Effects related to depth of verbal information processing were investigated in probable Alzheimer's disease patients (AD) and age matched controls. During word encoding sessions 10 patients and 10 controls had either to decide whether the letter "s" appeared in visually presented words (alphabetical decision, shallow encoding), or whether the meaning of(More)

Although an initial series seemed to show a correlation between hypersensitivity to tropicamide and intellectual impairment, subsequent testing showed a greater inter- and intra-individual variation than that between the(More)
A total of 228 children suffering from seizure disorders were investigated by means of cranial computerized tomography (CT). Their age ranged from 3 weeks to 15 years. Structural abnormalities were assessed in 63% of these cases. The greatest incidence of organic abnormalities occurred in children with major epilepsy (83%) and with focal seizures (71%).(More)
In 1977, more than 2,000 patients were examined in our department of neuroradiology by means of angiography, computed tomography, and in some cases also by pneumoencephalography. The value of the various neuroradiological examinations is discussed taking as an example two patients suffering from intracranial space-occupying processes of different(More)
An increased distance between brain surface, represented by the terminal arterial branches, and skull causes the appearance of a broad avascular band in the carotid angiogram, which--apart from other criteria--has been valued as a sign of cerebral atrophy. We investigated 54 patients (ages 60-79 years) suffering from cerebrovascular disease. Carotid(More)
