Just 5 seconds to detect stroke, dementia, and Alzheimer's disease! Here's how you can do it at home
Imagine checking your brain's health, right at home, but with a quick twist. Just five seconds and a little pinky finger magic are all that you need. It sounds quirky, laughable to some extent, even! But experts say this 'pinky finger test' might offer clues about your risk of stroke, dementia, or even Alzheimer's.
What is it, and how can you perform it at home?

Risk of stroke, dementia, and Alzheimer's disease detection made easy!
Enter the
Pinky Finger Test
!
What is it? This simple (and viral) test asks you to perform a tiny movement with your little finger, often linking fingers or isolating the pinky, for just a few seconds. If it moves freely, you're 'good.' But if it struggles or freezes, some say you might be at risk of stroke or dementia, especially Alzheimer's.
What does science say?
Finger dexterity and brain health:
Research
shows that hand and finger function, especially fine motor skills, have close ties with cognitive performance. In systematic reviews, reduced hand dexterity and grip strength are strongly correlated with cognitive decline and Alzheimer's dementia. Simple hand-motion tasks, like using a pegboard, often show clear differences between healthy older adults and those with Alzheimer's.

For instance, the
Halstead Finger Tapping Test
has long shown that slower or irregular tapping may point to brain dysfunction like TBI or neurological injury.
Finger-tapping as a biomarker:
A
study
from neuropsychologists found that the rhythm, speed, and regularity of finger tapping differed significantly between healthy individuals, those with mild cognitive impairment (MCI), and those with Alzheimer's. The computer-based test could correctly classify participants about 70% of the time, suggesting that irregular finger tapping could be an accessible early biomarker.
Another
recent study
using a magnetic-sensor finger-tapping device found that people with mild cognitive impairment (often a precursor to dementia) had noticeably different finger movement patterns. Using a fancy classification model, researchers achieved an F1-score of about 0.795, quite accurate!
Sensitivity for neurological damage:
Other work shows that quick finger taps, particularly against the thumb, can flag central nervous system issues, like lesions. One
study
highlighted a sensitivity as high as 84% when tested with the non-dominant hand tapping against the thumb crease.
Should you try it at home?
Absolutely, but wisely. Here's how.
Keep it playful. Try bending, isolating, or tapping your pinky. Notice if it's smooth or awkward.
Use it as a cue. If movements feel unusually slow or jerky, consider speaking to a healthcare provider, especially if other symptoms appear.
When you're doing the test, combine with other signs like memory lapses, confusion, or balance trouble matter more. This test can help tip you toward a professional evaluation.
However, don't self-diagnose. Even if the test feels hard, there are many harmless reasons, like arthritis or nerves.
Is it a substitute for medical screening?
There's no other way to say it, but NO; Not At All.
Here's the truth: although there are promising results, medical literature hasn't officially validated the viral "pinky test." It's more anecdote than evidence; no published studies link it to dementia or stroke risk. But the concept behind it has merit.
Fine motor function (like tapping or dexterity tests) does reflect broader neurological health.
Moreover, it's fun, simple, but not a diagnostic powerhouse. The pinky finger test hinges on the broader idea that subtle motor changes can reflect early cognitive shifts. However, it's not clinically validated on its own. These movement tests are not replacements for medical diagnosis; they best serve as an early cue to seek professional evaluation.
It is imperative to remember that the pinky test is a screening tool; think of it like noticing a light flicker, not diagnosing a blackout.
To sum it up…
The pinky finger test may seem fun and quirky, but it taps into real science: fine motor skills reflect cognitive health. Researchers view them as useful 'first steps,' especially since advanced imaging (like MRI or PET scans) can be expensive and less accessible. When combined with established tests and observations, it could gently flag when something deserves more attention.
HOWEVER, the pinky finger test is not a medically validated diagnostic tool and should not be used to confirm or rule out any health condition. If you have concerns about stroke, dementia, Alzheimer's disease, or any other medical issue, please consult a qualified healthcare professional for proper evaluation and advice.

From jaggery to jamun: 10 natural Indian sweeteners and how to use them
Sugar has had its moment, and honestly, it's been a little too long. While we're all for the occasional gulab jamun or halwa, there's a whole range of natural Indian sweeteners that don't just satisfy a craving but also come with their own set of benefits. These aren't just 'healthier sugar substitutes', they're deeply woven into our food traditions, offering flavours, textures, and aromas that plain old white sugar could never match. Here's a tour through some of India's sweetest treasures, plus ideas on how to work them into your kitchen without going overboard. Jaggery , the earthy classic Calories (per tsp / 4g): 15–16 kcal Nutrients: Iron, magnesium, potassium, small amounts of B vitamins Made from sugarcane juice or palm sap, jaggery gives a deep caramel flavour and is less processed than refined sugar. It still raises blood sugar but offers trace minerals. Use it to sweeten chai, melt into sesame laddoos, or stir into sambhar for balance. Coconut sugar , mellow and mineral-rich Calories: 15 kcal (per teaspoon) Nutrients: Iron, zinc, potassium, inulin (a prebiotic fibre) Made from the sap of coconut palm flowers, it has a lower glycemic index (35) than white sugar (65). Works well in kheer, porridge, or baking – but calorie content is similar to sugar, so portion control matters. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo Honey, liquid gold Calories: 21 kcal (per teaspoon) Nutrients: Antioxidants, small amounts of vitamin C, manganese, trace enzymes Honey's not just for toast, it's basically sunshine in a jar. Sweet, mellow, a little floral, and somehow good for you too. Spoon some over chilled dahi, swirl it into warm (not boiling) herbal tea, or brush it on veggies before roasting so they come out all golden and sticky. Date syrup, thick and wholesome Calories: 20–21 kcal (per teaspoon) Nutrients: Potassium, magnesium, calcium, fibre Blend dates with a bit of water and you get a thick, sweet paste full of goodness. Tastes great in smoothies, on pancakes, or holding energy bites together – but it's rich, so just use a little. Palm jaggery , darker, deeper, richer Calories: 15–16 kcal (per teaspoon) Nutrients: Iron, calcium, phosphorus Down south, people love palm jaggery for its deep, smoky sweetness. It's less processed than regular sugar and tastes amazing in payasam, millet porridge, or even a chilled coconut water sherbet. Stevia leaves, green and guilt-free Calories: 0 kcal Nutrients: None significant (pure leaf powder has trace antioxidants) Stevia is a natural, calorie-free sweetener from plant leaves. Extremely sweet – use tiny amounts. Works well for chai, iced teas, or lemonade without affecting blood sugar. Figs, the chewy sweetener Calories: 10 kcal (per dried fig) Nutrients: Fibre, potassium, calcium, magnesium Blended figs can replace sugar in chutneys, curries, or baked goods. They add sweetness plus bulk from fibre, slowing sugar absorption. Jamun honey , a summer special Calories: 21 kcal (1teaspoon) Nutrients: Antioxidants, trace minerals; may help moderate blood sugar spikes Bees that feast on jamun flowers make this tangy, fruity-tasting goodness. It can jazz up plain yogurt, make oats taste fancy, and melt into a hot roti like pure magic. Raisins, tiny flavour bombs Calories: 12–13 kcal (per tbsp / 9g) Nutrients: Fibre, iron, potassium, antioxidants When simmered in milk or chutneys, raisins release gentle sweetness without added sugar. Blend into smoothie bowls or stuff into parathas for a traditional touch. Khus syrup, cooling and fragrant Calories: 18–20 kcal (depends on sugar concentration) Nutrients: Trace minerals from vetiver root; mostly sugar-based calories Made from vetiver roots, it's more about aroma than intense sweetness. Best in sherbets, faloodas, or iced coffee – keep portions small as most versions contain added sugar. Sweet, but smart Natural doesn't mean limitless. Even the most wholesome sweeteners can pile on calories if you go overboard. The trick is to use them where their flavour truly shines – that way, you'll need less and still get maximum satisfaction.

Dharali flash flood changes Bhagirathi course, river returns to old path
1 2 Dehradun: The flash flood in Dharali earlier this week reshaped the course of the Bhagirathi river, widening stream channels and altering river morphology, satellite images from the Indian Space Research Organisation (Isro) showed. The high-magnitude flood eroded a debris fan on Kheer Gad — a tributary of the Bhagirathi located just upstream of Dharali village — forcing it back to its earlier path and pushing the Bhagirathi towards the right bank. Satellite imagery from Isro's Cartosat-2S, comparing data from June 2024 and Aug 7 this year, revealed a vast fan-shaped debris deposit roughly 20 hectares in size — measuring about 750m by 450m — at the confluence of Kheer Gad and the Bhagirathi, just above Dharali. These images showed extensively altered river channels, submerged or buried buildings, and major topographical shifts. Piyoosh Rautela, senior geologist and former executive director of Uttarakhand State Disaster Management Authority, said pre-disaster images revealed a triangular debris fan on Kheer Gad's left bank, just downstream of its confluence with the Bhagirathi. "This deposit was formed during a previous catastrophic downslope movement that diverted Kheer Gad's course at the time. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like If You Have Arthritis Avoid This Food Active Life Journal Learn More Undo Traditionally, such deposits were only used for agriculture, with homes built on higher, stable ground to avoid landslide and flood risk," he said. He added that rapid tourism growth and the pilgrim influx over the last decade, along with commercial activity near the road, had prompted settlement on the alluvial fan. "The flash flood eroded the entire fan deposit and Kheer Gad reclaimed its previous course. Currently, the debris has pushed the Bhagirathi's flow towards the right bank, but it will eventually erode this deposit in time," he said. Hydrologists warned that such sudden geomorphic changes could have cascading effects far downstream. Altered river channels can increase flow velocity, change sediment transport, and destabilise banks kilometres away from the flood site. Over time, this can create new erosion hotspots, threaten bridges, and change floodplains, forcing riverside communities to adapt to a new hydrological pattern. Dean at the School of Environment and Sustainability in Bangalore-based Indian Institute for Human Settlement, Dr Jagdish Krishnaswamy, who is an ecohydrologist and landscape ecologist, said the Himalayas' geology and climate make them prone to such shifts. "These are the world's youngest mountains — tectonically active, geomorphologically dynamic, and generating some of the highest sediment loads globally. Glacier retreat, both natural and intensified by warming, releases vast amounts of debris, which intense rainfall can mobilise into avalanches and mudslides. This sediment can drastically alter river courses, especially where loose deposits exist on lower slopes or in narrow valleys," he said. He cautioned that embankments and retaining walls often give a "false sense of security" when infrastructure and homes are built on unstable ground. "Given the Himalayas' dynamic geomorphology and the increasing intensity of rainfall, extreme caution is needed in designing and locating any infrastructure. Otherwise, we are exposing people and assets to unacceptably high risk," he said. Stay updated with the latest local news from your city on Times of India (TOI).

Harvard doctors' surprising ranking: The best and worst foods for fatty liver
The liver is often one of the most overlooked organs in the body. It quietly performs over 500 essential functions — from detoxifying blood to breaking down fats and processing nutrients. However, modern eating habits, high in sugar, processed fats, and quick-fix meals, are placing immense strain on this vital organ. Fatty liver disease, once thought to affect mainly heavy drinkers, is now increasingly seen in non-drinkers as well. This silent condition is becoming more widespread in India and globally. Productivity Tool Zero to Hero in Microsoft Excel: Complete Excel guide By Metla Sudha Sekhar View Program Finance Introduction to Technical Analysis & Candlestick Theory By Dinesh Nagpal View Program Finance Financial Literacy i e Lets Crack the Billionaire Code By CA Rahul Gupta View Program Digital Marketing Digital Marketing Masterclass by Neil Patel By Neil Patel View Program Finance Technical Analysis Demystified- A Complete Guide to Trading By Kunal Patel View Program Productivity Tool Excel Essentials to Expert: Your Complete Guide By Study at home View Program Artificial Intelligence AI For Business Professionals Batch 2 By Ansh Mehra View Program To help separate fact from fiction, Dr. Saurabh Sethi — a Harvard- and Stanford-trained liver specialist — has ranked some of the most common and healthy foods from best to worst for managing fatty liver. Here's his list, along with the reasoning behind each ranking. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Victoria Principal Is Almost 75, See Her Now Reportingly Undo Store-bought juices Even those labelled '100% fruit' are often stripped of fibre and loaded with fructose and added sugars. Without fibre, sugar is absorbed too quickly, leading to fat build-up in the liver. Dr. Sethi ranks this as the worst food for fatty liver, as the excess sugar 'eventually turns into fat, worsening fatty liver.' Live Events Fresh fruit juice Though better than packaged versions, freshly squeezed juices still lack fibre. The quick fructose hit, even from natural sources, can encourage liver fat accumulation. Whole fruits are a healthier choice than their juiced form. Overripe bananas These have a higher glycaemic index and more sugar. While not inherently harmful, for those with fatty liver, sugar spikes can add extra strain. Pairing bananas with protein or fibre can help slow the sugar impact. Sugar-heavy smoothies It depends on the ingredients. Many store-bought or café smoothies contain sugary fruits, syrups, or ice cream. As Dr. Sethi warns, such blends can 'actually accelerate liver fat build-up.' Without careful choices, what seems like a health drink can turn into a liver burden. Green tea Supported by research, green tea is rich in catechins that help lower liver inflammation and may reduce fat levels. Dr. Sethi ranks it highly for its antioxidants, which aid liver regeneration. However, more than 4–5 cups a day should be avoided. Beets Packed with betaine, beets may assist liver detox pathways and reduce oxidative stress. Dr. Sethi recommends them for those with fatty liver, whether eaten raw, juiced, or roasted. Berries Berries such as blueberries, raspberries, and strawberries are loaded with polyphenols and anthocyanins, linked to improved liver health and reduced inflammation. Their low sugar and high fibre content make them a top choice. Chia and basil seeds Dr. Sethi notes these seeds expand in water, helping slow sugar absorption and lower cholesterol. Their omega-3 fats and fibre indirectly support liver health by boosting metabolic function. Just a spoonful in water or a smoothie can be beneficial. Avocados Rich in monounsaturated fats and glutathione, avocados support liver function. Dr. Sethi ranks them highly for reducing inflammation and improving good cholesterol. They remain underused in Indian diets but are worth adding in moderation. Black coffee Black coffee (without sugar or milk) has liver-protective effects backed by numerous studies. It may reduce the risk of liver fibrosis and improve enzyme levels. Dr. Sethi calls it the best for fatty liver when made with quality beans and consumed in moderation. [With TOI inputs]
