摘要:

Electromyographic (EMG) examinations were performed twice within two weeks in the same 41 muscles of 32 volunteers. Frequency analysis of the EMG signal showed a pathological high‐frequency deviation at the second examination in seven (21%) of the muscles re‐examined during the first week. Serum creatine kinase values were higher on the third than on the first day in 11 out of 13 individuals, but the values never exceeded the upper normal limit. A further 10 volunteers were investigated by a single EMG examination followed by a single muscle biopsy. No significant abnormalities were found in the specimens. Owing to the frequency spectrum shifts it is recommended that not less than two weeks should elapse between EMG examinations in the same mus

摘要:

In a prospective investigation of 55 consecutively selected patients with right‐sided apoplectic lesions, denial and neglect of hemiparesis was registered in a standardized way using fixed criteria.The patients were all fully conscious and could cooperate in a detailed investigation. About half of the patients had denial and neglect of hemiparesis (1/4 denial, 1/5 neglect). The syndrome(s) of denial/neglect was not related to sensory defects or defects in the sense of position. Denial of hemiparesis was related to extent of lesion, neglect of hemiparesis was not. Both syndromes were related to age of patients. The resemblance between denial and neglect of hemiparesis is pointed out. It is argued, that the two phenomena could be seen as one syndrome released by right‐sided brain lesions, the difference being a matter of degree. The cognitive factors in denial/neglect are thought upon as factors, than can be seen in right‐sided lesions together with paresis, visual defects, but apparently not necessarily associated with the named de

摘要:

Fifty‐five patients with right‐sided apoplectic brain lesions prospectively and consecutively collected, were analyzed as to the frequency of visual neglect. The syndrome was present in 18 patients, 10 of whom had left hemi‐ or quadrantanopia. In addition, two patients had anopia with Anton's syndrome.Only the visual neglect without visual field defects was closely related to denial of hemiparesis.The two components of the syndrome of visual neglect, defects in registering visual information from the left side and defective appreciation of own condition are described and analyzed.Psychological theories of the processes behind the syndrome of neglect have difficulties in joining the cardinal features of the syndrome satisfactorily. Theories on the specific role of the right hemisphere in connection with attention/arousal and complex gnostic functions are referred to in the discussion of the syn

摘要:

Four circulation time parameters were measured by intravenously injected99mTechnetium and a gamma camera in 183 patients displaying a unilateral supratentorial brain infarction. The mean values of all the calculated circulation time parameters in the infarcted hemisphere were significantly slower than those of the contralateral hemispheres. The difference between the hemispheres proved a more sensitive parameter than absolute values. Both the quantitative circulation time differences between the hemispheres and the absolute circulation tune values showed significant correlations with several clinical findings, e.g. severity of infarction, recovery from infarction, and patient's age. However, quantification gave only a minor addition to the number of the patients with abnormalities detected by routine static and dynamic brain scintigrams. Though the value of the quantitative intravenous99mTechnetium method in routine clinical work is limited, it provides valuable information on the haemodynamics in brain infarction, e.g. the persistence of measurable asymmetry suggesting decreased function even of non‐infarcted parts of the affected hemisphere (“deafferentiatio

摘要:

Benzodiazepines given intravenously abort status epilepticus, and abolish paroxysmal EEG discharges. The study reported concerns the effect of small doses (about 1 mg) of lorazepam on these EEG changes, assessed visually, in the resting record, as well as during overbreathing and photic stimulation. Thirty patients were examined, approximately half had primary generalised and the remainder focal epilepsy. All showed rapid reduction of paroxysms in the first few minutes following injection. This occurred faster and was much more persistent for the generalised than for the focal group. The effect of chronic oral administration of lorazepam in these patients is under investigation.

摘要:

The present study was performed on Milan residents, in order to evaluate the risk of acquiring multiple sclerosis between patients born in Milan and patients born in Southern Italy. For this purpose, 216 consecutive subjects with definite or probable multiple sclerosis, inmates of the Neurological Institute C. Besta (Milan) from 1968–1976, were matched with 216 controls, uniform as regards age, sex, profession and residence, who were hospitalized at the same time for other neurological diseases. Comparing the case/control pairs for the migration, we observed that the North‐Centre born had a relative risk of acquiring the disease significantly superior to one (RR = 1.9;P= 0.01) as compared to migrants from the Southern regions of It

摘要:

The influence of sex, age, educational level and pathologic lesion on incidence, severity and clinical form of aphasia was investigated in 390 right‐handed, left brain‐damaged patients. Sex and educational level were not related to any parameter. Etiology of lesion and age were related to both incidence and type of aphasia. Incidence of aphasia increased with age and was higher in patients with cerebrovascular accidents than in subjects with other types of brain lesions. Non‐fluent forms of aphasia were more frequent in young patients suffering from acute cerebrovascular accidents, whereas anomia prevailed in neoplastic subjects and Wernicke's aphasia increased regularly in frequency with age. Some tentative explanations of these findings are disc
