Non invasive study of carotid arteries by echo-doppler and metabolic abnormalities in patients with dementia.

In order to evaluate the prevalence of common and/or internal carotid stenoses together with metabolic abnormalities in dementia nineteen patients were investigated. Dementia and differential diagnosis between Alzheimer type (DAT) and multi-infarctual (MID) dementia were performed on the basis of Computerized Tomography scan, behavioural anamnesis, neurological and neuropsychological examinations. Eight patients were diagnosed as MID and 11 as DAT. Noninvasive study of neck arteries was performed in supine position by a Duplex Scanner, able of detecting a wide range of stenosis, even when very mild. Arterial hypertension, hyperlipidemia, diabetes and high hematocrit level were present in both groups, although to a higher extent in MID (p 0.05). Results from Duplex Scanner demonstrate 12 vascular stenoses 16-49% and one between 50-99% (13/76), being vascular abnormalities equally distributed among DAT and MID patients. These data suggest that patients with metabolic abnormalities and arteriosclerosis can develop dementia not necessarily of vascular type. On the other hand, MID patients do not present higher number of stenosis as compared to DAT, indicating that vascular disease of carotid arteries is not prominent in the clinical context of dementia.

Residual reading capability in a patient with alexia without agraphia.

A case of pure alexia due to an ischemic lesion of the occipital temporal region is described. Written words could be matched but not read. Immediate memory span for graphemes was defective. The reading defect probably depends on the inability to modify the written word "globally"; the phonological process was intact, but the memory disturbance impeded reading. The dissociation is explained by the preservation of word forms, which are linked to the semantic stage. Non-written stimuli trigger a "meaning" which evokes the word form and so the written word is recognized even though it cannot be read.

Sex differences in a children's spatial serial-learning task.

Boys (n = 80) and girls (n = 80) aged 9 to 10 completed a spatial-span test and a spatial serial-learning task. Corsi's block-tapping test was used for both. Sex differences were found on each: males performed better in both cases. The better performance of males on the spatial serial-learning task was independent of their superiority in the spatial-span test.

Sex and cultural differences in children's spatial and verbal memory span.

Spatial span (Corsi's block-tapping) and verbal span (Wechsler Digits Forward) were measured in 1113 children aged 4 to 10 yr. from urban and rural districts of the Regione Campania. Significant differences pointing to a better performance of the "town" group were found on both tests. Sex differences were found only on the spatial span test; boys performed better than girls.

Sex differences in adults' spatial and verbal memory span.

Spatial span (Corsi's block-tapping test) and verbal span (Wechsler Digits Forward test) were measured in 300 medical students (150 males and 150 females). Significant differences pointing to a better performance of males were found on both spatial span (p less than 0.001) and verbal span (p less than 0.05).
