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)
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)
Clinical evidence suggests that hallucinogenic drug-induced altered states of consciousness (ASCs) and the incipient, acute stages of endogenous psychoses share many common phenomenological features. The aim of our study was to assess hallucinogen-like phenomena in endogenous psychotic patients using standardised methods. We examined 93 endogenous psychotic(More)
The aim of this study was to assess psychophysiological affect correlates, in addition to the usual self-report in borderline personality disorder (BPD) compared with avoidant personality disorder (APD) and normal controls (NCs), when responding to standardized experimental stimuli. In 24 BPD female patients, 23 APD female patients, and 27 female NCs, skin(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)
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)
UNLABELLED SPECT/PET studies in schizophrenia revealed inconsistent changes of regional cerebral blood flow (rCBF). Frontal hyperperfusion as well as hypoperfusion are described. This study was undertaken to investigate the relations between rCBF, psychopathology according to PANSS and effects of neuroleptic therapy. METHODS Twenty-four drug-naive acute(More)
