Traditionally considered a condition affecting the elderly, PD is now increasingly diagnosed in individuals as young as their 20s and 30s. A 2022 report by the National Institute of Mental Health and Neurosciences (NIMHANS) revealed that nearly 40–45% of PD patients in India develop motor symptoms between the ages of 22 and 49. This is nearly a decade earlier than the global average, indicating a demographic shift in the disease's onset. 

The British Medical Journal projects that by 2050, approximately 25.2 million people worldwide will be living with PD—a 112% increase from 2021. South Asia, including India, is expected to account for 6.8 million of these cases. Factors contributing to this surge include population aging, growth, and changes in disease prevalence. 

In India, PD prevalence currently ranges from 15 to 43 per 100,000 people. However, the increasing incidence among younger individuals is concerning. Experts suggest that environmental factors, genetic predispositions, and lifestyle changes may be contributing to this trend.

While there is no cure for PD, early detection and a multidisciplinary approach—including medication, physical therapy, and psychological support—can help manage symptoms and improve quality of life. Neurologists emphasize the importance of awareness and prompt diagnosis to mitigate the disease's impact on younger populations.
