Nonepileptic seizures (NES) are common and are often diagnosed at epilepsy centers by video-EEG recording of both spontaneous and suggestion-induced episodes, but no study has evaluated provocative testing in a general seizure population. We studied consecutive patients with a tentative diagnosis of epilepsy using saline provocation during video-EEG(More)
Previous studies have suggested that estrogen may have an effect on cognitive and emotional function in women. Studies in rodents and non-human primates have demonstrated the presence of estrogen receptors in brain, and that estrogen can affect behavior in animals. Estrogen administration to ovariectomized rats increases choline acetyltransferase activity(More)
We discuss four patients with the clinical diagnosis of basilar migraine and suspected coexisting epilepsy who were referred to our epilepsy center. Their symptoms suggested episodic dysfunction in the distribution of the basilar artery, followed by pulsating headache with nausea. Verbal unresponsiveness and sensory symptoms occurred in all four patients;(More)
Two cases of cystic brainstem schwannomas protruding into the fourth ventricle are described. Both patients presented with hemifacial spasm. While there is only one previous case report of an intraventricular brainstem schwannoma, there has been no prior description in the literature of hemifacial spasm associated with such a tumor. The clinical,(More)
Multiple sclerosis (MS) has no significant effect on fertility, conception, fetal viability, and delivery. Exacerbations of MS decrease during pregnancy and increase significantly during the 3 months postpartum. Pregnancy does not increase the risk of brain tumors, but physiologic changes induced by pregnancy affect the diagnosis and biologic behavior of(More)
Selected dermatoglyphic variables were analyzed in 50 patients with presumed Alzheimer's disease (AD), 50 patients with dementia referable to other causes, and 100 control patients without known dementia matched for age, sex, and race. AD patients have a significantly increased frequency of ulnar loops on the fingertips, Simian creases on the palms, palmar(More)
Seven patients with AIDS-related cognitive and emotional deficits had neuropsychologic testing and then were treated with methylphenidate or dextroamphetamine in individualized doses. Three patients showed marked functional improvement and 5 of the 7 became more spontaneous, reactive, and animated. Additional neuropsychologic testing showed statistically(More)
This investigation reports pilot data on two points originally raised in the earliest reports of the efficacy of beta-blockers in akathisia: their potential utility in the akathisia of idiopathic Parkinson's disease and the possibility of determining a central vs. a peripheral site of action by comparing the time course of the effects of lipophilic and(More)
