Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether outcome following antidepressant treatment can be used as a tool to evaluate endo-phenotypes for depression.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The research in depression has for some years focused at the identification of endo-phenotypes. Endo-phenotypes are heritable biological or psychological markers, which are more commonly found in patients and their healthy relatives than in the general population.

Recent studies point at disturbed regulation of the hypothalamic-pituitary-adrenocortical (HPA) system as a possible endo-phenotype for depression.

The hypothesis of AGENDA are that endo-phenotypes are affected by treatment with antidepressants in healthy first degree relatives.

AGENDA is a four week randomized, placebo-controlled, double-blind trial in which first degree relatives of patients with the diagnosis of depression are randomised in to two groups, which are treated with either placebo or antidepressant medicine (Cipralex). We expect to include 80 healthy subjects, with the predisposition for depression, since one of their parents or siblings recently was treated for depression.

The subjects will be examined before and after four weeks of treatment by a thorough interview concerning psychiatric symptoms (SCAN), including depressive symptoms, personality, perceived stress and cognitive function. The effect of antidepressant on stress is measured with saliva-cortisol and by the response to the combined dexamethasone corticotropin-releasing (CRH) hormone test. Additionally, MR and PET scans of the 5-HT4 receptor function will be conducted before and after 4 weeks of treatment.
