The results of an evaluation of the perfusion scintigraphy findings of 350 hospitalised neurological patients and 55 more strictly selected neurosurgical patients with cerebrovascular complaints, revealed an accuraty of 83%, a sensitivity of 89%, and a specificity of 83%. The selection of the patients had no influence on the results as a whole. Compared with contrast-medium angiography, incorrect diagnosis must be expected in 17% of the cases. This includes erroneous negative findings in 10% of the cases. Grounds for misinterpretations are suggested, and the biological and methodological limitations of the method are set forth. 相似文献

The paper is concerned with an attempt to generalize and categorize current hypotheses on the biochemical basis of ECT. The hypotheses are critically evaluated with respect to the relevance of their experimental fundamentals. Thus, certain hypotheses are valid only in a qualified sense. Particular interest is focussed on those conceptions which try to correlate ECT-induced changes in synaptic receptor sensitivities (up-/down-regulation) with super- resp. subsensitivity hypotheses of psychoses. In this connection, noradrenergic and opioid systems on the one hand, and the axis hypothalamus-hypophysis on the other hand seem to play a dominant role. 相似文献

The use of computer based diagnostic decision and artificial intelligence are discussed in relation to the problems of validity and reliability of psychiatric diagnoses. The authors suggest a definition of a computer aided classificator as an existent decision system for an automatically analysis of findings. 相似文献

This paper explores the significance of Marie Bonaparte's book, Topsy: The Story of a Golden Haired Chow. The manifest importance of Topsy has been attached to the fact that the Freuds translated it out of gratitude to Bonaparte and because of their love for dogs. Another level of significance emerges when the book is placed in historical context. Topsy elucidates the relationships between Marie Bonaparte, Sigmund Freud, and Anna Freud. It reflects Bonaparte's feelings about Freud's illness and is part of an ongoing dialogue with him. The persistent misplaced emphasis on the "dog story" has obscured the more profound issues. The author suggests that the conflicting needs to appreciate transience and to avoid mourning may account for both the importance of the book and for its obscurity. 相似文献

An investigation into the diagnostic value of psychometric methods for the diagnosis of depressive states involved five psychometric questionnaires, one concentration test procedure, and one problem-solving approach to register cognitive processes. The data obtained for 80 depressive patients of varied aetiology were compared with those of sample of 80 neurotics without depressive aberration. Even univariate comparisons revealed statistically significant differences between the two samples. Multivariate methods (factor analysis, discriminative analysis) yielded more differentiated information. The "Scale for depression depth measurements" was found to be of particular diagnostic relevance; it was standardized for the time being. 相似文献

In this study we investigated the immediate and continued impact on women of a major stressful event, the outcome of pregnancy, and the mitigating effect of self-esteem and intimacy with their spouse on their reactions. Few other studies have investigated initial reactions to crisis events. Ninety-nine Israeli women who experienced either normal delivery or pregnancy complications were interviewed at the time of the event and 3 months later. High self-esteem was found to limit feelings of depression at both times. Intimacy with spouse limited depression at the event, but not at follow-up. High self-esteem was seen as always being exploitable by women who possessed it, whereas the benefit of intimacy with spouse was seen as being dependent on situational demands and environmental constraints. Cross-cultural implications were presented. 相似文献
