Talking to TOI , he speaks about the evolving understanding of Alzheimer's and the way ahead. Excerpts:
You say that Alzheimer's is reversible. Could you explain how?
When I began my journey as a scientist decades ago, even during my time at Harvard, the consensus was that Alzheimer's could only be definitively diagnosed post-mortem and that there was virtually no hope for reversal. But today, we stand on a very different frontier. Our evolving understanding, supported by multi-omics, neurobiology, and functional medicine, tells us that Alzheimer's is not a singular condition with a singular cause. It is a syndrome with 100 different potential root causes, ranging from chronic inflammation and vascular compromise to environmental toxins, metabolic dysfunction, and infections. Once you accept that, the strategy shifts from 'waiting for a cure' to actively identifying and reversing the drivers in each patient.
Could you break down what makes Alzheimer's distinct from dementia?
Dementia is a broad term. It simply means that the brain isn't working the way it used to whether it's memory, decision-making, emotional processing, or cognition. Alzheimer's is a specific disease, the most common form of dementia, responsible for about 70% of cases in older adults. But not all dementia is Alzheimer's. Trauma, tumours, vascular issues, or infections can lead to dementia-like symptoms that are reversible if the underlying cause is treated.
You say that Alzheimer's begins decades before symptoms appear. Can you elaborate?
That's one of the most important insights. Alzheimer's pathology starts 20-30 years before the first symptom. The brain begins accumulating damage, amyloid plaques, tau tangles, inflammation, vascular compromise all silently. That's why early intervention is key. The earlier we can detect cognitive shifts and investigate root causes, the better our chances of slowing, halting, or even reversing the condition.
You mentioned hundreds of causes. Isn't that overwhelming?
It can be, but it also means there are many opportunities to intervene. One-size-fits-all medicine won't work. Instead, we assess each patient's environment, genetics, exposures, metabolic state, infections, and more. We've seen success using lifestyle-based protocols optimizing sleep, detoxification, nutrition, and exercise. For example, deep sleep (N3 stage) is critical. Every 1% reduction in N3 sleep increases Alzheimer's risk by 22%. Yet, most in the age group of 65-80 only get 15-30 minutes of N3 sleep. That's modifiable.
Are there examples of patients you've treated using this approach?
There are studies, patients reverse cognitive decline using protocols including Lion's Mane mushroom, Rosemary essential oil, detoxification, targeted anti-inflammatory therapies, and in some cases, cutting-edge interventions like Galectin-3 antibody therapy, which is showing remarkable promise without the side effects seen in amyloid-targeting drugs.
Can Covid-19 or its vaccine exacerbate or even trigger neurodegeneration?
We're seeing clear signals that both Covid-19 and spike proteins from vaccines may accelerate neuroinflammation in predisposed individuals, particularly those with high toxic burdens, poor sleep, chronic infections, or autoimmunity. But it's important to remember this is a layered phenomenon. Covid didn't create Alzheimer's, but it may tip the balance in vulnerable individuals. One UK post-mortem study even showed 5-10% brain mass shrinkage in individuals who had only mild Covid.
What role does lifestyle play in Alzheimer's prevention?
Alzheimer's doesn't start in the brain; it starts in the body. The way we live, our sleep patterns, food, activity levels, toxic exposures all influence cognitive longevity. Exercise increases BDNF, a growth factor that stimulates new neuron and synapse formation. Sauna therapy promotes detoxification and triggers heat shock proteins that may regenerate neural tissue. Diets high in processed sugar, salt, and seed oils are inflammatory and vascularly destructive, both are enemies of the brain.
You say Alzheimer's not as a tragedy but as a call to action. What's your message?

Baba Vanga's "Alien" Prediction For 2025: Here's Why Some Believe It's Coming True
Baba Vanga, a late Bulgarian clairvoyant who passed away over a quarter of a century ago, remains an active trend on social media because of her predictions. Her name was trending recently due to an alien-linked prediction she made for the year 2025. Baba Vanga has made a series of ominous predictions for 2025, most of which somehow end up in some kind of mass destruction and deaths. The mystic predicted that "aliens" would visit Earth in 2025. The prediction has created a buzz on social media, and some users believe that the prophecy is coming true with the discovery of a mysterious object, 3I/ATLAS, which is hurtling towards Earth. As per reports, Vanga warned: "Humanity will make contact with extraterrestrial life, possibly leading to a global crisis or apocalypse." The mysterious object, 3I/ATLAS, is reportedly moving at 1.3 lakh miles per hour. It is estimated to be 10-20 kilometres in size, roughly the size of a large city like Manhattan. Scientists detected 3I/ATLAS using a telescope in Chile, and its speed and trajectory have sparked interest in its origins and potential threat to Earth. Is It An Alien Spacecraft? Some scientists, including Harvard's Professor Avi Loeb, have claimed that 3I/ATLAS could be an alien spacecraft due to its unusual characteristics. Meanwhile, others say that it might be an asteroid or comet. NASA said that comet 3I/ATLAS is the third known object from outside our solar system to be discovered. The object has been categorised by astronomers as interstellar because of the hyperbolic shape of its orbital path. It does not follow a closed orbital path about the Sun. The space agency said that 3I/ATLAS will reach its closest point to the Sun around October 30, 2025, at a distance of about 130 million miles (210 million kilometres). It will remain just inside the orbit of Mars. According to reports, 3I/ATLAS is expected to approach Earth in November 2025, but NASA said that it poses no threat to Earth and will remain far away. Who Was Baba Vanga? Baba Vanga was known for her alleged prophetic abilities and accurate predictions, including the Chernobyl disaster and the 9/11 attacks.

Top gastroenterologist ranks common non-vegetarian protein sources
Proteins are vital, but some sources are better than others, according to Dr. Saurabh Sethi. Farm-raised tilapia and deli meats rank low due to their poor nutritional content and harmful preservatives. Wild-caught salmon, sardines, and mackerel top the list for their omega-3s and gut-friendly properties. Your body needs protein. This macronutrient is essential for building, repairing, and maintaining various tissues and bodily functions. In children, teens, and pregnant women, protein is crucial for growth and development. Remember, proteins are the building blocks of life. But are the proteins you eat really fueling your body? Dr. Saurabh Sethi, a Harvard and Stanford-trained gastroenterologist and liver specialist, has ranked some of the most popular non-vegetarian protein sources on a scale of 1–10, based on their impact on gut health, inflammation levels, and overall digestion. Take a look. Proteins with the lowest rankings While proteins are essential for the body, eating the right ones are crucial. Some of the most common non-vegetarian protein sources, which we assume to be healthy, however, scored poorly. Dr. Sethi gave farm-raised tilapia a dismal 2. Though fish is considered a good source of protein, this in particular is low in omega-3 content. Deli meats fare even worse. Dr. Sethi gave score 1 on the scale, as it is loaded with preservatives like nitrates, which can harm gut bacteria and increase inflammation. Some of the commonly consumed proteins have scored minus points on the scale. At the bottom of the scale is fried chicken (-5), hot dogs (-10), bacon (-10), and sausages (-10). These foods are detrimental to gut health. They are ultra-processed and high in saturated fats and additives, which disrupt the gut microbiome and promote inflammation. They are also bad for heart health and brain function. Proteins with mediocre rankings Some of the proteins, which people believe as high-quality protein sources, turned out to be mid-tier options. Shellfish, including shrimp and crab, stand at 6. Though they are nutrient-rich, they can trigger inflammation in some individuals due to allergens or high cholesterol content. Lamb , which is thought to be a good source of protein, however, scored a 5. It has higher fat content, which may strain digestion for some, though it remains a good source of iron and B vitamins. Dr. Sethi ranked beef at 4, as it can increase inflammation, especially when consumed in large quantities or as processed cuts. Tuna stands at 3. This is because its high mercury content can destroy your gut health. The toppers Wild-caught salmon tops Dr. Sethi's list. It earns a perfect 10. Fatty fish such as wild salmon are rich in omega-3 fatty acids. This fish helps reduce inflammation and improve the gut microbiome. Sardines and mackerel follow closely, each scoring 9. They are nutrient-dense and a good source of omega-3s and vitamin D. Eggs, the most popular protein source, stand at 8, thanks to their bioavailability and nutrient density. Chicken and turkey score a solid 7; however, the way you cook it matters. 'Kahin Bada, Kahin Chhota': Ravi Kishan Uses Samosa Analogy To Demand Regulation Of Food Prices

Of 1.4L+ docs in Maha, only 10k opt in for ‘KYD' QR code scheme
Nagpur: Despite Maharashtra Medical Council (MMC) launching a forward-thinking initiative to help patients verify doctors and curb quackery, response from the medical fraternity is far from encouraging. Tired of too many ads? go ad free now Out of over 1.4 lakh registered medical practitioners across the state, only about 10,000 have signed up for the 'Know Your Doctor' (KYD) initiative and received their personalised QR codes, meant to be displayed at their clinics for public verification. This means that a vast majority of clinics still do not provide patients an option to quickly and easily verify whether their doctor is a genuine, licensed professional — something crucial especially in rural and vulnerable areas plagued by fake medical practitioners. Speaking to TOI, MMC administrator Dr Vinky Rughwani from Nagpur said, "This initiative is extremely helpful to patients. They can just scan the QR code displayed in the clinic using their smartphone, and it will directly take them to the MMC portal, where all verified details of the doctor — including specialisation — are available." Maharashtra was the first state in the country to launch such initiative to counter quackery, and after us, many other states as well as councils like homeopathy and ayurveda followed suit. "I appeal to all registered medical practitioners in Maharashtra to come forward and participate in this drive," said Dr Rughwani. Recently, Maharashtra health minister Prakash Abitkar informed the state legislative assembly that the govt is considering making this QR code registration mandatory for all doctors in the state in order to combat the growing menace of quackery. Fraudulent doctors and unlicensed clinics remain a persistent threat to public health in Maharashtra, particularly in districts with limited healthcare access. Patients often fall prey to unqualified individuals posing as doctors. The QR code initiative gives people a powerful, easy-to-use tool to protect themselves — but only if doctors participate. Until more doctors adopt the initiative, patients are urged to look for the KYD QR code in clinics, scan it before proceeding with consultations, and spread awareness about the importance of verifying medical credentials.
