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.

Endometriosis Taught Me To Always Listen To My Body, Says Model Padma Lakshmi

Updated Apr 2, 2026 | 05:00 PM IST

SummaryThe 55-year-old, Co-founder of Endometriosis Foundation of America, said that the condition made her understand how strong she is and called for greater awareness and self-advocacy among women.

The World Health Organization estimates that 10 percent (190 million) of reproductive-age women worldwide suffer from endometriosis.

The chronic and complex menstrual disease that affects many women is characterized by severe pain during menstruation, heavy menstrual bleeding, chronic pelvic pain (pain that does not go away when the menstrual cycle ends), infertility, and abdominal bloating and nausea.

The incurable condition poses a significant challenge to women as it affects their personal and professional lives, relationships, and fertility, among others, due to persistent pain and fatigue.

The diagnosis also gets delayed, as endometriosis is often confused with PCOS, or Polycystic Ovary Syndrome, due to some overlapping symptoms like irregular menstrual periods. The symptoms may continue to persist or recur after treatment is initiated.

In a powerful statement resonating with millions worldwide, Indian American author and television host Padma Lakshmi has shared her experience with the condition.

Opening about her personal battle with endometriosis, the 55-year-old, Co-founder of Endometriosis Foundation of America, said that the condition made her understand how strong she is and called for greater awareness and self-advocacy among women.

"Endometriosis has taught me that I should always listen to my body. Pain is your body's way of telling you something is wrong,” said Lakshmi, in a media post on social media platform Instagram.

"Through my struggles with endometriosis, I've learned that, actually, I have a very high threshold for pain, that I may be stronger than I know, but that I shouldn't always need to be,” PopSugar quoted her as saying.

Lakshmi noted that it is now her life's mission "to advocate for my own health, and also to advocate for all women with endometriosis."

What Is Endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining.

Endometriosis affects many women and can impact their daily lives, including their ability to work comfortably. Many women continue their professional responsibilities despite experiencing severe discomfort, fatigue, and pain.

Raising awareness about the condition and encouraging supportive workplaces can help women manage both their health and career more effectively.

Since it is a progressive disorder, timely intervention remains key to managing it. In many cases, women live with symptoms for several years before receiving the correct diagnosis, which can delay treatment and affect their quality of life.

Treating Endometriosis

Treatment is particularly based on the severity of symptoms. Women will be advised lifestyle modifications such as regular exercise, stress management, and an anti-inflammatory diet. Non-steroidal anti-inflammatory drugs may help reduce discomfort.

Hormonal therapies may also be used to control symptoms. Some women will be advised to undergo laparoscopy to remove endometriotic cysts.

Minimally invasive surgery can help remove lesions and restore pelvic anatomy, which may also improve fertility in some cases. In advanced cases, surgery can be recommended to women.

What Is Herpes?

The herpes simplex virus (HSV) is very common, and the infection is lifelong. But the symptoms can come and go over different periods of life. Many people never get any symptoms linked to their infection.

The common virus, carried by up to 50 to 80 percent of adults, can cause painful blisters or ulcers. It primarily spreads by skin-to-skin contact. It is treatable but not curable.

There are two types of herpes simplex virus: HSV-1 and HSV-2.

HSV- 1 is the most common and usually spreads by oral contact. It causes infections in or around the mouth (such as oral herpes or cold sores), as well as genital herpes.

Common oral herpes symptoms include

  • blisters (cold sores)
  • open sores (ulcers) in or around the mouth or lips.

HSV-2 generally spreads by sexual contact and causes genital herpes.

Its symptoms include painful

  • bumps,
  • blisters,
  • open sores (ulcers) around the genitals or anus.

How Makeup Testers Can Spread Infection

Experts warned that makeup testers can become a breeding ground for germs. The repeated use of the open samples can spur their growth and can then spread by “double-dipping” — reusing an applicator after touching the skin. This can transfer viruses and bacteria between users.

“You can absolutely get a herpes infection from a makeup tester," Dr. Whitney Bowe, a dermatologist in New York City, told TODAY. "The more ‘double dipping’ that occurs, the higher the chance of spreading viruses or bacteria at a makeup counter.”

A 2010 study by researchers from Rowan University in New Jersey found that cosmetic samples harbored strep, E.coli, and staph.

For two years, the team examined makeup testers at makeup counters, specialty stores, and drug stores. They found that Saturday is the busiest day of the week, and 100 percent of the samples carried some sort of germ.

How To Stay Safe?

To reduce the risk of infection, experts recommend:

  • Much like the toothbrush, personal cosmetics and cosmetic brushes must not be shared.
  • Wash and dry your brushes regularly to avoid bacterial growth.
  • Avoid applying testers directly to your lips or skin
  • Use disposable applicators
  • Test products on your hand rather than your face
  • Avoid using testers if you have cuts, chapped lips, or active infections.

Why Inclusive Opportunities Matter For Individuals with Autism: Unlocking Untapped Potential

Updated Apr 2, 2026 | 08:00 AM IST

SummaryThis year’s theme of -Autism and Humanity- Every Life has Value” reiterates the need for inclusion of autism, ensuring equitable representation of these individuals. Ensuring that society not only recognizes them but also treats them with equal respect and dignity.

April 2 is celebrated worldwide as “Autism Awareness Day” and April as Autism month to create awareness and promote inclusivity and acceptance in society for individuals with autism.

So what exactly is Autism, and why do we need to create a culture of awareness and acceptance?

As per DSM V (Diagnostic and Statistical Manual of Mental Disorders) criteria, in simple terms, there is poor eye contact, impaired social communication skills, repetitive patterns (certain movements or fixation on certain toys, objects), difficulties with sensory processing - extreme sensitivity to sensory inputs (dislike loud noises, sensitive to touch), etc.

As a child, these individuals may not respond to name-calling, have poor eye contact/lack gestures like pointing, etc., lack imagination in play, and may not be able to relate and respond to the emotions of others. They have set routines and dislike changes to their routines. All this can cause significant disruption to their day-to-day functioning.

This year’s theme of -Autism and Humanity- Every Life has Value” reiterates the need for inclusion of autism, ensuring equitable representation of these individuals. Ensuring that society not only recognizes them but also treats them with equal respect and dignity.

Educational Support and Inclusive Workplace

Sarva Shiksha Abhiyan (SSA) was one of the Government's flagship programs, along with Action for Autism, to disseminate information in schools regarding inclusive education for autism. Education is a key foundation to ensure children with autism get suitable opportunities as adults. Special educators, with additional support in schools, can go a long way in ensuring their potential is maximized.

Many IT giants like Microsoft, Google, and SAP encourage tapping the potential of individuals with autism and their exceptional skills. In our country, organizations and NGOs, including Action for Autism, offer training for future employment opportunities.

There is a spectrum of Autistic Spectrum Disorders (ASD) known as Asperger’s syndrome, and these individuals have normal to above average intelligence and can have some exceptional skills, and the world includes some living examples of these with a higher IQ, some of whom are the most successful and famous personalities. Even on the other end of the spectrum, autistic individuals have exceptional skills, some of which include great attention to detail, creativity, problem-solving, and lateral out-of-the-box thinking.

Options for flexible working hours (part-time), understanding their need for routines, and explaining them beforehand regarding important changes to schedules can help them adapt better to an otherwise challenging workplace.

The Need For Sensitization

Understanding individuals with autism may need little extra support, being a little flexible with time deadlines, giving simple instructions, especially written/visual ones, and allowing them time to overcome their communication barriers can go a long way in ensuring they feel heard and valued like anyone else in the workplace.

Sensitization of all major organization employees to foster a culture of acceptance and awareness, and an accessible work environment, is the need of the hour. Autistic individuals do well in a variety of job profiles, including IT, technology, finance, art and creativity, and administration.

Environmental modifications like background noise cancellation with headphones help those with sensory processing issues. At the end of the day, none of us is perfect, it's recognizing our special skills and strengthening them.

Possibilities are endless if we wish to encourage and make these individuals heard. So, let’s carry the Autism Awareness Day beyond a mere day of awareness and light it up blue. Let’s value and acknowledge them being different, but also empower them to act on their special skills to earn them a dignified place in society and the workplace.
