Abstract

The echo-encephalogram is a valuable addition to neuropsychiatric diagnostic equipment. In contrast to pneumencephalography which is accompanied by subjective complaints and a certain risk (although this risk is very slight when the procedure is carried out correctly), echo-encephalography is a harmless investigation that can be repeated at will, requiring little time and a minimum of equipment and personnel. It is particularly suitable for longitudinal examinations and in contrast to pneumoencephalography, it may be performed on outpatients. Obviously, the information that can be obtained regarding the position of the midline structures and the size of the ventricles, is very important for neurological and psychiatric investigations, as well as for legal purposes, even if this information is only approxiamte. To test the probability of error and the validity of echo-encephalography, data regarding the midline structures and the width of the third ventricle, obtained with the ultrasonic method on 125 patients at our clinic were compared to the findings on pneumoencephalograms. The diagnosis of the examined patients included epilepsy, head injury, cerebrovascular disease, degeneration processes, neurosis and brain tumor. The age of the patients ranged from the first to the seventh decade; on the age distribution curve the peak lay at the middle decades.
