The validity and reliability of using psychological autopsies to diagnose a psychiatric disorder is a critical issue. Therefore, interrater and test-retest reliability of the Structured Clinical Interview for DSM-IV Axis I and Personality Disorders and the usefulness of these instruments for the psychological autopsy method were investigated. Diagnoses by(More)
The possible predictive value of regional cerebral perfusion patterns with respect to the response to partial sleep deprivation (PSD) was evaluated in 15 major depressive patients (mean age = 54.9 years, mean Hamilton depression score = 21.6). Patients were studied with single photon emission computed tomography with technetium-99 m-D,L-hexamethyl-propylene(More)
HMPAO-single photon emission computerized tomography (SPECT) is a useful technique in studying cerebral blood flow (CBF). This method is suitable to evaluate the differences of CBF with reference to total sleep deprivation (TSD) within 24 h because of the short half-life of the radiopharmaceutical compound. In the present study, CBF before and after TSD was(More)
Thirty-nine subjects with chronic insomnia were treated with L-tryptophan (L-TRP) in a double-blind, cross-over study. Instead of a placebo, a very low dose of 0.04 g L-TRP was used. The subjects suffered from a sleeping disorder classified as "psychophysiological, persistent". In the subgroup taking the full L-TRP (2 g) dose first, there was a significant(More)
The authors study the frequency of primary enduring negative symptoms in first-admission patients with schizophrenic and non-schizophrenic disorders. Carpenter's criteria for distinguishing the primary, enduring negative symptoms from the more transient negative symptoms (secondary to different factors) were applied. Furthermore, they compare negative(More)
The objective of this study was to determine the impact of work-related factors on risk for completed suicide. Psychiatric disorders and socio-demographic factors including work-related factors were assessed by a semi-structured interview using the psychological autopsy method in 163 completed suicide cases and by personal interview in 396 living(More)
The incorporation rate of 14C-labeled arachidonic acid (14C-AA) into membrane phospholipids was measured in a group of untreated (greater than 6 months) psychiatric patients (n = 33) and healthy controls (n = 31). Platelets from controls and from patients with schizophrenia (n = 10), schizophreniform disorder (n = 11), schizoaffective disorder (n = 6),(More)
AIM The association between sporting activities, or lack there of, and suicidal behaviour has not yet been clarified. The objective of this study was to determine, if sports participation has an impact on risk for completed suicide. METHODS Axis I and Axis II disorders, sociodemographic factors, and current and former sports activities, including various(More)
Twenty-five subjects suffering from severe chronic insomnia were treated for four weeks with 2 g of L-tryptophan in combination with a schedule of varying sleeping times which caused a sleep deficiency at the beginning of treatment. A second four-week period without L-tryptophan was used as a control. Nineteen subjects (76%) experienced a markedly improved(More)
Platelet monoamine oxidase (MAO) activity and personality characteristics were correlated in a sample of 52 men (37 +/- SD 13 years) and 54 women (37 +/- SD 15 years) from a rural community. Personality characteristics were measured by using the Freiburger Persönlichkeitsinventar (FPI-A). In males, weak but significant linear correlations (Pearson(More)
