Topiramate (TP), an anticonvulsant drug, has been widely used in the treatment of disorders characterized by impulsivity symptoms, so it goes to reason that it might be useful in addictive disorders. Recently, TP has been used to treat alcohol dependence, but it is still not known whether the effects of TP on alcohol consumption are related with its action(More)
Dopaminergic dysfunction in the prefrontal cortex (PFC) is involved in the pathophysiology of schizophrenia. In the PFC, dopamine signalling largely depends on the D1 receptors, which are coded by the DRD1 gene, and on the regulation of dopamine levels by the enzyme catechol-O-methyltransferase (COMT). Here, we investigate the role of DRD1 and its(More)
BACKGROUND Although many studies have established a close relation between impulsivity and alcohol use disorders, little is known about the role of behavioral impulsivity in the development of these disorders. OBJECTIVES To determine the role of 2 laboratory paradigms of impulsivity in the development of alcohol use disorders. METHODS Follow-up study(More)
Since Classical Antiquity numerous authors have linked the origin of some mental disorders to physical and functional changes in the pineal gland because of its attributed role in humans as the connection between the material and the spiritual world. The pineal organ was seen as a valve-like structure that regulated the flow of animal spirits through the(More)
The functional Val158Met polymorphism (rs4680) located at the gene that codes for the catechol-O-methyltransferase (COMT) has been extensively investigated in schizophrenia although current data are still controversial. Since COMT activity is sexually dimorphic, we carried out two independent studies in homogeneous samples of male and female Spanish(More)
CONTEXT Neuropsychological models of depression highlight temporoparietal hypofunction associated with low emotional arousal in major depressive disorder (MDD). These models were derived from indirect measures such as neuropsychological tests and electroencephalography alpha band power. OBJECTIVE To determine if high-arousing stimuli directly modulated(More)
Pathological gambling (PG) has been associated to both impulsiveness and attention deficit/hyperactivity disorder (ADHD) in different studies. Our objective was to compare different impulsivity and sustained attention variables, using both behavioural tasks and self-administered questionnaires, in a group of pathological gamblers with a history of childhood(More)
Inflammatory and immune processes have been implicated in the etiopathology of schizophrenia. We demonstrate the existence of immune function alteration, assessed by serum cytokine's levels, not only in schizophrenia patients but also in their unaffected first-degree relatives. This finding may provide a new data for considering cytokines as schizophrenic(More)
The cannabinoid receptor 1 gene (CNR1) has been associated with addictive disorders and schizophrenia in different studies. We have compared the frequencies of the alleles for the 3'-UTR CNR1 microsatellite in a sample of 113 Spanish schizophrenic patients, including 68 with comorbid substance abuse, and 111 healthy controls. We report that the frequency of(More)
BACKGROUND/RATIONALE Impulsivity has been associated with alcohol dependence, but impulsivity in alcohol-dependent subjects with a Cluster-B personality disorder (PD) has not been well characterized. Using a variety of laboratory measures of impulsivity, we assessed whether alcohol-dependent patients (ADP) with borderline personality disorder (BPD)(More)
