In vivo proton magnetic resonance spectroscopy ((1)H MRS) was used to study possible neurochemical abnormalities in drug-free, symptomatic panic disorder patients at rest. (1)H MRS was performed in 11 panic disorder patients and 11 healthy age- and sex-matched comparison subjects. Levels of brain metabolites were determined in the right medial temporal lobe(More)
OBJECTIVES The objectives were to compare the personality of fibromyalgia (FM) patients with other chronic painful and nonpainful disorders considering the confusion due to psychopathology and to assess the clustering of FM patients according to their personality profile. METHODS Differences in the NEO Five-Factor Inventory between FM, non-FM chronic pain(More)
PURPOSE To examine how cognitive, personality, and seizure outcome variables influence the subjective cognitive functioning of patients with refractory temporal lobe seizures after epilepsy surgery. METHODS Thirty-three consecutive patients with drug-resistant partial epilepsy who underwent surgical treatment at a tertiary referral university epilepsy(More)
OBJECTIVE To test the hypothesis that peripheral C nociceptor function may be abnormal in fibromyalgia and that C nociceptor dysfunction may contribute to the symptoms reported by these patients. METHODS Microneurography was used to record C nociceptors of 30 female patients meeting criteria for fibromyalgia and compared with recordings from 17 female(More)
The aim of this study was to examine clinical characteristics in patients with psychogenic nonepileptic seizures and to analyze the Minnesota Multiphasic Personality Inventory (MMPI) profiles and their relation to psychopathology. Thirty patients with nonepileptic seizures confirmed through video-electroencephalography were included. A structured clinical(More)
PURPOSE To study the power of CRF stimulation test to predict relapse in a sample of melancholic depressive patients in depressed phase, followed-up over a two-year period from the moment they achieved complete remission of depressive symptoms. METHODS Fifty-one outpatients diagnosed with unipolar depressive disorder with melancholic features according to(More)
PURPOSE Basal adrenocorticotropin hormone (ACTH) and cortisol levels and their response to corticotropin-releasing factor (CRF) test were studied in melancholic depressive patients in depressed state and recovery, and compared with healthy controls. METHODS Fifty-four outpatients diagnosed with unipolar depressive disorder with melancholic features(More)
Personality disorders (PDs) are still classified through categorical taxonomies that are at odds with current research findings. Dimensional models provide a suitable alternative for measuring individual differences. However, as they have traditionally lacked a clear definition of the "disorder" construct, the clinical utility of these models has been(More)
BACKGROUND There is growing evidence of a relationship between frontal neuroimaging and neuropsychological abnormalities and the physiopathology and course of late-onset major depression. AIMS To assess acute antidepressant response in late-onset major depression in relation to baseline frontal perfusion ratios. METHOD A 99mTc HMPAO single photon(More)
Given that the DSM taxonomy of personality disorders is flawed by severe classificatory problems, the development of alternative classificatory systems, such as the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), has now become a priority. This study examined the internal consistency, second-order factor structure, and(More)
