Hypothyroidism is a common endocrine disorder with characteristic clinical symptoms and signs. Typical symptoms of hypothyroidism are lethargy, cold intolerance, slowing of intellectual and motor activity, decreased appetite, weight gain, and dry skin. A 39-year-old female presented to the clinic with dysarthria as the chief symptom. Subsequent questions revealed that other symptoms were confined to the otolaryngeal region, which were episodes of mild dysphonia, dysphagia, sleep apnea, and snoring. Laboratory data revealed marked hypothyroidism and positive tests for antithyroglobulin and antimicrosomal antibodies. After administration of thyroxin, the dysarthria and the other symptoms rapidly disappeared. Dysarthria may be the presenting symptom of hypothyroidism and can be resolved after hormone replacement therapy.
