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.

Dehydration is a serious concern for people fasting during the month-long Ramadan period, and can severely impact kidney and prostate health. Experts suggested that avoiding excess salt and caffeine can help.

While Ramadan fasting is generally safe for people with early-stage chronic kidney disease (CKD), maintaining adequate hydration between iftar and sehri -- the two important meals each day for faithful observing the fasting -- is of significant importance.

Dehydration can lead to acute kidney injury and electrolyte imbalances for individuals with advanced CKD. As prolonged fasting hours -- more than 12 hours a day -- urine becomes concentrated, increasing the risk for kidney stones and Urinary Tract infections (UTIs).

For men with prostate problems, fasting during Ramadan can pose challenges, such as Benign Prostatic Hyperplasia (BPH) or an enlarged prostate, primarily due to dehydration.

“As a practicing urologist and kidney transplant surgeon in India, I often notice a rise in kidney stone pain and urinary infections during Ramzan. When patients fast for long hours -- especially in our warm climate -- urine becomes highly concentrated. That increases the risk of stones and UTIs. Men with prostate enlargement sometimes report worsening urinary flow because they consciously reduce fluid intake,” Dr. Pankaj Panwar, Additional Director, Urology, Fortis Escorts Okhla, New Delhi, told HealthandMe.

The doctor advised people “to hydrate strategically between Iftar and Sehri, avoid excess salt and caffeine”.

How Excess Salt And Caffeine Impact Ramadan Fasting

Consuming high-sodium foods such as processed meats, pickles, salty snacks, and fast food during iftar or sehri can increase thirst and dehydration.

High salt intake forces the body to pull water from cells to dilute the sodium, leading to severe thirst. It can also lead to bloating.

Similarly, caffeine in coffee, tea, chocolate, and energy drinks can be diuretic and cause the body to lose fluids and salts through increased urination. Particularly, drinking coffee or tea at sehri -- the pre-dawn meal -- can lead to faster dehydration during the day.

Caffeine consumption, especially late in the evening, can also interfere with sleep, making it harder to wake up for sehri.

“Ramzan is a sacred month of fasting, but prolonged abstinence from water, especially in hot climates, can increase dehydration risk. Concentrated urine puts stress on the kidneys and may worsen kidney stones or trigger urinary tract infections,” Dr. Mangesh Patil, Urologist at Saifee Hospital, Mumbai, told HealthandMe.

Dehydration during Ramadan fasting can lead to symptoms like headaches, extreme thirst, fatigue, and dizziness. But in case of severe dizziness, fever, confusion, or blurred vision, the experts warned of immediate medical help.

“Do not ignore warning signs like flank pain, fever, or difficulty passing urine. A little planning can prevent an emergency hospital visit,” Panwar said.

Patil said warning signs include severe flank pain, burning urination, fever, vomiting, blood in urine, or reduced urine output. Men with Benign Prostatic Hyperplasia may notice worsening urinary symptoms.

Tips To Prevent Complications

• Drink 2-3 liters of water between iftar and sehri
• Include water-rich fruits
• Avoid excess salt and caffeine
• Individuals with kidney disease, stones, UTIs, or prostate issues should consult their doctor before fasting.

Ever wondered how your body generates antibodies in the face of a virus attack? A new study by French researchers showed that our age, biological sex, and human genetic factors can determine our immunity levels.

The human body, when exposed to a virus, defends itself by producing molecules called antibodies. Their main function is to identify pathogens and kill them.

Scientists from the Institut Pasteur, the CNRS, and the Collège de France noted that these factors not only boost the quantity of antibodies produced in the body but also determine the specific viral regions to target.

The February 2026 study, published in the journal Nature Immunology, can pave the way for the development of personalized treatments, especially for individuals who are most vulnerable to infection.

"This study provides a detailed, integrated view of how age, sex, and human genetics shape the antibody response," said Lluis Quintana-Murci, Head of the Human Evolutionary Genetics laboratory at the Institut Pasteur.

"It shows that these factors even determine which specific regions of a given virus are targeted by antibodies, with important implications for vaccine and therapeutic design," Quintana-Murci added.

How Age And Sex Influence Immunity

The findings revealed that individuals produce antibodies that target different parts of the virus when attacked by the same virus. Age was identified as the dominant factor influencing antibody production. The team noted that more than half of the antibody repertoire varies depending on age.

Further, some antibodies were found to increase with age, while others decreased. This was seen particularly in the case of influenza H1N1 and H3N2 viruses.

In young adults, the antibodies mainly targeted a part of the viral surface protein known as hemagglutinin (HA), which evolves rapidly. In older individuals, it focused on a more stable region of the same protein known as the stalk domain.

Women were also found to produce more antibodies against HA. On the other hand, men tended to target other viral proteins (NP and M1), despite comparable vaccination rates between the two sexes.

How Human Genetics Shape Antibody Production

The team identified mutations in genomic regions known to encode the immunoglobulin repertoire. These variants determine which genes are used to produce antibodies.

Using an African cohort, the study revealed population disparities in terms of the molecular targets of their antibody repertoires.

In the case of Epstein-Barr virus (EBV), antibodies were found to recognize different viral proteins depending on the geographical and epidemiological context.

This difference can be explained by the level of exposure -- Africans are more exposed to a particular strain of EBV in which the protein EBNA-4 is the primary antibody target.

How Was The Study Conducted?

The research is based on data from the Milieu Intérieur cohort, launched 15 years ago to study variations in the immune response in 1,000 healthy individuals.

Using an innovative sequencing technology, the scientists analyzed blood plasma samples to measure antibody responses against more than 90,000 fragments of viral proteins, covering a large number of viruses responsible for infections such as influenza, respiratory infections, gastroenteritis, and herpesvirus infections.

Epstein Files: After the Department of Justice (DOJ) released more files on the late sex offender and financer Jeffrey Epstein, previously unseen photographs, including medical details and a detailed timeline of his final weeks in custody have resurfaced. All of this new information has added fresh scrutiny to the case.

A 23-page long document, labelled unclassified titled Jefferey Epstein Death Investigation was prepared by the New York field officer of the FBI. The material has been examined by BBC Verify and was reported to contain close-up images of Epstein's body, notes from his post-mortem examination and psychological observations that were recorded shortly before his death in August 2019.

As per BBC, the photographs included detailed views of injuries to Epstein's neck and show medics attempting to resuscitation after he was found unresponsive in his jail cell. As per the timestamps visible in the files, the images were taken at 06:40 local time on 10 August 2019, almost 16 minutes after a prison staff discovered him.

As per the DOJ's Office of the Inspector General's review report released in June 2023, on August 10 at 6.30am, two SHU staff on duty CO Tova Noel and Material Handler Michael Thomas delivered breakfast to inmates, when Noel was delivering breakfast from the food slot of the door to Epstein's SHU tier, there was no response. Thomas unlocked the door and saw Epstein hanged. The review report mentions that he immediately "yelled for Noel to get help and call for a medical emergency". According to Noel, within seconds of Thomas calling out for the clutter she hit the body alarm, which is a button on an MCC staff member's radio that is used to signal distress or an emergency. Noel also recalled Thomas saying, "Breathe, Epstein, breathe." As per Noel, when she saw Epstein, he looked "blue and did not have a shirt or anything around his neck".

As per Thomas, when he entered Epstein's cell, he had an orange string, from a sheet or a shirt, around his neck that was tied t the top portion of the bunkbed. The review report notes: "Epstein was suspended from the top bunk in a near-seated position, with his buttocks approximately 1 inch to 1 inch and a half off the floor." As per Thomas, he immediately ripped the orange string from the bunkbed and Epstein's buttocks dropped to the ground, and lowered him to begin chest compressions until staff arrived.

As per the BBC reports, the location is not explicitly stated in the documents, but records indicate Epstein had already been transported to hospital at 06:39, where he was later pronounced dead, suggesting the images were likely taken there.

Some of the photographs show a tag attached to his hand with his name and date of death. In several images, however, his first name appears misspelled as “Jeffery”.

The investigation file incorporates sections of an 89-page post-mortem report compiled jointly by the Department of Justice and New York’s Office of Chief Medical Examiner. Among the medical findings were scans documenting fractures in the thyroid cartilage of Epstein’s neck.

BBC Verify said it conducted reverse image searches and “could not find earlier versions” of the photos online before their recent release, indicating they had not previously circulated publicly.

The report also reconstructs Epstein’s detention inside the Metropolitan Correctional Center from his arrest on 6 July 2019 on federal sex-trafficking charges to his death five weeks later.

According to the timeline, Epstein was placed on suicide watch after a 23 July incident in which he was found injured in his cell. At the time, he claimed his cellmate — Nicholas Tartaglione — had attacked him.

Epstein Files: Jeffrey Epstein's Psychological Assessment Before His Death

The following day, during a psychological assessment, Epstein denied wanting to harm himself. BBC reported the document states he said he had “no interest in killing myself” and that it “would be crazy” to do so. Two days later, notes record him saying he was “too vested in my case” and wanted to return to his life.

Despite that, prison officials had recommended he not be housed alone and that guards perform checks every 30 minutes, including unannounced rounds.

The newly released records outline several security lapses the night before Epstein died.

His cellmate had been transferred out the previous day, leaving him alone. Prison logs show guards failed to conduct scheduled checks at 03:00 and 05:00, and the unit’s camera system was not functioning. Staff later discovered his body during a morning inspection.

The files also include two versions of the same FBI report: a full 23-page unredacted copy and a shorter 17-page redacted version that omits the psychological report and detention timeline. The reason for the dual publication has not been explained.

The Department of Justice has been contacted for comment, while the FBI declined to respond, reported BBC.

The release of the material does not change the official ruling of suicide, but its level of detail, particularly the photographs, mental-health notes and security failures — is likely to reignite debate over the circumstances surrounding Epstein’s death.
