    Summary
    This summary is machine-generated.

    Baclofen significantly worsened Parkinsonism symptoms in patients with long-term levodopa syndrome. While it did not improve choreoathetosis, baclofen showed benefits for off-period dystonia but caused severe side effects.

    Area of Science:

    • Neurology
    • Movement Disorders
    • Pharmacology

    Background:

    • Levodopa is a primary treatment for Parkinson's disease.
    • Long-term levodopa use can lead to motor complications.
    • Parkinsonism encompasses a range of motor symptoms associated with Parkinson's disease.

    Purpose of the Study:

    • To evaluate the efficacy and safety of baclofen in patients with Parkinsonism and long-term levodopa syndrome.
    • To assess baclofen's impact on specific motor complications like choreoathetosis and off-period dystonia.

    Main Methods:

    • A controlled trial involving 12 patients with Parkinsonism and long-term levodopa syndrome.
    • Administration of baclofen with a mean daily dose of 45 mg.
    • Assessment of disability and specific motor symptoms including choreoathetosis and off-period dystonia.

    Main Results:

    • Baclofen significantly increased disability associated with Parkinsonism.
    • No improvement was observed in peak-dose choreoathetosis.
    • Benefit was noted in all four patients experiencing off-period dystonia.

    Conclusions:

    • Baclofen is not recommended for Parkinsonism in patients with long-term levodopa syndrome due to increased disability.
    • Baclofen may offer benefits for off-period dystonia but carries a risk of severe adverse effects.
    • Adverse events such as hallucinations, vomiting, and dizziness were common and severe.
