[Neuropsychological evaluation of the results of treatment of hydrocephalus using a ventriculo-atrial valve]. / Neuropsychologiczna ocena wyników leczenia wodoglowia zastawka komorowo-przedsionkowa.

In 25 patients with hydrocephalus of various grades and aetiology treated by insertion of ventriculoatrial valves neuropsychological investigations were carried out before and after this operation using the method of Luria and certain psychometric tests. The obtained results made possible isolation of three grades of impairment of higher nervous functions: III--afunction--10 patients, II--dysfunction--12 patients, I--eufunction--3 patients. Control neuropsychological examination two weeks after the operation demonstrated improvement of higher nervous functions in 6 cases with grade III and 11 patients with grade II impairment. In these cases radiological investigations demonstrated evidence of normotensive and hypertensive hydrocephalus and this was confirmed by measurements of intraventricular pressure of the cerebrospinal fluid. In 5 cases with grades III and II of damage no improvement was found. Radiograms and measurements of intraventricular pressure suggested in these cases hydrocephalus due to brain atrophy.

[Value of the neuropsychological examinations in the diagnosis of supratentorial gliomas]. / Wartosc badania neuropsychologicznego w diagnostyce glejaków nadnamiotowych mózgu.

The authors report an analysis of the results of neuropsychological investigations of patients treated for supratentorial gliomas. A syndrome of the most frequently observed disturbances of higher nervous activity has been outlined. The diagnostic, localizatlry and differential diagnostic value of neuropsychological investigations has been assessed and found to a useful auxiliary clinical method.

[Drawings by patients with unilateral visuospatial agnosia]. / Rysunki chorych z jednostronna agnozja wzrokowo-przestrzenna.

Drawings made by 25 patients with neurosurgical diseases causing focal lesions in the posterior areas of the right, not dominant cerebral hemisphere due to expanding changes. Experimental clinical investigations by the method of Luria demonstrated in these cases presence of left-sided visuospatial agnosia. The material was analysed from the point of view of the features of drawings characteristic for the syndrome of disturbances and the localizatory and diagnostic value of drawings. Characteristic disturbances of drawings and their placement were observed suggesting that the patients ignored the left half of the visual space due to damage to the right parieto-occipital non-dominant cerebral hemisphere. The drawing test is regarded as a valuable method for the diagnosis and localization of lesions in the neurological and neuropsychological practice.
