Active clinical trials for "Epilepsy"

The main objective of MAPCOG_SEEG is to create a database including brain recordings of cognition performed in clinical routine in patients during the pre-surgical SEEG assessment. This aims to be able to propose the first atlas of human cognition with a high temporal and spatial resolution.

The investigators are collecting genetic information through blood samples as well as clinical and EEG data from over 1000 people with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe and North America. This study will draw on both existing and new samples from JME patients. These will be compared to anonymised data from samples for 2000 controls. The goal of this study is to find the genetic cause of JME. Finding the cause will help create better treatments for JME, as well as improve patient outcomes by allowing us to detect it earlier.

The aim of this study is to register the drug treatment of depression in patients with epilepsy in East China.

In this prospective cohort study smartphone behavior surrounding epileptic seizures will be quantified, using a smartphone app, in order to optimize epilepsy evaluation and treatment

Background: - Drug resistant epilepsy is the term used to describe epilepsy that cannot be controlled by medication. Many people whose seizures do not respond to medication will respond to surgical treatment, relieving seizures completely or almost completely in one-half to two-thirds of patients who qualify for surgery. The tests and surgery performed as part of this treatment are not experimental, but researchers are interested in using the data collected as part of routine standard epilepsy care to better understand epilepsy and its treatment. Objectives: - To use surgery as a treatment for drug resistant epilepsy in children and adults. Eligibility: - Children and adults at least 8 years of age who have simple or complex partial seizures (seizures that come from one area of the brain) that have not responded to medication, and who are willing to have brain surgery to treat their medically intractable epilepsy. Design: Participants will be screened with a medical history, physical examination, and neurological examination. Imaging studies, including magnetic resonance imaging and computer-assisted tomography (CT), may also be conducted as part of the screening. Participants who do not need surgery or whose epilepsy cannot be treated surgically will follow up with a primary care physician or neurologist and will not need to return to the National Institutes of Health for this study. Prior to the surgery, participants will have the following procedures to provide information on the correct surgical approach. Video electroencephalography monitoring to measure brain activity during normal activities within a 24-hour period. Three to four 15-minute breaks are allowed within this period. Electrodes placed directly in the brain or on the surface of the brain to measure brain activities and determine the part of the brain that is responsible for the seizures (seizure focus). Participants will have a surgical procedure at the site of their seizure focus. Brain lesions, abnormal blood vessels, tumors, infections, or other areas of brain abnormality will be either removed or treated in a way that will stop or help prevent the spread of seizures without affecting irreplaceable brain functions, such as the ability to speak, understand, move, feel, or see. Participants will return for outpatient visits and brain imaging studies 2 months, 1 year, and 2 years after surgery.

obtain motion sequences of at least 60 epileptic seizures

The goal of this observational study is to learn about epilepsy after a stroke (post-stroke epilepsy). The main questions it aims to answer are: What make some patients develop epilepsy after a stroke? Does sleep have an impact on the development of post-stroke epilepsy? Participants will undergo: Electroencephalography (EEG) Magnetic resonance imaging (MRI) Polysomnography (only patients) Blood tests will also be taken. The patient group will be compared to the healthy controls. Researchers will also look into medical records of stroke patients hospitalized at St. Olavs hospital and collect relevant information.

Cerebral cavernous malformation (CCM)-related epilepsy (CRE) impairs the quality of life in patients with CCM. Patients could not always achieve seizure freedom after surgical resection of the lesion, suggesting an inadequate treatment and evaluation of the epileptogenic zone or network. Iron deposition in cerebral cavernous malformations has been postulated to play an important role in triggering CRE. Quantitative susceptibility mapping (QSM), as an optimal in vivo imaging technique to quantify iron deposition, is employed to analyze the iron quantity in CCM patients with epilepsy and further combined with brain structural and connectome analysis, to describe the difference between CCMs with and without epilepsy. In vivo biomarkers predicting CRE risk in CCM natural history and CRE control outcome after CCM surgical resection will be further identified to improve management strategy.

Tryptase, TLR4, and anti-NR2A antibodies were measured in serum, cerebrospinal fluid, and subjects and other markers to assess their relevance to disease activity, aiming to find new therapeutic targets,Timely intervention to improve the prognosis of SLE and improve the quality of life of patients with SLE.

Dreaming is a sleep-associated cognitive process whose neural substrates and functions remain poorly understood. In healthy subjects, the frequency of dream recall is influenced by several factors such as age, gender, interest in dreams and sleep quality. The content of dreams mainly depends on waking life experiences, especially when they are recent and have a strong emotional content. The function of dreams remains debated but it is widely accepted that dreams play a role in emotional regulation. Modifications in dreams are observed in several neurological diseases and sleep disorders, due to the modifications of sleep related to these diseases, as well as to associated disturbances in cognitive functioning and to the impact on such diseases on waking life. Epilepsy is a neurological condition characterized by a predisposition to seizures resulting from excessive and synchronized abnormal brain activity; it is associated with numerous co-morbidities including sleep and cognitive disorders, which are present in nearly one in two patients. However, the influence of epilepsy on sleep-related cognitive processes is poorly understood. It is suspected that nocturnal epileptic activity disturbs sleep-related memory consolidation processes, but the consequences of epilepsy on dreams have been little investigated. The study of the determinants (epilepsy syndrome, location of the epileptic focus, presence of sleep-related seizures, certain anti-epileptic treatments, alteration of the quality of sleep) of dream characteristics in this context could lead to a better understanding of the dreams physiology, the interactions between epilepsy and sleep, as well as the cognitive and emotional functioning related to sleep in epilepsy. It could also determine whether dream characteristics can provide information on the epilepsy syndrome and on the presence of nocturnal seizures, and thus constitute a diagnostic tool. In this cross-sectional observational study, we aim to identify determinants of dream recall in relation to epilepsy by administering a simple and brief questionnaire on sleep and dreams, to all consecutive patients seen in epileptology consultation during 12 months. Our objectives are To determine whether the presence of sleep-related seizures influences the frequency of dream recall in patients with epilepsy To describe the characteristics of dreams in epilepsy, the influence of epilepsy on dreams and to characterize the determinants of dream recall frequency in patients with epilepsy We hypothesize that the presence of seizures during sleep will be associated with poorer sleep quality, increased frequency of dream recall, and that we will observe the inclusion of epilepsy symptoms in dream content, particularly in subjects who are aware of their nocturnal seizures and are awakened by them.
