Dysarthria Associated with Hashimoto’s Disease in A Type 1 Diabetic Patient

We report a diabetic patient seen at our department, presenting with worsening dysarthria. The patient was a 25- year- old woman. On examination the patient had a palpable thyroid gland (grade 1b), and the Romberg test was mildly impaired. Her thyroid profile showed an increased level of TSH, and a decrease in the levels of free T3 and free T4-findings consistent with hypothyrodism. Serum levels of antithyroid antibodies (TG-Ab and TPO-Ab) were increased. Ultrasonographic appearance of the thyroid gland was diffuse and hypoechoic. A brain CT showed cerebellar atrophy. Inasmuch as the findings of the patient were consistent with Hashimoto’s disease and progressive non-familial adult onset cerebellar degeneration, L-thyroxine treatment was begun. Dysarthria was observed to resolve on follow-up visits following the maintenance of the L-thyroxine treatment.
