Prolactin responses to thyrotropin-releasing hormone in multi-infarct dementia and senile dementia of the Alzheimer type.
The serum prolactin (PRL) responses to stimulation with thyrotropin-releasing hormone (TRH) (500 micrograms Protirelin) were compared in 14 patients with multi-infarct dementia (MID) and 10 patients with senile dementia of the Alzheimer type (SDAT). Between the MID and the SDAT patients, there were no statistically significant differences in the median serum PRL concentrations, median changes in serum PRL concentrations or median proportional changes in serum PRL concentrations. Further, the serum PRL responses did not correlate with the GBS scale scores (degrees of dementia) or the GBS subscale scores (clinical profiles, including motor functioning, emotional functioning and intellectual functioning). In conclusion, the study does not support the hypothesis that serum PRL responses to TRH stimulation are of diagnostic value in differentiating between MID and SDAT.
