Twenty-one Parkinsonian patients were tested in on and off phases during chronic levodopa therapy for cognitive function, affective status, and evaluation of motor performance with reaction and movement times. A worsening of mood was observed from the on to the off phase. No variation in cognitive performance was observed from the on to the off phase in(More)
The present retrospective analysis reports two studies. In Study 1, clinical aspects of aphasia are compared in right-handed (RH) and non-right-handed (NRH) patients; in Study 2, recovery from aphasia is compared in RH and NRH aphasic patients with a minimum of 5 months of daily language rehabilitation. From a continuous series of 1200 brain-damaged(More)
Introduction. To a smooth manifold M one can associate in a natural way a new smooth manifold, the manifold of k-jets of n-dimensional submanifolds of M, indicated by G (k) n (M), which parametrizes in a smooth way the k-jets of immersed submanifolds of M. On G (k) n (M) one can build in a canonical way a differential ideal, denoted Ᏽ (k). The cohomology(More)
We report two female patients who became global aphasic following a large left hemisphere lesion. With passage of time they recovered to a considerable extent, but three years and six months, respectively, after the former CVA, a new stroke lateralized to the right hemisphere occurred and they showed a definite worsening of language disturbances.(More)
119 patients were enrolled in a double-blind randomized parallel study versus placebo carried out to assess both the efficacy and tolerability of L-deprenyl (10 mg/day) for treatment of patients with organic mental disorders of the Alzheimer type (DAT). The treatments were given for 3 months, starting after a run-in period of 15 days to evaluate efficacy. A(More)
Eighteen patients with Huntington's chorea were examined before and after neuroleptic treatment (haloperidol, pimozide, tiapride) to study the effect of such treatment on hyperkinesia and motor performance. Pimozide and haloperidol improved hyperkinesia; none of the drugs significantly affected motor performance. No correlation was found between the(More)
This retrospective study aims to assess cognitive involvement in pre-AIDS, not drug abuser subjects and to determine whether CD4 status or disease stage best correlates with cognitive changes that may portend development of ADC. 328 cases were analyzed. No differences in psychometric performance in relation to CDC stage were found. Instead, patients with(More)
Fifty-eight HIV-positive drug abusers and 22 HIV-positive nondrug abusers at stages II-III and IV of the Centers for Disease Control classification were evaluated neuropsychologically. The study confirmed previous findings that drug abuse has a negative influence on cognitive function. It also emerges that seropositivity affects cognitive function, although(More)
