The effects of Parkinson’s disease on the brain cause both motor (i.e., movement-associated) and non-motor symptoms. The symptoms are subtle at first, but progressively worsen over time.[1]
Common motor symptoms of Parkinson’s disease include the following:
- Tremors, which can occur in different parts of the body including the head, arms, legs, and jaw
- Bradykinesia (slowness of movement)
- Changes in gait
- Impaired balance and coordination
- Muscle stiffness
(These motor symptoms make patients prone to serious falls and injuries.)
People with Parkinson’s disease may experience any of the following non-motor symptoms:
- Depression
- Fatigue and excessive daytime sleepiness
- Anxiety
- Cognitive decline[2] / Dementia
- Constipation or urinary problems
- Skin problems[3]
