Age and the dexamethasone suppression test in depression.
The authors examined the effects of age on plasma cortisol concentrations of 81 depressed men after dexamethasone administration. Dexamethasone nonsuppression was significantly more frequent in patients older than age 55 than those younger. Similarly, older patients had significantly higher postdexamethasone cortisol concentrations than younger patients at all time points sampled. These differences could not be attributed to severity or to the prevalence of psychosis in older and younger depressed patients.
