The accuracy of computed tomography, electroencephalography, and clinical features in the differential diagnosis of senile dementia was studied prospectively. Out of 50 demented patients, autopsy revealed 32 cases with either senile dementia of the Alzheimer's type (SDAT), multi-infarct dementia (MID), or a combination of both. Eighteen patients had(More)
The objective of this report is to investigate whether smoking exerts any influence on the number of senile plaques and Alzheimer neurofibrillary tangles. A retrospective study was based on unselected consecutive autopsy findings on the brains of 301 patients aged 65 years or older examined at the Institute of Pathology, Basel. Brains were investigated(More)
Continuous 72-h polygraphic recordings were carried out in 30 hospitalized, mostly severely demented patients and 14 nondemented control patients. Mean age was greater than 80 years in both groups. In the dementia group, the diagnoses were senile dementia Alzheimer type (n = 16), multi-infarct dementia (n = 8), and mixed or undefined dementia (MIX) (n = 6).(More)
Polygraphic recordings of wake and sleep were performed on 10 partly bed-ridden, severely deteriorated patients with senile dementia. Compared with healthy elderly persons these subjects showed less SWS (slow wave sleep, characterized by high amplitude, slow EEG waves), less REM sleep (rapid eye movement sleep, usually accompanied by dream activity) and(More)
