The mortality of patients suffering from affective disorders is much higher than that of the general population; this excess is due to both suicides and cardiovascular disease. During long-term lithium treatment, the overall mortality has not been found to differ significantly from that of the general population but the question remains whether this(More)
Bipolar disorder (BD) is a genetically complex mental illness characterized by severe oscillations of mood and behaviour. Genome-wide association studies (GWAS) have identified several risk loci that together account for a small portion of the heritability. To identify additional risk loci, we performed a two-stage meta-analysis of >9 million genetic(More)
The prophylactic efficacy of carbamazepine slow release (CBZ) at ke different blood levels and lithium carbonate slow release (LI) was compared in a retrospective/prospective, randomized, 2-year open trial. 84 patients with a DSM-III-R diagnosis of recurrent affective disorder who had no prophylactic medication in the 2 years preceding the trial (no LI(More)
BACKGROUND Lithium is a first-line treatment in bipolar disorder, but individual response is variable. Previous studies have suggested that lithium response is a heritable trait. However, no genetic markers of treatment response have been reproducibly identified. METHODS Here, we report the results of a genome-wide association study of lithium response in(More)
N-methyl D-aspartate (NMDA)-antagonists decrease neurotoxicity by inhibiting Ca2+ influx which is of interest for the treatment of acute cerebrovascular insults and chronic neurodegenerative disorders. Currently, there is no surrogate marker for quantification of NMDA-receptor-mediated drug effects, which hampers dose-finding clinical studies. As prolactin(More)
BACKGROUND Because randomized clinical trials in bipolar disorder include restricted study populations, the possibilities for generalizing to real-world bipolar patients are limited. Naturalistic long-term data can add valuable information about the diversity of treatment and outcome in bipolar disorder. METHOD After discharge from a psychiatric community(More)
200 first admissions with functional psychoses were interviewed with PSE and rated simultaneously according to different diagnostic criteria (ICD-9, RDC, DSM-III, St. Louis, Taylor, Vienna Research Criteria). At follow-up 7 years later 186 patients could be traced and a course diagnosis was applied to each patient. Temporal stability of diagnostic criteria(More)
The perplexity psychiatry is faced with when approaching the problem of 'schizo-affective disorders' is the result of two characteristic features of human psychology: The first consists in the tendency to pick up quickly attractively formulated terms and to prefer them to others designating the same facts. The second psychological trend referred to concerns(More)
A multicenter randomized 4-week interindividual double-blind study was carried out in 58 hospitalized patients with major depressive disorder (DSM III 296.23, 296.22, 296.33, 296.32, 296.53 and 296.52) to test the dose-effect relationship of three different doses of the new cAMP-phosphodiesterase inhibitor rolipram: 3 x 0.25 mg, 3 x 0.50 mg and 3 x 1.00 mg(More)
