OBJECTIVE: Neurofibromatosis type I (NF1), Tuberous sclerosis complex (TSC) and Sturge-Weber syndrome (SWS) are the most common neurocutaneous syndromes. The purpose of this study is to evaluate clinical neuroradiological manifestations patients diagnosed with NF1, TSC, SWS.MATERIAL AND METHODS: In our clinic, records 15 SWS were retrospectively reviewed between December 2017 May 2019. Clinical...

Ever since the implementation of invasive EEG recordings in the clinical setting, it has been perceived that a considerable proportion of epileptic discharges present at a cortical level are missed by routine scalp EEG recordings. Several in vitro, in vivo, and simulation studies have been performed in the past decades aiming to clarify the interrelations of cortical sources with their scalp an...

Myoclonic epilepsies are frequently related to mitochondrial disorders, lysosomal disorders and proteinopathic neurodegenerative diseases. Familial cortical myoclonic tremor with epilepsy (FCMTE) is a genetic form of myoclonic epilepsy. FCMTE is defined by an autosomal dominant inheritance, adult onset cortical myoclonic tremor and inconstant seizures. Electrophysiologic examinations show corti...

Benign childhood epilepsy with centrotemporal spikes (BECTS) is associated with cognitive and language problems. According to recent studies, disruptions in brain structure and function in children with BECTS are beyond a Rolandic focus, suggesting atypical cortical development. However, previous studies utilizing surface-based metrics (e.g., cortical gyrification) and their structural covarian...

The objective of this article is to review the pathophysiological bases of gray matter heterotopia and to appreciate their involvement in brain cortical development and functional consequences, namely epilepsy. The development of the cerebral cortex results from complex sequential processes including cell proliferation, cell migration, cortical organization, and formation of neuronal networks. ...

A big advance in epileptology has been the recognition of syndromes with distinct aetiology, clinical and EEG features, treatment and prognosis. A prime and common example of this is rolandic epilepsy that is well known by the general paediatricians for over 50 years, thus allowing a precise diagnosis that predicts an excellent prognosis. However, rolandic is not the only benign childhood epile...

Serotonergic abnormalities have been reported in both autism and epilepsy. This association may provide insights into underlying mechanisms of these disorders because serotonin plays an important neurotrophic role during brain development--and there is evidence for abnormal cortical development in both autism and some forms of epilepsy. This review explores the hypothesis that an early disturba...

The importance of the hippocampus, in epileptic networks, which underpin temporal lobe epilepsy, have long been appreciated. Advances in MR imaging has facilitated the identification of structural lesions in the hippocampus. In the past few years, hippocampal malrotation or incomplete inversion of the hippocampus is increasingly reported in patients with and without epilepsy and the clinical si...

We investigated sleep-related declarative memory consolidation in four children with focal idiopathic epilepsy. In a population of healthy control children, recall of learned pairs of words was increased after a night of sleep, but not after a daytime wakefulness period. In children with epilepsy (1 case of benign epilepsy with centro-temporal spikes, 1 case of benign childhood epilepsy with oc...
