  • How does PD differ from Alzheimer’s or other brain diseases?
    MedlinePlusMay 2026

    Parkinson's disease starts with movement problems, while Alzheimer's mainly affects memory and thinking first. Both can eventually cause thinking problems, but PD begins differently and involves more movement issues.

  • Why do I have trouble moving and thinking clearly?
    MedlinePlusMay 2026

    Parkinson's damages parts of your brain that control movement and thinking. This is why you may feel stiff, move slowly, and have trouble with memory or focus.

  • Will my symptoms get worse over time?
    MedlinePlusMay 2026

    Yes, Parkinson's symptoms typically get worse over time, though the speed varies from person to person. Treatment can help manage symptoms and slow some changes.

  • Can you explain why my muscles feel stiff?
    MedlinePlusMay 2026

    In Parkinson's, the brain doesn't send the right signals to your muscles, making them tight and hard to move. This stiffness is one of the main symptoms of the disease.
