Focal cortical dysplasias (FCDs) are congenital malformations of cortical development that are a frequent cause of refractory epilepsy in both children and adults. With advances in structural and functional neuroimaging, these lesions are increasingly being identified as a cause of intractable epilepsy in patients undergoing surgical management for intractable epilepsy. Comprehensive histologic...

The aim was to examine the occurrence of benign partial epilepsy in infancy (BPEI). BPEI was defined as epilepsies with complex partial seizures (CPS) or secondary generalised seizures (SGS), or both, compatible with the following characteristics: normal development before and after onset, no underlying disorders, normal interictal electroencephalograms (EEGs), and good response to treatment. A...

Malformations of cortical development are associated with epilepsy and cognitive dysfunction, and can occur in patients with SCN1A ion channel mutations. We report a novel and subtle bandlike subcortical heterotopia on integrated positron emission tomography-magnetic resonance imaging ( PET-MRI) in a patient with treatment-resistant epilepsy due to a de novo KCNQ1 frameshift mutation. Our case ...

We present the case of a 13-year-old child with nocturnal frontal lobe epilepsy (NFLE) related to a right cingulate gyrus cortical dysplasia, who also presented with psychogenic nonepileptic seizures (PNES) and interictal antisocial behavior. The association of drug-resistant epilepsy with behavioral disorders is well established, but the role of epilepsy surgery in these patients is still cont...

Bathing-related epilepsy (BRE), which is also known as water immersion epilepsy, is a rare, benign, reflex epilepsy. It presents with focal seizures that occur during bathing with hot water and has a favorable prognosis (1). The exact mechanism underlying these seizures is unknown (1). This epilepsy is frequently confused with hot water epilepsy (HWE) and is generally seen during childhood and ...

Benign rolandic epilepsy (BRE) is a partial idiopathic epilepsy of childhood presenting with a nocturnal seizure and with a typical EEG showing centrotemporal spike and multifocal or generalized sharp slow waves. Although normal neurological and intellectual development are expected in BRE, it is not infrequent to detect subtle defects in neuropsychological functions and neuromotor development....

PURPOSE Focal cortical dysplasia (FCD) is the most common pathological diagnosis in patients who have undergone surgical treatment for intractable neocortical epilepsy. However, presurgical identification of MRI abnormalities in FCD patients remains difficult, and there are no highly sensitive imaging parameters available that can reliably differentiate among FCD subtypes. The purpose of our st...

OBJECTIVE To investigate the clinical and neurophysiological characteristics of epileptic negative myoclonus as the first and only ictal symptom of benign epilepsy with centrotemporal spikes. METHODS Electrophysiological evaluations included polygraphic recordings with simultaneous video electroencephalogram monitoring and tests performed with patient's upper limb outstretched in standing pos...

PURPOSE To identify the morphological vascular characteristics of cerebral arteriovenous malformations (AVMs) that predict a clinical presentation of epilepsy. METHOD Fifteen angioarchitectural characteristics of brain AVMs were selected for assessment in 100 consecutive patients referred to our institution for endovascular treatment. In this population, 47% of the AVMs were diagnosed as a co...

PURPOSE Although absence epilepsy is considered to be a prototypic type of generalized epilepsy, it is still under debate whether generalized 3 Hz spike-and-wave discharges (SWDs) might have a cortical focal origin. Here it is investigated whether focal interictal epileptiform discharges (IEDs), which typically occur in the electro- (EEG) and magnetoencephalogram (MEG) in case of focal epilepsy...
