Parkinson's Disease - Causes
Parkinson's Disease (PD) is a progressive nervous system disorder that affects movement. Symptoms begin gradually, sometimes starting with a barely noticeable tremor in just one hand. Tremors are common, but the disorder also commonly causes stiffness or slowing of movement, walking disturbances and postural abnormalities.
In the early stages of PD, the face may show little or no expression, arms may not swing when walking, speech may become soft or slurred. Parkinson's Disease symptoms worsen over time.
Although PD cannot be cured, medications might significantly improve symptoms. Occasionally, the neurologist may suggest surgery to regulate certain regions of the brain and improve symptoms.
