Comprehensive Overview of Parkinson's Disease and Its Treatment in India

Understanding Parkinson's Disease (PD)

Parkinson’s Disease (PD) is a chronic and progressive neurodegenerative disorder that significantly impacts movement control due to the brain's reduced ability to produce dopamine. Although there is currently no cure, various treatment options exist to alleviate symptoms and improve the quality of life for patients. Dr. V.P. Singh, a prominent figure in neurosurgery at Medanta, Gurugram, offers insights into the evolving treatment landscape for PD in India.

Prevalence and Early Onset in India

PD is more prevalent than commonly recognized and can occur at any age, although it is typically associated with older adults. In India, the onset of PD generally occurs around 51 years of age, which is about a decade earlier than in Western nations. This early onset affects individuals during their prime working years, leading to significant societal and economic burdens. A notable challenge is the lack of neurologists, particularly in rural areas, which often results in delayed diagnoses and suboptimal initial treatments. For instance, a study conducted in Gujarat reported a prevalence rate of 42.3 per 100,000 people, underscoring the substantial burden of PD.

Symptoms and Types of Onset

The symptoms of PD can significantly vary based on the age of onset:

• Younger Onset PD: Affects individuals under 50 years old and may present atypical symptoms such as resting tremors, cognitive challenges, and sleep issues, leading to potential misdiagnosis.
• Middle Age Onset PD: This is the most common form, typically emerging between 50 and 70 years, with early indicators including hand tremors, difficulties in handwriting, and changes in facial expressions.
• Late Onset PD: Diagnosed after the age of 70, this type tends to progress more slowly but often involves significant cognitive decline and dementia.

Advancing Treatments for Parkinson’s Disease

Managing PD in India presents challenges such as the affordability of medications and access to specialists. Nevertheless, recent advancements offer hope:

• Levodopa: This remains the cornerstone treatment, enhancing dopamine levels in the brain. However, its efficacy can diminish over time, leading to fluctuations in symptoms.
• Deep Brain Stimulation (DBS): This surgical procedure involves implanting electrodes in the brain to regulate abnormal electrical activity, significantly improving motor symptoms in advanced PD cases.
• Gene Therapy: An emerging field, gene therapy has the potential to alter genes, thus slowing or halting PD progression. Ongoing clinical trials may position India as a key player in this innovative research.

Conclusion

Addressing PD in India necessitates enhancing early diagnosis, improving access to treatment, and supporting ongoing research to explore innovative therapies. A deeper understanding of PD and its effects on younger populations calls for targeted strategies to manage and mitigate the disease's impact on both individuals and society.
