Epileptic seizures and pseudoseizures in temporal lobe epilepsies were studied from the viewpoint of the hierarchy of consciousness. Twenty-two patients with temporal lobe epilepsies (TLE) who showed true amnesia or impairment of consciousness developing from the dreamy state, even though their actions and movement continued, were selected among 160 patients with TLE, nine patients with manifested pseudoseizures, pseudoseizure status, and complex partial seizure status (CPSE) were investigated. Twelve patients in whom impairment of consciousness followed the dreamy state recognized their own existence and maintained some self-directed consciousness. The other 10 patients with amnesia were aware of their goals. Furthermore, pseudostatus ranged from epileptic seizures during pseudoseizure status to pseudoseizures during status epilepticus (SE). In some cases of CPS, awareness and self-directed consciousness were only partially pseudoseizures, disorders of self-directed consciousness are assumed to influence awareness and arousal.

Voltage-gated potassium conductances [Formula: see text] play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing [Formula: see text] in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers.

A middle childhood boy with epilepsy exhibited persistent low concentrations of valproic acid, lamotrigine and topiramate for over 1 month, primarily due to pharmacokinetic interactions involving fosphenytoin, meropenem and phenobarbital. Awareness of these clinically significant interactions is crucial for ensuring effective seizure control. However, further research is needed to establish optimal evidence-based treatment strategies in complex paediatric cases.

Background: Cerebral hyperperfusion syndrome (CHS) is a rare but serious complication after carotid artery revascularization. This study aims to determine the impact of carotid artery stenting (CAS) modality on the incidence, severity and overall outcomes of CHS after carotid revascularization.
Methods: Data from patients who underwent CAS with either distal embolic protection (CAS+DEP) or transcarotid artery revascularization (TCAR) were obtained from the Vascular Quality Initiative (VQI) database 2016-2023.

Objectives: To evaluate the availability and consistency of commercial driving eligibility criteria for patients with seizures.
Methods: We systematically evaluated commercial driver's license regulations for patients with epilepsy, first acute symptomatic seizure and first unprovoked seizure in different countries. Government driving authority websites and published guidelines were accessed and if not available, local neurologists were contacted.

Background: Direct cortical electrical stimulation remains the gold standard for delineation of the primary motor cortex in patients with drug-resistant epilepsy (DRE) undergoing epilepsy surgery evaluation OBJECTIVE: This study aimed to explore the efficacy and safety of functional motor mapping through Stereo-EEG (SEEG) electrode contacts in children with DRE at our institute.
Methods: We performed a retrospective analysis of children who underwent SEEG evaluation and functional cortical mapping via bipolar electrical stimulation at our institution between July 2020 and June 2024. Detailed clinical, radiological and neurophysiological variable were extracted; qualitative and quantitative variables were summarized using appropriate descriptive statistics.
