What Is a 'Distinguished Physician'?A renowned physician is traditionally defined as 'a doctor known for healing illness well.' But the definition is evolving. Today's distinguished physicians are not only measured by clinical skill and experience — they are also evaluated by their contributions to research, community service, public outreach, and the courage to practice medicine on their own terms.While tertiary university hospitals focus on complex conditions and high-difficulty procedures, primary and secondary care facilities serve as the everyday front line — the first gateway to health for most people. It is in this spirit that Health Kyunghyang has launched a new series, 'The Doctor: Distinguished Physician Report,' spotlighting physicians who have walked a steady path of expertise across all levels of care, evaluated by three core criteria:Evaluation Criteria for 'The Doctor: Distinguished Physician Report'▲ Specialization and depth in their clinical field▲ Evidence-based principles of practice▲ Patient communication and contribution to the communityThe third subject in this series is Dr. Sooyeoun YOU, Neurologist at Seoul Medical Center.Dr. Sooyeoun YOU: Career and CallingNeurology is the medical specialty that diagnoses and treats all diseases related to the nervous system — including Parkinson's disease, dementia, sleep disorders, and stroke. Within that broad field, Dr. You's subspecialty focus is Parkinson's disease, other neurodegenerative conditions, and a range of movement disorders.After graduating from Ewha Womans University School of Medicine, Dr. You trained at Asan Medical Center in Seoul and Keimyung University Dongsan Hospital. In May of last year, she joined the neurology department at Seoul Medical Center — a public hospital — bringing fresh energy to community-based care and building closer, more sustained relationships with her patients.She also serves as Director of Public Relations for the Korean Movement Disorder Society, where she devises creative content campaigns to raise awareness about Parkinson's disease.Dr. Sooyeoun YOU dedicates herself entirely to helping patients and their caregivers fully understand Parkinson's disease and embrace it as a lifelong companion — ensuring the very first step of management is taken right. For patients who put in the effort, she never holds back her praise, always encouraging their determination to keep going."Parkinson's disease is not diagnosed by a single test. You have to keep observing — a patient's facial expression, their gait, the tremor in their hands, and the invisible struggles of the mind. I chose this field because I felt there was so much a doctor could do. I have never regretted that decision." — Dr. Sooyeoun YOUUnderstanding Parkinson's Disease: What Patients Need to KnowParkinson's disease is a progressive neurodegenerative disorder caused by the gradual loss of dopamine-producing cells in a specific region of the brain. Dopamine plays a critical role in regulating body movement — when its production declines, patients experience a characteristic cluster of motor symptoms:Core Motor Symptoms of Parkinson's Disease• Slowness of movement (bradykinesia)• Rigidity — stiffness and resistance in the muscles, making movement difficult and painful• Resting tremor — hands that shake even when still• Stooped posture with one-sided dragging gait• Freezing of gait — feet that feel 'glued' to the floor when starting to walk or changing directionImportantly, these symptoms alone are not sufficient to diagnose Parkinson's disease immediately. Differential diagnosis requires ruling out other underlying conditions. Dr. You emphasizes that the most significant challenge is not the complexity of diagnosis itself — it is that patients and their families simply do not know what this disease is.To bridge that gap, Dr. You draws pictures, brings brain models to the consultation room, and walks patients and caregivers step by step through the role of dopamine, why symptoms appear, and why medication is essential.Dr. You on Setting the Right First Step"Parkinson's is a condition that must be managed for life — there is no concept of a complete cure. But with appropriate treatment, patients can stabilize their symptoms and enjoy an ordinary daily life. That is why it is so important to button the first button correctly: help patients truly understand the disease and learn to manage it in their own lives. Patients who start well feel less anxious — and they manage their symptoms far better on their own."Medication Management: Precision and PatienceDrug therapy is the cornerstone of Parkinson's disease treatment. The key is selecting the right medication for each individual patient — no two patients are the same — and maintaining consistent, long-term adherence while carefully adjusting dosages over time.Treatment options include:▲ Levodopa — directly replenishes dopamine in the brain▲ Dopamine agonists — mimic dopamine's effects to control symptoms▲ Enzyme inhibitors — slow the breakdown of dopamine to extend drug effectivenessA critical issue is that while Parkinson's medications are highly effective, their duration of action tends to shorten with prolonged use — leading many patients to discontinue medication on their own. Dr. You counters this by proactively explaining possible side effects and pre-briefing patients on which medications can be adjusted if symptoms intensify."If a patient arbitrarily stops one drug, I have no way of knowing whether they've improved or worsened because of the medication," she explained. "I draw pictures of each pill — which ones are essential and which can be adjusted — and go through them one by one."'The More Time You Invest, the Better the Outcome'Parkinson's disease is unique: the more time a physician spends with a patient, the better the prognosis tends to be. Since moving to a public community hospital, Dr. You says she appreciates being able to spend real time in the consultation room — something she couldn't always do in a busy tertiary hospital."Some patients ask me: 'Is it really okay to be in here this long?'" she recounted with a smile. "That was something I never heard at a university hospital."On Korea's Need for In-Depth Clinical Care"If the environment in Korea supports in-depth consultations, so-called 'doctor shopping' — moving from clinic to clinic — will decrease. People do that because they are anxious and want to understand their own illness. If a patient walks out of the consultation room with their questions answered and their anxiety resolved — even after just one visit — they leave with lighter steps and come back with more energy."Memorable Patients: Words That StayFor Dr. You, the ultimate goal in Parkinson's care is not dramatic surgical transformation — it is helping patients maintain their daily lives through steady, incremental symptom management. As a result, she says it is not specific cases that stay with her, but the words of individual patients and caregivers.One patient, upon receiving the Parkinson's diagnosis, responded with unexpected cheerfulness: "I was so frustrated not knowing what was wrong — this is such a relief." Another caregiver passed along quiet gratitude on behalf of a patient who was able to understand and manage the illness through to the end of life."When a specialist accompanies a patient with genuine sincerity, it can change not only the patient's thinking, but their entire life," Dr. You said.Dr. Sooyeoun YOU shared that she thinks constantly about how to explain Parkinson's disease — a condition that feels so unfamiliar and daunting to most people — in a way that is simpler and more approachable. She noted that writing, her longtime passion, demands exactly the same kind of thinking, and flashed a bright smile as she said it: in that sense, she has achieved the rare harmony of turning what she loves into what she does.Beyond the Clinic: Author, Artist, and AdvocateDr. You is also a published author — a 'doctor-writer' who has woven medical knowledge into popular culture through four books, blending medicine with film, history, and Greek mythology in plain, accessible language:『The Doctor Who Reads Greek and Roman Mythology』『Why Did the Mad Hatter in Wonderland Go Mad?』『The Doctor Who Went to the Movies』『Life, Death, and Illness: The Three Kingdoms』"Every sentence I labored over to make medical knowledge accessible has helped me explain Parkinson's disease to my patients. I love books, and in a way, my passion and my work have become one," she said with a laugh.She is also a talented illustrator — she personally designed her society's mascot character: a turtle, chosen as both a symbol of longevity and for its characteristically slow gait, representing Parkinson's motor symptoms. The character carries the motto: 'GOOD GAIT, LONG LIFE' — walking well leads to living well — highlighting gait changes as an early diagnostic clue.When the opportunity arises, Dr. You actively participates in medical volunteer activities, bringing her distinctive bright energy to senior patients at barrier-free clinics — relieving their anxiety and, as she puts it, "replenishing dopamine" through her presence.Dr. Sooyeoun YOU's Essential Tips for Parkinson's Patients5 Things Every Parkinson's Patient Should Know1. Get sunlight or change your home environment when you feel exhausted: Sitting in a sunlit space in the morning supports brain cell function and helps prevent depression.2. Never stop medication on your own: Initial side effects from Parkinson's drugs often improve with time — try to adapt before giving up.3. Trust your physician and stay committed to your current treatment: Placing excessive hope in medications not yet available in Korea is less important than managing your body well with what exists now.4. Deep brain stimulation (DBS) surgery should only be considered on expert recommendation: DBS is appropriate only for selected patients — those with difficult-to-control tremors or wide fluctuations in drug response — and only when a specialist judges it necessary.5. Exercise every day: Make morning stretching, aerobic exercise, and strength training a daily habit. Recommended strength exercises include sit-to-stand from a chair, and seated resistance band leg exercises. Equipment at neighborhood exercise parks is also helpful.
