Anhedonia is a condition in which the capacity of experiencing pleasure is totally or partially lost, frequently occurring in mood disorders, as a negative symptom in schizophrenia, and in substance use disorders. In order to test a set of instruments for anhedonia in a population of detoxified opiate, alcohol and multiple substance-dependent subjects, 70(More)
INTRODUCTION Recent post-mortem studies of suicide victims have implicated brain-derived neurotrophic factor (BDNF) in suicide. Therefore, it was decided to examine the possible role of a gene in the regulation of BDNF activity in relation to suicidal behaviour among depressed patients. METHOD A series of 170 depressed patients were evaluated for their(More)
OBJECTIVE Behavioral deficits in sustained attention have been reported during both acute and euthymic phases of type I bipolar disorder (BD-I) and also in non-affected relatives of bipolar disorder (BD) patients. In particular, selective failure in target recognition was proposed as a potential trait marker for BD, but there are few studies exploring the(More)
AIMS Patients with dual diagnosis are often excluded from clinical trials although more than half of all individuals with Bipolar Disorder have a substance abuse problem at some point in their lifetime, representing a high-risk clinical population. The purpose of this study was to investigate the safety and efficacy of quetiapine in the treatment of alcohol(More)
INTRODUCTION The aim of this trial was to compare lorazepam with non-benzodiazepine medications such as pregabalin and tiapride in the treatment of alcohol withdrawal syndrome (AWS). These drugs were chosen for their inhibitorial effects on the hypersecretion of neurotransmitters usually observed in AWS. Craving reduction and improvement of psychiatric(More)
Pregabalin (PRE) acts as a presynaptic inhibitor of the release of excessive levels of excitatory neurotransmitters by selectively binding to the alpha(2)-delta subunit of voltage-gated calcium channels. In this randomised, double-blind comparison trial with naltrexone (NAL), we aimed to investigate the efficacy of PRE on alcohol drinking indices. Craving(More)
Several evidences support the hypothesis that glutamatergic dysfunction may be implicated in the pathogenesis of schizophrenia and in the last few years great interest has been focused on the role of the N-methyl-D-aspartate receptor (NMDAR). Glutamate is the main excitatory neurotransmitter in human CNS and it plays a prominent role in synaptic plasticity,(More)
Pregabalin is an anticonvulsant drug that binds to the α₂δ (alpha2delta) subunit of the voltage-dependent calcium channel in central nervous system (CNS). Pregabalin decreases the release of neurotransmitters, including glutamate, norepinephrine, substance P and calcitonin gene-related peptide. Purpose of this paper is to offer a qualitative overview of the(More)
The exact cause of schizophrenia is not known, although several aetiological theories have been proposed for the disease, including developmental or neurodegenerative processes, neurotransmitter abnormalities, viral infection and immune dysfunction or autoimmune mechanisms. Growing evidence suggests that specific cytokines and chemokines play a role in(More)
Anhedonia is a condition in which the capacity to experience pleasure is totally or partially lost. Although anhedonia is a feature of major depressive disorder according to DSM IV criteria for major depression diagnosis, so far it has received relatively little attention. The scale that is most commonly used in the measurement of anhedonia is the(More)
