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.
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.
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.
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:
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.
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.
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.
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.
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.

The NHS has shared important guidance on its website for anyone prescribed lansoprazole, especially those taking it for three months or longer. The health service’s site provides trusted, evidence-based advice on many medications and health conditions, helping patients make informed decisions about their treatment.
Lansoprazole is a commonly prescribed medicine in the UK, belonging to a group called proton pump inhibitors (PPIs). PPIs make up a large portion of prescriptions dispensed in England. Lansoprazole works by reducing the amount of acid in the stomach and is used to treat and prevent various acid-related conditions, as per NHS.
There are four other PPIs similar to lansoprazole: omeprazole, esomeprazole, pantoprazole, and rabeprazole. These medicines lower stomach acid in the same way and generally have similar effects and side effects. Doctors may prescribe a different PPI if lansoprazole is not working as expected or if side effects occur.
People taking lansoprazole often notice improvements in two to three days, though it may take up to four weeks for full effect, so some symptoms can continue during this period.
The duration of lansoprazole treatment depends on the condition being treated. It is usually advised to take the lowest effective dose for the shortest period to prevent long-term side effects. Some people take lansoprazole for extended periods, sometimes even years, but it should always be under regular supervision by a doctor because of potential risks.
The NHS notes that taking lansoprazole for more than three months can reduce magnesium levels in the blood. Low magnesium may cause fatigue, confusion, dizziness, muscle twitches, shakiness, and irregular heartbeats. Anyone experiencing these symptoms should consult their doctor.
Magnesium is vital for over 300 functions in the body, including nerve and muscle activity (including the heart), bone health, energy production, blood sugar regulation, and blood pressure control. Low magnesium can lead to muscle cramps, tiredness, irregular heart rhythms, and long-term problems like high blood pressure, type 2 diabetes, and weakened bones. It also affects cellular functions and the body’s electrolyte balance.
Using lansoprazole for more than a year may raise the risk of side effects such as bone fractures, gut infections, and vitamin B12 deficiency. Symptoms of B12 deficiency include extreme fatigue, a sore or red tongue, mouth ulcers, and pins-and-needles sensations. Anyone noticing these signs or taking lansoprazole for extended periods should schedule regular check-ups.
The NHS advises: “If you take lansoprazole for more than a year, your doctor will monitor your health to determine whether you should continue treatment. It is unclear if lansoprazole becomes less effective over time. If you feel it is no longer helping, speak to your doctor.”
Patients should inform their doctor of all other medications, vitamins, or supplements they are taking. Lansoprazole can interact with drugs like warfarin, digoxin, and certain HIV medications. Antacids such as Gaviscon should not be taken within two hours of lansoprazole. Herbal remedies like St John’s wort should also be avoided while on this medication.
Seek urgent medical attention or call emergency services if you experience severe symptoms, including allergic reactions (swelling of the face or throat, difficulty breathing), worsening stomach pain, severe or persistent diarrhoea, or signs of low magnesium, such as muscle spasms, irregular heartbeat, or confusion.
The NHS notes that there is some evidence suggesting a very small increased risk of stomach cancer for people taking acid-reducing medicines, including PPIs like lansoprazole and H2 blockers, especially for more than three years. However, larger studies are needed to confirm a direct link.
PPIs, like any medicine, can have side effects, so it is recommended to use them for the shortest effective period. Anyone noticing potential signs of stomach cancer—difficulty swallowing, vomiting, feeling full quickly, or unexplained weight loss—should speak to their doctor or pharmacist promptly.

This year, Nick Jonas has completed 20 years with type 1 diabetes. This is also the same year when his band, the Jonas Brothers have also hit the mark of 20th anniversary. Speaking to Healthline, Jonas said, "It is crazy hpw it lined up. It has been a wild journey in both... in the Brothers sense, it's been the ride of a lifetime, and we have been so fortunate to be able to do this for 20 years now and to have the support of the world's greatest fans."
He also revealed that he had great and some tough times too living with diabetes. There had been struggles of managing his low, however, he revealed that being the spokesperson of Dexcom, a healthcare company known for its glucose monitoring system, and through his own non-profit initiative Beyond Type 1, he has been joyful. “Overall, I’m really grateful to have been able to be transparent about [type 1] and to connect with all these wonderful people from all regions of the world who are experiencing their own diabetes journey, and it’s a really big thing to feel like you’re a little less alone in it,” said Jonas.
On World Diabetes Day, which was on November 14, Jonas took to the stage during a Jonas Brothers concert and shared the audience his A1C. This is a test that measures one's average blood sugar over the past 2 to 3 months. This number shows how well diabetes has been managed. He shared an inspiring message of hope, while giving a shoutout to his A1C. The concert was attended by Dexcom Warrior community, which makes more than 30,000 people who have been diagnosed with diabetes and may share the same experiences. “It was really special for me to get to use the Jonas Brothers’ platform as a place to speak about something that’s obviously very personal to me and on World Diabetes Day, I think it’s natural to get reflective and to tap into kind of what life looks like for me as a now 33-year-old person living with this disease,” he said.
He also dedicated the song 'A Little Bit Longer', that he had written very early on in his career during his diabetes journey. “It’s a really important time for me to get to speak on stage like that and play a song that I wrote about these experiences when I was 14 and to see the impact it still has to this day with the fan base,” he said.
Here are some strategies Jonas uses that helped him manage his diabetes. First off the list is to take the pressure off. “You’re never going to have the perfect day living with this disease and even if you’re super on top of your diabetes management, there are just things that are a little out of your control and being able to take a deep breath, reset, and know that it’s going to be OK on the other side is really important,” he said.
It may seem hard, but he said learning it in the beginning of his diagnosis helped him manage his diabetes. Then comes the care. He has focused on taking vitamins, caring for his skin, and most importantly, staying hydrated. “It’s a simple thing, but the more water I drink, my glucose levels are better. I don’t know exactly why, but I just find that hydrating has a lot of health benefits,” said Jonas. “I didn’t put as much focus on it earlier in my life as I do now, and it’s been really beneficial.”
Physical activity is a must. He walks for 30 minutes daily, or sometimes longer for his physical, mental, and emotional health. “It really centers me and even when it’s cold out, getting out in the fresh air is really important when a lot of my day too, is spent indoors for hours at venue or on a film set or something,” he said.
His focus on self, he says is the most important as he says he relies on his therapist from time to time. "I think it is really important to do that self-work". Lastly, he says everyone who has been diagnosed with diabetes, must take part in the community. “There will be good days, there will be tough days, but you can climb this mountain, and there’s some incredible people out there whose stories will really inspire anybody that’s going through tough moments,” said Jonas.

People prescribed venlafaxine are being urged to stay alert to certain symptoms and side effects that may require medical advice from NHS 111 or their GP. Venlafaxine is a widely used SNRI antidepressant. It is mainly prescribed for depression, but doctors may also recommend it for anxiety disorders and panic attacks.
Venlafaxine, sold under brand names such as Effexor and Effexor XR, is a prescription antidepressant classified as a serotonin-norepinephrine reuptake inhibitor. It helps regulate mood by raising levels of serotonin and norepinephrine in the brain, chemicals that play a key role in emotional balance and mental stability.
The medicine is usually taken as a tablet or capsule. It works by increasing levels of serotonin and noradrenaline in the brain, chemicals that help regulate mood. According to NHS guidance, venlafaxine tends to cause fewer side effects than older antidepressants. That said, it is not completely free of risks.
Most people begin to notice some improvement within one to two weeks, although it can take four to six weeks for the drug to have its full effect.
Common side effects listed by the NHS include sweating, nausea, a dry mouth, and headaches. These are generally mild and often ease as the body adjusts to the medication.
However, there are other, more serious side effects that may need prompt medical advice. While these reactions are uncommon and affect fewer than one in 100 people, the NHS advises contacting 111 or a GP if they occur.
NHS advice says you should speak to your GP if you notice unexpected weight gain or weight loss, or sudden changes to your menstrual cycle. This may include spotting, bleeding between periods, or unusually heavy periods.
Patients are also advised to contact their doctor or NHS 111 without delay if they experience any of the following symptoms while taking venlafaxine:
