Can a simple diet change reduce chances of dementia, Alzheimer's disease?
WHAT IS THE MIND DIET?The MIND diet, short for Mediterranean-DASH Intervention for Neurodegenerative Delay, is a hybrid of the Mediterranean diet and the DASH diet (Dietary Approaches to Stop Hypertension). But it goes a step further by targeting nutrients specifically linked to brain health and cognitive function.Key brain-boosting components of the MIND diet include:Flavonoids and polyphenols from fruits, vegetables, tea, and dark chocolateFolate from leafy greens and legumesOmega-3 fatty acids from oily fish, seeds, and nutsCompared to general healthy eating guidelines, the MIND diet places special emphasis on daily consumption of green leafy vegetables and weekly servings of berries and fish foods known to nourish neurons and reduce brain inflammation.STUDY HIGHLIGHTS: MIND DIET STANDS OUTResearchers scored participants' diets using four systems: Mediterranean Diet Adherence Screener (MEDAS), MIND Diet Score, Recommended Food Score (RFS), and the Alternative Healthy Eating Index (AHEI)The MIND and RFS diets showed the strongest associations with lower dementia risk, while a higher score on the Energy-adjusted Dietary Inflammatory Index (EDII), which reflects diets high in processed and inflammatory foods, was linked to a 30% higher risk of dementia.'The associations between dietary patterns and dementia were stronger in older adults and women, and varied by obesity status, highlighting how diet affects different populations differently,' the researchers noted.FOOD AS PREVENTION, NOT JUST NUTRITIONThis study reinforces findings from earlier research. For instance, a previous trial of 906 older adults found that those with higher MIND diet scores experienced slower cognitive decline over nearly five years.Another autopsy-based study of 581 participants revealed that those who had followed the MIND or Mediterranean diet had fewer amyloid plaques in their brains, a biological hallmark of Alzheimer's disease.In both studies, higher intake of leafy greens was the most protective dietary factor.NO CURE, BUT PREVENTION IS POWERFULWith no definitive cure for dementia, researchers stress the urgency of prevention-focused interventions, particularly diet.advertisement'Our findings underscore the potential of dietary interventions as modifiable factors to reduce the risk of dementia, especially in vulnerable populations,' the authors wrote.They also noted that unlike earlier studies, this research compared multiple dietary patterns and followed participants for more than a decade, providing robust, long-term insights.SO, WHAT SHOULD YOU EAT TO PROTECT YOUR BRAIN?To follow the MIND diet, here's a simple roadmap:Eat more of:Leafy greens (daily)Berries (more than two days per week)Whole grainsNuts and seedsLegumesFish (once a week)Poultry (at least twice a week)Olive oil as main cooking fatLimit these foods:Red and processed meatsButter and stick margarineCheesePastries and sweetsFried and fast foodsWith science uncovering more about the links between food and brain health, one thing is becoming clear: what's good for your heart is often good for your head.While no single diet guarantees immunity from cognitive decline, the MIND diet could be practical, sustainable with strong evidence to nourish your brain.- Ends

World Brain Day 2025: Why your brain deserves the spotlight today
World Brain Day was initiated by the World Federation of Neurology (WFN), marking the organization's foundation day which now sees a worldwide participation from doctors, scientists, policymakers, patient advocates and individuals from across the globe. Tired of too many ads? go ad free now Each year, World Brain Day is celebrated with a specific theme imparting a conscious effort to understand the importance of neurological care. This year the theme is, 'Brain Health for All Ages', which underscores the 12 annual celebration of the event, emphasizing that brain health is not a fleeting concern- it's a commitment spanning from the womb to the young age and then to the old age. The journey to brain wellness begins from the day the fetus starts growing in the womb, which is shaped further by parental care, nutrition and eating habits, lifestyle and most importantly, the environment in which we live. Every stage- from infancy, childhood to the old age period, our neurological system and even our body demands mindful care and proactive habits for proper growth and development. As it is rightly said by Prof. Wolfgang Grisold, President of the World Federation of Neurology (WFN)- 'Brain health isn't a moment in time—it's a lifelong commitment. World Brain Day 2025 is our call to action to protect neurological well-being from the earliest stages of development, through childhood, adulthood and into older age. It's a commitment to care, equity, and access for all.' Brain Day celebration isn't just an initiative; it's the most important tool in any human's body. Just imagine for a moment, every thought we have, our feelings, our emotion, our understanding that channels decision making in our life- everything matters on our comprehending skills. So, who channels it- obviously it's our brain- a three- pound intricate marvel nestled within our skull. Tired of too many ads? go ad free now At present time, we are surrounded with a lot of technological advancement and with those complications have also led its way, mental health has become a prominent issue. And brain function is one of the components which matters more than ever, when it comes to mental health issues. Why? Because everything starts from the brain as it comprehends the meaning which further leads to mood swings, mental intake of a particular situation. At present, we need to take it seriously because neurological disorders are now the leading cause of disability- adjusted life years (DALYs) globally, which is the second leading cause of death after heart disease. New research links unhealthy lifestyle habits, environmental toxins and poor nutrition surge in conditions like Alzheimer's, depression, Parkinson's etc. Yet, despite these sobering realities, people are not properly educated about the importance of neurological health, funding for neurological research is woefully inadequate compared to other diseases. The reason behind includes lack of knowledge, awareness and prioritization. So, every year, World Brain Day is celebrated as an initiative to bridge the knowledge gap by placing the brain squarely in the spotlight, igniting global conversations, and urging immediate action. It should be taken as a public health priority, because if we count in numbers, over 1 billion people worldwide live with a neurological disorder. As we traverse the modern landscape, marked by technological growth with a greater life expectancy, we need to figure out a way for better brain cell growth, because the health of our brains determines the destiny of individuals and a better family. The conversation is urgent, so the call and action must be taken promptly- Brain should be for all ages and a key priority. As per the Harvard Medical School, the human brain contains approximately 86 billion neurons forming about 100 trillion connections—networks so complex that they dwarf the capabilities of the human mind to fully comprehend. New fields like connectomics aim to map these tangled networks to understand how different regions and cells work together to produce thoughts and behaviors. According to various reports and research studies, the human brain gets smaller as we get older and it keeps on developing until our late 40s, the fun fact is the human brain is the largest brain of all vertebrates relative to body size and it triples its size in the first year of life approximately to 80% by two years of age. As referenced in Scientific Americana study, 'if the brain worked like a digital video recorder, 2.5 petabytes would indeed suffice to hold three million hours of television, meaning we'd have to watch TV continuously for more than 300 years to fill it up.' This super-computer consumes about 20% of the body's energy, despite being made of nearly 75% water, the brain is more efficient than any existing computer, processing information faster than the fastest computers. So, this July 22, let's come together not just for brain development, but for a better healthy lifestyle. Because a healthier brain is not just about personal wellness—it is the root of flourishing communities and a thriving world.

Beyond memory loss: The lesser-known dementias that deserve attention
When people hear the word dementia, they are very likely to immediately think of Alzheimer's disease. And while Alzheimer's is the most common form, accounting for 60 to 80 % of cases worldwide, it is far from the only type of dementia. A range of other, lesser-known dementias can be equally devastating, and recognising them early can lead to better care and improved quality of life. So, what are these lesser-known types of dementia? Vascular Dementia Vascular dementia is the second-most common type of dementia, and is estimated to be about 40 % of all dementia cases in India. It is triggered by reduced blood flow to the brain, often after strokes or due to chronic conditions such as hypertension and diabetes. Its sudden onset, rapid decline or step-by-step decline after 'mini strokes', and link to future strokes, makes this type very dangerous. However, unlike Alzheimer's, it's often preventable. Early diagnosis, blood pressure and sugar control, and a healthy lifestyle can delay its progression. Frontotemporal Dementia Sometimes misdiagnosed as a psychiatric illness, frontotemporal dementia (FTD) is an umbrella term for brain disorders that affect the frontal and temporal lobes of the brain. These sites are associated with personality, behaviour and language, and thus some people undergo personality changes or become more impulsive or emotionally indifferent when suffering from this condition. About 60 % of people diagnosed with FTD fall within the age bracket of 45 to 64. Currently, there is no cure for FTD. In addition to this, because it affects a younger age group than Alzheimer's usually does, it becomes extremely distressing for families and often leads to early dependency and care needs. Lewy Body Dementia Lewy body dementia (LBD) is marked by abnormal protein deposits in the brain that disrupt both cognitive functions and physical abilities. It causes problems with coordination and balance, vivid visual hallucinations, muscle stiffness, difficulties with concentration, memory issues and severe sensitivity to certain medications. Due to the symptoms intersecting with other kinds of dementia, it is tricky for doctors to lock down on the diagnosis. Multiple tests are required to diagnose LBD. While there is no cure for this kind of dementia, medical and non-medical treatments such as physical and occupational therapies are recommended to keep symptoms in control as much as possible. Creutzfeldt-Jakob disease Creutzfeldt-Jakob disease (CJD) is a rare but devastating brain disorder caused when a type of protein, prions, undergo a change. While the symptoms of CJD are very similar to those of Alzheimer's, this disease usually gets worse faster and leads to death. Though only one or two cases of CJD are diagnosed per million people around the world, its aggressive progression and lack of a cure make it especially alarming. Mixed dementia Mixed dementia is a blend, most often Alzheimer's disease combined with vascular dementia, and sometimes Lewy body dementia and other types of dementia. This mix leads to overlapping symptoms, and hence, no definitive symptoms are associated with it. A report states that at least one in 10 people with dementia is diagnosed as having mixed dementia. This diagnosis is confirmed only when the doctor finds clear signs of at least two different types of dementia. Why awareness matters Alzheimer's, vascular dementia, Lewy body dementia, frontotemporal dementia, and Creutzfeldt-Jakob disease each have unique causes, symptoms, progression, and treatment responses. Identifying the correct type helps doctors tailor care to individual cases, whether it is medication, lifestyle changes, or managing stroke risk. It also helps families understand what to expect – memory loss vs. personality changes, gradual vs. sudden decline. Without an accurate diagnosis, people may miss out on treatments that could ease symptoms or slow progression. Awareness is the first step towards better outcomes and quality of life. Memory loss is just one piece of the dementia puzzle. If you or a loved one is experiencing unexplained behavioural changes, sleep disturbances, or movement issues, talk to a healthcare provider. Dementia isn't one-size-fits-all, and knowing the differences could change the course of care. (Dr. Usha Humbi is a consultant neurologist at Narayana Health City, Bengaluru.

5 supplements a neurosurgeon takes to protect the brain
Dr. Arun L. Naik suggests supplements for brain health. Magnesium supports learning and memory. DHA is vital for brain cell structure and mood. Vitamin B12 prevents neurological issues. Creatine boosts brain energy and memory. Vitamin D regulates mood and protects against decline. These supplements can improve overall brain function. Consult a doctor before starting any new supplement. Keeping the brain in good shape is crucial for overall wellness. From controlling movement and emotions to coordinating many vital functions, the brain is responsible for some of the most complex tasks in the body. The brain requires certain nutrients for proper functioning. Dr. Arun L. Naik, a leading neurosurgeon trained at All India Institute of Medical Sciences (AIIMS), New Delhi, has now shared a list of supplements he takes to protect his brain. Let's take a look. Magnesium Magnesium is an essential nutrient for the brain. Dr. Naik explained that this nutrient supports synaptic plasticity, which is essential for learning and memory. Magnesium L-threonate supplements, in particular, cross the blood-brain barrier effectively and thereby improve synaptic plasticity, which is essential for strengthening neural connections. Magnesium supplements regulate neurotransmitters like glutamate and GABA. Along with improving brain health, magnesium supplements may also reduce stress, improve sleep quality, and lower the risk of age-related cognitive decline. Magnesium has also been shown to be effective in reducing anxiety. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 3BHK Transformation Possible for ₹4.5 Lakh? HomeLane Get Quote Undo DHA Second supplement on the neurosurgeon's list is DHA - Docosahexaenoic acid. This is an omega-3 fatty acid that constitutes 25% of the brain's fat. DHA is essential for cell membrane integrity and neuronal communication. According to the doctor, this supplement supports cognitive function and mood stabilization. Its anti-inflammatory properties also reduce the risk of Alzheimer's and dementia. Vitamin B12 Despite its importance in brain health, people tend to ignore the deficiency of vitamin B12. This nutrient plays a crucial role in nerve myelination, DNA synthesis, and red blood cell production. A deficiency in vitamin B12 can lead to serious neurological symptoms, including memory loss, fatigue, and nerve damage. Vitamin B12 is primarily found in animal products; however, supplementation may be required if your diet is plant-based. Creatine People tend to associate creatine with fitness, for its role in providing energy to the muscles. However, this compound is also essential for the brain cells. Creatine replenishes ATP, the brain's energy currency, especially when under stress or is sleep-deprived. Dr. Naik also stressed that this compound can boost memory in the short term, and also improve reasoning and prevent from mental fatigue. 'Benefits vegetarians (low dietary intake) and may protect against neurodegenerative conditions like Parkinson's,' he added. Vitamin D There is a reason why your mum asks you to get some sunlight every day. Vitamin D is an essential nutrient that also plays a crucial role in the brain. It acts as a neurosteroid with receptors throughout the brain. The neurosurgeon adds that this nutrient regulates mood (linked to serotonin production) and protects against neurodegeneration. Low level of vitamin D is often associated with depression, cognitive impairment, and increased Alzheimer's risk. 5 Signs you are having too much Vitamin D
