[Neurologic, electro- and echoencephalography studies of former high-risk children and control children].

First results of neurological, electro-encephalographic and echo-encephalographic examinations obtained from three different groups consisting of former high-risk babies (about two thirds) and control children (about one third) are presented. As was to be expected, the control group showed remarkably fewer findings which differed from the physiological variation width. The comparatively high proportion of individual results without pathological findings obtained from high-risk children indicates that reliable diagnostic conclusions can be drawn only if the results of various examination techniques are summarized. The analysis of a neurological longitudinal study of former high-risk infants reveals a trend toward recession of the neurological peculiarities over the observation period which lasted until the sixth year of age. This particularly applies to light phenomena of a neurological character which do not have syndrome character and are pathologically irrelevant. As a result of different interpretations of what "high risks" are, considerable problems can arise when the results of examinations performed on groups of high-risk children by various workers are to be compared.
