SYNOPSIS

After neuropsychological evaluation, we administered the dexamethasone suppression test to eleven patientssuffering from muscle-contraction headache and to thirteen patients affected by migraine, in order to verify a possiblecorrelation between a chronic pain such as headache and a cortisolemic response to dexamethasone. None of themappeared to be suffering from depressive syndrome; all patients were DST suppressors. These data suggest that thedexamethasone suppression test does not correlate with chronic pain, but with depression, consistent with the highspecificity of this marker test for depression.
