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 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)
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)
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)
BACKGROUND Studies of schizophrenia by single photon emission computed tomography (SPECT) and positron emission tomography (PET) have shown both regional cerebral hyperperfusion and hypoperfusion. The aim of this study was to examine the inter-relations between regional cerebral blood flow (rCBF), psychopathology, and effects of neuroleptic therapy. (More)
Affective instability in borderline personality disorder is due to a marked reactivity to environmental events. The present study focused on the relationship between affective instability and impulsivity in personality disorder. It used an experimental approach in the form of an affect-stimulation design based on the presentation of a short story which(More)
This paper examines impulsivity as a central factor in moderate/superficial self-mutilation such as skin-cutting and burning. A sample of 165 subjects were divided into four groups, namely self-mutilators, patients with any modes of impulsive behavior other than self-mutilation, patients without any impulsive behavior, and normal probands. All were(More)
Hallucinogenic drug-induced states are considered as models for acute schizophrenic disorders (experimental psychoses). In a double-blind study with healthy volunteers we investigated the influence of the serotonergic hallucinogen psilocybin, the ecstasy-like drug 3,4-methylenedioxyethylamphetamine (MDE), the stimulant d- methamphetamine and placebo on(More)
