ABSTRACT

This paper proposes therapeutic guidelines for the management of some epileptic syndromes in infants, children, and adolescents, based on available medical literature and clinical practice in the French Community of Belgium. The guidelines address both epileptic encephalopathies (West syndrome, Lennox-Gastaut syndrome, and Dravet syndrome) and idiopathic epilepsies (typical absence seizures, epilepsy with centro-temporal spikes and juvenile myoclonic epilepsy).

ABSTRACT

The authors propose to define the epileptic syndromes with continuous spikes and waves during slow sleep (CSWS) as a cognitive or behavioral impairment acquired during childhood, associated with a strong activation of the interictal epileptiform discharges during NREM sleep--whatever focal or generalized--and not related to another factor than the presence of CSWS. The type of syndrome will be defined according to the neurological and neuropsychological deficit. These syndromes have to be classified among the localization-related epileptic syndromes. Some cases are idiopathic and others are symptomatic. Guidelines for work-up and treatment are proposed.

ABSTRACT

In many circumstances antiepileptic drugs are used in patients who have never presented any clinical epileptic seizures. These substances are administered on the assumption of a potential risk for the patients of developing acute or delayed chronic seizures after brain injuries such as trauma, stroke, hemorrages or even neurosurgical interventions. The aim of this paper is to propose therapeutic guidelines for the management of this prophylactic attitude in epilepsy based on basic research and clinical practice in the French community in Belgium. We will distinguish between the prevention of acute (early onset-provoked) seizures and a delayed truly post-lesional (unprovoked) epilepsy. Some therapeutic goals can be achieved under the former circumstances whereas in the latter situation we all agree for the absence of any coherent antiepileptic prophylactic behaviour.

ABSTRACT

Epilepsy and psychiatric diseases are frequent comorbidities. Psychoses in patients with epilepsy have special physiopathology and several clinical presentations and prognoses. Their treatments are also specific, according to the specific diagnosis. This paper represents the summary of a consensus meeting held in November 2003 by a Belgian French-speaking group of neurologists, neuropediatricians and psychiatrists and proposes guidelines for the recognition and treatment of those entities.

ABSTRACT

All antiepileptic medications have potential side-effects. Some are rather specific like diplopia for carbamazepin or lamotrigin, whereas others are not, like fatigue or unsteadiness. Most are dose-related and can therefore be alleviated by dose reduction (e.g. somnolence or tremor) but a few are idiosyncratic (e.g. rash) and require cessation of the causative agent. Some can be detected and followed-up on a clinical basis but others necessitate specific examinations.

ABSTRACT

Approximately 20% of people with epilepsy are of childbearing potential and about 3 to 5 births per thousand will be to women with epilepsy. Both epilepsy and antiepileptic drugs can cause specific problems in women and embryos (less than 8 weeks of gestational age) or foetuses (more than 8 weeks of gestational age). The aim of this paper is to discuss therapeutic issues for the management of women with epilepsy: initiation of antiepileptic therapy, contraception, pregnancy, breast feeding and menopause. Some fertility issues are also discussed.

ABSTRACT

The choice of treatment of newly diagnosed epilepsy involves many factors such as age, sex, life style, general health and concomitant medication. The seizure type, syndrome, and the pharmacology, efficacy and safety of the antiepileptic drugs (AEDs) should also be considered. Some of the new AEDs appear to provide at least equivalent efficacy with better tolerability. Some of these drugs have the potential to become drugs of first choice in newly diagnosed epilepsy. At the present time, we also must consider the criteria of reimbursement of these drugs. In this paper, we try to describe common and practical strategies to start a treatment of newly diagnosed epilepsy.

ABSTRACT

Medical treatment of epilepsy has evolved during the last ten years. The "Epileptic Syndrome Classification" established in 1989 and new antiepileptic drugs account for these changes. This article recalls the principal rules of medical treatment of epilepsy and reviews new antiepileptic drugs available in Belgium.

ABSTRACT

We report a 44-year-old female patient without any familial history of dementia presenting with increasing disturbances in behaviour and language followed by a progressive cognitive deterioration. Neuropsychological evaluation revealed a significant impairment on frontal lobe tests. A brain PET scan disclosed a severe frontal hypometabolism. The tentative diagnosis of frontotemporal dementia was made. Her condition rapidly worsened and she died 2 years after the beginning of her disease. Gross examination of the brain showed a selective symmetrical atrophy of both frontal and anterior part of the temporal lobes. Microscopical examination revealed severe neuronal loss in the frontal and anterior temporal cortex associated with gliosis and microvascular spongiosis in the superficial cortical layers in the absence of any specific neuronal or glial inclusions. These neuropathological findings were consistent with the diagnosis of dementia lacking distinctive histology. We discuss the nosology of the frontotemporal dementias, the diagnostic value of PET scan, the recent genetical developments which strongly support the pathogenic role of tau and we emphasize the importance of immunohistochemical examination for a definite neuropathological diagnosis.

ABSTRACT

We investigated statistical parametric mapping (SPM) use for positron emission tomography (PET) with [(18)F]fluorodeoxyglucose (FDG) data analysis in mesial temporal lobe epilepsy. The study involved 14 patients with temporal lobe epilepsy ultimately treated by anterior temporal lobectomy. Surgical outcome in terms of seizure control was favorable in 12 patients. Two different SPM approaches were designed to analyze each FDG-PET scan: a direct comparison with a control group (n = 27) and a search for significant interhemispheric asymmetry considering the asymmetry existing in the control group. Statistical inference was performed, first, without correction for multiple comparisons (making the hypothesis of temporal hypometabolism) and, second, after correction for multiple comparisons. Search for temporal interhemispheric asymmetry under the hypothesis of temporal hypometabolism was the most reliable SPM approach: hypometabolism was identified on the side chosen for resection in most cases (sensitivity, 71%; specificity, 100%) and was predictive of favorable postsurgical outcome in 90% of the patients. There was no false-positive result within the control group using this approach. After correction for multiple comparisons, SPM also identified in some patients temporal hypermetabolic areas as well as extratemporal cortical and subcortical hypometabolic areas on the side of resection but also on the contralateral side. In a further step, SPM was used for a group analysis of patients with favorable outcome after reversing scans when needed to set an identical lateralization in all patients. This analysis identified multiple ipsilateral temporal and extratemporal hypometabolic regions; when temporal metabolic changes were specifically assessed, the contralateral mesiotemporal region was found hypermetabolic, possibly as a manifestation of compensatory mechanisms in the presence of a unilateral epileptogenic lesion.

ABSTRACT

Epilepsy and non-localized brain dysfunction have been invoked, among others, as underlying factors in borderline personality disorder. We have recorded 58 electroencephalograms in 20 borderline patients, first after complete drug washout and then under carbamazepine or placebo double-blind treatment. Taking into account only definite abnormal tracings, we found a 40% incidence of abnormal diffuse slow activity. No patient disclosed focal or epileptiform EEG features. Carbamazepine did not appear to modify the electroencephalogram.

ABSTRACT

Recently, an immunocytochemical method using glutaraldehyde fixation and an antiserum developed against a GABA--glutaraldehyde--protein conjugate has permitted direct visualization of GABAergic structures in the brains of perfused animals. This paper reports a successful use of this technique on human temporal cortex fixed by immersion. The cerebral tissue was obtained from patients operated for focal epilepsy. GABA-positive somata, fibres and terminals are observed in all layers of the temporal cortex. Terminals are particularly abundant in the superficial portion of layer I and in layers II, III and IV. Dense plexuses of fibres are located in layers II, III, IV and VI and in the underlying white matter. Somata are found in all cortical layers and in the underlying white matter; they are round, oval, fusiform or triangular and exhibit a multipolar, bitufted or bipolar dendritic pattern. This technique for the visualization of GABAergic structures in the human brain may allow a better understanding of the pathogeny of epilepsy in which the GABAergic transmission has been implicated.

ABSTRACT

Myelography is usually normal in radiation myelopathy. Occasionally it may show an enlarged spinal cord with block or a spinal cord of reduced size. It is assumed that the enlargement of the spinal cord is transitory, occurs in early stages of radiation myelopathy and is due to oedema, whereas atrophy is seen in later stages of the disease. This assumption however has not been clearly established by sequential radiological examinations. The purpose of this case report is to demonstrate such changes by repeated X-ray investigations.
