Seizures in thyrotoxicosis.

B Jabbari, A D Huott

    Epilepsia
    |February 1, 1980

    Summary
    This summary is machine-generated.

    Thyrotoxic seizures, a type of convulsive encephalopathy, can be the first sign of thyroid dysfunction. These seizures are likely caused by thyroid hormones directly affecting brain tissue, resolving once thyroid levels normalize.

    Area of Science:

    • Neurology
    • Endocrinology

    Background:

    • Thyroid dysfunction can manifest with neurological symptoms.
    • The relationship between thyrotoxicosis and seizures requires further elucidation.

    Observation:

    • Three patients with thyrotoxicosis presented with new-onset convulsive encephalopathy.
    • Patients experienced seizures only during active thyroid dysfunction.
    • Electroencephalograms indicated cerebral hyperexcitability, which normalized post-treatment.

    Findings:

    • Thyrotoxic seizures are not rare and can be focal or generalized.
    • Seizures presented as the initial symptom in these cases.
    • Absence of electrolyte imbalance or hypoglycemia suggests direct hormonal effects.

    Implications:

    • Thyrotoxicosis should be considered in patients with unexplained seizures.
    • Direct effects of thyroid hormones on the brain may cause seizures.
    • Prompt management of thyroid dysfunction is crucial for seizure resolution.
