In the past decade, a growing bulk of evidence has accumulated to suggest that patients suffering from major depression (MD) present some cognitive disturbances, such as impairment in attention, working memory, and executive function, including cognitive inhibition, problem- and task-planning. If the results of short-term memory assessment in depressed(More)
BACKGROUND/AIMS The aim of this study was to investigate the serotonin transporter (SERT), by means of the 3H-paroxetine ([3H]-Par) binding to platelet membranes, in patients affected by pathological gambling (PG), as compared with a similar group of healthy control subjects. METHODS Seventeen PG patients were selected amongst those who were drug-free and(More)
The present study explored the possible relationships between impulsivity, gender, and a peripheral serotonergic marker, the platelet serotonin (5-HT) transporter (SERT), in a group of 32 healthy subjects. The impulsivity was measured by means of the Barratt Impulsivity Scale, version 11 (BIS-11), a widely used self-report questionnaire, and the platelet(More)
Since the late 1960s, the serotonin deficiency, as demonstrated in major depression, was related to an increased activity of the liver enzyme tryptophan-pyrrolase stimulated by an excess of circulating corticosteroids, which would shift the metabolism of tryptophan from serotonin to kynurenine production. The finding that the kynurenine causes different(More)
BACKGROUND/AIMS A structural and functional interaction between A(2A) adenosine receptors and D(2) dopamine receptors has been implicated in the pathophysiology of impulse control disorders. The aim of this study was to use platelet membranes to assess A(2A) adenosine receptor affinity and density in patients affected by pathological gambling (PG; which is(More)
INTRODUCTION The rabbit syndrome (RS) is a rare movement disorder generally associated with prolonged use of antipsychotics and characterized by inwilling, rhythmic, fast and fine movements of oral and masticatory muscles along the vertical axis of the mouth. PREVALENCE The prevalence of RS ranges between 1.5% and 4.4%; middle and elderly ages, the female(More)
Although the beneficial effects of balneotherapy have been recognized since a long time, a few information is available on the biological mechanisms underlying them and the subjective feelings of increased well-being and mood. The links between the serotonin (5-HT) system and mood prompted us to investigate the 5-HT platelet transporter (SERT), which is(More)
The present study aimed at investigating the possible changes of some features of loving relationships during long-term treatment of depression with both selective serotonin reuptake inhibitors (SSRIs) and tricyclics (TCAs), by means of a specifically designed test, the so-called "Sex, Attachment, Love" (SALT) questionnaire. The sample was composed by 192(More)
AIM Although the precise nature of pathological gambling (PG) is still elusive, currently it is considered an impulse-control disorder that shares several features with substance dependence, such as deficit in self-regulation and impaired impulsivity. The aim of this study was to evaluate the impulsivity of PG patients by means of the Barratt Impulsivity(More)
A large amount of the data gathered in the last 50 years support the hypothesis that alterations of the serotonin (5-HT) neurotransmission play a crucial role in the pathophysiology of not only major depression (MD), but also of different neuropsychiatric disorders. Research in this field has been substantially promoted by the evidence that the reuptake(More)
