Background Parkinson's disease is a neurological condition that progresses over time and causes terrible socioeconomic consequences for affected people, their families, and society as a whole. It is linked to both motor and non-motor symptoms, which has a substantial negative impact on older people's quality of life. Methods This one-year hospital-based observational cross-sectional study was carried out in the K.R. Hospital's neurology and medicine departments from November 2022 to October 2023. The study covered all Parkinson's disease patients who visited the K.R. Hospital's medicine and neurology outpatient and inpatient departments. Both the clinical signs and symptoms and the demographic information were noted. Results Males outnumbered girls by a significant margin. The average age of the research participants was 63.87±6.52 years. A total of 100%, 70%, and 26.67% of the participants reported having cardinal, motor, and non-motor symptoms, respectively. Subjects with both motor and non-motor symptoms had higher mean ages than their counterparts, indicating a statistically significant difference. Conclusion The features of the PD patients included in this study closely resemble those of other populations in India and other developing countries. However, the paucity of research and data on Parkinson's disease highlights the need for additional study of this neurodegenerative illness to gain a deeper understanding of its clinical and epidemiological features in our area.
