    Hyperthyroidism can cause irreversible chorea, a movement disorder, even after the endocrine condition resolves. This case highlights a rare, persistent neurological complication of thyrotoxicosis.

    Area of Science:

    • Neurology
    • Endocrinology
    • Movement Disorders

    Background:

    • Thyrotoxicosis, a state of excess thyroid hormones, is known to cause various neurological symptoms.
    • Chorea is characterized by involuntary, irregular, and unpredictable movements.

    Observation:

    • A patient with a history of thyrotoxicosis spanning over 30 years presented with persistent choreic movements.
    • The choreic movements began during the period of thyrotoxicosis and continued long after the endocrine disorder was managed.

    Findings:

    • This case report provides the first evidence that hyperthyroidism-induced chorea can persist long-term.
    • The neurological deficit (chorea) may become irreversible, independent of the underlying endocrine imbalance.

    Implications:

    • This suggests a potential for permanent neurological damage from severe or prolonged thyrotoxicosis.
    • Further research is warranted to understand the mechanisms behind persistent chorea and explore potential treatments.
