Parkinson’s disease in India: Learn about the rising prevalence of Parkinson’s disease among young people and explore common myths about its symptoms and treatment.

When most people think of Parkinson’s disease, they imagine an elderly person with trembling hands. The image is not wrong, but it is dangerously incomplete. Parkinson’s disease is a progressive neurological disorder that over time causes a person to lose the ability to move, speak, and function independently. In India, it is coming sooner than most people think. Recent data from the 6th International Annual Symposium-2026 held in Kerala indicates that India is poised to have the second-highest number of Parkinson’s disease cases in the world within five years due to the increasing trend of young-onset Parkinson’s disease (YOPD).
What are the diagnostic criteria for Parkinson’s disease?
The belief that Parkinson’s disease only affects older people is one of the most persistent and harmful misconceptions in neurology. According to the International Parkinson’s Disease and Movement Disorder Society, the average age of onset of Parkinson’s disease in India is 51 years old, nearly a decade younger than in many other countries.
The incidence of the disease in India has risen sharply, from 15 to 43 per 100,000 people, and the number of infections is expected to rise until 2030. This is alarming because in India, 40-45% of cases occur between the ages of 22 and 49, according to Health Science Reports.
What is early-onset Parkinson’s disease?
This early onset is no coincidence. A multicenter study across India published in 2025 by the International Parkinson’s Disease and Movement Disorders Association found that the younger the age at onset of disease in Indian patients, the higher the genetic risk, and that further investigation is needed. Genetics alone doesn’t tell the whole story. In India, environmental factors such as exposure, pesticide use, and chronic stress also play a role.
How does early-onset Parkinson’s disease develop?
“Early-onset Parkinson’s disease is difficult to detect because early signs often resemble fatigue or muscle tightness, such as slight slowness, decreased arm swing, changes in handwriting, deeper voice, or stiffness on one side,” neurologist Dr. Manish Kulshrestha tells Healthshot. Non-motor symptoms, such as sleep disturbances, constipation, anosmia, and depression, often appear years before motor signs appear, but rarely provoke a neurological examination.
What does Parkinson’s disease actually do?
Parkinson’s disease occurs when dopamine-producing neurons in the substantia nigra progressively degenerate. “Dopamine is essential for smooth, coordinated movements. When dopamine levels are low, characteristic symptoms appear, such as tremor at rest, rigidity, slowness of movement, and postural instability. There is no cure for this disease, but it is manageable, especially if detected early,” says the neurologist. Current treatments include levodopa medication, physical therapy, speech therapy, and in more advanced cases, deep brain stimulation, which delivers electrical impulses to reduce motor symptoms. Early diagnosis is essential for effective intervention.
Can essential tremor progress to Parkinson’s disease?
Another common misconception is that tremors always mean Parkinson’s disease. The reality is that this is not the case, as essential tremors, medication side effects, thyroid dysfunction, anxiety, and more can cause tremors. “Parkinson’s tremor is usually a rest tremor that improves with exercise, rather than worsening with exercise. Only a movement disorder specialist can tell the difference,” Dr. Kulshrestha says. Similarly, the idea that Parkinson’s disease is purely a movement disease underestimates its impact. Depression, cognitive changes, urinary dysfunction, and autonomic dysfunction are all part of the clinical picture and require active management.
What is the prevalence of Parkinson’s disease in India?
According to the Annual Report of the Indian Society of Neurology, there are nearly 1-1.5 million people living with Parkinson’s disease in India, and the prevalence is expected to increase significantly in the coming years. Waiting for older patients with classic tremor before considering diagnosis is an outdated approach. “Just as the urgency of early detection now applies to diabetes, any disease that involves persistent changes in movement, speech, or posture in people over 30 years of age requires evaluation. The sooner the conversation begins, the more meaningful the results will be,” the experts explain.
