Seasonal variations in the dexamethasone suppression test.
One hundred and fifty-six patients from Epsom (U.K.) and Brussels, all suffering from major depressive disorder, were tested on the dexamethasone suppression test. Post-dexamethasone cortisol concentration in the plasma was found to be much lower in the winter months (November to February) than in the rest of the year.
