Eslicarbazepine Acetate as Adjunctive Therapy for Primary Generalized Tonic-Clonic Seizures in Adults: A Prospective Observational Study.

Background: Eslicarbazepine acetate (ESL), a novel sodium channel blocker, is approved for mono and adjunctive treatment of partial epileptic seizures with or without secondary generalization. Its efficacy in primary generalized seizures has not yet been evaluated.

Objective: To evaluate the efficacy and safety of ESL in primary generalized tonic-clonic seizures (PGTCS) in an observational study.

Efficacy and safety of antiseizure medication in post-stroke epilepsy.

Background: Specific antiseizure medications (ASM) would improve the outcome in post-stroke epilepsy (PSE). The aim of this multicenter observational study was to compare different antiseizure monotherapies in PSE.

Methods: We collected the data from 207 patients with PSE who did not change their initial antiseizure monotherapy during the period of 12 months.

Holter-electrocardiogram-monitoring in patients with acute ischaemic stroke (Find-AF): an open-label randomised controlled trial.

Background: Atrial fibrillation is a major risk factor for recurrent ischaemic stroke, but often remains undiagnosed in patients who have had an acute ischaemic stroke. Enhanced and prolonged Holter-electrocardiogram-monitoring might increase detection of atrial fibrillation. We therefore investigated whether enhanced and prolonged rhythm monitoring was better for detection of atrial fibrillation than standard care procedures in patients with acute ischaemic stroke.

Hereditary spastic paraplegia: Clinicogenetic lessons from 608 patients.

Objective: Hereditary spastic paraplegias (HSPs) are genetically driven disorders with the hallmark of progressive spastic gait disturbance. To investigate the phenotypic spectrum, prognostic factors, and genotype-specific differences, we analyzed baseline data from a continuous, prospective cohort.

Methods: We recruited 608 HSP cases from 519 families of mostly German origin.

The spectrum of KIAA0196 variants, and characterization of a murine knockout: implications for the mutational mechanism in hereditary spastic paraplegia type SPG8.

Background: The hereditary spastic paraplegias (HSPs) are rare neurodegenerative gait disorders which are genetically highly heterogeneous. For each single form, eventual consideration of therapeutic strategies requires an understanding of the mechanism by which mutations confer pathogenicity. SPG8 is a dominantly inherited HSP, and associated with rather early onset and rapid progression.

AP5Z1/SPG48 frequency in autosomal recessive and sporadic spastic paraplegia.

Hereditary spastic paraplegias (HSP) constitute a rare and highly heterogeneous group of neurodegenerative disorders, defined clinically by progressive lower limb spasticity and pyramidal weakness. Autosomal recessive HSP as well as sporadic cases present a significant diagnostic challenge. Mutations in AP5Z1, a gene playing a role in intracellular membrane trafficking, have been recently reported to be associated with spastic paraplegia type 48 (SPG48).

A high-throughput resequencing microarray for autosomal dominant spastic paraplegia genes.

Hereditary spastic paraplegias (HSP) are a heterogeneous group of neurological disorders. Insidiously progressive spastic weakness of the lower extremities is the common criterion in all forms described. Clinically, HSP is differentiated into pure (uncomplicated) and complex (complicated) forms.

Diagnostic accuracy of plasma glial fibrillary acidic protein for differentiating intracerebral hemorrhage and cerebral ischemia in patients with symptoms of acute stroke.

Background: Glial fibrillary acidic protein (GFAP) is a biomarker candidate indicative of intracerebral hemorrhage (ICH) in patients with symptoms of acute stroke. GFAP is released rapidly in the presence of expanding intracerebral bleeding, whereas a more gradual release occurs in ischemic stroke. In this study the diagnostic accuracy of plasma GFAP was determined in a prospective multicenter approach.

Sex differences in early carotid atherosclerosis (from the community-based Gutenberg-Heart Study).

The objectives of this study were to describe gender differences in intima-media thickness (IMT) in a community-based population study and to define normal IMT values for healthy men and women. In total, 4,814 participants (aged 35 to 74 years; 2,433 men, 2,381 women) from the Gutenberg-Heart Study (GHS) were included. IMT was measured at both common carotid arteries using an edge detection system.

The safety and efficacy of add-on levetiracetam in elderly patients with focal epilepsy: a one-year observational study.

Purpose: The long-term safety and efficacy of levetiracetam (LEV) was evaluated as add-on therapy in focal epilepsy patients (n=491) aged at least 65 years who failed at least one monotherapy.

Methods: Patients (n=491) with focal epilepsy treated with at least one antiepileptic drug in monotherapy with insufficient seizure control were included in this prospective open-label study. The recommended LEV dose range was 1000-3000 mg per day.

A total of 220 patients with autosomal dominant spastic paraplegia do not display mutations in the SLC33A1 gene (SPG42).

The most frequent causes of autosomal dominant (AD) hereditary spastic paraplegias (HSP) (ADHSP) are mutations in the SPAST gene (SPG4 locus). However, roughly 60% of patients are negative for SPAST mutations, despite their family history being compatible with AD inheritance. A mutation in the gene for an acetyl-CoA transporter (SLC33A1) has recently been reported in one Chinese family to cause ADHSP-type SPG42.

Recruitment of motor cortex inhibition differentiates between generalized and focal epilepsy.

Intracortical disinhibitory mechanisms play a crucial role in epilepsy. Therefore, the recruitment of motor cortical excitability was evaluated to distinct between focal and generalized epileptic syndromes. Twenty-five untreated patients with epilepsy and 20 controls were enrolled.

Analysis of CYP7B1 in non-consanguineous cases of hereditary spastic paraplegia.

Hereditary spastic paraplegia (HSP) is a neurodegenerative condition defined clinically by lower limb spasticity and weakness. Homozygous mutations in CYP7B1 have been identified in several consanguineous families that represented HSP type 5 (SPG5), one of the many genetic forms of the disease. We used direct sequencing and multiplex ligation-dependent probe amplification to screen for CYP7B1 alterations in apparently sporadic HSP patients (n = 12) as well as index patients from non-consanguineous families with recessive (n = 8) and dominant (n = 8) transmission of HSP.

REEP1 mutation spectrum and genotype/phenotype correlation in hereditary spastic paraplegia type 31.

Mutations in the receptor expression enhancing protein 1 (REEP1) have recently been reported to cause autosomal dominant hereditary spastic paraplegia (HSP) type SPG31. In a large collaborative effort, we screened a sample of 535 unrelated HSP patients for REEP1 mutations and copy number variations. We identified 13 novel and 2 known REEP1 mutations in 16 familial and sporadic patients by direct sequencing analysis.

Screening of hereditary spastic paraplegia patients for alterations at NIPA1 mutational hotspots.

Mutations in NIPA1 cause hereditary spastic paraplegia type 6 (SPG6 HSP). Sequencing of the whole gene has revealed alterations of either of two nucleotides in eight of nine SPG6 HSP families reported to date. By analysing CpG methylation, we provide a mechanistic explanation for a mutational hotspot to underlie frequent alteration of one of these nucleotides.

Does the recruitment of excitation and inhibition in the motor cortex differ?

The level of excitability within the motor cortex can be described as a balance between excitation and inhibition, but it is unknown how well both processes correlate. To address this question, the authors measured motor cortical excitability and inhibition in healthy human subjects, comparing the recruitment of motor evoked potentials (MEPs) and the duration of the cortical silent period (CSP) after transcranial magnetic stimulation (TMS). Single-pulse "focal" TMS was applied at intensities varying between 90% and 200% of motor thresholds to the right motor cortex of 15 healthy volunteers.

Decreased dopamine D2/D3-receptor binding in temporal lobe epilepsy: an [18F]fallypride PET study.

Purpose: Although animal data are suggestive, evidence for an alteration of the extrastriatal dopaminergic system in human focal epilepsy is missing.

Methods: To quantify D2/D3-receptor density, we studied seven patients with temporal lobe epilepsy (TLE) and nine age-matched controls with positron emission tomography (PET) by using the high-affinity dopamine D2/D3-receptor ligand [18F]Fallypride ([18F]FP) suitable for imaging extrastriatal binding. TLE was defined by interictal and ictal video-EEG, magnetic resonance imaging (MRI), and [18F]fluorodeoxyglucose ([18F]FDG)-PET and was due to hippocampal sclerosis (HS), based on histology in all patients.

Antiepileptic drug use in nursing home residents: a cross-sectional, regional study.

The use of antiepileptic drugs (AED), their primary indication, comorbid conditions, and concomitant medications were collected from 565 nursing homes (NH) residents of six NH located around the city of Mainz, Germany representing 5.05% of all NH residents in the area. Data were collected from the electronic pharmacy files and by reviewing all available medical records.

Early onset autosomal dominant spastic paraplegia caused by novel mutations in SPG3A.

Hereditary spastic paraplegia (HSP) is a group of neurodegenerative disorders mainly characterized by progressive spasticity of the lower limbs. The major features of HSP are a marked phenotypic variability both among and within families and an extended genetic heterogeneity. More than 20 HSP loci and 10 spastic paraplegia genes (SPG) have been identified to date, including the genes responsible for the two most frequent forms of autosomal dominant spastic paraplegia (AD-HSP), encoding spastin (SPG4) and atlastin (SPG3A), respectively.
