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.

Priyanka Chopra and Nick Jonas, we all know them as a power couple. However, there are moments that have broken them and they both have talked about it. This was the moment of their daughter Malti Marie Chopra Jonas' birth.
On February 4 episode of the Jay Shetty Podcast, Jonas, 33, opened up about his daughter's birth. "She came to the world under sort of very intense circumstances, which I have not really talked about ever. She came out, she was one pound and 11 ounces, and purple basically. These angels at the NICU kind of resuscitated her in that moment, got her taken care of really quickly, and intubated and everything else."

In fact, recently a video has been circulating of Priyanka Chopra Jonas talking about the premature birth of her daughter too. She described this period as "tough" and said that it was extremely hard on her. She also called Malti a "miracle baby".
On the Jay Shetty podcast, she revealed that the couple were forced to announce her birth, whereas they wanted to wait till her health gets better. They had put everything on halt and visited the NICU every single day. "We received a text saying that her (Malti) birth would be out in the newspapers, if we don't, they are going to put it in within three hours. So we were kind of forced into announcing her birth because we wanted to control our own narrative. We weren't ready. We didn't know what would happen with her or how she would be."
Priyanka shared that she was informed about her premature delivery in the 27th week. This is what made her completely "shut down". She also recalled sitting in front of the fireplace for nine hours and was not able to process the situation.
Like Jonas, Priyanka too noted that Malti was purple at birth and required immediate NICU attention. She also said that the nurses' fingers were too big for her small mouth. She recalled feeling "numb" at that time.
However, Jonas shared that Priyanka and him "had a lot of tough conversations day in, day out about caring" for Malti. He also appreciated his wife's strength on handling the situation. "The way in which she handled it was so inspiring to me, and you know, allowing for those days to be tough, but to be tougher for our little girl was the focus."
Malti received six blood transfusions and gained weight in the hospital. After nearly three and half months, she was able to go home.
Priyanka reveals that in her house there is a "big mandir" with "a large Shiv Ji murti". This is where everyone sat as a family and she cried not out of fear, but out of gratitude. "Gratitude that she survived, that she was home, that she chose us, and that we were able to make it happen. IVF is tough."
Read: What Parents of Premature Babies Must Know About the NICU, According to a Neonatologist
Health and Me had earlier spoken to Dr Sanjay Wazir, Medical Director, Neonatology and Pediatrics at Motherhood Hospitals, Gurugram who pointed out that Neonatal Intensive Care Unit or the NICU may seem overwhelming, however, it must be seen as a sanctuary of healing.
"In the NICU, premature or unwell newborns receive specialized medical attention, constant monitoring, and compassionate care from expert hands. Here, the mother and the baby are well taken care of. This will help the baby lead a healthy life. Hence, NICU care is important for all the premature or unwell babies," he says.
The doctor explains that the NICU provides a controlled and nurturing environment where babies can grow stronger outside the womb. "It helps maintain their body temperature, supports breathing, and ensures proper nutrition through feeding tubes if necessary," he says.
Every machine in the NICU is for a specific purpose, right from oxygen support to heart rate monitoring, ensuring that each baby receives precisely what they need. Parents often find comfort knowing that the experts in the NICU are constantly watching over their child’s progress, explains the doctor.
The doctor points out that parents are essential part of the NICU journey. "Your touch, your voice, and your calm presence can help your baby feel safe and comforted," he tells to all the parents. However, what is extremely important is to maintain hygiene guidelines, staying involved in daily care, and communicating regularly with the doctors and nurses to "strengthen your bond and confidence as caregivers." The doctor says that during this time, the mother will also be taught about Kangaroo care, which is skin-to-skin contact that helps the mother bond with her baby.

Cases of scrub typhus, one of the deadliest infections affecting multiple organs, or even death, have significantly increased from previous year. Once relevant to people working in fields, new studies show it migrating to human settlements.
In 2025, Andhra Pradesh reported 1,566 scrub typhus cases, and nine suspected deaths, according to data from the Integrated Health Information Platform, Integrated Disease Surveillance Programme (IDSP-IHIP) on 8 December. Followed by Karnataka with 1,870 cases, Tamil Nadu 7,308 cases, and Telangana, 309 cases.
Scrub typhus, also known as bush typhus, is a bacterial infection caused by bacteria infection, caused by bacterium Orientia tsutsugamushi. It is spread through bites of infected larval mites, Chiggers.
Most cases of scrub typhus occur in rural areas of Southeast Asia, Indonesia, China, Japan, the Indian subcontinent and northern Australia. Until now, it was believed that chiggers only lurked in the tall grasses of remote paddy fields or dense forests. Due to this, it is commonly known as "farmers' disease", only confined to the fields.
However, new PLOS study data revealed the opposite. The study is led by researchers from Christian Medical College (CMC) Vellore and international collaborators and suggests that the bulk of infections are now even occurring within human settlements.
The study monitored over 32 000 people in Tamil Nadu, which led to the conclusion that agricultural activities, long considered the primary risk factor, were only weakly associated with the disease in high-prevalence areas.
Risk for scrub typhus is significantly higher for those living in clustered houses or homes with fewer rooms. If the micro environment around the residence is unmaintained, gardens are patched, or even the damp corners of a courtyard, it could lead to breeding ground for the mites and the rodents that carry Chiggers.
It was once believed that working-age men were the most affected, but the new study tells otherwise. According to the new data, women over 60 are at the highest risk of infection.
As women spend most of their time in and around the home, due to household work, from the kitchen to the laundry, these activities are now the primary cross point of contact with infected mites.
As initial symptoms of infection, such as fever, headache, and muscle pain, are the same as viral flu or dengue, many first seek help from untrained practitioners or local pharmacies.
By the time they reach the hospital, the disease has already progressed to severe complications like acute respiratory distress syndrome (ARDS), Kidney failure, or Meningoencephalitis, which is inflammation of your meninges and brain at the same time, a life-threatening condition.
Not only this, the researchers revealed that nearly 10 percent of affected households exceed 25 percent of their income in the treatment.
For severe cases, the cost of treatment can be up to approximately INR 110,000, a staggering sum for rural and peri-urban families earning a fraction of that monthly.
Early intervention is necessary, as if a fever lasts more than two days, don't just treat it as "seasonal fever".
Consult a qualified doctor and specifically ask about scrub typhus. Infection can be treated with doxycycline common antibiotic, in the early stages. The case fatality rate in this study was 1.5 percent, hospital based studies in South India have previously recorded mortality rates as high 30 percent when treatment is delayed
