Glycogen synthase kinase-3beta (GSK-3beta) has been implicated in the pathogenesis of major psychoses. In this paper, the T-50C polymorphism of the GSK-3beta gene has been studied in patients with schizophrenia (n=432), patients with bipolar disorder (n=416) and in a healthy control group (n=408). Consensus diagnosis by at least two psychiatrists was made(More)
OBJECTIVES Polymorphisms in BDNF gene has been proposed, as susceptibility loci for stress-related psychiatric disorders. Several lines of molecular and biochemical evidence point to the role of BDNF in anorexia nervosa (AN). Personality traits may constitute the intermediate phenotypes between genes and vulnerability to AN. METHODS BDNF Val66Met and(More)
Brain-derived neurotrophic factor (BDNF) has been implicated in the pathogenesis of schizophrenia and bipolar disorder. A functional polymorphism Val66Met of BDNF gene was studied in patients with schizophrenia (n=336), bipolar affective disorder (n=352) and healthy controls (n=375). Consensus diagnosis by at least two psychiatrists, according to DSM-IV and(More)
Schizophrenia has been associated with a large range of autoimmune diseases, with a history of any autoimmune disease being associated with a 45% increase in risk for the illness. The inflammatory system may trigger or modulate the course of schizophrenia through complex mechanisms influencing neurodevelopment, neuroplasticity and neurotransmission. In(More)
Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as(More)
In the new classification of American Psychiatric Association - DSM-5 - a category of autistic spectrum disorders (ASD) was introduced, which replaced autistic disorder, Asperger syndrome, childhood disintegrative disorder and pervasive developmental disorder not otherwise specified. ASD are defined by two basic psychopathological dimensions: communication(More)
OBJECTIVES The current study established whether vomiting bulimic and/or non-bulimic depressive patients, both treated with a serotonin reuptake inhibitor (fluoxetine), have changes in their whole salivary secretion and inorganic components: Na(+), K(+), Ca(2+). METHODS From 108 female subjects, namely bulimics (Group B) (fluoxetine: 40 mg/day) (n=33),(More)
Disturbances of serotonergic neurotransmission and temperamental vulnerability have both been implicated in the pathogenesis of anorexia nervosa (AN). We genotyped the -1438 A/G polymorphism in the 5-HT2A receptor gene and serotonin transporter linked-polymorphic region (5-HTTLPR) in 132 adolescent subjects with AN and in 93 healthy controls. Personality(More)
Dysregulation of dopaminergic neurotransmission has been implicated in the etiology of major psychoses. The dopamine D(1) receptor (DRD1) plays a role in some brain functions and mechanisms of psychotropic drugs. Therefore, the DRD1 gene makes a good candidate gene for molecular genetic studies in schizophrenia and bipolar affective disorder. In the present(More)
