N2  - OBJECTIVE: There is evidence that suicidal behavior, among others, is an abnormal response to stress caused by a dysfunction in the activity of hypothalamus-pituitary-adrenal axis, and that cortisol levels are low in a considerable number of people attempting suicide. In this study, we aimed to search for associations of plasma cortisol levels with the clinical characteristics of a group of psychiatric suicide attempters. <br><br>METHOD: The cortisol was measured in the morning in 200 psychiatric patients hospitalized after a suicide attempt, with diagnoses of major depressive disorder, bipolar disorder, psychosis, and personality/adjustment disorder, and compared to the levels of 138 healthy controls. Comparisons were also made for diagnostic subgroups and across diagnoses, with regard to depressive symptomatology, mode of attempt, suicide intent, number of attempts, and age. <br><br>RESULTS: Cortisol levels were significantly lower for the whole group of attempters compared to controls. Furthermore, low cortisol levels characterized attempters with personality/adjustment disorder, higher depressive symptomatology, low suicide intent, non-violent attempt mode, repeated attempts, and of younger age. <br><br>CONCLUSIONS: Certain clinical characteristics were identified in attempters with low cortisol levels. In previous studies, low cortisol levels have been associated with impairments in cognitive control, decision-making, and emotional processing that may lead, in the presence of stressors, to suicidal behavior, frequently with non-fatal outcome. Adding plasma cortisol levels to demographic and psychopathological data may help in identifying a subpopulation of attempters with neurocognitive deficits linked to dysfunction of Hypothalamic-Pituitary-Adrenal-axis activity, with implications for treatment.<br><br>© 2018 S.
