Understanding Parkinson's Disease: Causes, Symptoms, Stages, and Prognosis

Parkinson's disease is a progressive neurological disorder that impacts movement, coordination, and mental function. While it isn't directly fatal, it can shorten lifespan due to complications. The core issue involves a decline in dopamine-producing brain cells, which hampers normal motor activity. The exact cause remains uncertain, but theories point to genetic factors and environmental exposures like pesticides. Men are also more susceptible than women. Symptoms develop gradually, including tremors, balance problems, and memory issues, progressing through five stages over 15-20 years. Although no cure exists, treatments can help manage symptoms and slow progression, especially when diagnosed early. Typically affecting those over 60, early detection is crucial for improving life expectancy. Regular check-ups and medical interventions can extend quality of life.
