Study
| Hypothesis or Background |
Individuals with melancholic major depression exhibit basal hypercortisolism and an attenuated ACTH response to exogenous corticotropin-releasing hormone (CRH) infusion.
|
| Sample Information | 63 adolescent offspring of mothers with major depression, bipolar illness, or no psychiatric illness |
|---|
| Method Detail | Given the greater incidence of depression in children of depressed parents, we examined the ACTH and cortisol responses to ovine CRH (oCRH) infusion in 63 adolescent offspring of mothers with major depression, bipolar illness, or no psychiatric illness. Psychiatric and observational assessments of these families had been conducted over the course of 10 years preceding this study |
| Method Keywords | dose administration; blood analysis |
| Result | We examined the children's responses to CRH in relation to maternal characteristics and family environment and found the following: (a) cortisol responses were negatively related to chronic family stress and (b) offspring of depressed mothers with an avoidant personality disorder showed an exaggerated ACTH response. In addition, adolescents in late puberty (Tanner 4 and 5) had lower ACTH and cortisol responses to oCRH infusion than those in early puberty. Further, offspring with early histories of mood problems, and those who developed major depressive disorder as young adults, did not exhibit basal hypercortisolism but did show an attenuated ACTH response to CRH. |
| Conclusions | Our results add to the growing body of literature showing the influence of maternal characteristics and environmental factors on hypothalamic-pituitary-adrenal axis patterns in children. |
