Creativity is important for social survival and individual wellbeing; science, art, philosophy and technology have been enriched and expanded by this trait. To our knowledge this is the first study probing differences in brain cerebral blood flow (CBF) between highly creative individuals (scientists and/or artists socially recognized for their contributions(More)
In this study, we investigated whether polymorphisms of the dopamine D4 receptor (DRD4) gene were associated with psychotic symptomatology rather than with a unique diagnosis such as schizophrenia. A number of association studies between the DRD4 gene 48 bp-VNTR polymorphism at exon 3 and psychotic disorders have been reported, but the results have been(More)
Sleep patterns, frequently altered in depression, have been hypothesized to be under genetic control. The circadian locomotor output cycles kaput (CLOCK) T3111C variant has been studied in association with sleep disturbances in depressed patients. The aim of this study was to investigate possible effects of T3111C CLOCK on insomnia, daytime sleepiness,(More)
The BDNF is required for the development and proper function of the central nervous system, where it is involved in a variety of neural and molecular events relevant to cognition, learning, and memory processes. Although only a functional mature protein is synthesized, the human BDNF gene possesses an extensive structural complexity, including the presence(More)
Serotonin (5-HT) induces concentration-dependent metabolic effects in diverse cell types, including neurons, entherochromaffin cells, adipocytes, pancreatic beta-cells, fibroblasts, smooth muscle cells, epithelial cells, and leukocytes. Three classes of genes regulating 5-HT function are constitutively expressed or induced in these cells: (a) membrane(More)
A putative role of the brain-derived neurotrophic factor (BDNF) in epilepsy has emerged from in vitro and animal models, but few studies have analyzed human samples. We assessed the BDNF expression of transcripts with exons I (BDNFI), II (BDNFII), IV (BDNFIV) and VI (BDNFVI) and methylation levels of promoters 4 and 6 in the hippocampi of patients with(More)
BACKGROUND The interplay among lifetime adversities and the genetic background has been previously examined on a variety of measures of depression; however, only few studies have focused on major depression disorder (MDD) in adolescence. METHODS Using clinical data and DNA samples from mouthwash gathered from an epidemiological study on the prevalence of(More)
The etiology of attention deficit hyperactivity disorder (ADHD) is complex and multifactorial, with an important genetics load. Pharmacological, animal, and brain image studies provide significant evidence that monoamine genes are relevant (Gizer et al., 2009). We aimed to explore the possible association between Val158Met COMT, VNTR 3 0 UTR SLC6A, and LPR(More)
Excessive daytime sleepiness (EDS) is a symptom with high public health importance. Within psychiatric settings, depression is the most significant risk factor for EDS; however, this relationship has not been clearly detailed. The aim of this study was to describe the quality of sleep of depressed patients with and without EDS and to investigate the(More)
BACKGROUND Obsessive thoughts and compulsive drinking behaviors have been proposed as key factors associated with the loss of control over alcohol consumption experienced by alcohol-dependent patients. The self-report 14-item Obsessive Compulsive Drinking Scale (OCDS; Anton et al., 1995) was designed in order to rate these features. METHODS A(More)
