Because seizures originate from different pathological substrates, the question arises of whether distinct or similar mechanisms underlie seizure generation across different pathologies. Better defining intracranial electroencephalographic morphological patterns at seizure-onset could improve the understanding of such mechanisms. To this end, we(More)
With almost 100 years of clinical experience, antiepileptic drugs (AEDs) remain the mainstay of epilepsy treatment. They suppress epileptic seizures by acting on a variety of mechanisms and molecular targets involved in the regulation of neuronal excitability. These include inhibitory-GABAergic and excitatory-glutamatergic neurotransmission, as well as ion(More)
Growing evidence indicates that fast oscillations (>80 Hz) can be recorded interictally in the scalp EEG of patients with epilepsy, and that they may point to the seizure-onset zone. However, mechanisms underpinning the emergence of scalp fast oscillations, and whether they differ from those of interictal epileptic discharges (IEDs), are yet to be(More)
Members of the human herpesviridae family are candidates for representing the macroenvironmental factors associated with multiple sclerosis (MS) pathogenesis. Real-time PCR was used to search for DNA of herpes simplex virus type-1/-2, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus (EBV), human herpesvirus 6 type A/B in paired cerebrospinal(More)
BACKGROUND Adverse effects (AEs) of antiepileptic drugs (AEDs) are a major impediment to optimal dosing for seizure control. Better understanding of clinical properties of AEs is a prerequisite for systematic research of their neurobiological underpinnings. This study aimed to define specific patterns of AE occurrence and determine their clinical relevance(More)
OBJECTIVE Adverse effects (AEs) are a major concern when starting antiepileptic drug (AED) treatment. This study quantified the extent to which AE reporting in people with new-onset seizures started on AEDs is attributable to the medication per se, and investigated variables contributing to AE reporting. METHODS We pooled data from 2 large prospective(More)
Epilepsy is a chronic disorder with complex effects on social, vocational, physical, and psychological well-being. Patient-oriented research has demonstrated that recurrent seizures have a strong adverse effect on health-related quality of life, but also that seizure rate in persons with pharmacoresistant epilepsy has only a modest correlation with quality(More)
In a recent meta-analysis of 38 double-blind randomized controlled trials (RCTs) comparing pregabalin (PGB) to placebo, we found 20 adverse events (AEs) to be significantly associated with PGB treatment. In the present study, we evaluated whether the incidence of these 20 AEs differs across distinct disorders in which PGB was investigated. Among the 38(More)
OBJECTIVE Although a clear correlation has been observed between high-frequency oscillations (HFOs) and the seizure-onset zone in distinct lesions, the role of the underlying pathologic substrates in the generation of HFOs is not well established. We aimed to investigate HFO correlates of different pathologic substrates in patients with drug-resistant(More)
