In ten Parkinsonians who developed dose-related response fluctuations under long-term levodopa therapy, regional cerebral blood flow (rCBF) and plasma levodopa levels were measured simultaneously, once during an "off" phase and again at an "on" stage of clinical benefit induced by a single oral dose of levodopa. Although plasma levodopa increased threefold(More)
The ability to identify and recognize emotional materials was studied in 10 male alcoholic Korsakoff patients, 27 male non-Korsakoff alcoholics, and 31 male nonalcoholic controls, across a wide age range (23 to 77 years). Stimulus materials were presented in two sensory modalities; the materials were photographs of faces expressing one of four emotions(More)
In Parkinson's disease, there is high prevalence of dementia, reduction of the regional cerebral blood flow (rCBF), and neuronal loss and Alzheimer-like pathologic changes in cerebral cortex. Since rCBF is also decreased in Alzheimer's dementia, it is theoretically possible that both decreases in rCBF and cognitive impairment in parkinsonians are caused by(More)
Regional cerebral blood flow was measured in 14 patients with Down's syndrome, in 46 patients with Alzheimer's disease and senile dementia of the Alzheimer type, and in 114 age-matched controls, using the xenon 133 inhalation technique. Cerebral blood flow was reduced in 13 of 14 Down's patients by a mean of 16.8 +/- 2.5% from expected age-matched normal(More)
Twenty-six patients with recently diagnosed leptomeningeal metastases underwent multiple diagnostic procedures in order to assess possible cerebral parenchymal involvement. Pretreatment studies included detailed neurological examination, computed tomographic scan, electroencephalogram, neuropsychological assessment, psychiatric evaluation, and measurement(More)
