Dexamethasone Suppression Test in Cluster Headache

Authors


Abstract

SYNOPSIS

The dexamethasone suppression test was performed on eleven patients with cluster headache. Interest in such investigation of the hypothalamo-pituitary-adrenal axis in cluster headache arose from both a certain analogy with manic-depressive disorders and recent data on abnormal patterns of cortisol secretion in cluster headache. Investigation results were normal in all patients, showing that the hypothalamo-pituitary-adrenal dysfunction reported in depressions is not a biological feature of cluster headache.
