Parkinson's disease

Parkinson's disease is a progressive neurological disorder that affects movement control, typically starting with subtle tremors in one hand. It occurs due to the degeneration of dopamine-producing neurons in the brain, primarily in an area called the substantia nigra. Common symptoms include muscle rigidity, slow movements (bradykinesia), balance issues, and speech changes. Though the exact cause is unclear, genetic and environmental factors may contribute to its development. Parkinson's is most common in older adults and worsens over time, though medications and therapies can help manage symptoms. Research continues into finding more effective treatments and, ultimately, a cure.
