Over the last few decades the ILAE classifications for seizures and epilepsies (ILAE-EC) have been updated repeatedly to reflect the substantial progress that has been made in diagnosis and understanding of the etiology of epilepsies and seizures and to correct some of the shortcomings of the terminology used by the original taxonomy from the 1980s. However, these proposals have not been universally accepted or used in routine clinical practice. During the same period, a separate classification known as the "Four-dimensional epilepsy classification" (4D-EC) was developed which includes a seizure classification based exclusively on ictal symptomatology, which has been tested and adapted over the years.

Objectives: Brivaracetam (BRV) is the latest approved antiepileptic drug and acts as a synaptic vesicle protein 2A ligand. The aim of the present study was to evaluate the efficacy and tolerability of BRV in the clinical setting.

Design: Retrospective, observational multicentre study.

Background: The relation between epilepsy and criminal acts has been debated for over a century. The general perception persists that epileptic seizures can be associated with violent behavior. Some studies have provided evidence for such an association; however, it remains uncertain whether it really exists.

Rationale: Cardiac arrest (CA) is a serious condition characterized by high mortality rates, even after initial successful resuscitation, mainly due to neurological damage. Whether brain-heart communication is associated with outcome after CA is unknown. Heartbeat-evoked brain potentials (HEPs) represent neurophysiological indicators of brain-heart communication.

Migraine is a primary episodic headache disorder that represents a substantial burden and disability worldwide. Its pathogenesis is multifactorial and remains hitherto poorly elucidated. An interesting but less-well-known association is that between migraine and gastrointestinal disorders.

Hemiplegic migraine is a rare and complex disease, characterized by migraine with a reversible motor aura. Hemiplegic migraine can be easily misdiagnosed at its first presentation with an atypical severe form of migraine, a stroke, multiple sclerosis, metabolic disorders, conversion disorder or an epilepsy. We present the case of a young 24-year-old male patient, who since the age of 4 years had been having multiple episodes of migraine associated with hemiparesis, paraesthesia, prolonged somnolence, aphasia and confusion.

During the last decades, only a few cases on the association between peripheral demyelinating diseases and multiple sclerosis (MS) have been reported. We describe the case of a young man who was initially diagnosed with Bell's palsy, and only after performing a brain MRI was the diagnosis of MS made. We review the literature and discuss some pitfalls which may lead to missing the diagnosis of MS.

For clinical trial design and for clinical practice, it is of importance to assess factors associated with placebo response in patients with refractory epilepsy. We determined factors associated with placebo response in 359 adult patients with refractory focal epilepsy participating in three randomized placebo-controlled trials of the new antiepileptic drug lacosamide. At the end of the randomized 12-week maintenance period, 81 (23%) of the 359 patients randomized to placebo achieved at least a 50% seizure reduction (responders) compared to baseline.

Purpose: Given serious concerns over the adverse effects of enzyme induction, modern nonenzyme-inducing antiepileptic drugs (AEDs) may be preferable, provided they have similar efficacy as enzyme-inducing AEDs. This is currently unclear.

Methods: Therefore, we performed a meta-analysis of the evidence to determine the placebo-corrected efficacy of adjunctive treatment with modern nonenzyme-inducing AEDs versus modern enzyme-inducing AEDs that are on the market for refractory focal epilepsy.

Although adjunctive treatment with modern antiepileptic drugs (AEDs) is standard care in refractory epilepsy, it is unclear how much of the effect can be attributed directly to the AEDs and how much to the beneficial changes seen with placebo. Therefore, we performed a systematic review and meta-analysis of the evidence to determine the placebo-corrected net efficacy of adjunctive treatment with modern AEDs on the market for refractory epilepsy. Of 317 potentially eligible articles reviewed in full text, 124 (39%) fulfilled eligibility criteria.

Article Synopsis
  • - A patient experienced decreased vision while on topiramate (TPM) for epilepsy, leading to an ophthalmological exam that indicated maculopathy.
  • - After discontinuing TPM, the patient's vision did not show significant improvement over six months.
  • - The authors speculate that TPM may have caused maculopathy, similar to how vigabatrin can lead to retinal toxicity and lasting visual issues.

Purpose And Background: Clinical experience with intravenous levetiracetam (LEV IV) is still very limited, especially in elderly subjects. The primary objective of this retrospective observational study was to describe the efficacy and tolerability of LEV IV in older patients presenting with epileptic seizure emergencies.

Methods: Medical records of 14 older people treated with LEV IV were analysed retrospectively.

Objectives: We prospectively studied 26 (10 women) patients (age, 37.4 +/- 10.3 years) with different types of refractory focal epilepsy who received topiramate as adjunctive treatment.

Background: The diagnosis of nonconvulsive status epilepticus (NCSE) is particularly challenging in elderly patients. Confusion, personality change, dysphasia, subtle motor activity and nystagmus may be the only presenting signs.

Objective: To review current knowledge about NCSE with special focus on older people.

Background: Valproate (VPA) is an antiepileptic drug with a broad spectrum of efficacy. Although usually well-tolerated, it may have side-effects of which encephalopathy is one of the most serious.

Objective: To describe the clinical characteristics of valproate encephalopathy (VE) in five older patients with remote symptomatic seizures treated with rapid VPA loading.

Patients with epilepsy have a high prevalence of psychiatric comorbid disorders. Many comorbidities have a significant impact on the medical management and quality of life of these patients. The main psychiatric complications in epilepsy include depression, anxiety disorders, and psychosis.

The availability of new antiepileptic drugs (AEDs) has expanded the spectrum of medical treatment options in epilepsy. However, the development of ten new compounds (vigabatrin, felbamate, gabapentin, lamotrigine, topiramate, tiagabine, oxcarbazepine, levetiracetam, zonisamide, and pregabalin) has not changed the basic principles of epilepsy treatment. The choice of an AED depends upon seizure type or seizure syndrome, efficacy, safety, tolerability, patient age and gender, concomitant medication, and comorbid conditions.

Up to 50 or 60% of patients with chronic epilepsy have various mood disorders including depression and anxiety. Whereas the relationship between epilepsy and depression has received much attention, less is known about anxiety disorders. It is now recognized that anxiety can have a profound influence on the quality of life of patients with epilepsy.
