Psychologic effects of taurine in epileptics having partial seizures with complex symptomatology
No full textPsychological variations after taurine treatment (150 mg/kg/die i.v.) in ten partial seizures with complex symptomatology epileptics have been valued by means of Wechsler-Bellevue Intelligence Scale, Wechsler Memory Scale, Cattel's Retentivity Test, Raven's Progressive Matrices 1947, Mira Stambak's Test and Oseretzky's Test. The findings of the group of patients treated with taurine have been compared to results of another group of ten similar patients treated with placebo. At the base conditions, mean values of mental tests were similar in both groups. After treatments, improvement of mean scores has been observed in only the group treated with taurine, concerning intellectual performances in toto, and in detail intellectual vivacity and quickness, interest of surrounding environment, motivation, attention, memory and psychomotor capacities. These data indicate the employment of taurine in epileptics also to improve intellective functions
EYE TRACKING NELLE COREE CRONICHE
No full textIn 8 cases of chronic chorea, 5 of which were of familial nature, the 'smooth pursuit' ocular movements were recorded by means of 'eye tracking', comparing them with those of a group of normal subjects of the same age devoid of neuropsychiatric pathology. The recording of the ocular movements of choreic subjects turned out to be quite different from the normal recordings in which the oculogram (EOG) is a continuous and regular sinusoid. In choreics the EOG was an irregular tracing with changes that affected the entire test, or part of it. The recording of the first of the EOG, which expresses the velocity of the movement, showed in choreics 'arrests' and 'positive errors' of velocity in a significantly higher number than in normal subjects
Nistagmo spontaneo da lesione del sistema nervoso centrale e fasi del sonno
No full textE' stato studiato l'effetto del sonno notturno sul nistagmo spontaneo in 10 pazienti affetti da lesioni "centrali" delle vie vestibolari, per ezilogie diverse. Sono state effettuate registrazioni poligrafiche notturne. E' stata evidenziata una alterazione del sonno REM in tali pazienti, sottolineando la necessità di integrità dell'apparato vestibolare nel sonno REM. Il nistagmo spontaneo dovuto a lesioni del SNC è scomparso alle prime fasi dell'addormentamento e non è stato più rinvenuto durante le varie fase del sonno NREM nè in molti casi del sonno REM. Ciò sarebbe dovuto ad influenze inibitrici da parte dei meccanismi del sonno sulle strutture del tronco intercalate sulle vie del riflesso vestibolo-oculomotore
