What this trial studies

This observational study aims to assess the prevalence and characteristics of Restless Legs Syndrome (RLS) in Thai patients diagnosed with Parkinson's Disease (PD). It will involve screening participants aged 18 to 80 years who meet specific diagnostic criteria for PD. The study seeks to identify the prevalence of RLS among this population, which has been under-researched in Thailand, and to explore the potential relationship between RLS and PD. By gathering data on this condition, the study hopes to improve understanding and management of RLS in patients with PD.

Who should consider this trial

Good fit: Ideal candidates for this study are Thai patients aged 18 to 80 years who have been diagnosed with Parkinson's Disease according to established criteria.

Not a fit: Patients with atypical or secondary parkinsonism, or those with cognitive impairments or secondary causes of RLS, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better recognition and management of Restless Legs Syndrome in patients with Parkinson's Disease, ultimately improving their quality of life.

How similar studies have performed: While there have been studies on RLS in Parkinson's Disease globally, this specific focus on the Thai population is novel and has not been extensively explored.
