Event-related potentials were recorded from 1221 sites in the medial, lateral and posterior aspects of the temporal lobe in 39 patients. Depth electrodes were implanted for about 4 days in order to localize seizure origin prior to surgical treatment. Subjects received an auditory discrimination task with target and non-target rare stimuli. In some cases,(More)
Six severe epileptic patients developed stuporous encephalopathy with marked cognitive impairment when topiramate (TPM) and sodium valproate (VPA) were coprescribed for five patients, and when monotherapy with TPM was introduced for one patient. In four patients, ammonaemia increased and then returned to normal after TPM or VPA withdrawal. This severe(More)
A patient with clinically complete cervical spinal cord transection developed rhythmic myoclonic movements of the trunk and lower limbs, demonstrating that, in man, such movements can be generated within the spinal cord itself when deprived of supraspinal control. Electromyographic (EMG) recordings used to define the features of the myoclonus, which had a(More)
Generic substitution is encouraged as a cost containment strategy for the management of health care resources. However, in epilepsy, the consequences of loss of symptom control are important, and antiepileptic drugs have narrow therapeutic indices. For this reason, generic substitution may be problematic, and certain health authorities have excluded(More)
PURPOSE Single photon emission computed tomography (SPECT) is used as an adjunctive method in preoperative localization of epileptic foci. In temporal lobe epilepsy (TLE), interictal hypoperfusion is observed in 60-70% of cases. Correlation with ictal EEG changes is observed in approximately 50-60% of cases. Relationships with interictal EEG have been(More)
PURPOSE The International League Against Epilepsy (ILAE) classification distinguishes medial and neocortical temporal lobe epilepsies. Among other criteria, this classification relies on the identification of two different electroclinical patterns, those of medial (limbic) and lateral (neocortical) temporal lobe seizures, depending on the structure(More)
OBJECTIVES There are circumstances in which partial seizures may be misdiagnosed as acute psychiatric disturbances. In particular, when fear is the prominent feature the patient may be considered for years as having panic attacks. Eight patients in whom fear was the main symptom of the seizures are reported on. Patients who had a proved lack of(More)
BACKGROUND Studies in animal models and epileptic patients have suggested that circuits of the basal ganglia may control epileptic seizures and that striatal dopaminergic transmission plays a key role in seizure interruption. Ring chromosome 20 (r[20]) epilepsy is a very homogenous type of epilepsy and is clinically characterized by long-lasting seizures(More)
