OBJECTIVE Schizophrenia is one of the most serious mental disorders. Music therapy has only recently been introduced as a form of treatment. The aim of this study was to examine the effect of music therapy for schizophrenic in-patients needing acute care. METHOD Thirty-seven patients with psychotic disorders were randomly assigned to an experimental group(More)
Electroencephalographically oriented research on vigilance needs valid measures for assessing the level of vigilance between wakefulness and sleep. When studying different psychologically, psychopathologically, and pharmacologically induced states, special attention has to be paid to minor alterations of the level of vigilance which are reflected,(More)
With the predictor problem in mind, we studied in-patients with endogenous depression whether relationships exist among the EEG, the therapeutic response, and the severity of psychopathology. We found that clinically defined responders and non-responders differ in respect of their average power spectra calculated for the two occipital regions. In addition,(More)
The relationship between auditory evoked potentials (AEP) and the German version of Zuckerman's Sensation Seeking Scale was examined. The slope of the amplitude/stimulus intensity function (N1/P2 component) and the N1 latency were particularly studied, as these variables have been found to be potential predictors of the response to lithium prophylaxis.(More)
The eye movements of 20 partially remitted schizophrenic outpatients (ICD-9) under neuroleptic maintenance medication and those of 20 normal controls were recorded using corneal reflection pupil-center measurement. The visuomotor performance during a 1-min picture viewing task was studied on the basis of several eye movement parameters. Clinical evaluation(More)
Up until now, no subclassification of affective psychoses has been validated biologically. This follows unavoidably from a research practice of defining diagnostic subtypes in consensus conferences and only thereafter allowing their validation. There is evidence that electroencephalograms (EEG) may be a useful tool in psychiatry, provided that the relevant(More)
About one third of manic patients show a decreased Electroencephalographic Vigilance Level (EVL). In two patients with recurrent manias the hypothesis was tested that the EEG may be used to predict the therapeutic response to methylphenidate. Patient A (with a decreased EVL) responded rapidly to methylphenidate with a considerable reduction of symptoms and(More)
