摘要:
The abnormal ϑ-rhythm of the EEG can be identified by use of spectral analysis. The rhythms appear as peaks in the power spectrum and can be considered as given, if the intensity of this peak is significantly higher than the average intensity and if a left-right coherence is present. Abnormal ϑ-rhythms in the parietal region are significantly more frequent in children with a history of febrile convulsions than in controls. This difference becomes especially obvious in the records with open eyes. According to previous investigations, the abnormal ϑ-rhythm is correlated with a genetically determined susceptibility to convulsio

摘要:
Petit mal absences in childhood are often followed by grand mal seizures in adolescence and a coexistence of both types of seizures is not uncommon at all. It is noteworthy, however, that such a coexistence does not imply immediate transition from one type of seizure into the other one. Hence, a grand mal attack may be preceded by all sorts of focal seizures, psychomotor automatisms or bilateral-synchronous myoclonus but immediately preceding petit mal (with generalized spike-wave discharges) is probably extremely rare.The presented case is characterized by unusually late onset of petit mal and grand mal seizures at age 32 and, following a mild head injury, a few episodes of petit mal status (ictal stupor) at age 52. At that time, a series of petit mal absences and eventually a smooth transition from petit mal to grand mal could be recorded. Uncommon frequency characteristics (especially some interspersed spiking at a rate of 9–15/sec) were found at the onset of the ictal spike-wave activity during the petit mal absences. This is regarded as the expression of failing inhibitory mechanisms which generally prevent the immediate development of a grand mal out of a petit mal absenc

摘要:
In patients with frontal lobe tumours the averaged visual evoked responses (AVER) and their dispersion pattern (DP) in visual areas were investigated before and at different periods after operation. Important changes in AVER (in amplitude and latency) were found in the patients with tumours on the midline or in one of the frontal lobes. The DP was abnormal in all the cases. There was no relation to visual acuity, tumour location and existence of intracranial hypertension. After operation, despite the clinical improvement, the alterations of AVERs or DPs were very marked and in some cases became even more important than before. The role of the frontal lobe in the organization of the responses to peripheral stimuli in the visual areas is discussed.

摘要:
A cerebral biopsy performed in an infant 9 months after accidental poisoning with chlorpromazine was studied. Light microscopy disclosed necrosing encephalopathy, while electron microscopy showed neuronal, glial, myelinic and vascular lesions. The findings in the present study suggest that the various neurologic syndromes appearing in cases of prolonged treatment with neuroleptic drugs and persisting after cessation of therapy would be due to consequent occurrence, in specific areas, of some irreversible cerebral lesions.

摘要:
The authors describe a case where a parkinsonian symptomatology is associated with pneumoencephalographic and RISA-cisternographic findings typical of an occult normal pressure hydrocephalus. They discuss their personal contribution in the light of what has been already reported in the literature on the same subject. They conclude that a CSF dynamics disturbance among the possible physio-pathogenetic mechanisms of an extrapyramidal syndrome in young subjects should be considered. On the other hand, they also emphasize the possibility that the occult normal pressure hydrocephalus may have syndromical expressions which are different from the typical one initially described.

摘要:
Measurements of various indices derived from arterial and jugular venous blood gas and pH values during temporary carotid clamping have been compared with measurements of cerebral blood flow and internal carotid artery pressure in 15 patients referred for carotid ligation. Cerebral venous blood gas measurements did not provide a reliable index of cerebral ischaemia.

摘要:
The morphology of thymuses removed from 16 cases of myasthenia gravis was studied in an attempt to correlate clinical response following thymectomy with the frequency of thymic germinal centers. In these patients, the presence of germinal centers in the thymus did not appear to influence response to thymectomy.

摘要:
16 patients suffering from syringomyelia were checked for additional peripheral nerve lesions. On voluntary effort, often in conformity with the decrease of muscle strength, a moderate rarefication of the discharge patterns was apparent. Fasciculation potentials were common. Motor conduction velocities of the median and ulnar nerve were in the normal range in cases without additional peripheral nervous lesion at the elbow or the carpal. Depending on the severity of the peripheral nervous lesion, we found the duration of the muscle action potentials increased.
