OBJECTIVE The principal MRI features of hippocampal sclerosis are volume loss and increased T2 weighted signal intensity. Minor and localised abnormalities may be overlooked without careful quantitation. Hippocampal T2 relaxation time (HT2) can be quantified, but previously has only been measured on a few thick coronal slices with interslice gaps. In this(More)
These guidelines apply to patients whose seizures have not been controlled by antiepileptic drugs and who are being evaluated for possible surgery. They are supplemental to the general ''Recommendations for Neuroimaging of Patients with Epilepsy. " 2. GOALS In individual patients undergoing presurgical evalua-a. Delineation of structural and functional(More)
1. PREAMBLE These guidelines are intended to apply to patients with a clear diagnosis of epilepsy. They have been specifically formulated for the management of newly diagnosed patients and those with chronic epilepsy who have not been fully evaluated. They are not designed for full investigation of patients for possible surgical treatment. 2. AIMS AND(More)
Malformations of cortical development (MCD) are a common etiology for epilepsy. Laminar heterotopia, bilateral subependymal heterotopia, and lissencephaly have a genetic basis. No gene mutations have yet been identified in patients with focal cortical dysplasias. The aim of this study was to use quantitative morphometric tools to determine if there were(More)
On neuropathological investigation of eight cases with primary generalized epilepsy, none showed elective parenchymal necrosis, which is regarded (qualitatively and topologically) as characteristic of epilepsy in classical neuropathology. In seven of the eight cases, however, marked microdysgenesis with varying regional distribution was found. These(More)
Developmental disturbance of the brain as a factor in the causation of epilepsies has been suspected for a long time. An increase of nerve cells in the stratum moleculare, which is qualitatively observed in primary generalized epilepsy, is thought to be an indicator for slight maldevelopment. In this morphometric study, the neuron density of layer I in the(More)
The purpose of this study was to examine the incidence of patients with NES vs. NES and concomitant epilepsy in an epilepsy centre and to present a diagnostic algorithm. We collected and reviewed the data of 322 patients consecutively referred to the adult ward of our epilepsy centre in 1 year. The results of our study reveal that 44 (14%) of all patients(More)
The present study using the results of the postmortem examination of twenty-four children, who had infantile spasms (West-Syndrome), gives a view of the aetiology and course of the West-Syndrome. According to the time of occurrence of the lesions three groups could be established: one group of six cases with only embryofetal lesions, one group of ten cases(More)
OBJECTIVE To analyze, in patients with unilateral regional epilepsy, the influence of intracarotid amobarbital injection order on the level of recognition memory, with both injections performed within approximately half an hour, when the order was varied by a first injection into either the epileptogenic or the nonepileptogenic hemisphere. METHODS Of a(More)
