[Effect of thyroliberin treatment on the thyrotropin and prolactin levels in patients with amyotrophic lateral sclerosis].

The blood serum TSH and PRL levels were studied in 12 ALS patients after TRH stimulation. The TSH test was repeated after 4-weeks TRH treatment. The results were compared with the data obtained in the control group. It was shown that after TRH stimulation the TSH responses did not reveal greater abnormalities, but PRL responses were significantly diminished. The results could confirm our previous observations concerning the dysregulation of dopamine metabolism in ALS patients.
