Comparative Study Clinical TrialMemory and intelligence outcome following surgery for intractable temporal lobe epilepsy: relationship to seizure outcome and evaluation using a customized neuropsychological battery.
The main objectives of this prospective study were to (1) assess memory and intelligence outcome following surgery for intractable temporal lobe epilepsy, (2) correlate this with seizure outcome and side of surgery, and (3) perform (1) and (2) using an indigenously developed battery customized to the Indian population. Prior to use in our epilepsy surgery program, the test-retest and interexaminer variance reliability of this battery had been established in both normal and cognitively compromised populations. The memory scores were overall rather than material-specific. ⋯ In contrast, patients who underwent left temporal surgery had no significant change in cognitive scores irrespective of seizure outcome. Cognitive improvement seems to occur in patients with good seizure outcome following nondominant temporal lobe surgery for intractable epilepsy with no evidence of pathology in the opposite temporal lobe. The same finding was not observed in patients undergoing left temporal surgery.

Comparative StudyAnxiety and depression in children with epilepsy and their mothers.
Children with epilepsy have high rates of depression and anxiety. The majority of studies concentrate on the children with epilepsy, but the emotional impact of epilepsy on family members is of clinical concern. In this cross-sectional study we aimed to examine the association between epilepsy in childhood and adolescence, and anxiety and depression in these patients and their mothers. ⋯ These results support findings from previous studies that children and adolescents with epilepsy have a higher frequency of depressive but not anxiety symptoms than the general population of healthy children and that this is independent of their mothers' symptoms.

Comparative StudyEffects of antiepileptic drugs on working memory as assessed by spatial alternation performance in rats.
Patients with epilepsy can have impaired cognitive abilities. Many factors contribute to this impairment, including the adverse effects of antiepileptic drugs (AEDs). However, there are few systematic data on the effects of AEDs on specific cognitive domains, such as working memory. ⋯ In contrast, ethosuximide significantly disrupted working memory. The disruptions produced by triazolam and phenobarbital were similar in magnitude to the effects of the muscarinic antagonist scopolamine. The present results indicate that AEDs can disrupt working memory, but there are differences among AEDs in the magnitude of the disruption that do not appear to be correlated with mechanism of action.

Biography Historical ArticleDictator Perpetuus: Julius Caesar--did he have seizures? If so, what was the etiology?
The "Dictator Perpetuus" of the Roman Empire, the great Julius Caesar, was not the one for whom the well-known cesarean operation was named; instead, this term is derived from a Latin word meaning "to cut." Caesar likely had epilepsy on the basis of four attacks that were probably complex partial seizures: (1) while listening to an oration by Cicero, (2) in the Senate while being offered the Emperor's Crown, and in military campaigns, (3) near Thapsus (North Africa) and (4) Corduba (Spain). Also, it is possible that he had absence attacks as a child and as a teenager. ⋯ The etiology of these seizures in this Julio-Claudian family was most likely through inheritance, with the possibility of sudden unexpected death in epilepsy (SUDEP) in his great grandfather and also his father. Our best evidence comes from the ancient sources of Suetonius, Plutarch, Pliny, and Appianus.

ReviewWhat is the evidence that oxcarbazepine and carbamazepine are distinctly different antiepileptic drugs?
Oxcarbazepine (OXC, Trileptal) is a modern antiepileptic drug (AED) used as both monotherapy and adjunctive therapy for the treatment of partial seizures with or without secondary generalization in adults and children above 4 years (USA) or 6 years (Europe) of age. Although OXC has been developed through structural variation of carbamazepine (CBZ) with the intent to avoid metabolites causing side effects, significant differences have emerged between the two drugs. The mechanism of action of OXC involves mainly blockade of sodium currents but differs from CBZ by modulating different types of calcium channels. ⋯ This constitutes compelling clinical evidence that OXC and CBZ are distinctly different medications. From postmarketing experience in over 1,000,000 patient years, OXC had an advantageous risk-benefit balance also in comparison to other new AEDs. OXC should be preferred over CBZ and other older AEDs because of its proven efficacy and excellent side effect profile in children, adolescents, and adults with partial seizures.
