Transitory procaine-induced Parkinsonism.

F Gjerris

    Journal of Neurology, Neurosurgery, and Psychiatry
    |February 1, 1971

    Summary
    This summary is machine-generated.

    Procaine can cause reversible Parkinsonism, a condition mimicking Parkinson's disease. This case highlights successful treatment with l-dopa and trihexyphenidyl, suggesting dopamine system involvement.

    Area of Science:

    • Neuroscience
    • Pharmacology
    • Neurology

    Background:

    • Parkinsonism is a clinical syndrome characterized by tremor, rigidity, bradykinesia, and postural instability.
    • Drug-induced Parkinsonism is a common cause of secondary Parkinsonism, with various medications implicated.
    • Procaine, a local anesthetic, has been rarely associated with Parkinsonian symptoms.

    Purpose of the Study:

    • To report a case of prolonged procaine-induced Parkinsonism.
    • To describe the successful treatment of this condition.
    • To discuss the pathophysiological mechanisms underlying procaine-induced Parkinsonism.

    Main Methods:

    • Case report of a patient presenting with Parkinsonian symptoms after procaine exposure.
    • Clinical observation of symptom progression and response to treatment.

    Related Experiment Videos

  • Review of existing literature and theories on basal ganglia neurotransmitter systems.

    • Main Results:

    • The patient developed prolonged, yet reversible, Parkinsonian symptoms attributed to procaine.
    • Treatment with l-dopa and trihexyphenidyl (Artane-Sustets) resulted in significant symptom improvement.
    • The findings support a link between procaine and dopaminergic pathways in the basal ganglia.

    Conclusions:

    • Procaine can induce a reversible Parkinsonian syndrome.
    • L-dopa and trihexyphenidyl are effective treatments for procaine-induced Parkinsonism.
    • The pathophysiology likely involves disruption of basal ganglia neurotransmitter systems, particularly dopaminergic pathways.
