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.

Can Your Voice Predict Future Chronic Disease Risk?

Updated Feb 8, 2026 | 04:58 PM IST

SummaryYour voice is produced by the coordinated effort of your respiratory system, vocal cords (also called vocal folds), and the resonating chambers of your throat, mouth, and nose. Even subtle shifts in hormone levels, hydration status or tissue health can noticeably affect how you sound.

Changes in your voice, whether in tone, volume, speed or overall quality, can act as early warning signs for a wide range of medical conditions, experts say.

Your voice is produced by the coordinated effort of your respiratory system, vocal cords (also called vocal folds), and the resonating chambers of your throat, mouth, and nose. Even subtle shifts in hormone levels, hydration status or tissue health can noticeably affect how you sound.

Recent research shows that subtle changes in speech, for example, slurring or vocal cord tremors, may be signs of disease or illness like Parkinson’s disease, depression, cardiac and mental health problems, as speech requires coordination with the brain, muscles and respiratory system.

Which Conditions Can You Identify By A Change In Voice?

  • Diabetes: High-pitched, raspy voices or vocal strain can be linked to diabetes, with AI studies showing up to 75% accuracy in prediction.
  • Cardiovascular Disease: Voice analysis can detect high, fluttering voices associated with coronary artery disease, caused by stress or fluid changes in the vocal cords.
  • Hypothyroidism: A deeper, softer, or huskier voice can indicate thyroid dysfunction.
  • Respiratory Illnesses: Conditions like COVID-19 or COPD are often associated with a breathy voice, coughing, and short, interrupted sentences.
  • Throat Cancer: Persistent hoarseness and raspy voice, especially lasting more than 2-3 weeks, can indicate laryngeal cancer.
  • Parkinson’s Disease: Identified by a monotone voice, reduced volume, increased breathiness, and vocal cord tremors.
  • Alzheimer’s Disease/Dementia: Characterized by slower speech rates, hesitation, frequent pauses, and simplified vocabulary/sentence structure.
  • Stroke or Brain Injury: Indicated by slurred speech or difficulty finding words (global aphasia).
  • Cerebellar Disorders (caused by damage to the nerves in the brain's cerebellum): Manifest as loud, staccato speech (bursts of broken sounds).
  • Depression: Linked to a flatter, softer, and more monotone voice with a reduced pitch range.
  • Anxiety/Stress: Often presents as a higher-pitched, faster, and more tremulous voice.
  • Schizophrenia: Indicated by monotone, disorganized speech.

What Else Can Affect Your Voice?

Apart from serious medical conditions, voice changes may also be linked to aging and lifestyle factors. Fluctuations in testosterone, estrogen, progesterone, and thyroid hormone levels may also influence the structure and function of the vocal cords.

Dehydration is one of the most common causes of voice problems, as cords need adequate moisture to vibrate efficiently. Aim for at least 64 ounces of water daily, and more if you use your voice professionally or live in a dry climate.

Smoking irritates and inflames the vocal cords, causing chronic hoarseness and increasing the risk of vocal cord cancer. Even secondhand smoke and vaping can affect voice quality.

Diet also plays a role in vocal health. Caffeine and alcohol are diuretics that can dehydrate your vocal cords. Spicy foods and acidic beverages may trigger reflux, irritating the throat.

Dairy products can increase mucus production in some people, affecting voice clarity. Voice overuse or misuse, common in teachers, singers, and public speakers, can lead to vocal fatigue and damage. The following table compares how different lifestyle factors impact your voice.

How Can You Take Care Of Your Voice?

Whether the cause is hormonal changes, medical conditions, aging, or lifestyle factors, most voice problems can be improved with proper diagnosis and treatment. Here are some things you can do to take care:

  • Stay hydrated by drinking water throughout the day and using a humidifier in dry environments
  • Warm up your voice before extended speaking or singing with gentle humming or lip trills
  • Avoid shouting or whispering, both of which strain the vocal cords
  • Take voice breaks during prolonged speaking to prevent fatigue
  • Manage stress through relaxation techniques, as tension affects voice quality
  • Treat allergies and sinus problems promptly to reduce postnasal drip
  • Maintain good posture to support optimal breathing and voice production

Feeling Lonely Or Judged Raises Risk of Dementia, Study Suggests

Updated Feb 8, 2026 | 12:29 PM IST

SummaryPsychosocial stress is a type of stress related to our relationships with others, usually arising from feeling judged, excluded, or not enough in others' eyes. This form of stress can trigger physiological responses like increased heart rate, cortisol secretion, and inflammation, significantly increasing risks for hypertension, cardiovascular disease and mental health disorders

Living under constant psychosocial stress can significantly raise the risk of developing dementia and a stroke, a JAMA Network study suggests.

Psychosocial stress is a type of stress related to our relationships with others, usually arising from feeling judged, excluded, or not enough in others' eyes. It can also put a person in fight-or-flight mode, causing both mental and physical symptoms.

According to Chinese researchers, people who experience this form of stress in childhood as well as adulthood face more than a threefold higher risk of developing dementia compared with those in other groups.

Similarly, young people experiencing stressful situations in their adulthood had a significantly higher risk of stroke incidence that their counterparts.

Based on these results, the study highlights that early identification of psychosocial stressors, combined with effective mental health support and depression prevention, may reduce the long-term burden of neurodegenerative and cerebrovascular disease.

What Did The Study Find?

In this population-based cohort study of more than 11,600 middle-aged and older adults, nearly four in five participants reported at least one adverse childhood experience, while over one-third experienced adversity during adulthood.

The scientists defined adverse childhood experiences (ACEs) as traumatic exposures occurring during childhood, typically grouped into 3 categories: household dysfunction, social dysfunction and family death or disability.

On the other hand, traumatic exposures occurring during adulthood were defined as adverse adult experiences (AAEs), which include events such as the death of a child, lifetime discrimination, ever being confined to bed, ever being hospitalized for a month or longer and ever leaving a job due to health conditions.

While analyzing the data they collected from the participants, the researchers also found that depression partly explained the links in all major relationships as it accounted for more than one-third of the connection between childhood adversity and dementia, and about one-fifth of the link between adulthood adversity and both dementia and stroke.

These findings suggest that long-term psychological stress may lead to brain and blood vessel diseases by causing ongoing emotional distress, unhealthy behaviours, and biological changes like inflammation and abnormal stress responses.

Psychosocial Stress: An Unseen Form Of Stress

Psychosocial stress can trigger physiological responses like increased heart rate, cortisol secretion, and inflammation, significantly increasing risks for hypertension, cardiovascular disease and mental health disorders.

This kind of stress can affect men, women, and people of all genders differently, but many of the symptoms are still the same. Common symptoms include:

  • Sweating
  • An increase in blood pressure
  • Rapid heartbeat
  • Dizziness
  • Nausea and digestive problems
  • Strong emotional reactions such as sadness or irritability
  • Drug or alcohol abuse

These symptoms can be acute or chronic, meaning for some people they go away, and for others, they persist over a long period of time. Meeting with a therapist is often recommended for those living with chronic stress.

Experts typically suggest developing coping mechanisms include building support networks, utilizing relaxation techniques, and, in cases of severe mental impact, seeking professional support to help deal with psychosocial stress.

Why Are US Women Dressed In Red?

Updated Feb 8, 2026 | 05:56 AM IST

SummaryHeart disease remains the top killer of women, yet is often overlooked. During American Heart Month, women across Ohio wear red to spotlight risks, drive awareness, fund research, promote early detection, and urge year-round heart health action through community campaigns today.

Cardiovascular disease remains the leading cause of death among women, claiming more lives each year than all cancers combined. Yet, it continues to be misunderstood, underdiagnosed, and often dismissed as a “male” health problem. In Ohio and across the US, women are now using a striking visual message to confront this reality head-on, by quite literally dressing for the cause.

February, observed as American Heart Month, marks a renewed push to educate communities about heart disease, especially among women. Health advocates stress that while the spotlight is brightest this month, the risks and responsibilities extend far beyond the calendar.

“It’s our Super Bowl,” said Lauren Thomas, development director for the American Heart Association of North Central West Virginia and Ohio Valley. “It’s about awareness. Heart health is not a one-month conversation. It has to be a year-round priority where people actively put their hearts first.”

Why Red Has Become a Warning Sign

Across Ohio, women are wearing red, a color long associated with love but also with danger. The message is deliberate. Red symbolizes the urgency of cardiovascular disease, a condition responsible for one in every three deaths among women.

“When we wear red, we start conversations that many people avoid,” said Melissa Pratt, a heart disease survivor, reported WBBJ News. “One in three women die from cardiovascular disease. Wearing red encourages women to get checked, understand their risks, and take their health seriously.”

From landmarks lit in red to workplaces, neighborhoods, and social media feeds filled with crimson outfits, the visual campaign is meant to disrupt complacency. It asks a confronting question. If heart disease is killing women at this scale, why is it still not treated like a crisis?

Ohio Valley And Downtown Jackson Women Taking the Lead

Coinciding with American Heart Month, the Ohio Valley Women of Impact campaign launches this Friday. Six local women, Crissy Clutter, Jan Pattishall-Krupinski, Lacy Ferguson, Shelbie Smith, Jennifer Hall-Fawson, and Laurie Conway, are leading fundraising and awareness efforts aimed at improving women’s heart health.

Their work focuses on education, early detection, and supporting research that better understands how heart disease presents differently in women. Symptoms in women can be subtle, ranging from fatigue and nausea to jaw or back pain, which often delays diagnosis and treatment.

Turning Awareness Into Action

To mark the start of the month, the American Heart Association hosted a National Wear Red Day breakfast on Friday morning at the LIFT Wellness Center in Jackson Walk Plaza. The event brought together survivors, advocates, and health professionals to reinforce a simple but powerful message. Awareness must lead to action.

Health experts continue to urge women to prioritize regular checkups, manage blood pressure, cholesterol, and stress, and recognize early warning signs. Lifestyle changes, timely screenings, and informed conversations can significantly reduce risk.

Dressed In Death, Fighting For Life

The women of Ohio are not wearing red for fashion. They are wearing it as a warning, a remembrance, and a call to action. In dressing themselves in the color of urgency, they are confronting a disease that has taken too many lives quietly. This February, their message is clear. Heart disease is not inevitable, but ignoring it can be deadly.
