Positron emission tomography was used to study the effects of unilateral vascular thalamic lesions on cortical oxygen and glucose utilization in 10 patients. There was significant ipsilateral cortex hypometabolism in 9 of the 10 patients, affecting the whole cortical mantle diffusely. The only patient spared was free of neuropsychological deficit at the… (More)
The brain regional distribution and kinetics of [76Br]bromospiperone, a derivative of a neuroleptic (spiperone) labeled with the positron emitter bromine-76, were studied by time-of-flight tomography after i.v. injection in man. In a control subject the kinetic distribution study showed an accumulation of radioactivity which reached a maximum 3 h… (More)
For the Italian Multicentre Study on Dementia, a longitudinal survey on Alzheimer's disease (AD) initiated in 1982, we developed a neuropsychological test battery for screening, staging and monitoring cognitive impairment in AD patients and for delineating their pattern of cognitive decline. The tests measured higher cortical functions primarily involved in… (More)
The dementia associated with progressive supranuclear palsy (PSP) is considered to be subcortical because the cerebral cortex, unlike the subcortical structures, is usually free from major neuropathological lesions; the characteristic symptoms point to a dysfunction of the prefrontal lobe. The regional cerebral metabolic rate of glucose (rCMR Glu) was… (More)
Clinical, anatomical and functional findings in two cases of previous caudate nucleus hemorrhage, with good recovery, are presented. CBF data obtained with SPECT and 123 I-HIPDM well correlate with functional residual deficit, despite normal TCT examinations. These observations are suggestive of a partial "wallerian" diaschisis.
Blood levels of triglycerides, total cholesterol, isolated lipoprotein fractions (VLDL-LDL- and HDL-cholesterol) and apoproteins (Apo-A1 and Apo-B) were examined in multi-infarct dementia, senile dementia of the Alzheimer type, ischemic stroke associated with carotid atherosclerosis and in control subjects. Forty patients divided into 10 consecutive… (More)
We used positron emission tomography to study the effects of unilateral vascular thalamic lesions on cortical oxygen or glucose utilisation in 10 patients. There was a significant ipsilateral cortex hypometabolism in 9 of the 10 patients, affecting diffusely the whole cortical mantle. The only patient spared was free of neuropsychological deficit at time of… (More)
The authors describe their experience with imipenem-cilastatin in 36 patients in critical conditions due to multiresistant bacterial infections. The efficacy and tolerability of the antibiotic are stressed.
