Emotion dysregulation and impulsivity as overlapping symptoms in adult Attention-Deficit/Hyperactivity Disorder and Borderline Personality Disorder: severity profiles and associations with childhood traumatization and personality functioning.

Background: Increased levels of emotion dysregulation and impulsive behavior are overlapping symptoms in adult Attention-Deficit/Hyperactivity Disorder (aADHD) and Borderline Personality Disorder (BPD), both symptom domains reflecting on inhibitory control, although from different angles. Our aims were to describe their differences in the above conditions, investigate their associations with childhood traumatization, and to explore the potential mediation of emotion dysregulation and impulsivity between childhood traumas and personality functioning.

Methods: Young adults between 18 and 36 years diagnosed with aADHD (n = 100) and BPD (n = 63) were investigated with structured clinical interviews, while age-matched healthy controls (n = 100) were screened for psychiatric disorders.

Hungarian validation of the Buss-Perry Aggression Questionnaire-Is the short form more adequate?

Objective: We aim to provide a publicly available Hungarian version of the BPAQ; compare the BPAQ factors to other personality traits; and compare both the original BPAQ factor structure provided by Buss and Perry (J. Pers. Soc.

Association of purinergic receptor P2RX7 gene polymorphisms with depression symptoms.

Introduction: The activation of the ATP-gated P2RX7 (purinergic receptor P2X, ligand-gated ion channel, 7) produces microglial activation, a process which has been demonstrated in depression, bipolar disorder, and schizophrenia. Emerging data over the last years highlighted the importance of P2X7 cation channel as a potential drug target for these central nervous system disorders. The Gln460Arg (rs2230912) polymorphism of the P2RX7 gene has been widely studied in mood disorders, however the results are still controversial.

[Association between mood characteristics and polymorphisms of glial cell line-derived neurotrophic factor (GNDF) in patients with depression].

Glial cell line-derived neurotrophic factor (GNDF) plays an important role in the development and synaptic plasticity of dopaminergic neurons, thus it could be an important therapeutic factor in Parkinson's disease. Results from candidate gene studies of GDNF in psychiatric disorders are contradictory. Moreover, the possible association between GDNF polymorphisms and major- or bipolar depression has not been studied to date.

Associations between depression severity and purinergic receptor P2RX7 gene polymorphisms.

Background: Major depressive disorder (MDD) and bipolar disorder (BPD) have significant genetic predisposition. The P2RX7 gene (coding for P2X7 purinergic receptor) has been suggested as a susceptibility gene for both MDD and BPD. In the current study the genetic effects of rs2230912 (Gln460Arg) and rs1653625 (located in the 3' untranslated region of the P2RX7 gene) were explored in mood disorders.

Peripheral vascular endothelial growth factor level is associated with antidepressant treatment response: results of a preliminary study.

Background: Recent investigations have revealed multiple actions of vascular endothelial growth factor (VEGF) in the nervous system. The role of VEGF in the molecular background of mood disorders has also been proposed. In this study we were interested in investigating a possible association between VEGF levels and treatment response in patients with a current episode of major depression (MDE).

Investigation of circulating endothelial progenitor cells and angiogenic and inflammatory cytokines during recovery from an episode of major depression.

Background: Epidemiological studies strongly suggest a bidirectional positive relationship between mood and cardiovascular disorders (CVD). Reduced numbers of circulating endothelial progenitor cells (cEPCs) are associated with elevated risks of CVD. Previously we demonstrated that patients with a current episode of major depression (MDE) have a decreased number of cEPCs.

Association between hypnotizability and the catechol-O-methyltransferase (COMT) polymorphism.

Previous studies implicate involvement of dopaminergic systems in hypnotizability and report association with the COMT Val(158)Met single nucleotide polymorphism (SNP, rs4680) demonstrating the Val/Met heterozygotes as the most hypnotizable group using the Stanford Hypnotic Susceptibility Scale. This study replicates that association using an independent sample of 127 healthy Hungarian young adults and the Waterloo-Stanford Group C Scale of Hypnotic Susceptibility. Significant association (p = .

[Validation of a new mood questionnaire on healthy sample].

Depression is a frequent, wide spectrum disease causing substantial suffering. Quantitative tools for measuring depression are rather important both at the clinical and non-clinical state. BDI (Beck Depression Inventory) the HADS (Hospital Anxiety and Depression Scale) and the BHS (Beck Hopelessness Scale) are used both in clinical practice and research.

Association between depression and the Gln460Arg polymorphism of P2RX7 gene: a dimensional approach.

The P2RX7 gene (coding for P2X7 purinergic receptor) has been suggested as a novel candidate gene for major depressive disorder (MDD) and bipolar disorder (BPD). The proposed risk allele (G-allele) of the rs2230912 polymorphism results in an amino acid change at the 460th position, marking this genetic variation a possibly functional one. Here we present a case-control analysis of 171 patients diagnosed with MDD or BPD and 178 controls, as well as a dimensional approach using the Hospital Anxiety and Depression Scale (HADS) for studying the Gln460Arg polymorphism of the P2RX7 gene as a genetic risk factor in depression.
