This study is based on 20 healthy volunteers (10 males and 10 females). Between 675 and 1,225 mg lithium carbonate per day was applied for 10 days. EEG was recorded before (day 0) and after lithium intake (day 10) with 19 electrodes and quantified by spectrum analyses. Absolute power and coherence values, between adjacent electrodes and between electrodes(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)
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)
BACKGROUND Neuroimaging studies have demonstrated an association between lithium (Li) treatment and brain structure in human subjects. A crucial unresolved question is whether this association reflects direct neurochemical effects of Li or indirect effects secondary to treatment or prevention of episodes of bipolar disorder (BD). METHOD To address this(More)
Clinical research centers in Aarhus, Berlin, Hamilton and Vienna collected mortality data for 827 manic-depressive and schizoaffective patients given lithium treatment for more than 6 months. The average duration of the treatment was 81 months and the total time on lithium 5600 patient-years. For each patient, the mortality risk was calculated by entering(More)
This article reviews current literature on the clinical efficacy of carbamazepine (CBZ) administration in schizophrenic and schizoaffective psychoses. With respect to the use of CBZ in cases of aggression, overactivity and other behavioral dyscontrol syndromes, only a few, mainly open, studies have been conducted. Attention to the efficacy of CBZ in(More)
We have previously shown that the mortality of patients with recurrent affective disorders in long-term lithium treatment is not higher than that of the general population. In the present study on 471 patients from Denmark and Germany, we examined mortality during the initial year of lithium treatment and during later lithium treatment. During initial(More)
For more than 30 years, lithium has been the drug of choice for the treatment of bipolar disorder. However, it has numerous adverse effects, a relatively slow onset of action, many common drug-drug interactions, and a narrow therapeutic index. Because of these problems, researchers looked for alternative and/or adjunctive treatments in bipolar disorder,(More)
PURPOSE Two common approaches to identify subgroups of patients with bipolar disorder are clustering methodology (mixture analysis) based on the age of onset, and a birth cohort analysis. This study investigates if a birth cohort effect will influence the results of clustering on the age of onset, using a large, international database. METHODS The(More)
