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.

When Back Pain Isn’t Just Back Pain: Recognising Warning Signs of Kidney Cancer

Updated Jun 16, 2026 | 05:00 PM IST

SummaryWhen uncertainty exists, simple tests such as a urine examination and ultrasound can provide clarity. Early detection remains the key to effective treatment and significantly better outcomes.

Back pain is one of the most common health complaints worldwide, affecting a large proportion of adults at some point in their lives. In most cases, it is caused by benign musculoskeletal issues such as muscle strain, poor posture, or disc-related problems, and it tends to improve with rest, physiotherapy, or simple medication. However, not all back pain originates from the spine. In some situations, pain felt in the lower back or flank region may be linked to underlying kidney conditions, including kidney cancer. As renal cell carcinoma often progresses silently in its early stages, symptoms may be delayed, making it important to recognise when back pain is unusual.

Why Kidney Cancer Can Cause Back Pain

Dr Raj Nagarkar, Chief Surgical Oncologist at HCG Manavata Cancer Centre, Nashik, said, "The kidneys are located deep in the upper abdomen, on either side of the spine, just below the rib cage. When a tumour develops in this region, it can cause pain through several mechanisms. As the tumour grows, it may stretch the kidney’s outer fibrous capsule, leading to a persistent, dull ache in the flank area between the ribs and hip. In some cases, fragile tumour blood vessels may bleed internally or form clots that obstruct urine flow, resulting in sudden, sharp pain that can resemble renal colic. Larger tumours may also press on surrounding nerves or structures, producing discomfort that may be mistaken for back or abdominal pain."

Unlike musculoskeletal pain, which typically improves with movement or rest, kidney-related pain is often constant, may worsen at night, and does not respond well to routine pain relief or physiotherapy.

Red Flags When Back Pain Needs Further Diagnosis

While back pain alone is rarely a sign of kidney cancer, certain accompanying symptoms should raise concern. One of the most important warning signs is blood in the urine, which may appear pink, red, or dark brown and can sometimes be intermittent. Persistent flank pain associated with a palpable mass under the ribs may indicate more advanced disease. Unexplained weight loss, ongoing fatigue, or a general sense of weakness can reflect systemic illness. Some patients may experience intermittent fever without infection, new-onset high blood pressure, or swelling in the legs and ankles due to impaired venous drainage. Anaemia-related symptoms such as dizziness, breathlessness, or pallor may also be present. When back pain persists beyond a few weeks and is accompanied by any of these features, further medical evaluation is strongly recommended.

Differentiating Musculoskeletal Back Pain from Kidney Cancer Pain

It is also important to distinguish kidney-related pain from common musculoskeletal back pain. Mechanical back pain is usually localised to the lower back, may radiate to the legs, and often begins after physical strain or injury. It tends to improve with rest, heat application, or physiotherapy. In contrast, kidney cancer pain is typically one-sided, located higher in the flank below the ribs, and develops gradually without a clear trigger. It is often persistent, may disturb sleep, and is not relieved by standard pain management approaches. Unlike spinal pain, it is more likely to be associated with systemic symptoms such as haematuria, weight loss, or fatigue.

Who Is at Higher Risk?

Certain individuals are at higher risk of developing kidney cancer and should be particularly attentive to persistent flank pain. Risk factors include smoking, which significantly increases exposure to kidney-damaging toxins, obesity, long-standing hypertension, chronic kidney disease or dialysis, and a family history of kidney cancer or genetic conditions such as von Hippel-Lindau disease. Occupational exposure to industrial chemicals like trichloroethylene or cadmium may also contribute to risk. When multiple risk factors are present, even mild or persistent symptoms should not be ignored.

Diagnosing Kidney Cancer

If warning signs are suspected, doctors typically begin evaluation with simple and non-invasive tests. A urine analysis can detect microscopic or visible blood, while blood tests help assess kidney function, anaemia, and calcium levels. Imaging plays a crucial role, with ultrasound often used as the first-line investigation, followed by a contrast-enhanced CT scan for detailed evaluation of tumour size and spread. In selected cases, a biopsy may be performed, although it is not always required before treatment.

Treatment and Outcomes

Treatment outcomes for kidney cancer have improved significantly in recent years. In early-stage disease, partial nephrectomy allows removal of the tumour while preserving healthy kidney tissue, often using minimally invasive or robotic techniques that support faster recovery. In more advanced cases, targeted therapies and immunotherapy help control disease progression and improve quality of life, with many patients able to maintain daily activities during treatment. For small, slow-growing tumours in selected individuals, active surveillance may be an appropriate option.

Listening to the Warning Signs

While most back pain is benign and related to musculoskeletal causes, persistent or unusual pain, especially when accompanied by symptoms such as blood in the urine, unexplained weight loss, or systemic changes, should not be ignored. Kidney cancer often develops silently, and early signs can be subtle. Unlike muscular pain, which is typically movement-related and self-limiting, kidney-related pain is deeper, more persistent, and often associated with other warning features.

Vanessa Trump Begins Second Stage of Breast Cancer Treatment

Updated Jun 16, 2026 | 06:00 PM IST

SummaryBreast cancer is also the leading cause of cancer mortality among women worldwide and the most common cancer diagnosed overall, accounting for approximately 2.3 million new cases and 670,000 deaths annually, according to the WHO

Vanessa Trump, the former wife of Donald Trump Jr., has announced that she is beginning the second stage of her breast cancer treatment.

In an Instagram post, Trump said she has spent the past four weeks recovering from surgery.

She said she was “grateful to be healing and moving forward.” “Sending love, strength, and hope to everyone fighting this battle,” she wrote.

The 48-year-old mother of five first revealed her breast cancer diagnosis in late May, saying she was working closely with her medical team to develop a treatment plan.

However, Vanessa Trump has not disclosed the type of breast cancer she has been diagnosed with or provided details about the next phase of her treatment.

What Is Breast Cancer?

Breast Cancer occurs when abnormal cells in the breast grow uncontrollably, often beginning in the milk ducts or lobules. It remains the most commonly diagnosed cancer among women worldwide.

Breast cancer is also the leading cause of cancer mortality among women worldwide and the most common cancer diagnosed overall, accounting for approximately 2.3 million new cases and 670,000 deaths annually, according to the World Health Organization.

Every year, breast cancer accounts for about 30% of all new cancer cases in US women. The average risk of a woman in the US developing breast cancer sometime in her life is about 13 per cent.

A recent study published in The Lancet Oncology projected that global breast cancer cases could rise to more than 3.5 million annually by 2050.

Major Lifestyle Risk Factors

In 2023, 28 percent of the global breast cancer burden (6.8 million years of healthy life lost to disability, illness, and early death) was linked to six potentially modifiable risk factors.

These include:

  • High red meat consumption
  • Tobacco use and second-hand smoke exposure
  • High blood sugar levels
  • High body mass index (BMI)
  • Excessive alcohol use
  • Low physical activity

Breast cancer patients who are also obese or have type 2 diabetes experience more aggressive cancer growth and worse outcomes. Prior studies have shown that weight loss treatment and surgery following a breast cancer diagnosis are associated with improved heart health and increased survival.

Tips For Maintaining Breast Health

Regular checkups are the cornerstone of early breast cancer detection.

According to the World Health Organization (WHO), early identification of breast abnormalities greatly increases the chances of effective treatment and survival.

  • Women who ignore screenings may face delayed diagnosis, which can complicate treatment.
  • Schedule regular mammograms and clinical breast exams
  • Perform monthly self-examinations
  • Know your family medical history
  • Maintain a healthy weight and active lifestyle
  • Pay attention to hormonal health
  • Watch for physical changes such as persistent pain, swelling, or skin dimpling.
