Parkinson's disease is a chronic, progressive neurodegenerative condition that develops as the dopamine-producing nerve cells in the brain's substantia nigra gradually die off. The hallmark symptoms are tremors in the hands and feet, slowness of movement, muscle rigidity, and postural instability — but "non-motor symptoms" such as constipation, sleep disturbances, depression, and reduced sense of smell are also common. Because symptoms begin so gradually, they are easily mistaken for normal aging, which means diagnosis is often delayed.
🇰🇷 Korea According to statistics from the 건강보험심사평가원 (Health Insurance Review and Assessment Service), the number of Parkinson's patients in Korea rose from approximately 126,000 in 2020 to approximately 143,000 in 2024 — an increase of about 14% over the past five years and a sharp 50% increase over ten years. Patients aged 65 and older account for approximately 93% of all cases. 🇺🇸 U.S. In the United States, approximately 90,000 people are newly diagnosed each year, and about 1,000,000 people are currently living with Parkinson's disease. As of 2024, the age-adjusted mortality rate among Americans aged 65 and older was 72 per 100,000 (CDC National Center for Health Statistics), making Parkinson's disease the 9th leading cause of death in that age group.
The cornerstone of Parkinson's management is medication. The most widely used drug today is levodopa, which supplements the brain's depleted dopamine and relieves motor symptoms. Taking it at the same time every day, on schedule, is critically important for the medication to work effectively. 🇰🇷 Korea The 질병관리청 국가건강정보포털 (Korea Disease Control and Prevention Agency National Health Information Portal) advises starting with a low dose, monitoring the response and any side effects, adjusting gradually, and aiming to maintain the lowest dose that does not interfere with daily life. 🇺🇸 U.S. According to the Parkinson's Foundation, approximately 90% of Parkinson's patients cover their medical costs through Medicare, and Medicare Part D covers Parkinson's prescriptions including levodopa and carbidopa. Beginning in 2025, the annual out-of-pocket cap under Part D has been set at $2,000, easing the financial burden of medication costs somewhat.
Exercise is every bit as important a self-management tool as medication. Walking, stretching, and strength training form the foundation, and activities that train both balance and core muscles — such as swimming, tai chi, and yoga — are especially beneficial. 🇺🇸 U.S. The Parkinson's Foundation recommends an exercise plan that incorporates aerobic exercise, strength training, balance and agility work (such as tai chi, dance, and boxing), and stretching. Clinical evidence shows that regular exercise is effective not only for easing slowness, rigidity, and balance problems, but also for improving mood, fatigue, and sleep. It is safest to consult the patient's physician before starting exercise and to begin at an intensity suited to the patient's fitness level and stage of the disease.
Adapting the home environment and establishing a consistent daily routine are equally important. Widening pathways inside the home and installing non-slip flooring and safety grab bars can significantly reduce the risk of falls. Serving smaller, more frequent meals is helpful, and because slowed gut motility can worsen constipation, making sure the patient drinks at least six glasses of water a day and eats plenty of fiber-rich foods is strongly recommended. Keeping medication times, exercise, and mealtimes on a steady, consistent schedule helps reduce anxiety for both the patient and the caregiver.
There are several things caregivers should watch especially closely. Beyond motor symptoms, Parkinson's disease can also bring REM sleep behavior disorder — in which the person moves during sleep — as well as depression and cognitive changes. When any of these non-motor symptoms appear, it is important to communicate them clearly to the neurologist in charge of care. Impulse-control problems related to medication (such as gambling or compulsive spending) can also occur as a side effect of dopaminergic treatments, so any unusual changes in behavior should be reported to the medical team right away. 🇰🇷 Korea Seniors aged 65 and older whose daily functioning is significantly impaired by Parkinson's disease may apply for a rating under the 노인장기요양보험 (National Long-Term Care Insurance), which provides access to in-home visit services and day/night care services. 🇺🇸 U.S. Medicare Part B covers outpatient physical therapy, occupational therapy, and speech therapy, while Part A also covers home health services when medically necessary.
