A previously described test for prosopo-affective agnosia (impairment of facial affect recognition) had been applied in 14 disoriented elderly patients with chronic organic brain syndrome, 14 fully oriented elderly patients with non-organic psychiatric disorders, and 14 normal volunteers. In this re-test study of 37 of the 42 subjects, after a six-month(More)
In a randomized blind study of 69 mental hospital patients over 50 years of age, a highly significant correlation was observed between the clinical symptoms of organic brain disease and the quantity of senile plaques found in the brains at autopsy. A stepwise multiple regression analysis indicated that independent significant predictors of the quantity of(More)
Energy metabolism was measured in children receiving long-term treatment with valproic acid. In 8 of 10 randomly selected subjects, the resting respiratory quotient was higher than in age- and sex-matched control subjects (0.91 +/- 0.01 vs 0.87 +/- 0.01; p < 0.05). A shift was observed in fuel consumption, and a significant reduction was found in the amount(More)
Impairment of the ability to recognize facially expressed emotions was studied in 14 chronically disoriented patients with chronic organic brain syndrome (CBS). This impairment was named prosopo-affective agnosia (PAA). A diagnostic requirement was relatively intact neurologic functioning in underlying perceptual-verbal-motor processing. A test was designed(More)
A rapid screening method is described for detecting amyloid angiopathy (AA) in the meningeal vessels with the use of thioflavin-S and fluorescence microscopy. AA was found most frequently in the brains of patients in whom senile degeneration of the Alzheimer type was complicated by severe arteriosclerosis, vascular hyalinosis and multiple infarcts (73(More)
Thirty-nine male patients (median age 61, range 19-92) from a neurologic ward were examined by a test for prosopo-affective agnosia (PAA), i.e., impairment in the recognition of facial affect (emotions) with no impairment in the recognition of facial features (PA, prosopo-agnosia). The scores for patients without hemispheric damage were close to those of(More)
Two experiments were conducted in which senile demented patients were shown pictures of happy, sad, and angry faces, and tested for their ability to recognize these emotional expressions. Their affect recognition was obviously impaired, as they tended to respond to the line or feature characteristics of the faces, instead of the affective meaning that was(More)
The performance of senile elderly persons and of young children was compared on an identical facial affect recognition test. The senile persons were disoriented with impaired recent memory. However, their neurological functioning in visual, perceptual, verbal, and motor processing required for the testing was intact. The children were divided into age(More)
