In view of the higher prevalence of severe ischemic stroke among patients with atrial fibrillation (AF) and of the recently reported higher frequency of stroke with AF in females, 516 consecutive patients with ischemic stroke, of whom 93 had AF, were retrospectively evaluated. The main anamnestic, clinical and laboratory features of the AF and non-AF groups(More)
311 cases of spinal cord softening, were selected for review. The following points emerged from this study: 1) spinal cord softening is a rare occurrence; 2) while formerly syphilis was the most frequent cause, recently reports of cases secondary to aortic disease or to embolism with diffuse signs of arteriosclerosis and circulatory failure pointing to a(More)
The properties of errors made by normals and unilateral brain damaged patients in localizing points in each half of a plane have been further investigated. A lesion of either hemisphere affects specifically the performance in the left half of the plane, where controls attain the highest degree of constancy. Consideration of the orientation of pathologic(More)
To complete our bibliographic review of spinal cord softenings, we now discuss the clinical and pathological findings in the cases of known or probable cause. Comparison of the diagnostic groups yields some differences in respect of sex, age and mode of onset, survival and extent of the anatomical lesion. Further differences, especially in age at onset,(More)
Two stimulus configurations (gratings and checkerboards) have been presented to a series of consecutive patients with the aim of exploring VEP changes in Parkinson's disease. The outcome turned out to be quite different according to the stimulus employed. Specifically, grating pattern produced a high diagnostic yield as opposite to checkerboard, which did(More)
86 patients suffering from various senile and presenile degenerative diseases were studied using scinticisternography with In111-DTPA. Flow reversal and delayed clearance were observed in 62 of these patients. These alterations, possibly related to the cerebrospinal fluid dynamics, show the aspecificity of the SC picture. The SC picture does not seem to be(More)
A group of 6 patients undergoing cervical spinal cord stimulation (SCS) because of different pathologies was studied. Multipolar leads (QUAD-Medtronic) were inserted percutaneously; following an SCS test period, leads were connected to a multiprogrammable, fully implantable generator (ITREL II). Neither surgical nor other side effects were found. Regional(More)
Autosomal recessive inherited ataxias are a growing group of genetic disorders. We report two Italian siblings presenting in their mid-50s with difficulty in walking, dysarthria and progressive cognitive decline. Visual loss, ascribed to glaucoma, manifested a few years before the other symptoms. Brain MRI showed severe cerebellar atrophy, prevalent in the(More)
