With India's ageing population set to double by 2050, dementia cases are projected to rise dramatically. According to Dr. Rajesh Venkat Indala, Senior Consultant Neurologist, Apollo Hospitals Visakhapatnam, lifestyle changes can reduce the risk of cognitive decline.
Recent studies confirm that physical exercise not only reduces dementia risk but also slows brain ageing.
Regular physical activity
Exercise increases BDNF (Brain-Derived Neurotrophic Factor), which supports memory retention.
Foods rich in antioxidants, omega-3 fatty acids, and anti-inflammatory compounds are key components.
Healthy diet
In India, diets rich in turmeric (curcumin), leafy greens, lentils, and omega-3 sources like flaxseed align well with principles of the MIND diet.
In India, integrating digital literacy, bilingual learning, and memory games can help keep older adults' brains active.
Mental stimulation
Tailored cognitive exercises based on individual decline patterns can further improve intervention efficacy.
Sleep disturbances are increasingly recognized as an early biomarker for Alzheimer's disease. Improving sleep hygiene through various methods can help promote brain health.
Quality sleep
Social isolation is a modifiable risk factor for dementia. Fostering social interaction through intergenerational programs, group activities like singing or games, and community engagement is crucial in keeping seniors socially active.

Acupuncturist shares 3 dementia preventing hand exercises you should do every day: ‘Take your brain to the gym'
The World Health Organisation (WHO) defines dementia as a syndrome which can be caused by a number of diseases, which, over time, destroy nerve cells and damage the brain, typically leading to deterioration in cognitive function: meaning your ability to remember things and pass judgements. These simple moves done every day help fire up neurons in the brain, boost and maintain coordination, and help keep dementia at bay.(Freepik) Also Read | Neurologist shares 4 unmissable things parents should know to support healthy brain development in kids Several large studies have found that the risk of dementia and Alzheimer's disease increases in people aged 50 years or older. However, training your brain may help slow memory loss and other mental problems. In a post shared on July 25, Anna Seo, licensed acupuncturist and integrative health specialist, shared dementia preventing hacks - 3 hand exercises - that you should practise every day. Tap your fingers, train your brain: 3 dementia preventing hand exercises Sharing the three exercises, Anna wrote, 'Tap your fingers, train your brain! These simple moves done every day help fire up neurons in the brain, boost and maintain coordination, and help keep dementia at bay.' She stressed that taking our brains to the gym after staring at emails and Excel sheets all day is crucially important. 'Your future self will thank you,' she added. Let's find out the exercises she suggested: 1. Alternate clapping To do this exercise, begin by clapping your hands normally for two counts. Then, switch the position by clapping for one count with your palms overturned. Now, do these movements alternatively while changing the position of your palms when they are overturned. 2. Alternating thumb and pinky finger Make fists with both your hands. Now, stick out the thumb of your right hand and the pinky finger of your left hand. Then, change the fingers, with the thumb of your left hand and the pinky finger of your right hand sticking out. Do these movements one after the other. 3. Asymmetrical finger taps For this movement, you have to touch the first digit of your fingers to the thumb, but the movements of both hands will be different. For the right hand, you will begin by touching your finger with the thumb, while simultaneously touching the pinky finger on your left hand. Then, continue moving forward with this asymmetric movement. Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.

Could copper in your diet help prevent memory loss, as new study suggests?
Agency: PTI Loughborough (UK), Jul 27 (The Conversation) More and more research suggests that the copper in your diet could play a bigger role in brain health than we once believed. A recent study found that older Americans who ate more copper-rich foods did better on memory and concentration tests. The findings, published in Nature Scientific Reports, looked at people's diets using detailed food diaries and tested their cognitive function. Those who ate more foods that were high in copper – which include shellfish, dark chocolate and nuts – did better on tests that are used to spot early signs of age-related memory loss and dementia. But the results aren't straightforward. People who ate more copper-rich foods were mostly male, white, married and had higher incomes. They were also less likely to smoke or have high blood pressure or diabetes – all factors linked to a lower risk of dementia. People who consumed more copper also had more zinc, iron and selenium in their diets, and consumed more calories overall. People with higher incomes often have better access to healthy food, medical care, cleaner environments and more education – all of which help protect against memory loss and dementia. It's hard to separate the effects of diet from these other advantages, although some research we reviewed suggests that improving nutrition might be especially helpful for people from less privileged backgrounds. What other research tells us The current study's limitations are notable. It captured brain function at only one point in time and relied on participants' food diaries rather than blood measurements of copper levels. However, long-term studies support the idea that copper might matter for brain health. One study that tracked people over time found that those who had less copper in their diet showed more pronounced declines in memory and thinking. More intriguingly, when researchers measured copper levels directly in brain tissue, they discovered that higher concentrations were associated with slower mental deterioration and fewer of the toxic amyloid plaques characteristic of Alzheimer's disease. Curiously, brain copper levels bore little relationship to dietary intake, suggesting the body's processing of this mineral is more complex than simple consumption patterns might indicate. There's a good biological explanation for why copper might help protect the brain. This essential metal plays several important roles: it helps prevent brain cell damage via antioxidant effects, with production of the chemicals (neurotransmitters) that let brain cells talk to each other, and helps the brain produce energy, by working via particular enzymes. Copper deficiency is thought to be relatively uncommon, but it can cause noticeable problems. If someone feels tired and weak and has anaemia that doesn't improve with iron or vitamin B12 supplements, low copper might be to blame. Other signs can include getting sick more often, losing bone strength, and nerve damage that gets worse over time. Copper is naturally found in high amounts in foods like beef, offal, shellfish, nuts, seeds and mushrooms. It's also added to some cereals and found in whole grains and dark chocolate. People who have had gastric bypass surgery for obesity or have bowel disorders may have trouble absorbing copper – and these conditions themselves could be linked to a higher risk of dementia. It's best to be cautious about taking copper supplements without careful thought. They body needs a delicate balance of essential minerals – too much iron or zinc can lower copper levels, while too much copper or iron can cause oxidative stress, which may speed up damage to brain cells. Studies examining mineral supplements in people already diagnosed with Alzheimer's have shown little benefit. Paradoxically, people with Alzheimer's often have higher copper levels in their blood, but key brain areas like the hippocampus – which is vital for memory – often show lower copper levels. This suggests that Alzheimer's disrupts how the body handles copper, causing it to get trapped in the amyloid plaques that are a hallmark of the disease. Some researchers suggested that after Alzheimer's develops, eating less copper and iron and more omega-3 fats from fish and nuts might help, while saturated fats seem to make things worse. However, a lack of copper could actually increase plaque build-up before dementia shows up, highlighting the need for balanced nutrition throughout life. There seems to be an optimal range of copper for brain function – recent studies suggest 1.22 to 1.65 milligrams a day provides copper's cognitive benefits without causing harm. This mirrors a broader principle in medicine: for many biological systems, including thyroid hormones, both deficiency and excess can impair brain function. The human body typically manages these intricate chemical balances with remarkable precision. But disease and ageing can disrupt this equilibrium, potentially setting the stage for cognitive decline years before symptoms emerge. As researchers continue to unravel the relationship between nutrition and brain health, copper's role serves as a reminder that the path to healthy ageing may be paved with the careful choices we make at every meal.
