BACKGROUND Prediction of treatment outcome has important clinical consequences. Personality factors have rarely been tested as predictors of acute outcome. Personality, demographic and illness-related characteristics were assessed at baseline for prediction of outcome of treatment in depressed out-patients. METHODS One hundred and ninety-three patients(More)
It has frequently been demonstrated that acute tryptophan depletion (ATD) induces a transient depressed mood in some patients who are in remission from depression. However, the effects of ATD on cognitive processes in remitted depressed patients have not been investigated. The aim of the present study was to investigate the effects of different extents of(More)
BACKGROUND Acute tryptophan depletion transiently induces symptoms in those with remitted depression. The behavioural specificity is uncertain, however. Recently, symptom provocation studies have become controversial, particularly in the USA. AIMS To assess the specificity of acute tryptophan depletion. To investigate systematically the subjective(More)
In a double-blind study the selective monoamine oxidase-A inhibitor brofaromine was compared with the classical MAOI tranylcypromine in 39 patients with major depression resistant to treatment with tricyclic antidepressants. Concerning efficacy no significant differences were found. Ten out of 22 patients responded to brofaromine and 5 out of 17 patients to(More)
In 16 depression clinics in hospitals and outpatient facilities in the Netherlands, a study was performed to evaluate and compare the efficacy and tolerability of citalopram and fluvoxamine and to determine the difference in the incidence of gastrointestinal side-effects. A total of 217 patients with a depressive disorder (DSM-III-R criteria) and a score of(More)
Thirty-three patients with depression treated with 225 mg venlafaxine were genotyped for the polymorphic enzyme, debrisoquine 4-hydroxylase (CYP2D6). The relationship between drug and metabolite levels and between genotype and clinical response were investigated. Although the number of responders in this study is insufficient for definite conclusions to be(More)
BACKGROUND It has frequently been demonstrated that experimental lowering of serotonin (5-HT) neurotransmission by acute tryptophan depletion (ATD) induces a transient depressed mood in 50-60% of patients treated with a selective serotonin reuptake inhibitor (SSRI) who are in remission from depression. In unmedicated depressed patients, ATD has no immediate(More)
OBJECTIVES The efficacy and tolerability of sodium valproate 2 x 240 mg compared to placebo were investigated in aggressive behavior in dementia. DESIGN A randomized, placebo controlled, double-blind cross-over design. The trial included a baseline period (one week); a placebo period (three weeks); a wash-out period with placebo (one week); and a(More)
BACKGROUND Depression is a major risk factor for cardiovascular disease. An important risk factor for cardiovascular disease, low heart rate variability, often has been found in depressed patients and has been associated with impulsivity. The present study investigated whether experimental lowering of serotonin would decrease heart rate variability and(More)
It has been well documented that acute tryptophan depletion (ATD) induces symptoms in remitted depressed patients treated with an SSRI. ATD also has effects on cognition, both in patients and in healthy samples. The exact nature of ATD-induced cognitive changes in depression remains unclear. It is also unclear whether cognitive effects can be induced(More)
