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.

I'm Not Afraid Of Germs, I Snorted Cocaine Off Toilet Seats, Says US Secretary of Health, RFK Jr

Updated Feb 15, 2026 | 02:16 AM IST

SummaryUS Health Secretary Robert F. Kennedy Jr. said he once snorted cocaine off toilet seats and was unafraid of germs, drawing criticism. Experts note bacterial exposure does not confer viral immunity, amid his longstanding controversial vaccine views.
I'm Not Afraid Of Germs, I Snorted Cocaine Off Toilet Seats, Says US Secretary of Health, RFK Jr

"I'm not scared of a germ, I used to snort cocaine off of toilet seats," said the US Secretary of Health and Human Services Robert F Kennedy Jr. Now 72, he said during a Theo Von podcast that he continued with in-person rehab meeting during pandemic due to his addiction because of his robust approach to infection.

In a statement, he said, "I said, ‘I don’t care what happens, I’m going to a meeting every day’,” he told Von. “I said, ‘I’m not scared of a germ — I used to snort cocaine off of toilet seats — and I know this disease [addiction] will kill me if I don’t treat it, which means, for me, going to meetings every day … for me, it was survival.”

What Is Wrong With RFK Jr's Statement?

While toilet seat may not be the dirtiest item in an average household, as scientists, including professor of microbiology at the University of Arizona, Dr Chuck Gerba told BBC that there are other dirtier items too. The statement to snort off a toilet seat could have a wrong tone.

While there exist other items with more bacteria than toilet, it is no safe to snort things off toilet seat and absolutely not to do drugs and to brag about it. This feels especially off when it comes from a Health Secretary.

On an average, a toilet seat typically has around 50 to 3,000 bacteria per square inch. A toilet seat could have many bacteria, including E. coli, Salmonella, norovirus and Shigella. They can cause gastrointestinal distress.

What is wrong with RFK Jr.'s statement is that having frequent encounters with fecal bacteria will not scientifically make him immune against the respiratory viruses which were common during the COVID-19 pandemic.

This is because bacteria are single-celled, living organisms that can live independently, while viruses are much smaller, non-living agents and require a host cell to reproduce. The basic difference in its composition and how they function after entering the body is the reason why exposure to bacteria does not necessarily means one is protected or has immunity against a virus.

RFK Jr And His Anti-Vaxxer Stance

He is the nephew of former US President John F Kennedy popularly known as JFK, who was a democratic candidate. However, RFK Jr., who earlier filed candidature as a Democrat, then switched to an independent candidate and endorsed Trump heavily.

RFK Jr. works closely with many anti-vaccine activists who work for his nonprofit group Children's Health Defense. While in his recent speech, he said that he has "never been anti-vax and have never told the public to avoid vaccination", his track record shows otherwise.

In a podcast interview, he said, "There is no vaccine that is safe and effective" and told FOX News that he still believes in the now long-debunked idea that vaccines can cause autism. In another 2021 podcast, he urged people to "resist" CDC guidelines on getting their kids vaccinated. "I see somebody on a hiking trail carrying a little baby and I say to him, better not get them vaccinated," he said.

His non-profit also led an anti-vax campaign sticker and he appeared next on the screen to a sticker that read: "If you are not an anti-vaxxer you are not paying attention," reports AP.

Five weeks after the launch of Novo Nordisk's weight loss pill, Wegovy, 38,220 US prescriptions have been reported by IQVIA for the same. The company shares too climbed up by 4% on Friday, and touched the levels last seen in October.

The oral version of the Wegovy pill became available to US patients earlier this month after the US Food and Drug Administration (FDA) approved it in December.

How Effective Is The Wegovy Pill?

After injection by Novo Nordisk, of the same name, Wegovy, which has been on the market since 2021, its popularity grew so much that it was in short supply until February 2025. The pill version has now come out, which many experts believe will expand its accessibility. As the monthly supply of pill is expected to be cheaper than the monthly supply of the weight loss injection.

A study published in the New England Journal of Medicine show that a 25 milligram Wegovy pill led to 13.6% reduction in weight on average over 64 weeks. When compared to placebo, the result was only 2.2% of weight loss. Novo Nordisk says that those who stayed on the treatment and reduced their calorie intake, it would lead to a loss of 16.6% of their weight.

How To Use The Weight Loss Pill?

The first step lies in buying the correct and safe weight loss pill. Make sure the weight loss pills are clinically proven option for people to use to reduce their weight.

Take the pill with a glass of water. Make sure to always have the pill prescribed and follow the instructions that you GP has told. Store the pill in a cold place, however avoid freezing the medicine. Keep the medicine out of a child's reach. In some weight loss pills, if you miss your dosage, you can take it within 1 hour, however, clarify these doubts from your GP. A pill can usually be consumed within an hour of a fat-containing meal up to three times a day., however, the Wegovy pill must be taken on an empty stomach. Patients are advised not to eat, drink, or take other medicines for at least 30 minutes afterward. Thus, one must follow what is being prescribed for the best result, as the administering of the pill could vary based on the medication.

Most importantly, a healthy balanced diet, and a regular workout routine is also important will the person is on the pill.

What Are The Side Effects Of Wegovy Pill?

Digestive problems such as nausea and vomiting remain the most common side effects of GLP-1 drugs. These issues were also reported in studies of the pill versions. Around 7 percent of participants taking the Wegovy pill stopped treatment because of side effects, compared with 6 percent in the placebo group. In orforglipron’s trial, up to 10 percent of patients discontinued treatment, compared with 3 percent on placebo.

One key difference lies in how the medications are used. The Wegovy pill must be taken on an empty stomach with a small amount of water. Patients are advised not to eat, drink, or take other medicines for at least 30 minutes afterward. Doctors say this requirement has limited the use of Rybelsus, the pill form of semaglutide approved for diabetes, compared with Ozempic.

Eli Lilly highlights that orforglipron was taken once daily in trials without restrictions on food or water, which may make it easier for patients to use consistently.

Women Heart Symptoms Could Differ From Men, Explains Expert

Updated Feb 14, 2026 | 08:11 PM IST

SummaryHeart disease is the leading cause of death in women, yet symptoms often differ from men and go unnoticed. Experts urge greater awareness of hormonal changes, reproductive aging, and earlier screening to prevent avoidable deaths.

On February 13, Canadians across the country mark Wear Red Canada Day, a reminder that heart disease remains the leading cause of death for women. Yet despite the scale of the problem, many women still do not recognize their risk or their symptoms.

“We’re learning more and more each day about how heart disease uniquely affects women,” said nurse practitioner and researcher Rachel Ollivier in an interview with CTV News. She emphasized that awareness is still lagging, both among patients and within health-care systems.

According to the World Health Organization, cardiovascular disease accounts for roughly one in three deaths among women globally. In Canada, heart disease and stroke continue to be leading causes of death among women, and women are less likely than men to receive timely diagnosis or treatment.

Symptoms Can Look Different

Chest pain remains the most common heart attack symptom in both men and women. But Ollivier explained that women’s symptoms can often be subtler or feel different.

“For women, they often uniquely experience chest pain that seems like more of a discomfort or a tightness in the chest,” she said. Some women may feel pain in the left arm or jaw, unusual fatigue, nausea, vomiting, or discomfort between the shoulder blades.

Because these symptoms can be less specific, they are sometimes dismissed as stress, anxiety, indigestion, or exhaustion. Social factors also play a role. Women often juggle multiple responsibilities at home and work, and may delay seeking care. In some cases, their concerns may also be minimized within health-care settings.

Medical differences matter too. Women typically have smaller hearts and arteries, and plaque buildup behaves differently compared to men. Conditions such as spontaneous coronary artery dissection and microvascular dysfunction are seen more commonly in women, making diagnosis more complex.

Hormones and the Hidden Risk Window

Beyond symptoms, experts are urging greater recognition of the role hormones play in lifelong heart health.

“Endogenous estrogen is cardio protective,” Ollivier explained. As women enter the perimenopausal transition, estrogen levels fluctuate and gradually decline, and that protection is lost. This shift can lead to higher cholesterol levels and changes in fat distribution, increasing cardiovascular risk, particularly between the ages of 40 and 60.

Colleen Norris, a nursing professor at the University of Alberta and research lead of the CKHui LHHW Women’s Heart Health Research Collaborative who wrote on Yahoo Canada, believes the conversation needs to go even deeper.

She argues that ovaries have long been viewed only through the lens of reproduction. “The ovaries are not just reproductive organs. They are architects of women’s health across the lifespan,” she noted. Estrogen influences the heart and blood vessels, but also the brain, bones, kidneys, metabolism, and immune function.

Most women are never told that ovarian reserve and estrogen levels begin declining in their late 30s. By the time noticeable symptoms appear, biological changes may have already been underway for years.

Menopause itself is just one day, Norris explained. The larger reproductive transition surrounding it is what significantly increases vulnerability to chronic disease. Yet the health-care system often waits until disease develops before intervening.

Moving From Awareness to Action

Both experts stress that education is critical. Women with conditions such as polycystic ovary syndrome, pregnancy complications like preeclampsia or gestational diabetes, and those entering midlife should be particularly mindful of their cardiovascular risk.

Wear Red Canada Day is meant to spark awareness, but symbols alone are not enough. Experts are calling for better research funding focused on midlife women, improved medical education around ovarian aging, and more proactive screening during the reproductive transition.

Heart disease in women is not inevitable. But recognizing that symptoms can differ, and that hormonal shifts matter, could be lifesaving.
