    Last Updated: October 25, 2023

    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]
