Pharmacological Modulation of Brain Oscillations in Memory Processing
EpilepsySeizures4 moreThe goal of this study is to learn about the effects of scopolamine (an anticholinergic drug) on areas of the brain involved in memory, and changes it may have on brain activity. The investigators will do this by testing epileptic patients who are already undergoing intracranial surgery for seizure monitoring, and measuring the activity from the brain areas being assessed. The main questions it aims to answer are 1) whether scopolamine changes memory activity solely at encoding (the time when the person perceives and determines to remember an item or event) as has previously been found, or if it also can selectively impact retrieval (when the item or event which has been processed is recalled or remembered), and 2) what the nature of the brain activity changes is. Participants will complete two treatment arms. One of these will be with the drug, and the other will be with a saline solution, so that the participants are unaware which session the actual drug has been received. Patients will complete a verbal and/or spatial task each of the two days. An anesthesiologist will administer either the drug or the saline at a critical point which addresses both of the research questions. Researchers will compare the brain activity between the two treatment arms to determine what brain activity changes, and at what time point during memory formation.

Tuberous Sclerosis ComplexThe purpose of this study is to evaluate the long-term safety in patients with TSC and refractory seizures who are currently receiving everolimus treatment in the Novartis-sponsored EXIST-3 study and who are determined to be benefiting from continued treatment as judged by the investigator at the completion of EXIST-3
Safety, Tolerability, and Exploratory Efficacy of Adjunctive EQU-001 for Seizures in Adults With...
EpilepsyThis is a double-blind, placebo controlled, randomized study of dose-ranging safety, tolerability, exploratory efficacy of adjunctive EQU-001 for seizures using the continuous reassessment method in patients diagnosed with epilepsy.
The Safety of Intravenous Tranexamic Acid in Patients Undergoing Supratentorial Meningiomas Resection...
SeizuresMeningiomaGrowing evidence of Tranexamic Acid (TXA) being used to reduce blood loss and blood transfusions in various guidelines. However, the adverse effects of TXA especially seizure has always been a problem of concern, especially in neurosurgery. Therefore, this study aims to provide a scientific evidence for the safety of TXA in supratentorial meningiomas resection patients.
Randomized, Double-blind Study to Evaluate Efficacy and Safety of Cenobamate Adjunctive Therapy...
Partial SeizureFocal SeizureThis is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, adjunctive therapy study in subjects with POS, with optional OLE. The study consists of 4 periods as follows: An 8-week of Screening/Baseline Period, 24-week of Double-blind Treatment Period (including a 18-week Titration Phase and 6-week Maintenance Phase), 52-week of Open-label Extension (OLE) Period (applicable for subjects who participate in the OLE) and up to 5-week of End of Study (EOS) Follow-up Period. The purpose of this study is to evaluate the efficacy and safety of 100, 200 and 400 mg/day of cenobamate as adjunctive therapy compared with placebo in subjects with partial onset seizures (POS). The study will also evaluate the long-term safety and tolerability of cenobamate adjunctive therapy in subjects with POS who have completed the double-blind treatment period.

Neuroimaging Biomarker for Seizures
Seizure DisorderSeizure Disorder7 moreThis multi-site study will examine patients with epilepsy (ES) following head injury [i.e., posttraumatic epilepsy (PTE)] and posttraumatic psychogenic Non-epileptic seizures (PNES) and will compare them to patients with traumatic brain injury (TBI) who do not have seizures using functional neuroimaging.
Retraining and Control Therapy (ReACT): Sense of Control and Symptom Expectations as Targets of...
ConvulsionNon-EpilepticThe purpose of this study is to assess sense of control and catastrophic symptom expectations as targets for Retraining and Control Therapy (ReACT- an intervention focused on changing behaviors and thoughts) for treatment of pediatric psychogenic non-epileptic seizures (PNES, episodes resembling epileptic seizures but with no medical explanation). 11-18-year-olds diagnosed with PNES will engage in twelve sessions of ReACT. Sense of control over actions will be measured by the magic and turbulence task, a well-validated measure of sense of control. Participants will complete the cold pressor test (CPT) in which participants hold their hand in cool water for as long as possible up to 3 minutes. Catastrophic symptom expectations in response to the CPT will be measured by Pain Catastrophizing Scale for Children (PCS-C) pain tolerance (time with hand in water) and cortisol response. Target assessments will occur 7 days before treatment, 7 days after 8th treatment session, 7 days after 12th treatment session, 6 months and 12 months after the 12th treatment session. PNES frequency will be measured from 30 days before to 12 months after treatment.
