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.

Supreme Court Declares Menstrual Hygiene As Part Of Right To Life: Here Are the Directions

A bench comprising Justice JB Pardiwala and Justice R Mahadevan passed the following directions:

  • All States/UT must ensure that every school, whether government-run or privately managed, in both urban and rural areas, is provided with functional gender segregated toilets with usable water connectivity.
  • All existing or newly constructed toilets in schools shall be designed, constructed and maintained to ensure privacy and accessibility, including by catering to needs of children with disabilities.
  • All school toilets must be equipped with functional washing facilities and soap and water available at all times.
  • All states/UTs must ensure that every school, whether government-run or privately managed, in both urban and rural areas, provide oxo-biodegradable sanitary napkins manufactured in compliance with the ASTM D-6954 standards free of cost. Such sanitary napkins must be made readily accessible to girl students, preferably within toilet premises through sanitary napkin vending machines or, where not visible, at a designated place.
  • All States/UTs must ensure that every school, whether government-run or privately managed, in both urban and rural areas establish menstrual hygiene management corners. It must be equipped with spare innerwears, uniforms, disposable pads and other necessary materials to address menstrual urgency.

The court also issued directions for the disposal of sanitary waste. Justice Pardiwala said, "This pronouncement is not just for stakeholders of the legal system. It is also meant for classrooms where girls hesitate to ask for help. It is for teachers who want to help but are restrained due to a lack of resources. And it is for parents who may not realise the impact of their silence and for society to establish its progress as a measure in how we protect the most vulnerable. We wish to communicate to every girlchild who may have become a victim of absenteeism because her body was perceived as a burden when the fault is not hers."

Why Is This Judgment So Important?

In India, menstruation is still seen as taboo. In fact, there is a lot of shame around it. Menstrual shame is the deeply internalized stigma, embarrassment, and negative perception surrounding menstruation, which causes individuals to feel unclean, or "less than" for a natural biological process. This judgment thus is an effort to do away with the shame rooted in cultural, social, and religious taboos, which is often the reason why many girls drop out, or due to lack of awareness, develop health adversities.

Most Medical Videos Even By Doctors Online Are Factually Incorrect, Finds Study

Updated Jan 31, 2026 | 12:13 PM IST

SummaryA JAMA Network Open study found most popular YouTube health videos, including those by doctors, lack strong scientific backing. Reviewing 309 cancer and diabetes videos, researchers found nearly two-thirds had weak or no evidence, while poorly supported content attracted more views than evidence-based videos.

Most health videos on YouTube, even those made by doctors are also not reliable medical information, found a new study, published in JAMA Network Open. The researchers reviewed 309 popular YouTube videos on cancer and diabetes and found that fewer than 1 in 5 were supported by high quality scientific evidence. About two-thirds of the view had low, very low or no evidence at all to back up their health claims.

What was more concerning is that weaker evidence often attracted more viewer than those backed with strong science. The study looked at videos which had at least 10,000 views. The lead author of the study Dr EunKyo Kang of South Korea's National Cancer Center, said, "This reveals a substantial credibility-evidence gap in medical content videos, where physician authority frequently legitimizes claims lacking robust empirical support."

"Our findings underscore the necessity for evidence-based content-creation guidelines, enhanced science communication training for health care professionals, and algorithmic reforms prioritizing scientific rigor alongside engagement metrics," Kang added in a news release.

How Was The Study Conducted?

The researchers reviewed videos from June 20 and 21, 2025, focusing on cancer and diabetes content. 75 per cent of them were made by physicians. The videos had a median count of 164,000 views and a median length of 19 minutes.

Researchers also developed a scoring system, called E-GRADE to rate the strength of science backed evidence in each video's claim.

This is how the grading system worked:

  • GRADE A: high quality evidence
  • GRADE B: standard quality evidence
  • GRADE C: low quality evidence
  • GRADE D: very low or no evidence

What Were The Results Of The Medical Videos?

  • GRADE A: 19.7%
  • GRABE B: 14.6%
  • GRADE C: 3.2%
  • GRADE D: 62.5%

The study also found that videos with the weakest evidence were 35% more likely to get higher views than videos with strong scientific evidence.

Richard Saver, a professor of law at the University of North Carolina at Chapel Hill noted that this issue is not just limited to YouTube. "Physician-spread misinformation is a long-standing problem, dating back well before the internet era," he wrote in an accompanying editorial.

Saver said some doctors continue to lean on personal experience rather than solid data, despite evidence-based medicine being regarded as the gold standard. He noted that EBM can feel like it downplays individual clinical judgment. Still, Saver stressed that more research is needed, adding that the study underscores the importance of examining the evidence behind health professionals’ claims on social media.

Menopause Clinics Explained: Latest Launch By Maharashtra And Kerala Government

Updated Jan 30, 2026 | 11:00 PM IST

SummaryThe WHO has flagged menopause as an overlooked health priority, prompting Maharashtra and Kerala to launch government-run menopause clinics. These clinics offer integrated care including medical consultations, mental health support, screenings and lifestyle guidance, aiming to provide holistic, stigma-free menopause care within the public health system.

The World Health Organization (WHO) noted that menopause often goes unnoticed as a clinical priority, observing these unmet needs, the state governments in Maharashtra and Kerala will soon launch government-run menopause clinics. These clinics will have specialized support systems designed to offer holistic healthcare services for menopausal women within the public system.

These clinics will also have medical consultations, mental health counselling, targeted screening services and lifestyle guidance.

What Are Menopause Clinics?

Menopause clinics are specialized healthcare units, usually housed in government hospitals, urban health centres or district hospitals, that focus on both the medical and emotional needs of women transitioning through menopause. Rather than brushing menopause aside as a “natural” phase that needs little attention, these clinics offer organized, evidence-based care that goes well beyond routine outpatient visits.

At the heart of a menopause clinic is a comprehensive, integrated approach that includes:

  • Clinical assessment of menopausal symptoms
  • Screening for hormonal and physical health issues, such as bone health and heart disease risk
  • Mental health support and psychosocial counselling
  • Personalized advice on lifestyle, nutrition and mid-life wellness
  • Ongoing patient education and structured follow-up

By bringing these services together under one roof, menopause clinics help women cope with day-to-day symptoms while also addressing long-term risks like osteoporosis, metabolic changes and a higher likelihood of cardiovascular disease.

What Is Menopause?

This is the natural, permanent end of menstruation defined as 12 consecutive months without a period. This typically occurs between ages 45 to 55.

Foods That May Help During Menopause

  • Soy: A top source of phytoestrogens, particularly isoflavones, which bind to estrogen receptors in your body. Studies suggest soy may help alleviate hot flashes, improve cholesterol levels, and even reduce the risk of heart disease during menopause.
  • Flaxseed: Packed with lignans, a type of phytoestrogen with mild estrogenic effects, flaxseed may also offer some relief.

Including these foods in your diet could help ease symptoms and reduce your risk of certain menopause-related conditions.

Why a Balanced Diet Matters

A nutrient-packed, balanced diet is the foundation of good health at any age. Prioritize:

  • Vegetables and fruits: Rich in vitamins and antioxidants.
  • Whole grains: Great for maintaining steady blood sugar levels.
  • Lean proteins: Support muscle health and repair.
  • Low-fat dairy: Provides calcium for bone strength.
  • Avoid ultra-processed junk foods, excessive sugar, and unhealthy fats, which contribute little beyond empty calories.

Maharashtra Menopause Clinic

Earlier this January, the Maharashtra government rolled out the country’s first state-run menopause clinics across government hospitals and urban health facilities. The initiative was launched on Makar Sankranti, January 14, under the guidance of Minister of State for Health Meghna Bordikar.

As per official statements, these clinics are designed to offer end-to-end care in one place. Services include expert medical consultations to evaluate and manage menopausal symptoms, mental health support to address emotional and psychological concerns, and screenings for bone health, cardiovascular risk and hormonal balance. Medicines and follow-up advice are also provided during the same visit, cutting down the need for multiple referrals and repeat hospital trips.

A senior health official pointed out that while menopause is a natural life stage and not a disease, many women need consistent physical and emotional support during this transition. The strong response from women across Maharashtra highlights a long-standing gap in healthcare, where menopause-related concerns often went unaddressed due to the absence of dedicated services. With this move, Maharashtra has also set an example for other states looking to introduce gender-specific care within public health systems.

Kerala follows with dedicated clinics

Taking a cue from Maharashtra, the Kerala government has announced plans to set up specialized menopause clinics in district hospitals. An initial allocation of Rs 3 crore has been earmarked for the project in the 2026 state budget, presented by Finance Minister K N Balagopal.

The proposed clinics in Kerala will follow a similar model, offering medical consultations for menopausal symptoms, mental health counselling, and screenings for heart, bone and hormonal health. Women will also receive medicines along with lifestyle and dietary advice at a single facility.

The initiative acknowledges the wide-ranging impact of menopause, including hormonal changes, sleep disturbances, bone health issues and increased stress, and aims to create a one-stop support system within district hospitals. By bringing menopause care into mainstream public healthcare, Kerala hopes to improve access, reduce stigma and ensure that women receive timely, structured support during this phase of life.
