Stress to kidney disorder: Doctor breaks down 4 tremors that are not Parkinson's and how to spot them
In an interview with HT Lifestyle, Dr Shirish M Hastak, Regional Director of Neurology - Stroke and Neurocritical Care at Gleneagles Hospitals in Mumbai's Parel, explained, 'While Parkinson 's-related tremors are well-known, various other conditions can also cause shaking, many of which are not serious or progressive. Seeking early medical consultation can help in proper diagnosis and treatment.'
Dr Shirish M Hastak said, 'Did you know? Tremors are involuntary, rhythmic muscle movements that can impact the parts of the body, mainly the hands, arms, legs, head, or voice. They may occur at rest, during movement, or while maintaining a posture. Tremors can be classified into different types, with Parkinson's tremors being just one category among many. Not all tremors mean Parkinson's disease so please check with your Physician or neurologist.'
Parkinson's disease affects movement, causing symptoms such as tremors, stiffness, and slow movements. However, according to Dr Shirish M Hastak, various other conditions can lead to tremors -
• Essential Tremor (ET): It is often mistaken for Parkinsonism. It usually affects the hands, head, or voice and worsens with movement, unlike Parkinson's tremor, which occurs more prominently at rest.
• Physiological Tremor: Everyone experiences this mild, barely noticeable tremor during exams which can be induced due to stress, fatigue, caffeine, or anxiety.
• Dystonic Tremor: Commonly seen in people with dystonia, a condition that causes involuntary muscle contractions, leading to abnormal movements.
• Conditions like thyroid disorders, liver or kidney disease and low blood sugar levels can also lead to shaking and tremors.
Dr Shirish M Hastak answered, 'Parkinson's tremors improve with movement, whereas essential tremors worsen with movement. Parkinsonian tremors usually start on one side of the body and progress gradually. Other symptoms accompany Parkinson's tremors, such as muscle stiffness, slowness of movement and balance problems.'
Dr Shirish M Hastak shared, 'Neurological examination, MRI or CT scans to check for structural brain issues, Blood tests to examine thyroid, kidney and liver functions. Even Dopamine imaging scans (DaTscan) for detecting Parkinson's disease can be advised to the patient if there is uncertainty about the clinical diagnosis.'
Treatment depends on the underlying cause. Dr Shirish M Hastak, said, 'For essential tremors, medications like beta-blockers or anticonvulsants can help. Lifestyle changes, stress management, and physical therapy can also be beneficial. In severe cases of essential tremors deep brain stimulation (DBS) may be considered. If tremors result from medication or metabolic disorders, addressing the root cause can often resolve the issue. With the appropriate approach, tremors can often be managed, allowing individuals to live without unnecessary fear or stress.'
Talking about how lesioning surgery is also beneficial for some selected patients, Dr Shirish M Hastak said, 'This procedure stands out due to its immediate efficacy, affordability, and longevity. In patients who cannot, use a spoon or a glass due to severe tremors of the hand or the leg, this surgery can improve the quality of life. Lesioning surgery involves creating a small, controlled lesion in a highly targeted brain area.'
He concluded, 'For patients who have struggled chronic symptoms of essential tremors for many years, the results are almost miraculous. Moreover, the reduced cost and shorter recovery time make it an accessible solution for many individuals who cannot afford deep brain stimulation. It represents a significant advancement in functional neurosurgery.'

Diagnosed with terminal cancer at 32, given 100 days to live: Arjun Sen is a 'cancer winner' who never gave up on life
Health is a deeply personal topic, and sharing personal health experiences publicly can be a double-edged sword. On one hand, it can help people feel less alone, build community, and inspire others. On the other hand, it can also expose them to unwanted opinions, unsolicited advice, and harsh criticism. Arjun Sen, 61, believes in the former. Also read | Oncologists reveal who is more at risk of aggressive prostate cancer, explain why early detection is crucial Arjun Sen prefers to call himself a 'cancer winner' rather than a survivor. He believes that winning is about thriving, not just staying afloat. (Instagram/ Arjun Sen) His story is truly remarkable and a testament to the human spirit's capacity for resilience and determination. Diagnosed with terminal cancer at 32 and given just 100 days to live, Arjun defied the odds and lived for over two decades after his diagnosis. What makes his story stand out is his mindset shift and the life he built after his diagnosis. Today, he prefers to call himself a 'cancer winner' rather than a survivor. He believes that winning is about thriving, not just staying afloat. In an interview with HT Lifestyle, Arjun, who inspired Shoojit Sircar's 2024 film, I Want To Talk, spoke about everything he has learnt since his cancer diagnosis. Here are the excerpts: 1. What would be your advice on a healthy mindset and belief during cancer treatment? It's not easy to do, but it takes the same mindset before you or anybody in your family is going through cancer treatment. A very important fact, the mind is always cancer-free, and the mind can get us through. This is incredibly important if somebody in your family is going through cancer because when they talk to you, if they see fear in your eyes and if your care is coming across as empathy, sympathy, it weakens them. Live life cancer-free even during cancer treatment because the mind is always cancer-free. 2. Instead of 'cancer survivor', do you prefer being addressed as 'cancer winner'. If yes, why? I don't prefer, I insist because I am. Because the fact is, there will be one day I will lose, but till that day, I will win. And that is the mindset which is very important. I think when India was playing champions trophy and I think it was either Hardik (Hardik Pandya) or Surya (Suryakumar Yadav) talked about it later when South Africa only needed 30 runs in 30 balls they felt there are teams that have come and won from there nearly impossible in today's IPL and cricket you know T20 format they believed that they are a winner and that's the reason they won otherwise they would have given up the same way I think it's very very important for us to see we can win because the game is over. The moment your shoulders droop and you give up. It's over. And this also makes me appreciate the winds. The winds are not just mine. It's every person around me. And together the fist pump comes out, and I look forward to that next fist bump every day. 3. As family and friends, what do you think is the best way to support someone with cancer? This is tough, not because of what I go through, but because it's harder to watch the people I love face challenges. In that situation, you carry a responsibility. First, don't be in denial. Don't pretend nothing is happening. Acknowledge reality. Second, don't lie to yourself that tomorrow will automatically be better. It might not. Tomorrow could be worse. The day after, even harder. But your love, care, and support must stay constant, unconditional and strong through it all. Third, listen. Let the person speak. You're not an expert, but you're close to their heart. That's powerful. Create a space for them to open up. Help them seek advice, get support, and take steps forward with your presence beside them. And fourth, celebrate the small things. I remember when I started losing my hair. It wasn't about vanity. I've always hand-combed my hair, never used a brush or a comb. What bothered me was the loss of control. So one day, I got some friends together, turned on my favourite movie song, grabbed a buzzer, and we shaved it all off. 'Zindagi hasne gaane ke liye hai pal do pal ise khona nahi kho ke rona nahi'. We created a moment I still carry with me. Challenges like cancer shouldn't define your life or darken every day. Acknowledge them, but don't hand over the reins. Take charge. Smile. Celebrate the time we have because the truth is, life offers no guarantees to anyone, with or without illness. This isn't negativity. It's a deep appreciation for the present. 4. Have you learnt any cancer prevention tips? What do you think people can do daily to reduce cancer risk? This is way beyond my comfort zone. I'm not a doctor or a medical expert. But I needed to ask this question because it's about my daughter. I wanted to know: is she at risk? What are her chances? That's when I started learning. Some risks are congenital. Others come from external factors like exposure to radiation or certain environments. I don't fully understand all of it, but one thing became very clear: you have to do what you can. From what I've learned, even with limited knowledge, family history is crucial. If there's a history of colon cancer, get a colonoscopy earlier. If there's a history of breast cancer, take the necessary steps early on. It's not about living in fear; it's about not living in denial. It's about being prepared if something happens. That readiness matters. And beyond that, maintaining healthy habits, something I didn't take seriously earlier in life, is absolutely essential. 5. Did your experience with cancer change the way you lead teams or approach your professional life? Absolutely. Before I share anything, I want to be clear that this isn't coming from a place of defeat or a negative mindset. I say this with deep appreciation for the present. I live every moment with the awareness that I'm fortunate to be here. Things could've turned out differently, but they didn't, and because I am here, I want to make the most of it. Being present also means recognising that people are not disposable. You can be assertive. You can disagree. But disagree with an idea or an action never with the person. Always maintain care and love for the human being in front of you. That's incredibly important, especially when you're going through difficult times. Another thing I've learned is the importance of self-love. The message was always there every time I got on a plane: Put your own oxygen mask on first before helping others. If I'm choking, I can't help the person next to me. That's not selfish, that's survival. That's love in action. And here's a small, goofy example: every day, I used to think what can I cook for my daughter? What can I make for my wife? Recently, I asked myself: What can I cook for Arjun today? That's me. I'm 61, and I'd never even considered cooking for myself. Now, I do. So be present. Value every person, and that includes yourself. 6. You've worn many hats: author, keynote speaker, marketing leader. How has your personal journey influenced your professional storytelling? Everything changed when I met one of the top professional golfers. I realised that from the age of five or six, he had been putting in nearly 15 hours a day, almost every day, just to maintain and improve his skills. That was an eye-opener. It made me realise that whatever we choose to do, we have to invest in it. That investment is something we owe ourselves because it's rewarding to improve. And we owe it to others because what we give should be worthy of them. One area where this really struck me is storytelling. Earlier, I thought storytelling meant me sitting down and reliving my old memories and you, poor you, having to listen to Arjun ramble on. But that's not storytelling. Storytelling is a gift. It has a purpose. Every story has three parts. What. So what. Now what. What is the story itself about what happened? It might not matter to everyone on its own. So what is the meaning of what I learned from it? Whether it was during cancer, corporate life, or personal challenges what did I take away? But then the power happens, is now what? Now what is I'm bringing to you now what is when I'm sharing to you by saying you know this is what I've learned is if I take it outside me in your life if you similar situations you may be able to do this now that is value to you storytelling is my gift to you and yours to others So there's a bridge, connection and the person can do something with the gift. That's better storytelling. 7. As a leader and mentor, how do you engage with Gen Z employees differently than previous generations? I walk into conversations with Gen Z with a very different mindset. I assume I'm entering a room filled with people smarter than me, people about whom I've had misconceptions, mostly out of ignorance. And it's important to admit: I'm the one who loses if I don't challenge those stereotypes, if I don't correct my lack of understanding. The power today lies with Gen Z. What I've learned is that they're wired differently. But instead of trying to understand that, we often brand them with broad labels: lazy, detached, indifferent. These labels are convenient. They let us avoid doing the work: embracing, approaching, listening, and learning. Let me give you a simple example, and you decide who's wiser. I'm 61 years old. My generation grew up believing retirement came at 60, 65, or 70, whenever corporations or governments told us we'd receive our benefits. That was the plan. That was the box we lived in. Most Gen-Zs I know? They're planning to retire at 42, 45, maybe 50 — on their terms. They want to build a life where post-retirement is not the end, but a celebration. They want to live with intention, not wake up one day with no idea what to do next. So, who's more evolved? You already know the answer. This is why I believe just walking in with an open mind and truly listening has enriched my world. I don't have to agree. I don't have to change. But I do need to be open. And when people in my generation fail to do that, it's their loss, not Gen Z's. 8. What's your message to Gen Z on embracing the 'unquit mindset' in a world of burnout and self-doubt? Let me break it down. First, free yourself from two things. One: you are not responsible for what others do or what's happening around you. If you were, you'd be God. But you're not. You're human. That means you can make mistakes and that's okay. Two: detach from the past. Too often, we dwell on it, try to relive it, or worse, try to change it. Like a batsman who gets out and walks away replaying the shot in his head, thinking, 'If I had moved the bat this way…' it's over. You'll never get that ball again. Go back, practice, learn, and move forward. So, before you embrace the 'unquit mindset', let these two truths sink in: you're not responsible for others' actions which frees you. The past is only useful for two things: learning and celebration, nothing else. Now you're in the present. And here's the reality: adversity is guaranteed. When it comes, there are three things you must build: Resilience, like a punching bag that pops back up each time it's hit. That's your comeback strength. Perseverance: resilience isn't enough. You must also move forward. Get up, shake it off, and keep going. Positivity: sprinkle optimism in your journey. It fuels you and helps you recognise your progress. Together, resilience, perseverance, and positivity create momentum. Appreciate yourself along the way. Prepare. Celebrate even the small wins. Let me leave you with one simple rule: in any situation, act & never react. Reactions are instant and emotional. Acting means pausing, reflecting, and choosing your response. Even if it takes a day or two to wait. It's worth it. When I first learned I had cancer, I didn't react. I went quiet for two days. Sat in darkness. I waited not out of fear, but for clarity. And when I acted, it came from a place of strength. Lastly, remember this: you are never alone. Reaching out is not a weakness. Asking for help is strength. Vulnerability means you've accepted who you are, and that's how you rise. Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.

Cardiologist explains why Indian women's heart health is a 'quiet crisis no one is talking about'
Women's heart health is a 'quiet crisis' that often goes unnoticed, according to cardiologist Dr Vijay D'silva. In an interview with HT Lifestyle, Dr D'silva, medical director of White Lotus International Hospital and clinical advisor and mentor of Heartnet India said 'it is alarming to see the mortality rate in women due to cardiovascular diseases'. Also read | Cardiologist reveals if low blood pressure can trigger heart attack amid Shefali Jariwala's cause of death speculation As per the doctor, schedule annual health screening after the age of 18 to detect any early signs of cardiovascular diseases. (Freeik) 'According to the Global Burden of Disease data, cardiovascular diseases are responsible for 16.9 percent of all deaths in women in India. The way cardiovascular diseases show symptoms in women differs relatively from men. Women often experience chest pain due to mental stress, and they are more likely than men to have a heart attack without chest pain. This can lead them to ignore other symptoms and ultimately not seek medical advice.' Dr D'silva said. Why is women's heart health often overlooked? According to him, there's a lack of awareness about heart disease among women, and it's not just a matter of women being unaware, but also healthcare providers not taking women's heart health seriously enough. He said, 'Heart disease claims more deaths in women than all forms of cancer combined. Despite all this, the awareness of women's heart health and specialised care is excessively low. Doctors may not recognise the minute symptoms early in women as heart-related, which can lead to a delay in the diagnosis of conditions like acute coronary syndrome (ACS), particularly at a younger age or in patients with diabetes. And the exercise stress testing without imaging tests, which is used for the diagnosis of coronary artery disease, has a higher false-positive rate in women.' He added, 'Hence, primary screening should be regularly conducted to detect potential risks and enable early diagnosis. Telehealth services like online consultation can provide expert physician guidance to enable early treatment and even help with preventive treatment and measures to reduce heart risks in women. Heart health in women needs to be prioritised; only then can we begin to reverse the rising number of women's deaths caused by cardiovascular disease.' What can yo do to stay safe? Dr D'silva said a combination of lifestyle changes and preventive care steps must be prioritised to decrease the risk of cardiac diseases. For better heart health in women, annual health check-ups are a must, he said: 'Schedule annual health screening after the age of 18 to detect any early signs of cardiovascular diseases.' Speaking of another step, cardiac risk assessment tools, he added, "Use tools like Prevent calculator for cardiac risk assessment, especially in women with a family history of heart diseases or conditions like diabetes and hypertension." The doctor further listed lifestyle changes you can adopt for better heart health: ⦿ Get proper sleep of 7 to 8 hours daily. ⦿ Avoid the consumption of Alcohol and tobacco. ⦿ Maintain a healthy body weight. ⦿ Incorporate regular physical exercise into your lifestyle. ⦿ Focus on a low-carb diet or Mediterranean diet.

IVF vs IUI: What's the difference, which is better for you or more affordable? Gynecologist explains pros and cons
Are you not being able to get pregnant after years of trying? You might have come across Intrauterine Insemination (IUI) or In Vitro Fertilization (IVF) – both methods of reproductive assistance. While they are meant to make it easier for you and your partner to get pregnant, they both have pros and cons, and a doctor can walk you through what makes the most sense for you, your partner and your unique situation. Also read | World IVF Day: Experts share how sperm freezing is giving men more control over fertility and fatherhood According to an obstetrician-gynecologist, IUI is less invasive, more affordable, and often the starting option for mild infertility, while IVF is reserved for more complex cases and yields higher success rates per attempt. (Freepik) But if you are stressed or confused about these fertility treatments or undecided about seeing a fertility expert, Dr Neelam Suri, senior consultant, obstetrics and gynaecology, Indraprastha Apollo Hospitals, shared in an interview with HT Lifestyle what you need to know about these two popular options for people trying to conceive. She said, 'For individuals and couples facing challenges with conception, Intrauterine Insemination (IUI) and In Vitro Fertilization (IVF) are two of the most common assisted reproductive technologies. While both aim to increase the chance of pregnancy, they differ significantly in procedure, invasiveness, cost, and ideal candidates.' What is IUI? Explaing how it is less invasive than IVF and a relatively quick procedure, Dr Suri said, 'IUI is a relatively simple procedure where prepared sperm is placed directly into the uterus around the time of ovulation. This process is less invasive and typically less costly than IVF, with success rates per cycle ranging from 10–20 percent depending on factors like age and fertility diagnosis. IUI is often ideal for cases of unexplained infertility, mild male factor infertility, or issues with cervical mucus. It is commonly the first-line treatment due to its lower physical and financial demands. Medications to stimulate ovulation may be used alongside IUI, but this can slightly increase the risk of multiple pregnancies, such as twins.' What is IVF? In contrast, IVF is a more complex process involving ovarian stimulation, egg retrieval, fertilization of eggs in a laboratory, and subsequent embryo transfer into the uterus, Dr Suri said, and added: 'IVF is recommended when there are more significant fertility barriers, such as blocked fallopian tubes, endometriosis, severe male factor infertility, advanced maternal age, or when several cycles of IUI have failed. Success rates for IVF are considerably higher, often 40–50 percent per cycle for women under 35, but decrease with age.' IUI vs IVF pros and cons According to Dr Suri, 'the cost per IVF cycle is substantially higher than IUI, and the process is both physically and emotionally demanding, involving more clinic visits, injections, and potential side effects from hormonal medications'. Dr Suri explained, 'Both treatments carry some risk of multiple pregnancies and potential side effects from fertility medications, but IVF allows more control (for example, with single embryo transfer, the risk of multiples can be minimized). Deciding which path is right depends on age, underlying diagnosis, prior fertility history, financial considerations, and the urgency of results. Fertility specialists tailor recommendations based on diagnostic findings and personal preferences, sometimes starting with IUI in simpler cases or turning directly to IVF for more complex or urgent scenarios.' In summary, according to Dr Suri, IUI is 'less invasive, more affordable, and often the starting option for mild infertility', while IVF is 'reserved for more complex cases and yields higher success rates per attempt, balancing greater investment with increased chance of conception'. Ultimately, the choice between IUI and IVF depends on individual circumstances, medical history, and personal preferences, and consulting with a fertility specialist can help determine the best course of treatment for each couple.
