Brief Summary

Bipolar disorder (BPD) is often misdiagnosed as unipolar depression. This leads to inadequate treatment and can have negative impact on the course of the disease. There is now preliminary evidence that patients with unipolar and bipolar depression as well as healthy individuals with a heightened risk of BPD can be distinguished from each other based on their brain activity patterns and functional connectivity during resting state. However, the impact of pharmacological treatment on these functional brain measures have not yet been clarified. For common antidepressants it has been shown that they seem to normalise aberrant brain activity patterns and functional connectivity. The problem is that some antidepressants can induce mania or accelerate pathological cycling in depressive patients with unrecognised BPD. Therefore, pharmacological drugs with mood-stabilising properties such as quetiapine are more and more prescribed. Although the effectiveness and tolerability have been proven, the neuronal effects of these adjunctive treatments are not clear. The aim of the study is thus to investigate the impact of quetiapine on measures of brain activity in depressive patients with a heightened risk of BPD. Moreover, the investigators want to examine whether the investigators can distinguish depressive patients with a heightened risk of BPD from depressive patients without a heightened risk of BPD using neuroimaging techniques, and whether these measures can predict the course of the disease.

Outcome Measures

Primary Outcomes (5)

  • BOLD signal during a combined inhibition-reward-task

    At baseline (day 0) the risk-group and control-group will be compared on BOLD signal (and behavioural data) during a combined inhibition-reward-task (neuronal correlate of cognitive control) (fMRI). These measures will be obtained once again at visit 4 (day 56) in the risk-group to evaluate the impact of quetiapine (i.e. change from baseline measure).

    Baseline (Day 0)

  • Functional connectivity in the default mode network during resting state (rstfMRI)

    At baseline (day 0) the risk-group and control-group will be compared on functional connectivity in the default mode network during resting state (rstfMRI).

    Baseline (Day 0)

  • Structural differences in brain anatomy (MRI)

    At baseline (day 0) the risk-group and control-group will be compared on structural differences in brain anatomy (MRI).

    Baseline (Day 0)

  • Structural integrity of nerve fibres (DTI)

    At baseline (day 0) the risk-group and control-group will be compared on structural integrity of nerve fibres (DTI).

    Baseline (Day 0)

  • Effect of quetiapine on brain measures

    After the quetiapine/ placebo intervention the risk-group will be compared whether there are changes from baseline in outcome measures 1 to 4.

    Visit 4 (Day 56)

Secondary Outcomes (3)

  • Plasma levels of quetiapine

    Visit 4 (Day 56)

  • Change over time in affect and psychopathology

    Baseline (Day 0), Visit 4 (Day 56), Follow-up (after 1 year)

  • Personality

    Baseline (Day 0)

Study Arms (3)

Quetiapine

EXPERIMENTAL

18 patients of the risk-group will receive quetiapine (Seroquel Prolong (c)) for 8 weeks in adjunction to their antidepressant standard therapy. Group allocation is randomised and double-blind. Dosages: 50mg (day 1-3), 100mg (day 4-6) and 150mg (from day 7 onwards). Administration: Quetiapine will be given once daily before bedtime, not together with a meal and swallowed as a whole.

Drug: Quetiapine

Placebo

PLACEBO COMPARATOR

18 patients of the risk-group will receive placebo for 8 weeks in adjunction to their antidepressant standard therapy. Group allocation is randomised and double-blind. The placebo does not contain any psychoactive substance.

Drug: Placebo

Control-group

NO INTERVENTION

18 depressive patients without a heightened risk for BPD will not receive any medication apart from their standard antidepressant therapy (control-group).
