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.

​Osteoporosis Affects Nearly 20% Of US Women Aged 50+: Why Screening Is Key

Updated Jul 13, 2026 | 12:14 PM IST

SummaryUpdated recommendations from the US Preventive Services Task Force (USPSTF) recommend that postmenopausal women younger than 65 undergo a risk assessment to determine whether they should receive a bone density scan.

Nearly one in five women aged 50 and older in the United States has osteoporosis, a bone disease that weakens bones and increases the risk of fractures. Yet many women remain undiagnosed because the condition often develops without noticeable symptoms in its early stages.

To improve early detection, the updated recommendations from the US Preventive Services Task Force (USPSTF) advise routine osteoporosis screening for women aged 65 years and older.

The task force also recommends that postmenopausal women younger than 65 undergo a risk assessment to determine whether they should receive a bone density scan.

The USPSTF recommends:

  • Women aged 65 years and older should undergo routine screening with a bone density scan.
  • Postmenopausal women younger than 65 should first complete a risk assessment questionnaire to determine whether a bone density scan is needed.

Women under 65 may need screening if they have one or more risk factors, including:

  • Low body weight
  • Family history of hip fractures
  • Cigarette smoking
  • Excessive alcohol consumption

"Screening is important because osteoporosis causes bones to become weaker and fracture more easily, leading to disability, chronic pain, loss of independence, and even death,” said Task Force member Dr. Esa Davis, professor of family and community medicine at the University of Maryland, Baltimore, NBC reported.

Why Osteoporosis Often Goes Undetected

Osteoporosis is often called a "silent disease" because it usually causes no symptoms until a bone breaks. Many people only discover they have osteoporosis after experiencing a fracture. The most common fracture sites include the:

  • Hip
  • Wrist
  • Spine

Why Osteoporosis Is More Common In Women

According to the US Centers for Disease Control and Prevention (CDC), data from 2017-2018, published in 2021, showed that:

  • 19.6 per cent of women aged 50 and older had osteoporosis in the femur or lower spine.
  • In comparison, 4.4 per cent of men had osteoporosis.

The study also found that osteopenia—a condition of lower-than-normal bone density that often precedes osteoporosis—was more common in women than men. While osteopenia affected 51.5 per cent of women, it affected 33.5 per cent of men.

In women, osteoporosis is commonly linked to the hormonal changes that occur after menopause.

Estrogen plays an essential role in building and maintaining strong bones. After menopause, estrogen levels decline significantly, accelerating bone loss and increasing the risk of osteoporosis.

People who do not build strong bones during childhood and early adulthood are also at greater risk later in life. Factors such as lack of physical activity, eating disorders, and certain health conditions can prevent the body from achieving optimal bone mass during the younger years.

What Is Osteoporosis Screening?

Doctors use imaging tests to measure bone density and diagnose osteoporosis. A DXA (dual-energy X-ray absorptiometry) scan is the standard diagnostic test and measures bone density in the spine, hip, and wrist using a very small amount of radiation.

Ultrasound can also assess bone quality, but it is not used alone to diagnose osteoporosis. If ultrasound findings suggest bone loss, a DXA scan is still required to confirm the diagnosis.

Is Osteoporosis Treatable?

There is currently no cure for osteoporosis, but treatment and lifestyle changes can help slow bone loss and reduce the risk of fractures.

Experts recommend:

  • Stay physically active and do weight-bearing exercises such as walking.
  • Do not smoke.
  • Limit alcohol consumption.
  • Get enough calcium and vitamin D through your diet. Your healthcare provider may also recommend calcium and vitamin D supplements if needed

Cosmeticorexia: The Dark Side Of Teenagers' Obsession With Flawless Skin

Updated Jul 12, 2026 | 11:00 PM IST

SummaryCosmeticorexia is a growing trend in which teenagers become excessively obsessed with achieving "perfect" skin, often leading to compulsive skincare routines, emotional distress, and unrealistic beauty expectations fueled by social media.

Thanks to growing popularity of complex and elaborate skincare trends on social media, perfect skin has become the ultimate beauty goal for many teenagers.

But experts are warning that this obsession is fueling a worrying condition known as cosmeticorexia, where young people use anti-aging and active skincare products far beyond what their skin needs, increasing the risk of irritation, allergies, and long-term damage.

When Skincare Turns Into Skin Damage

Teenagers and even younger children suffer from severe skin damage, chemical burns, and dermatitis. The cause of this issue is not a common medical condition but a reflection of an unhealthy trend called cosmeticorexia (dermorexia).

This dangerous obsession pushes people to treat their skin as an unacceptable defect that needs to be constantly adjusted, filed, tightened, peeled, and made younger.

Social media and anti-aging marketing culture promote this disorder by encouraging adolescents to use various comedogenic creams, serums, and toners with harmful effects on sensitive and fragile skin. Thus, millions of teenagers damage their skin beyond repair before it naturally matures.

Why Teen Skin Is More Vulnerable

There are multiple concerns about the health of teenage skin from a medical perspective. The skin of adolescents is thinner and more sensitive to external influences.

In addition, teenagers' skin is subject to increased sebum production and associated risks of comedones, blackheads, and dermatitis.

The Hidden Risks Of Trendy Skincare Products

The use of "cosmeceuticals" or prescription drugs with neurotoxins, retinol, AHA (glycolic acid), and vitamin C can accelerate skin damage when used inappropriately.

Recent research has shown that the standard skincare regimen of a teenager who follows social media and beauty vloggers includes more than eleven irritating substances. Topical application of such a combination of cosmetics damages the upper layer of the skin, provoking allergic reactions, dermatitis, redness, and irritation.

Moreover, the use of retinol and AHA (glycolic acid) without medical supervision may lead to photosensitivity, increasing the risk of UV-induced skin damage. Finally, an increasing number of cases of allergic contact dermatitis are linked to synthetic and harmful substances found in luxury cosmetic products.

Cosmeticorexia: A Psychological And Skin Health Disorder

Cosmeticorexia is an example of a psychodermatological disease, where psychological problems manifest through dermatological conditions.

The constant pursuit of flawless skin can lead adolescents to adopt harmful skincare practices that ultimately damage their skin rather than improve it.

The Right Skincare Routine For Teenagers

From a medical point of view, the role of healthcare providers is to combat this dangerous trend by addressing its immediate consequences.

Teenagers' skin does not require anti-aging treatments or additional nourishment. The only essential skincare routine includes three simple steps: gentle cleansing, applying a non-comedogenic moisturizer, and using a hydrating sunscreen every day.

Protecting Teens From Harmful Beauty Trends

Doctors, parents, educators, and social media platforms must work together to counter the anti-aging industry's growing influence on teenagers.

Raising awareness about age-appropriate skincare and discouraging unnecessary cosmetic treatments can help protect young people from avoidable chemical damage and long-term skin problems.

World Population Day: How America's Falling Birth Rate Is Redefining Women's Healthcare?

Updated Jul 12, 2026 | 09:06 AM IST

SummaryOn World Population Day, we look behind the rapidly changing women's healthcare landscape in the United States, driven by a lower birth rate.
World Population Day: Why America's Falling Birth Rate Is Redefining Women's Healthcare?

America's falling birth rate is often reported with concerns like shortage of labour, a growing aging population, and slower population growth. But another major consequence is unfolding within the healthcare system that is going unnoticed.

As fewer women have children and more delay pregnancy, women's healthcare is evolving beyond maternity care to address changing health needs.

The U.S. Birth Rate Is Declining

According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), 3.63 million babies were born in the United States in 2024, a slight increase from 2023.

However, the general fertility rate fell to a record-low 53.8 births per 1,000 women aged 15 to 44, marking the lowest level ever recorded.

Women’s Healthcare Is Evolving In The US

One of the biggest changes is maternity care. With fewer births being reported, hospitals, particularly in rural communities, are struggling to keep labour and delivery departments financially viable.

The problem has contributed to the rise of a maternity care challenge where pregnant women have limited or no access to obstetric services.

The 2024 March of Dimes Maternity Care Deserts Report found that more than one in three U.S. counties lack a single obstetric clinician or birthing facility, leaving millions of women with reduced access to prenatal and delivery care.

Women living in these areas are more likely to receive inadequate prenatal care and experience higher rates of preterm birth.

Healthcare Focus Beyond Pregnancy

At the same time, healthcare providers are broadening their focus beyond pregnancy. Women today are delaying childbirth, having fewer children, or choosing not to become parents altogether.

As life expectancy increases, demand is growing for services related to menopause, cardiovascular disease, osteoporosis, pelvic floor disorders, mental health, and healthy aging.

The shift also explains why fertility care is expanding despite declining birth rates. As more Americans postpone parenthood into their late 30s and 40s, many require fertility evaluations, egg freezing, or in vitro fertilization (IVF).

Rather than indicating more births, the growing use of assisted reproductive technology reflects changing reproductive timelines.

Management Of Chronic Lifestyle Disorders

An aging female population is also changing healthcare priorities. Older women face a higher risk of chronic diseases such as heart disease, diabetes, osteoporosis, and dementia, increasing the need for preventive care and long-term disease management.

Health systems are investing more in menopause clinics, wellness programs, and other women's health services.

America's falling birth rate is therefore reshaping far more than population statistics. It is redefining women's healthcare, shifting the focus from pregnancy-related care to comprehensive support throughout every stage of life.

On World Population Day, the conversation is not just about how many babies are being born. It is also about ensuring that healthcare evolves to meet the changing needs of women, whether or not they choose to become mothers.
