The authors report the surgical management of 32 patients with medically intractable seizures. In all cases the epileptiform focus present in the temporal region was demonstrated by electroencephalography. Our report was made up of 14 male patients and 18 female patients. Their ages ranged from 9 to 62 years. The material was divided into two groups. The(More)
We have analyzed 155 subjects with STAI (State-Trait Anxiety Inventory): 75 epileptic patients and 80 normal subjects used as a control group. A higher trait-anxiety score (chronic anxiety) than that of controls was found for the epileptic group. For the epileptic group higher levels of the A-trait occurred in patients with EEG abnormalities with left(More)
We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan) and non-lesional cases (i.e. without CT scan lesions), in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span), dichotic listening CV task and Central Auditory Test (SSI, PSI). The aim of this paper was to study the hemispheric(More)
Surgery of arteriovenous malformations (AVM) and of cavernous angiomas (cavernoma) in the majority of cases is indicated subsequently to episodes of bleeding. With the development of techniques for diagnosis and surgery for epilepsy of difficult control, indication for surgery of these vascular lesions has become greater. We present nine patients with(More)
The encephalopathy is characterized by an important arteriosclerotic involvement of the vessels of the cerebral white matter and a diffuse subcortical demyelination, sparing the cortex. The diagnosis is presently possible, ante mortem, by connecting the clinical picture with the CT scan findings, which are essential. Three cases with Binswanger(More)
Repeated electrical low intensity stimulation of various regions of the brain has been shown to induce epileptic seizure activity. This experimental model of epilepsy has been used in our laboratory in rats. Male rats, anaesthetized with nembutal (20 mg/kg, i.p.) and ketalar (60 mg/kg, i.p.) were implanted stereotaxically with electrodes in the dorsal(More)
This study concerns about brain electrical activity during auditory stimulation in 2 aphasic patients, one with classical (left hemisphere lesion) and another with cross aphasia (right hemisphere lesion). Both cases were submitted to dichotic listening test (consonant-vowel-consonant task) and music audition (gregorian chant), during brain mapping(More)
A retrospective study was performed on 34 patients with photosensitivity detected on the electroencephalogram. This group was compared to an aleatory sample, with 218 patients. The objectives were to evaluate the photosensitivity and: type of epilepsy, age of onset of seizures, sex ratio, frequency of seizures, and family history.
The performance in visual verbal and non-verbal attentional tests was studied in 14 male and 18 female control subjects and 33 patients with cryptogenic partial epilepsy. The epileptic group was formed of 17 men and 16 women with no evidence of brain damage in CT scan examinations. Interictal epileptiform activity was observed only unilaterally, either in(More)
