Parkinson's disease is a progressive neurodegenerative disorder that primarily affects movement. It is named after Dr. James Parkinson, who first described the symptoms in 1817. The condition is characterized by the degeneration of dopamine-producing neurons in a specific region of the brain called the substantia nigra.
Parkinson's disease include:
- Tremors: Involuntary shaking or trembling, often starting in the hands.
- Bradykinesia: Slowness of movement, making everyday tasks more difficult.
- Muscle Rigidity: Stiffness of the limbs and joints, affecting flexibility and range of motion.
- Postural Instability: Difficulty maintaining balance and an increased risk of falls.
