The potential role of Marginal Structural Models (MSMs) in testing the effectiveness of antidepressants in the treatment of patients with major depression in everyday clinical practice.

Objectives: To better evaluate the effectiveness of antidepressant drugs in the treatment of major depression in clinical practice.

Methods: A simulation experiment was used to illustrate an application of marginal structural models (MSMs) via inverse probability of treatment weighting (IPTW) approach in the context of non-randomized data on N = 1,000 depressed subjects, initially subjected to "watchful waiting". In simulation we assumed that subjects with worse intermediate outcome have a higher probability of being subsequently assigned to antidepressant treatment while those who receive antidepressant treatment are more likely to reach remission and less likely to reach relapse state.

The Hypomania Checklist-32 and the Mood Disorder Questionnaire as screening tools--going beyond samples of purely mood-disordered patients.

Background: Bipolar disorders are often not recognized. Several screening tools have been developed, e.g.

The impact of homocysteine levels on cognition in euthymic bipolar patients: a cross-sectional study.

Objective: Bipolar disorder is associated with cognitive impairment. High homocysteine levels seem to have a negative impact on cognition in the elderly. The aim of the present study was to investigate the potential relationship of elevated homocysteine levels and cognitive impairment in bipolar patients.

Impact of cognitive-psychoeducational interventions in bipolar patients and their relatives.

Background: In recent years, several controlled studies could show that psychoeducational interventions have been effective for relapse prevention in bipolar disorders. We therefore established a cognitive-psychoeducational group intervention with 14 sessions providing information about the illness, early warning signs, cognitive and behavioural strategies for stress management and social rhythm. Additionally we offered a group intervention for the patients' relatives.

The safety and tolerability of atypical antipsychotics in bipolar disorder.

Atypical antipsychotics (aAPs), have become a first-line treatment option, both in schizophrenia and bipolar disorders. Almost all aAPs now have proven efficacy in acute mania, some also in bipolar depression and in maintenance treatment. This provides reliable data on their safety and tolerability in this particular group of patients.
