Several studies have linked 5-HT1A C1019G and BDNF G196A (Val66Met) gene polymorphisms to major depressive disorder (MDD) and the actions of antidepressants. We attempt to show that the interaction between 5-HT1A and BDNF polymorphism predicts the risk of treatment-resistant depression. The sample consists of 119 patients with treatment-resistant MDD and(More)
The 5HT2A receptor gene (HTR2A) polymorphisms rs7997012 and rs6311 have in some earlier studies been associated with serotonin selective reuptake inhibitor (SSRI) treatment response in major depressive disorder (MDD), but the findings are inconsistent. The aim of the present study was to test for an association between two HTR2A polymorphisms (rs7997012 and(More)
The aim of the present study was to examine an association of brain-derived neurotrophic factor (BDNF) polymorphisms G196A and C270T and the response to electroconvulsive therapy (ECT) in major depressive disorder (MDD). The study group consisted of 119 patients consecutively admitted for ECT in the Department of Psychiatry, Tampere University Hospital. All(More)
Alterations in dopamine levels and dopamine receptors in brain are suggested to be associated with treatment response in electroconvulsive therapy (ECT). Dopamine 2 receptor gene (DRD2) polymorphism C957T (rs6277) and cathechol-o-methyltransferase (COMT) polymorphism Val158Met (rs4680) interaction was studied in 118 patients suffering from major depressive(More)
Several lines of evidence suggest that catechol-O-methyltransferase (COMT) may be associated with treatment response in depression. We conducted a study on 119 patients with treatment-refractory depression admitted consecutively for electroconvulsive therapy (ECT). The COMT high/high genotype leads to a higher enzyme activity and thus lowers dopaminergic(More)
The angiotensin I-converting enzyme gene (ACE) has been repeatedly suggested as a major gene affecting affective disorders and their treatment, but the study results have been ambiguous so far. The primary purpose of this study was to compare the effects of the ACE genotype distributions and treatment response to electroconvulsive therapy (ECT) in patients(More)
INTRODUCTION It is difficult to treat patients who, in addition to having severe anorexia nervosa, also have severe symptoms of major depressive disorder and a tendency for impulsive acting out behaviour. Our case report considers the feasibility of maintenance electroconvulsive therapy in such complicated cases. CASE PRESENTATION This is a case report of(More)
The association of two tryptophan hydroxylase 2 (TPH2) polymorphisms and treatment response in electroconvulsive therapy (ECT) and the risk of depression was studied. The patient sample consisted of 119 subjects with treatment-resistant major depressive disorder who were treated with ECT. Treatment response was assessed by the Montgomery and Asberg(More)
We studied the association between RGS4 (rs951436) polymorphism and treatment response in electroconvulsive therapy (ECT) as well as risk of treatment-resistant depression. The study sample consisted of 119 patients with major depressive disorder (MDD) and 384 healthy control subjects. RGS4 polymorphism was not associated with treatment response in ECT or(More)
