Time flies faster in epilepsy Open
People with epilepsy have a significantly reduced life expectancy and an increased burden of age-related comorbidities, raising the possibility that epilepsy accelerates biological aging. Seizures trigger molecular and cellular hallmarks o…

Seizure outcomes following epilepsy surgery in pediatric and young adult patients with high‐grade brain tumors: Results from a European survey Open
Objective Epilepsy surgery is a standard treatment for drug‐resistant epilepsy, resulting in seizure freedom in a significant number of cases. Although frequently performed for low‐grade brain tumors, it is rarely considered for high‐grade…

Outcome of Epilepsy Surgery in MRI-Negative Patients Without Histopathologic Abnormalities in the Resected Tissue Open
This study shows that seizure freedom can be reached in 40% of nonlesional patients with both normal MRI and histopathology findings. In particular, nonlesional temporal lobe epilepsy should be regarded as a relatively favorable group, wit…

Safety and Efficacy of Preoperative Embolization in Giant Intracranial Meningiomas Compared with Resection Surgery Alone Open
Background: Endovascular embolization of intracranial meningiomas is commonly performed as an adjunct to surgical resection and may reduce intraoperative blood loss and surgical time. However, it remains unclear whether preoperative emboli…

Brain expression profiles of two <i>SCN1A</i> antisense RNAs in children and adolescents with epilepsy Open
Objective Heterozygous mutations within the voltage-gated sodium channel α subunit ( SCN1A ) are responsible for the majority of cases of Dravet syndrome (DS), a severe developmental and epileptic encephalopathy. Development of novel thera…

Ganglioglioma with adverse clinical outcome and atypical histopathological features were defined by alterations in PTPN11/KRAS/NF1 and other RAS-/MAP-Kinase pathway genes Open
Exome-wide sequencing studies recently described PTPN11 as a novel brain somatic epilepsy gene. In contrast, germline mutations of PTPN11 are known to cause Noonan syndrome, a multisystem disorder characterized by abnormal facial features,…

A deep learning-based histopathology classifier for Focal Cortical Dysplasia Open
A light microscopy-based histopathology diagnosis of human brain specimens obtained from epilepsy surgery remains the gold standard to confirm the underlying cause of a patient’s focal epilepsy and further inform postsurgical patient manag…

DNA methylation-based classification of malformations of cortical development in the human brain Open
Malformations of cortical development (MCD) comprise a broad spectrum of structural brain lesions frequently associated with epilepsy. Disease definition and diagnosis remain challenging and are often prone to arbitrary judgment. Molecular…

Correlates of intellectual development before and after hemispherotomy: an analysis of 75 children and adolescents Open
This study describes the intellectual development of 75 children and adolescents who underwent hemispherotomy. Furthermore, we aimed to reveal predicting factors on pre- and postsurgical development with a focus on the role of aetiology. W…

Mosaic trisomy of chromosome 1q in human brain tissue associates with unilateral polymicrogyria, very early-onset focal epilepsy, and severe developmental delay Open
Polymicrogyria (PMG) is a developmental cortical malformation characterized by an excess of small and frustrane gyration and abnormal cortical lamination. PMG frequently associates with seizures. The molecular pathomechanisms underlying PM…

Genomic <span>DNA</span> methylation distinguishes subtypes of human focal cortical dysplasia Open
Objectives Focal cortical dysplasia ( FCD ) is a major cause of drug‐resistant focal epilepsy in children, and the clinicopathological classification remains a challenging issue in daily practice. With the recent progress in DNA methylatio…

Neurologic phenotypes associated with <i>COL4A1</i> / <i>2</i> mutations Open
COL4A1/COL4A2 mutations typically cause a severe neurologic condition and a broader spectrum of milder phenotypes, in which epilepsy is the predominant feature. Early identification of patients carrying COL4A1/COL4A2 mutations may have imp…

Histopathological Findings in Brain Tissue Obtained during Epilepsy Surgery Open
In patients with drug-resistant focal epilepsy requiring surgery, hippocampal sclerosis was the most common histopathological diagnosis among adults, and focal cortical dysplasia was the most common diagnosis among children. Tumors were th…

Predicting hand function after hemidisconnection Open
Hemidisconnections (i.e. hemispherectomies or hemispherotomies) invariably lead to contralateral hemiparesis. Many patients with a pre-existing hemiparesis, however, experience no deterioration in motor functions, and some can still grasp …

Mild Malformation of Cortical Development with Oligodendroglial Hyperplasia in Frontal Lobe Epilepsy: A New Clinico‐Pathological Entity Open
The histopathological spectrum of human epileptogenic brain lesions is widespread including common and rare variants of cortical malformations. However, 2–26% of epilepsy surgery specimens are histopathologically classified as nonlesional.…
