Overview

abstract

  • Morning plasma cortisol response to the 1 mg dexamethasone suppression test along with cortisol levels in blood, cerebrospinal fluid (CSF), and urine were measured in hospitalized male and female patients with primary major depressive disorder who reported hypersomnia (n = 23), or increase in appetite (n = 22). Comparisons were drawn to cortisol levels in patients with primary major depressive disorder who did not report hypersomnia or appetite increase (n = 23) and to normal controls (n = 23), all age- and sex-matched. Depressives with hypersomnia or increased appetite showed higher than normal 24-h urinary free cortisol concentrations. Depressed patients without hypersomnia or appetite increase had in addition to elevated free urinary cortisol concentrations higher than normal morning plasma cortisol levels before and after dexamethasone administration and a higher incidence of cortisol non-suppression after dexamethasone compared to normal subjects. The findings provide preliminary evidence that HPA activation in depression is diminished in the presence of hypersomnia and/or an increased appetite. Studies of the hypothalamic-pituitary-adrenal axis may be useful for differentiating subtypes of depression characterized by hypersomnia or enhanced appetite.
