Parkinson's disease is a progressive movement disorder resulting from the gradual loss of dopamine-producing cells in the substantia nigra region of the brain.
While Parkinson's is a chronic condition, modern neurological pharmacotherapy and multidisciplinary rehabilitation enable patients to remain active and independent for decades.
The Four Cardinal Symptoms
- Tremor at Rest: Involuntary rhythmic shaking, often starting in one hand or thumb ("pill-rolling" tremor), occurring when muscles are relaxed.
- Bradykinesia (Slowness of Movement): Difficulty initiating movements, reduced arm swing when walking, and slower completion of daily tasks like buttoning a shirt.
- Muscle Rigidity: Stiffness and resistance in limbs and trunk during movement, leading to muscle cramps.
- Postural Instability: Impaired balance and changes in walking gait, increasing fall risks.
Comprehensive Treatment Strategy
Treatment combines levodopa and dopamine agonist medications to restore brain chemical balance, combined with targeted gait and speech therapy exercises.
