The aim of this study was to contribute to the characterization of the entactogen (ecstasy) substance group. The psychopathological, neuroendocrine and autonomic effects of common recreational doses of the entactogen 3,4-methylenedioxyethylamphetamine (MDE), the hallucinogen psilocybin, the stimulant d-methamphetamine and placebo were investigated in a(More)
BACKGROUND Criminal offenders with a diagnosis of psychopathy or borderline personality disorder (BPD) share an impulsive nature but tend to differ in their style of emotional response. This study aims to use multiple psychophysiologic measures to compare emotional responses to unpleasant and pleasant stimuli. METHODS Twenty-five psychopaths as defined by(More)
BACKGROUND Intense and rapidly changing mood states are a major feature of borderline personality disorder (BPD); however, there have only been a few studies investigating affective processing in BPD, and in particular no neurofunctional correlates of abnormal emotional processing have been identified so far. METHODS Six female BPD patients without(More)
Neurotoxic damage of central serotonergic systems has been demonstrated in numerous animal studies after exposure to methylenedioxyamphetamines (ecstasy). A high intensity dependence of auditory evoked potentials and, particularly, of the tangential N1/P2 source activity has been associated with low levels of serotonergic neurotransmission in humans. We(More)
Schizophrenic patients exhibit deficits in indices of sensorimotor gating, such as habituation and prepulse inhibition (PPI) of the startle reflex. Hallucinogenic drug-induced states are putative models for the early and acute stages of schizophrenic and schizophrenia-spectrum disorders. Hallucinogenic drugs have been shown to disrupt PPI and/or retard(More)
OBJECTIVE The aim of the study was to investigate affective responses to emotional stimuli in subjects with borderline personality disorder. METHOD Twenty-four female patients with borderline personality disorder and 27 normal female comparison subjects were examined. The test stimuli were a set of standardized photographic slides with pleasant, neutral,(More)
BACKGROUND The effectiveness of acamprosate (calcium bisacetylhomotaurinate) as a treatment to maintain abstinence in alcohol-dependent patients was assessed for 1 year. METHODS After short-term detoxification, 272 patients participated in a randomized, double-blind, placebo-controlled study. Patients received routine counseling and either the study(More)
OBJECTIVE Several studies have demonstrated that the presence of attention-deficit/hyperactivity disorder (ADHD) in childhood increases the risk of antisocial behavior developing in adulthood. However, because previous research did not consider comorbid conduct disorder (CD), the question of whether ADHD by itself or only the association of ADHD with CD(More)
The neurometabolic effects of the hallucinogen psilocybin (PSI; 0.2 mg/kg), the entactogen 3,4-methylenedioxyethylamphetamine (MDE; 2 mg/kg) and the stimulant d-methamphetamine (METH; 0.2-0.4 mg/kg) and the drugs' interactions with a prefrontal activation task were investigated in a double-blind, placebo-controlled human [F-18]fluorodeoxyglucoseFDG-positron(More)
Dysfunction of central serotonergic activity has been assumed in patients with borderline personality disorder (BPD) characterized by a prominent impulsive behavioral style. Following the high serotonergic innervation of the primary auditory cortex, there is increasing evidence of the intensity dependence of auditory evoked potentials (AEP), especially the(More)
