It has long been a matter of debate whether recovery from aphasia after left perisylvian lesions is mediated by the preserved left hemispheric language zones or by the homologous right hemisphere regions. Using PET, we investigated the short-term changes in the cortical network involved in language comprehension during recovery from aphasia. In 12(More)
The recently available ultrafiltration technique facilitates determination of the free drug serum concentration of several antiepileptic drugs. For this reason a reappraisal of the clinical significance of free level monitoring was thought necessary. In this study on 203 patients receiving carbamazepine monotherapy and 101 patients receiving valproic acid(More)
A total of 181 human immunodeficiency virus (HIV)-seropositive hemophiliacs and 28 hemophilic controls were evaluated by psychometric tests and by electroencephalogram (EEG). Patients were classified from stages 1-6 according to the immunological criteria of the Walter Reed staging system. Statistical analysis of psychometric data showed an effect of the(More)
Circadian modulation of seizure threshold is subjected to a multitude of periodical, aperiodical and stochastical influences. Epilepsies on the other hand influence the biological rhythms themselves. Epileptic seizures are activated during transient sleep stages. Nocturnal seizures lead to severe sleep disorders and therefore to hypersomnia. Partial and(More)
We report on 79 pregnancies in 66 female outpatients with epilepsy. An increase of seizure frequency was significantly more frequent in complex partial seizures than in grand mal seizures and in absences. The reason for these disparities are not clear. In most patients a raised frequency of seizures during pregnancy decreased again after delivery.(More)
Human immunodeficiency virus (HIV)-seropositive patients show involvement of the central and/or peripheral nervous system. We present here the results of electroencephalographic (EEG) findings in stage WR 1-5 HIV-seropositive hemophiliacs from a total of 184 who attended our clinic prior to October 1987.
In nine patients with suspected psychogenic seizures and in three patients with proven epileptic seizures HMPAO-SPECT was performed prior to and during seizure. In the patients with later on-proven psychogenic seizures no, or only slight, changes of regional cerebral blood flow were found. Patients with proven epilepsy revealed partly normal findings(More)
The anticonvulsant efficacy and side-effect liability of flunarizine (15 mg/day) was investigated in a randomized, double-blind, placebo-controlled, crossover design in 30 outpatients with drug-resistant complex partial seizures. Flunarizine or placebo was added to the preexisting medication and each patient was followed up for 10 months. At the end of the(More)
