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.
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.
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.
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:
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.
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.
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.
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.
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.

Kerala has recently seen a sharp increase in hepatitis A cases, drawing national attention after media reports revealed more than 31,000 infections and 82 deaths recorded by the end of December 2025, according to NDTV. The World Health Organization (WHO) states that Hepatitis A leads to mild or severe illness in around 1.4 million people each year, while nearly 113 million individuals get infected without showing symptoms. Globally, the disease claimed an estimated 7,134 lives in 2016. With numbers climbing in Kerala, here is a closer look at what hepatitis A is, how it spreads, and the precautions people should take.
Kerala has reported its highest number of hepatitis A cases so far, raising renewed worries around drinking water quality, sanitation standards, and disease monitoring. As per The Hindu, the state logged 31,536 confirmed and suspected cases along with 82 deaths as of December 30, 2025. Health specialists say the outbreak did not happen overnight. It reflects long-standing pressure on early detection systems, sanitation facilities, and public water supply networks. Since Hepatitis A tends to be more severe in older age groups, the growing number of infections among adolescents and adults has become a major concern.
Hepatitis A is a viral infection of the liver caused by the hepatitis A virus (HAV). It spreads mainly through contaminated food or water, or close personal contact with an infected person. The infection can cause liver inflammation, jaundice, extreme tiredness, and stomach pain. In most cases, it is a short-term illness that clears on its own without specific treatment, though severe cases can occur. Unlike hepatitis B or C, hepatitis A does not lead to long-term liver damage. The WHO notes that vaccination remains the most reliable way to stay protected.
Symptoms of hepatitis A usually show up a few weeks after exposure to the virus, though some people never develop noticeable signs. According to the Cleveland Clinic, those who do may experience:
These symptoms are often mild and disappear within weeks. In some cases, however, the illness can be intense and last for several months.
Kerala has faced several hepatitis A outbreaks in recent years, but the current rise is notable for its scale and severity. Reports cited by The Hindu link the spread to contaminated groundwater, poor sanitation, and unhygienic surroundings, particularly in crowded localities. Investigations suggest that inadequate environmental hygiene and unsafe water sources have played a key role in allowing the virus to spread more widely.
Yes, prevention is possible. The Cleveland Clinic states that vaccination against hepatitis A is the simplest and most effective safeguard. Doctors recommend the vaccine for children older than 12 months and for adults who:
Basic hygiene also goes a long way in preventing infection. Regular handwashing and careful food handling can reduce the risk significantly. Outbreaks often worsen when simple safety habits are ignored. Small daily choices can protect your liver. Drinking boiled or bottled water, avoiding food from unhygienic sources, and peeling fruits at home can help lower the risk.
If someone in the household is infected, cleanliness becomes even more important. Surfaces should be disinfected, food prepared carefully, and personal items not shared. Safe sexual practices also matter, as the virus can spread through oral-anal contact. On a broader level, preventing future outbreaks requires more than short-term fixes. Improving water quality, repairing sewage systems, and strengthening public health surveillance are essential to stop the cycle from repeating.

What looks like a simple biological process of being born, living, and then dying, may have another layer that not many know. Between life and death, your cells could be conscious, or what scientists call "third state of life".
Human body is made of 30 trillion human cells and microbes. They all function together to maintain life. Research show that in the near death experience, there may be a "third state of life". What does it mean? It means that cells are able to continue and in fact, reorganize even after an organism dies. Does it mean that human consciousness also does the same even when we are not aware?
There are reports of survivors of near-death experiences who see vivid dream. These are tunnel vision of light, or a feeling of calm. But, what happens to those who do not come back? Could their cells be undergoing a change and also be reorganized in ways we do not understand?
This concept gained momentum with the emergence of xenobots, which is AI-created multicellular creatures that exhibit autonomy outside their initial biological purpose. These mall biological robots are constructed from frog embryo cells, which, when introduced into new environments, spontaneously reconfigure and assume new functions. For instance, instead of employing their hair-like cilia to move mucus as they would in a living frog, xenobots redirect these structures for mobility.
This phenomenon proves that cells are capable of being reassembled into new shapes and functions even after the death of an organism. Researchers opine that this postmortem cellular plasticity is not exclusive to xenobots. Human cells, or "anthrobots," also display such actions, proving the ability for posthumous cellular reorganization and transformation.
At the heart of the debate is a provocative question: can cells be conscious? Physician and evolutionary biologist William Miller explores this idea in The Sentient Cell, where he argues that cells possess a basic form of awareness. His Cellular Basis of Consciousness (CBC) hypothesis suggests that cells don’t simply follow genetic instructions on autopilot. Instead, they can make decisions, adapt to changing conditions, and act to preserve themselves, traits that resemble a primitive kind of consciousness.
This challenges the traditional view of genes as the sole masters of biology. Miller proposes that genes function more like tools, while intelligent cellular behavior drives cooperation, mutual support, and problem-solving. In this view, life evolves not just through “survival of the fittest,” but through collaboration and adaptability.
Historically, death has been defined as irreversible loss of organismal biological activity. Yet such medical procedures as organ donation illustrate that some organs, tissues, and cells maintain their functional properties even after death—sometimes for hours, days, or weeks under optimal circumstances.
A number of factors will decide whether cells survive after death. Environmental parameters, the state of metabolism, and methods of preservation are all important. Human white blood cells, for instance, can last between 60 and 86 hours from the time of death, while those of mice skeletal muscle can regenerate two weeks after death. Some fibroblast cells in sheep and goats have even been grown up to a month following the organism's death.
In addition, researchers have discovered that certain human lung cells are capable of self-assembling into small multicellular structures that can move and heal themselves. These "anthrobots" exhibit a capacity to explore their environment and repair injured neurons, abilities that contradict traditional assumptions about cellular behavior following death.

If flu symptoms such as fever, chills, coughing, a sore throat or a pounding headache start to creep in, many people assume the best option is to stay in bed and let it pass.
But even if you have managed the flu on your own in the past, this time it may be worth calling your doctor. That’s because antiviral flu medicines, including Tamiflu, can sometimes make a real difference.
Certain prescription drugs can shorten how long the flu lasts and lower the risk of serious complications, but timing is critical. Here’s how to work out whether flu antivirals could help you or someone close to you.
Flu antivirals are prescription medicines designed to help the body fight off the influenza virus. “They work by stopping the flu virus from multiplying and spreading through the body. Influenza is the virus that causes the flu,” explained Deon Pilkington, PharmD, a clinical pharmacy coordinator as per Banner Health.
These medications do not cure the flu, but they may:
All flu antivirals require a prescription and are most effective when started within the first one to two days after symptoms appear. That’s why reaching out to a healthcare provider early can matter.
Antibiotics should not be used to treat the flu. “Because influenza is caused by a virus, antibiotics won’t help,” said Mallory Yan, PharmD, a pharmacist with Banner Health.
Not everyone who gets the flu needs prescription treatment. “These medications are generally reserved for people who have confirmed flu and are at higher risk for complications,” Dr. Pilkington said.
You should contact a doctor promptly if you or someone you care for falls into one of these categories:
Even healthy individuals may be prescribed antivirals if they live with someone at high risk. Limiting the spread of flu in households where complications could be serious is important.
If you are at higher risk, it’s best to contact your doctor as soon as flu symptoms begin. Starting treatment within 48 hours offers the greatest benefit.
Warning signs may include:
If you test positive for flu or feel seriously unwell, do not delay. Beginning antiviral treatment within the first two days gives you the best chance of recovering faster and avoiding complications.
If you’re wondering, “Do I need Tamiflu?” remember that flu antivirals are most helpful when taken early, ideally within the first day or two after symptoms begin. Acting quickly can change how the illness unfolds.
