With the Structured Psychopathological Evaluation-System (SPES) an instrument existed for employment of objective criteria. This study was designed to present an evaluation system based on new scientific results, that is applying on the strength of a reduced catalogue of symptoms (94 compared with 198 Items at SPES-A) to clinical routine. Additional findings differentiated by this system be able to classify by the help of an operational decision system.  相似文献

295 expert opinans of the NVA (National People's Army) in conditions after craniocerebral traumas for which an EEG findings was present were subjected to an retrospective analysis to determine the importance of EEG for export opinion. In 59.3% of cases EEG was significant for expert opinion, but was of prime importance only in 1.3%. In 161 expert opinions the total damage of the body was determined. This gave the possibility of a statistical correlation of individual EEG findings with the extent of the body damage. Mean percentage values of the individual degrees of severity of EEG changes could be calculated on the basis of these data. The great importance of EEG for military medical opinion could also be confirmed in comparison with 8 other clinical data and findings.  相似文献

The relationship between endogenous-psychotic and hysterical behavior is presented in this paper on the basis of typical patients' accounts. Various patterns of behavior are revealed: chronic hysterical psychotic syndromes, acute hysterical psychotic syndromes, hysterical exalted psychotic episodes, simulated hysterical psychotic syndromes, hysterical behavior in the attempt to cope with psychosis, and pseudohysterical behavior in endogenous psychoses. The specific aspects of the doctor-patient relationship in the case of these patients are described.  相似文献

The influence in 8 of our patients with ophthalmic migraine of photic driving with sine-like flashing lights on EEG background activity was checked and the visually evoked potentials following the application of diffused simple light stimuli were analyzed using the recovery cycle technique. The results indicate a slightly increased tonic activity of the structures of the mesencephalic formatio reticularis, such as may be produced by slight functional disturbances. Some vegetative secondary symptoms of migraine attacks and some of the changes in EEG observed in patients with ophthalmic migraine are explicable by such an abnormality.  相似文献

The contribution deals with the critical transition from ward treatment and follow-up care as an outpatient. Patients with primary psychic maldevelopment are compared with those of a secondary psychic development. Changes in symptoms and personality were measured with a battery of tests during a pre-post follow-up study (intervals of eight weeks between tests). Special attention is paid to changes after discharge from hospital and deterioration, which was common among the patients with secondary psychic maldevelopment, is discussed.  相似文献

Subjective differences in EEG evaluation are demonstrated by means of a seven step scale for grading the unspecific hyperventilation effect in 3263 EEG of children. Intermediate steps of this scale allow to minimize such unavoidable differences.  相似文献

Hitherto it has not been usual to talk in the German language about the therapy-oriented concept of two forms of the progress of atypical depression (Type A and Type V). The characteristic symptom of Type A is angst, together with phobias, physical complaints, etc. In Type V there are vegetative symptoms, often towards evening (Hypersomnia, difficulty in getting to sleep, increased appetite, increased weight, increased libido), accompanied by hysterical extrovert personality traits, and of intermittent occurrence. These clinical pictures are amenable to psychopharmalogical therapy. In conformity with the assumption of "somatic accommodation" treatment with antidepressives is recommended in the case neurotic depression, too, at least in the initial stages of treatment.  相似文献
