Exceptional musical performance in early childhood catatonia

Many years ago the author, jointly with a psychologist, described a patient who, in spite of her alleged idiocy, showed an exceptional musical capacity. However, in the meantime the author has recognized and described early childhood catatonics and, as a consequence of this new knowledge, he has to admit an error. Even according to our then findings it would have been identifiable that, as has been confirmed now by follow-up, the patient is suffering from catatonia, starting in infancy. The high musical performance, then arousing our greatest astonishment, is now explicable, for childhood schizophrenics do not develop general mental deficiency but only specific circumscribed deficits.     

Has the cataphasic form of schizophrenia increased in modern times?

According to our investigations the incidence of cataphasia, which is a subtype of schizophrenia, has become more common in the last years and on average, has started earlier in life. As the central disorder of this illness concerns thinking perhaps there exists a relation of our finding to the rapid modern development of techniques, insofar as the cognitive function is overstrained in childhood and adolescence, when the nervous system has not matured yet. Introverted individuals seem to be at a particular risk. However, it must not be disregarded that cataphasia is an inherited illness which cannot be caused by external influences, but can only be promoted in its manifestation.     

Communication-promoting exercise therapy in a closed male psychiatric ward

The use of the communication-promoting gesture therapy in a locked psychiatric men's ward led to the result, that a part of the restlessness and aggression potential of the patients could be commuted into a constructive social behaviour. Simultaneous increased frankness and confidence of patients in physicians and male nurses. A tied group doesn't seem to be a condition for that.     

Subjective factor in EEG evaluation exemplified by the nonspecific hyperventilation effect

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.     

Behavior of visual evoked potentials (pattern reversal VECP) in smokers

Twenty six clinically healthy smokers were studied with transient pattern visual-evoked potentials. In comparison with a sample of "normal" subjects we found a difference of some parameters (P less than 0.05): the P2-latency and the interocular difference of latency on average were 6-7 ms respectively 2 ms larger. Thirteen subjects have had a prolonged P2-latency (P less than 0.05) and/or a difference in interocular latencies larger than 5 ms. These findings may suggest on subclinical disturbances of visual system and indicators of an special sensitivity of that person. The findings are possibly related to tobacco-alcohol amblyopia.     

Validity of post-proline splitting dipeptidyl aminopeptidase activities in the cerebrospinal fluid for neurologic and psychiatric diagnosis

The dipeptidyl-peptidase activity of 650 liquores cerebrospinalis was obtained by means of the substrate Gly-Pro-NHNp (Gly-Pro-4-nitroanilid) at pHs of 5.5 and 7.4. In comparison with a reference collective, the suitability of the method as a supplementary liquor parameter in neurological psychiatric diagnosis was examined. The introduction of the measurement at pH 7.4 can be particularly recommended for the distinguishing of bacterial and nonbacterial meningitis.
