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.

People think of menopause as just hot flashes and irregular periods, but menopause is more than that.
Perimenopause and menopause can bring a host of emotional and cognitive shifts for many women, including mood swings, anxiety, easily irritated, trouble sleeping, or having what some refer to as “brain fog.”
Perimenopause is the period leading up to menopause that can last anywhere from two to eight years. This is when hormonal changes take place, especially a drop in estrogen.
These hormonal changes also impact neurotransmitters like serotonin and dopamine that are essential for mood, memory, sleep and emotional wellness.
Consequently, a woman can suffer from forgetfulness, lack of concentration, mental tiredness, low energy levels, dry skin, loss of libido and less productivity.

Brain fog can be a frustrating and overwhelming experience during menopause, particularly if a woman is juggling her career, family, ageing parents and personal obligations.
Many women suffer from anxiety symptoms, even if they have no mental health background. Hormonal changes, poor sleep and stress can exacerbate these symptoms.
But not all symptoms are due to the menopause or "normal ageing". Thyroid disorders, vitamin deficiencies, depression and other medical problems can have similar symptoms.
Therefore, if symptoms start to impact life, work, relationships or emotional wellbeing, it is important to seek medical advice and have a proper health check-up.
Management is often comprehensive, and may involve lifestyle modifications. Regular exercise, balanced nutrition, stress management and healthy sleep patterns.
In a few instances, you may additionally be suggested to take Menopausal Hormone Therapy (MHT). As more research is done and preparations of lower doses and greater safety, earlier misconceptions about hormone therapy are gradually decreasing.
Medically, women can make a difference in their quality of lives and manage menopause with greater physical, mental and emotional wellness with early recognition and timely intervention.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.
Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.
Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.
Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.
Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.
This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.
Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.
Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.
All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.
Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.
Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.
Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.

We tend to think of our eyes as easy – they just "see", and we go about our day. But the fact is, your eyes are adapting a lot, focusing and straining all the time, far more than you realize. Many of these moments are utterly unremarkable, but they build up gradually into a tiredness, a dryness and a long-term strain.
We see many people who are shocked to find out how hard their eyes had been working long before any symptoms appeared. Here are six common situations that deserve a whole lot more attention – and care – from your eyes.
Having a quick glance at notifications before even leaving bed requires your eyes to adjust to a small, bright screen in the dark. This quick change puts a load on the eye muscles and can make them tire before your day has really started.
Working, studying, and hopping from meeting to meeting: extended hours in front of the screen drastically lower your usual blink rate. Less blinking equals less lubrication, which is why so many people are dry, irritated and have blurry vision by the afternoon.
Night driving is one of the most challenging visual jobs humans undertake, given low light, incoming headlights and the need to constantly change focus between the road, mirrors and dashboard. Your eyes are working tirelessly to shift between bright and dim situations in fractions of a second.

Poorly lit restaurant menus, pharmaceutical labels, or the small text on a contract all demand that you focus hard at close range, frequently in less-than-ideal illumination. As we get older, this type of near-focus strain is very common since our natural ability to focus declines.
Glancing from your laptop to your phone to a television and back again, it makes your eyes refocus at multiple distances. It is easier, but this continual flipping is more tiring than looking at one screen for the same period of time.
Your eyes work hard to adjust while you move from a dim room into harsh daylight — or vice versa. Over time, repeated exposure to glare without the correct protection (such as sunglasses) can add unneeded strain.
None of these moments feel dramatic on their own, but together, they represent a significant daily workload for your eyes. The good news is that habits such as the 20-20-20 rule, correct lighting, regular blinking and eye check-ups can go a long way in reducing this concealed tension. We believe that awareness is the beginning of healthy eyesight.
If you are suffering frequent eye strain, dryness or fuzzy vision, it may be time to schedule a full eye exam. Your eyes work harder than you realize – let’s give them the attention they deserve.
