes involved in insulin and glucose metabolism, improve sleep, and reduce inflammation.

Can Type 3 Diabetes Be Prevented?

Although type 3 diabetes is not officially recognized, its connection to Alzheimer’s disease underscores the importance of proactive measures for brain health. Some prevention strategies include:

1. Healthy Diet

Consuming a balanced diet rich in antioxidants, whole grains, and healthy fats may support brain health.

2. Regular Exercise

Physical activity improves insulin sensitivity, reduces inflammation, and enhances overall metabolic health.

3. Stress Reduction

Mindfulness practices, including meditation, have been shown to lower stress levels, which can reduce the risk of cognitive decline.

The term type 3 diabetes brings out the complex relationship between metabolic disorders and brain health. Even though it is not a recognized medical condition, the concept emphasizes the crucial role of insulin in brain function and its possible contribution to Alzheimer's disease. Continued research will hopefully provide hope for therapies such as intranasal insulin and lifestyle modifications.

The World Health Organization (WHO)'s Montreal meeting focused on wearable technology like smartwatches and activity trackers as a reliable source of health tracking. The meeting discussed that wearables could in fact generate objective real-time data, which helps governments design targeted and evidence-based health interventions.

Physicians in the Montreal meetings discussed that wrist-worn devices are more reliable than traditional self-reported surveys. This is because the self-reported surveys could underestimate the levels of physical inactivity.

“Metrics such as step count, moderate-to-vigorous physical activity and sedentary time directly correlate with cardiovascular disease, diabetes and mental health outcomes. Having population-level data allows for early and preventive strategies,” said Dr Venkat Nani Kumar, consultant in internal medicine.

WHO Montreal Meeting: How Have Doctors Reacted The Shift To Wearables?

Doctors in India have welcomed this shift to wearable devices as a better way to generate data and make policies. Dr Kiran Madhala, professor at Gandhi Medical College, Secunderabad, said WHO’s shift reflects rapid advances in artificial intelligence and digital health tools, calling it a progressive step towards improved monitoring of physical activity worldwide.

City-based doctors also underlined the need for inclusive validation of devices. “Wearables must recognise varied movement patterns and step equivalents, especially in ageing populations,” a physician said, while stressing the importance of data privacy and ethical use of health information.

WHO Montreal Meeting: What Are Wearable Health Devices?

As per a 2022 study published in JMIR MHealth and UHealth, wearables refer to devices that are worn by individuals. In health care field, they assist with individual monitoring and diagnosis. Wearables are “seamlessly embedded portable computers...worn on the body," notes another 2018 study published in Telematics Informatics.

A 2018 study published in the journal Sensors noted that wearable health devices are increasingly helping people to better monitor their health status both at an activity/fitness level for self health tracking and at a medical level providing more data to clinicians with a potential for earlier diagnostic and guidance of treatment.

WHO Montreal Meeting: What Are Some Examples Of Wearables?

Blood Pressure Monitor

This is a blood pressure monitor that consists of a cuff that is placed in upper arm with a digital display that provides real time reading of systolic and diastolic blood pressure.

Glucose Monitoring Device

This device estimates your glucose levels in every few minutes. It can be worn in upper arm, with a phone sensor connected to measure readings. It also includes real time glucose alarms to make informed decisions.

Wearable ECG Monitor

ECG patches are interconnected with smartphones, where one can see their readings. They not only measure electrocardiograms, but also detect any abnormalities.

Fitness Tracker

Smartwatches or fitbits that could be worn on your wrist. They help track real time data of your health, steps, heart rate, calorie consumptions, and even sleep patterns. It can also help keep track of oxygen levels.

Integrated Activewear

These activewears come with microscopic sensors to safeguard wearer's body or assist them in reaching their fitness objective.

Fact Check: Doctors Bust Common Myths Around Epilepsy and Explain Why Early Treatment Matters

Updated Feb 10, 2026 | 02:00 AM IST

SummaryDoctors say epilepsy is a common, treatable brain disorder often surrounded by myths in India. Early diagnosis, regular medication and advanced treatments can control seizures in most patients, while awareness is key to reducing stigma and improving quality of life.

Epilepsy affects more than 15 million people in India, yet it remains one of the most misunderstood neurological conditions. Despite being a treatable brain disorder, fear, stigma and long-standing myths continue to delay diagnosis and care, especially in smaller towns and rural areas. Doctors say this lack of awareness often causes more harm than the condition itself.

According to the World Health Organization (WHO), nearly 50 million people worldwide live with epilepsy, making it one of the most common neurological disorders. The WHO also estimates that up to 70 per cent of people with epilepsy can live seizure-free if properly diagnosed and treated. Yet, in low- and middle-income countries, almost three-fourths of patients do not receive the treatment they need.

What Really Happens During a Seizure

Dr Madhukar Bhardwaj, Director and Head of Neurology at Aakash Healthcare, explains that epilepsy occurs due to a sudden disturbance in the brain’s electrical activity. “A seizure happens when the brain’s electrical signals stop working normally for a short time,” he says.

This can cause a wide range of symptoms, from jerking movements and falling unconscious to staring spells or brief confusion. “Some seizures last just a few seconds and may go unnoticed, while others can be severe,” Dr Bhardwaj adds.

Breaking Dangerous and Persistent Myths

Despite medical clarity, myths around epilepsy remain deeply rooted. Dr Bhardwaj points out that many people still believe epilepsy is caused by ghosts, black magic, or divine punishment. “Others think it spreads by touch or that people with epilepsy cannot study, work or get married,” he says.

One of the most dangerous misconceptions is putting an object into a person’s mouth during a seizure. “This is completely false and can seriously injure the patient,” Dr Bhardwaj warns. Doctors stress that epilepsy should be treated like any other chronic condition, such as diabetes or high blood pressure, not as a social taboo.

Understanding the Real Causes of Epilepsy

Dr Neha Kapoor, Associate Director and Head of Neurology at Asian Hospital, says epilepsy does not have one single cause. “In many cases, we are unable to find an exact reason,” she explains. However, known causes include genetic factors, head injuries from accidents, brain infections like meningitis, strokes, and other forms of brain damage.

In children, epilepsy may result from lack of oxygen at birth or abnormal brain development before birth. Dr Kapoor also clarifies a common misunderstanding: “Stress, lack of sleep, and alcohol can trigger seizures, but they are not the root cause of epilepsy.”

Why Epilepsy Often Goes Undiagnosed

Not all seizures look dramatic, which leads to frequent delays in diagnosis. “Not all seizures involve shaking,” says Dr Praveen Gupta, Chairman at Marengo Asia International Institute of Neuro and Spine (MAIINS). “Some look like daydreaming or sudden confusion, which is why epilepsy is often missed.”

Dr Gupta notes that many patients reach specialists very late due to fear and misinformation. “With timely treatment, most people with epilepsy can live completely normal lives,” he says.

Advanced Treatment and Surgical Options

Nearly 70 per cent of epilepsy patients can control seizures with regular medication, according to doctors. For those who do not respond to medicines, known as drug-resistant epilepsy, advanced treatment options are now available in India.

“Epilepsy surgery is being used successfully,” Dr Gupta explains. “We carefully identify the part of the brain causing seizures and treat it safely. This can greatly reduce or even stop seizures.” He adds that modern surgical and neuro-robotic techniques are changing outcomes and offering renewed hope.

Addressing Sexual Health and Quality of Life

Epilepsy can also affect aspects of life that are rarely discussed, including sexual health. Dr Vineet Malhotra, Principal Consultant at SCM Healthcare, says seizures, stress and some anti-seizure medications may impact energy levels, hormones and sexual desire in men.

“However, these issues are manageable,” Dr Malhotra says. “With counselling, lifestyle changes and medication adjustments, patients can lead healthy, active and fulfilling lives.”

Doctors agree that awareness, early diagnosis and breaking myths are key to ensuring epilepsy is treated as what it truly is, a manageable medical condition, not a social label.

Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also called an arrhythmia and can create blood clots in the heart, which can increase your risk of having a stroke by five times.

When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular and blood doesn't flow as well as it should from the atria to the lower chambers of the heart (the two ventricles).

In this case, the risk of developing blood clots in your heart increases, which can not only cause a heart attack but also damage vital organs such as your brain. An AFib may happen in brief episodes, or it may be a permanent condition.

Common symptoms include palpitations (the feeling that your heart is racing, pounding, fluttering or like you have missed heartbeats), chest pain, finding it harder to exercise, tiredness, shortness of breath, dizziness or feeling faint.

The death rate from AFib as the primary or a contributing cause of death has been rising for more than two decades.

Over 454,000 people with AFib are hospitalized in the US each year, out of which 158,000 die of the cause. It is estimated that 12.1 million people in the US will have AFib in the US will have AFib by 2050.

Who Is At Risk Of Having AFib?

Risk factors for AFib include:

  • Advancing age.
  • High blood pressure.
  • Obesity.
  • European ancestry.
  • Diabetes.
  • Heart failure.
  • Ischemic heart disease.
  • Hyperthyroidism.
  • Chronic kidney disease.
  • Moderate to heavy alcohol use.
  • Smoking.
  • Enlargement of the chambers on the left side of the heart.
In certain cases, AFib can be triggered by other things, such as alcohol, caffeine, smoking, recreational drugs, emotional stress and spicy food.

Treatment for AFib includes medications to control the heart's rhythm and rate, therapy to shock the heart back to a regular rhythm and procedures to block faulty heart signals.

A person with atrial fibrillation also may have a related heart rhythm disorder called atrial flutter. The treatments for AFib and atrial flutter are similar.

How To Improve Your Heart Health

Experts recommend following the below to reduce yor risk of stroke or developing AFib and maintaining heart health:

  • Don't smoke or use tobacco.
  • Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity (or an equal combination of both) each week. Eat a heart-healthy diet.
  • Stay at a healthy weight.
  • Get quality sleep.
  • Manage stress levels
  • Get regular health screening tests.
  • Eat a fiber, nuts and fish-rich diet
  • Limit salt intake
  • Reduce saturated fat intake
