Abstract

A thyrotropin-releasing hormone (TRH) test with serum thyroid-stimulating hormone (TSH) assays was performed in 22 euthyroid stroke patients without thyroid disease and the results were compared with those in 17 age-matched euthyroid controls. Basal and maximum TSH levels after TRH injection were significantly lower in the stroke group without elevation of basal serum thyroid hormone levels. There was a tendency towards an inverse relationship between TSH levels and the degree of pareses of the extremities. The test was repeated in 7 stroke patients 3-4 months after the onset of stroke with essentially the same results. The abnormal TSH parameters in stroke patients seem to be the result of the brain lesion per se.
