There is little literature on a possible link between the use of antiepileptic drugs (AEDs) and the occurrence of suicidal ideation. Nevertheless, its occurrence needs to be promptly recognized because it may trigger suicidal attempts. ⋯ All cases occurred in the context of a mood disorder presenting early during LEV therapy. Psychopathological characteristics of suicidal ideation were consistent in all subjects and similar to some features that are described as typical of the so-called interictal dysphoric disorder of epilepsy.

Isobolographic analysis of interactions between remacemide and conventional antiepileptic drugs in the mouse model of maximal electroshock.
Using the mouse maximal electroshock-induced seizure model, indicative of tonic-clonic seizures in humans, the present study was aimed at characterizing the interaction between remacemide and valproate, carbamazepine, phenytoin, and phenobarbital. Isobolographic analysis indicated additive interactions between remacemide and valproate, carbamazepine, and phenytoin (for all fixed ratios of tested drugs: 1:3, 1:1, and 3:1). Additivity was also observed between remacemide and phenobarbital applied in proportions of 1:1 and 3:1. ⋯ In contrast, phenobarbital co-administration was associated with decreases in brain remacemide (27%) and desglycinyl-remacemide (9%) concentrations, whereas only remacemide concentrations (increased by 131%) were affected by carbamazepine co-administration. In conclusion, significant and desirable pharmacodynamic interactions were observed between remacemide and valproate, carbamazepine, phenytoin, and phenobarbital. However, the concurrent pharmacokinetic interactions associated with remacemide complicate these observations and do not make remacemide a good candidate for adjunctive treatment of epilepsy.

Randomized Controlled Trial Comparative Study Clinical TrialSlight improvement in mood and irritability after antiepileptic drug withdrawal: a controlled study in patients on monotherapy.
Most antiepileptic drugs (AEDs) are considered to have effects on mood and to be effective in a number of affective disorders. There are, however, conflicting reports in the literature with respect to the psychotropic properties of AEDs. Many of the studies have a number of methodological problems, and much uncertainty still exists regarding the behavioral and mood effects of AEDs. The aim of this study was to assess, in a randomized, double-blind, placebo-controlled study of seizure-free patients with epilepsy, the effect of withdrawal of AEDs in patients on monotherapy on measures of mood and behavior. ⋯ The results suggest that seizure-free patients with epilepsy on monotherapy can obtain a slight improvement in symptoms characteristic of depression and irritability if they discontinue treatment with AEDs. The described changes are limited, and the functional impact is of uncertain significance.

Levetiracetam in clinical practice: long-term experience in patients with refractory epilepsy referred to a tertiary epilepsy center.
For the treatment of patients with chronic refractory epilepsies, development of new antiepileptic drugs is crucial. Three regulatory trials have demonstrated that add-on levetiracetam is efficacious in patients with localization-related epilepsy. However, results from these highly controlled short-term clinical trials cannot simply be extrapolated to everyday clinical practice. Therefore, more information is needed about the long-term profile of a new antiepileptic drug in clinical practice. ⋯ Levetiracetam is a new antiepileptic drug that appears to be a useful add-on treatment in patients with refractory epilepsy. Its side effect profile is mild, with mood disorders being the most dominant adverse event.

Case ReportsFluctuating Kluver-Bucy syndrome in a child with epilepsy due to bilateral anterior temporal congenital malformations.
An 11-year-old boy with epilepsy due to congenital bilateral anterior temporal lobe malformations presented with fluctuating Kluver-Bucy syndrome (KBS). Since the age of 2, he had experienced clusters of three or four daily complex partial seizures over 2-3 days in a month, followed by a seizure-free interval of 3-4 weeks. During the seizure-free period, the patient exhibited hyperorality, sniffing, irritability alternating with placidity, anxiety, unsolicited sexual gestures, and unusual calmness after eating. ⋯ This is the first reported case of KBS due to congenital bitemporal malformations. Also, KBS behavior phenotype in this patient fluctuated, with escalation during the seizure-free period and remission induced by the monthly seizure cluster. This fluctuating pattern could represent forced normalization.
