Electrodermal Responding in Hyperthyroid Patients.

The effects of hyperthyroidism on electrodermal habituation and responsiveness were examined in 43 hyperthyroid patients who were divided in two groups (medicated and unmedicated). In a comparison of 43 hyperthyroid and 43 normal controls; among patients with hyperthyroidism a great number of nonresponders were found. The distributions of SCR in habituation series in both group were almost the same but hyperthyroid patients were in slower habituation status than controls. These findings suggest that electrodermal nonresponsiveness or slow habituation in hyperthyroid patients might be considered as a function due to changes in the metabolism of biogenic mines in the central nervous system.
