Predictive Value of Biomarkers of the Alzheimer's Disease (AD) in Elderly Patients With New-onset...
EpilepsyBeyond 60 years, the prevalence of epilepsy is estimated at approximately 1% and increases with age. In these patients, the etiology of epilepsy is unknown in 25% of cases, even up to 55% after 65 years. Although new-onset epilepsy in the elderly is associated with a vascular disease in 50% of cases, the hypothesis of an ongoing neurodegenerative process, including an Alzheimer's disease (AD), is also common. However, investigators do not have any marker that might help to identify the patients who develop epilepsy after 60 years and who might be, despite a normal cognitive functioning, already engaged in the pathophysiological process of AD. A number of data suggest a link between the pathophysiological process of AD and epileptogenesis: (i) a third of patients with epilepsy develops MA, (ii) the occurrence of epilepsy in AD is an aggravating factor for cognition, (iii) in animal models of AD, the relationship between neuronal hyperexcitability and amyloid deposits is bidirectional, the amyloid protein has a pro-seizure effect and the presence of epilepsy increases the amyloid deposits, (iv) in these models, the administration of an antiepileptic drug protects from deterioration of cognition, (v) the close relationship between amyloid and neuronal hyperexcitability might be mediated by the inflammatory processes associated with AD, and particularly the microglial activation which role in epileptogenesis has been shown elsewhere. Investigators hypothesize that in a subgroup of patients who develop epilepsy after 60 years, the occurrence of epilepsy might reflect the presence of an ongoing amyloid pathology. Our goal is to identify through biomarkers of AD in the cerebrospinal fluid of patients who develop an epilepsy after 60 years with normal MRI and normal cognition those at high risk of later developing clinically defined AD. Identifying patients with amyloid pathology which would be expressed through epilepsy before the onset of cognitive dysfunction might help to adapt both the management of seizures and of the cognitive dysfunction.

Efficacy of TDCS for Treating Working Memory Dysfunction and Depression in Temporal Lobe Epilepsy...
EpilepsyMemory difficulty ranks among the most common complaints for patients with temporal lobe epilepsy. While these cognitive problems may affect quality of life more than seizure frequency, no effective therapy exists. Transcranial Direct Current Stimulation (tDCS) is a method of safe, noninvasive, and painless brain stimulation delivering low intensity direct current through scalp electrodes to modulate brain activity. Several recently published studies demonstrate the enhancement of working memory and mood with stimulation of the frontal region of the brain. Furthermore, tDCS has never been reported to have induced a seizure. The aim of our study is to determine whether real tDCS can improve memory function and mood. The investigators are enrolling patients with well-controlled temporal lobe epilepsy who have not undergone brain surgery.
The Effect of Ketogenic Dietary Therapy on Sleep in Adult Epilepsy
EpilepsySeizuresThe modified Atkins diet, a form of ketogenic therapy in which individuals severely restrict their carbohydrate intake and subsequently enter ketosis, has begun to be used as an adjunctive treatment in adults with intractable epilepsy who are not surgical candidates. In this study, the investigators examine the effect of ketogenic dietary therapy on sleep, as sleep deprivation is one of the most common seizure triggers and seizures themselves have been found to affect sleep quality. This pilot study will enroll twenty participants, ten of whom are initiating ketogenic dietary therapy and ten participants who are being treated with standard anti-seizure drug therapy.
Anxiety and Depression in Epilepsy: A Pilot Treatment Study
AnxietyDepression1 moreAs a potential solution to address high rates of depression and anxiety seen in epilepsy patients and poor mental health care access, this trial aims to carry out treatment for depression and anxiety directly in the epilepsy clinic. Patients that meet eligibility criteria, including significant symptoms of depression and/or anxiety, will be enrolled in the intervention. The intervention will consist of an initial prescription for an FDA-approved medication to treat depression/anxiety and telephone-based chronic care management plan for repeated symptom measurement and side effect surveillance. The purpose of this pre-piloting limited study is to streamline recruitment, intervention and outcome assessment process in preparation for a randomized, controlled pilot of the intervention.
Imaging Neuroinflammation in Epilepsy With Ferumoxytol MRI
EpilepsyThe investigators plan to study inflammation in the brain (neuroinflammation) in human patients with epilepsy using a novel, non-invasive technique that has been proven successful in humans with other neuroinflammatory diseases. This technique uses ferumoxytol, a drug with minimal side effects that is FDA-approved for the treatment of iron deficiency anemia, as the contrast agent in magnetic resonance imaging (MRI). The study will recruit epilepsy patients who are admitted to Dartmouth-Hitchcock Medical Center (DHMC) for video-electroencephalography (video-EEG) monitoring in order to evaluate their candidacy for curative brain surgery. During the hospital stay and after informed consent, the patient will receive a standard-dose intravenous injection of ferumoxytol, and undergo one session of MRI at 24-48 hours after the injection. The patient will also undergo a separate "baseline" MRI session (if not already done at DHMC) at admission or at more than four weeks after the injection but before any brain surgery. Brain regions that preferentially uptake ferumoxytol are localized by subtracting the post-injection MRI session from the "baseline" MRI session. The investigators will investigate whether these regions overlap with the epileptogenic focus, namely the region that generates epilepsy and is localized by video-EEG and other diagnostic measures. Lastly, for those patient participants who thereafter undergo brain surgery, DHMC neuropathologists will use special stains to detect and quantify neuroinflammation in brain tissue removed, and the results will serve as the reference for the investigators to measure the sensitivity and specificity of ferumoxytol-based MRI in detecting neuroinflammation.

Impact of Interictal Electroencephalographic Abnormalities on the Stability of Attention in the...
EpilepsyCognitive disorders are a major problem in patients with epilepsy. One hypothesis is that the anomalies EEGs (AIC) may be responsible for short periods of attentional fluctuations causing a reduction of intellectual efficiency of patients. In this project, we propose to evaluate the impact of AIC on cognitive performance, specifically on attentional performance (central parameter of cognitive functioning) through the use of a computerized cognitive test (called STABILO, detailed below after) to measure, with good temporal sampling, the level of attentional engagement of patients in relation to their EEG activity. The originality of this study lies in the synchronization of two examinations usually made independently (EEG and psychometric testing), respecting a precise temporal coupling. The aim is to provide clinicians with a tool to assess very quickly attentional fluctuations in epileptic patients, and to assess the potential impact of AIC on the occurrence of these changes, with possible therapeutic implications (treatment of AIC and / or specific treatment of attention deficit disorder). The main objective of this study is to assess whether the presence of AIC EEG can induce a weakening of attentional performance.
Computerized Cognitive Training for Patients With Epilepsy
EpilepsyThis is a study on the effectiveness of computerized cognitive training for treatment of memory disorders in patients with epilepsy. Participants will be recruited from patients referred for neuropsychological assessment through the NYU Comprehensive Epilepsy Center's inpatient and outpatient services. Individuals meeting inclusion criteria will be screened for the presence of memory disturbance (defined by results of neuropsychological testing) and lack of exposure to any previous form of computerized cognitive training. All eligible subjects will be provided with an account for Lumosity with instructions to complete training modules 5 days per week for a total of 8 consecutive weeks. Outcomes will be evaluated through changes on the neuropsychological test battery.
