Earlier work showed that in a group of women suffering from partial epilepsy, there is a decrease in seizure frequency during the luteal phase of the menstrual cycle. Moreover, iv progesterone infusions decrease the discharge frequency from penicillin epileptic foci in cats, when given in doses that reach plasma concentrations as observed during pregnancy.(More)
Eleven children with typical absence seizures were studied clinically and by repeated 24-h EEGs with portable cassette tape recorder before and during anticonvulsant treatment. The history, the observation of seizures and the amount of spike-and-wave activity (episodes greater than 3 sec) were studied in relation to the plasma levels. The EEG revealed(More)
Sixteen patients with drug-resistant complex partial epilepsy were, during preoperative investigations for surgical treatment, subjected to intravenous methohexital and amobarbital EEG activation tests. The interictal epileptic spike discharges were visually counted on the seizure-generating side and compared with those found in the contralateral(More)
Twenty-four consecutive patients with familial amyloidosis with polyneuropathy (type 1), who were at different stages of the disease were investigated. The purpose was to report the electrophysiological features and to compare them with those found in other generalized neuropathies; 12 cases were familiar and 12 cases were sporadic. The diagnosis was(More)
Aicardi syndrome has been defined by the triad of agenesis of the corpus callosum, early seizure onset and lacunar chorioretinopathy. In a nation-wide survey a total of 18 Swedish cases were found. Fourteen girls were re-examined by one of the authors at the ages of 1-27 years. One was seizure free following epilepsy surgery operation, 13 were drug(More)
In a nation-wide survey of Aicardi syndrome, defined as the onset of epilepsy in the first six months of life, agenesis of the corpus callosum (partial or total) and lacunar chorioretinopathy, 18 patients, all girls, born between 1975 and 2002 were identified in Sweden. Fifteen were definite cases and three were regarded as probable, since they only(More)
Adult persons, 17 years old or older, with newly diagnosed (incident) epileptic seizures were prospectively identified in a community-based study. Electroencephalographic (EEG) recordings when awake and/or during sleep were performed in 103 persons (96.3%). Epileptiform activity was recorded during wakefulness in 18 of 101 persons (18%) and during sleep in(More)
The Cavitron ultrasonic surgical aspirator (CUSA) was used in a patient with an acoustic nerve tumour. After surgery she presented unilateral palsies of several cranial nerves. The nerve injuries were most likely induced by ultrasonic energy transmitted from the CUSA via the petrous bone. We suggest that when the CUSA is used in such operations care should(More)
Potentials from the sensory root of the trigeminal nerve in the cerebello-pontine angle, evoked by electrical stimulation of the different trigeminal divisions, were recorded during neurosurgical operations. Two components of the compound action potential could be distinguished: one early with large amplitude and one late with small amplitude. It is(More)
