Antiepileptic Drug Treatment (antiepileptic + drug_treatment)
Selected AbstractsSturge,Weber syndrome and paroxysmal hemiparesis: epilepsy or ischaemia?DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 11 2004Floor E Jansen MD Transient neurological deficits experienced by patients with Sturge,Weber syndrome can be caused by epilepsy, or may result from temporary ischaemia of the cortex underlying the vascular malformation. To show the difficulty in distinguishing seizures from ischaemic symptoms, two male children with episodes of acute unilateral weakness are presented here as well as a review of the literature. The first child presented at 2 years of age with a sudden increase in his pre-existing right hemiparesis accompanied by screaming. Ictal epileptiform activity was recorded at the moment of the attack, and subsequent seizures were controlled by adjustment of antiepileptic drug treatment. The second child presented at 4 years of age with attacks of vomiting and a coinciding increase in the pre-existing paresis of the left leg. Electroencephalogram (EEG) recording did not show ictal epileptiform activity. The origin was presumed to be vascular. Treatment with aspirin led to control of these transient ischaemic attacks. Ictal EEG is needed to differentiate between an epileptic and an ischaemic origin of transient focal deficit. Treatment with aspirin should be considered if an ischaemic origin cannot be excluded. [source] Cardiac function and antiepileptic drug treatment in the elderly: A comparison between lamotrigine and sustained-release carbamazepineEPILEPSIA, Issue 8 2009Erik Saetre Summary Purpose:, To investigate the comparative effects of carbamazepine (CBZ) and lamotrigine (LTG) on electrocardiography (ECG) parameters in elderly patients with newly diagnosed epilepsy. Methods:,, The study was conducted in the Norwegian subcohort (n = 108) of an international randomized double-blind 40-week trial, which compared the efficacy and tolerability of LTG and sustained-release CBZ in patients aged 65 and older with newly diagnosed epilepsy. Target maintenance doses were 400 mg/day for CBZ and 100 mg/day for LTG, with adjustments based on clinical response. Patients with significant unpaced atrioventricular (AV) conduction defect were excluded. Resting 12-lead ECG recordings were made under standardized conditions at pretreatment (baseline) and at the 40-week study visit (treatment visit). Changes in QRS interval (primary endpoint), heart rate (HR), PQ, and QTc (HR-corrected QT) intervals were assessed and compared between groups. Results:, Of the 108 patients randomized, 33 discontinued prematurely because of adverse events (n = 24, none of which was cardiac) or other reasons (n = 9), and 15 were nonevaluable due to incomplete ECG data. None of the assessed ECG parameters differed significantly between groups at baseline. No significant ECG changes were recorded between baseline and treatment visit for QRS duration and QTc intervals, whereas HR fell and PQ intervals increased slightly on both treatments. However, there were no differences between groups in changes from baseline to treatment visit. There were no significant relationships between individual ECG changes and serum drug concentrations, except for QTc intervals, which decreased slightly with increasing CBZ concentrations. The proportion of patients with ECG parameters outside the normal range at treatment visit was similar to that recorded at baseline. Discussion:, Clinically significant ECG changes are not common during treatment with CBZ or LTG in elderly patients with no preexisting significant AV conduction defects. [source] History of the ketogenic dietEPILEPSIA, Issue 2008James W. Wheless Summary Fasting and other dietary regimens have been used to treat epilepsy since at least 500 BC. To mimic the metabolism of fasting, the ketogenic diet (KD) was introduced by modern physicians as a treatment for epilepsy in the 1920s. For two decades this therapy was widely used, but with the modern era of antiepileptic drug treatment its use declined dramatically. By the end of the twentieth century this therapy was available in only a small number of children's hospitals. Over the past 15 years, there has been an explosion in the use, and scientific interest in the KD. This review traces the history of one of the most effective treatments for childhood epilepsy. [source] Mortality in epilepsy in the first 11 to 14 years after diagnosis: Multivariate analysis of a long-term, prospective, population-based cohortANNALS OF NEUROLOGY, Issue 3 2001Samden D. Lhatoo MRCP The United Kingdom National General Practice Study of Epilepsy is a prospective, population-based study of newly diagnosed epilepsy. A cohort of 792 patients has now been followed for up to 14 years (median follow-up [25th, 75th percentiles] 11.8 years, range 10.6,11.7 years), a total of 11,400 person-years. These data are sufficient for a detailed analysis of mortality in this early phase of epilepsy. Over 70% of patients in this cohort have developed lasting remission from seizures, although the mortality rate in the long term was still twice that of the general population. The standardized mortality ratio (SMR), the number of observed deaths per number of expected deaths, was 2.1 (95% confidence interval [CI] = 1.8, 2.4). Patients with acute symptomatic epilepsy (SMR 3.0; 95% CI = 2.0, 4.3), remote symptomatic epilepsy (SMR 3.7; 95% CI = 2.9, 4.6), and epilepsy due to congenital neurological deficits (SMR 25; 95% CI = 5.1, 73.1) had significantly increased long-term mortality rates, whereas patients with idiopathic epilepsy did not (SMR 1.3; 95% CI = 0.9, 1.9). This increase in mortality rate was noted particularly in the first few years after diagnosis. Multivariate Cox regression and time-dependent co-variate analyses were utilized for the first time in a prospective study of mortality in epilepsy. The former showed that patients with generalized tonic-clonic seizures had an increased risk of mortality. The hazard ratio (HR), or risk of mortality in a particular group with a particular risk factor compared to another group without that particular risk factor, was 6.2 (95% CI = 1.4, 27.7; p = 0.049). Cerebrovascular disease (HR 2.4; 95% CI = 1.7, 3.4; p < 0.0001), central nervous system tumor (HR 12.0; 95% CI = 7.9, 18.2; p < 0.0001), alcohol (HR 2.9; 95% CI = 1.5, 5.7; p = 0.004), and congenital neurological deficits (HR 10.9; 95% CI = 3.2, 36.1; p = 0.003) as causes for epilepsy and older age at index seizure (HR 1.9; 95% CI = 1.7,2.0; p < 0.0001) were also associated with significantly increased mortality rates. These hazard ratios suggest that epilepsy due to congenital neurological deficits may carry almost the same risk of mortality as epilepsy due to central nervous system tumors and that epileptic seizures subsequent to alcohol abuse may carry almost the same risk of mortality as epilepsy due to cerebrovascular disease. The occurrence of one or more seizures before the index seizure (the seizure that led to the diagnosis of epilepsy and enrolment in the study) was associated with a significantly reduced mortality rate (HR 0.57; 95% CI = 0.42, 0.76; p = 0.00001). Time-dependent co-variate analysis was used to examine the influence of ongoing factors, such as seizure recurrence, remission, and antiepileptic drug use, on mortality rates in the cohort. Seizure recurrence (HR 1.30; 95% CI = 0.84, 2.01) and antiepileptic drug treatment (HR 0.97; 95% CI = 0.67, 1.38) did not influence mortality rate. There were only 5 epilepsy-related deaths (1 each of sudden unexpected death in epilepsy, status epilepticus, burns, drowning, and cervical fracture), suggesting that death directly due to epileptic seizures is uncommon in a population-based cohort with epilepsy.

Legros Objectives,,, (i) To describe the medical treatment of epilepsy in Belgium in 2006, (ii) to detect the presence or absence of consensus in epilepsy treatment and (iii) to analyze the evolution of the neurologists' opinion between 2003 and 2006. Materials and methods,,, In December 2006, 100 neurologists were interviewed with a structured questionnaire, based on ordinal four-point scales. The questionnaire contained questions on treatment choices in adult patients with epilepsy. The results of this survey were compared with results of a previous one done in 2003. Results,,, Initial monotherapy was the preferred treatment strategy. Valproate was first choice in idiopathic generalized epilepsy. Carbamazepine and oxcarbazepine were first choice in focal epilepsy with partial seizures. Valproate was also first choice in focal epilepsy with secondarily generalized seizures. New antiepileptic drugs were recommended in second line. However, in special treatment situations, they were considered first-line, e.g. lamotrigine in case of women in childbearing age. In comparison with 2003, there was a trend of using earlier the new antiepileptic drugs. Conclusions,,, In end 2006, carbamazepine, valproate and oxcarbazepine were considered to be first choice drugs, whereas other newer drugs, like lamotrigine, levetiracetam and topiramate were predominantly prescribed in second line.
