Understanding Parkinson’s Disease: Causes, Progression, and Outlook

Parkinson’s disease is a gradual neurodegenerative condition that impacts brain function and nerve health. Although not directly fatal, it shortens lifespan over time. The core cause involves a decline in dopamine-producing cells, essential for coordinated movement. The specific reasons for dopamine loss remain uncertain; genetic factors and environmental exposures, like pesticides, are suspected contributors. Men are approximately 50% more vulnerable than women. Recognizable symptoms include tremors, balance issues, spasms, and memory decline. The disease advances through five stages over 15-20 years, from mild symptoms to severe disability. While no cure exists, medications help slow progress. Early detection improves quality of life and lifespan. Those diagnosed in early stages can manage symptoms effectively, extending longevity. The average survival post-diagnosis is around 16 years, emphasizing the importance of prompt medical attention for any signs of the disease.
