The National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health, is looking for individuals to participate in clinical studies. Participating in clinical trials allows you to play an active role in research on the nature and causes of many disorders of the brain and nervous system, and to possibly help physician-scientists develop future treatments. The information below is designed to help you quickly learn about actively recruiting research studies for which you or someone you know may be eligible.


This is a pilot, prospective, single center, randomized, placebo-controlled, double-blind trial, that assesses the number of NES in patients treated with flexible dose sertraline (Zoloft). This study will provide outcomes data and the effect size necessary for a future R01, multi-center randomized control trial. Secondary objective variables include reduction in depression, anxiety, impulsivity scores, and improvement in psychosocial functioning. After being diagnosed with NES by video electroencephalogram monitoring (vEEG), up to 50 participants will be enrolled and monitored during a two week lead in period for their baseline NES and psychosocial symptoms and functioning. At week 2, they will be blindly randomized to the treatment arm with flexible dose sertraline (25 to 200mg) or to the placebo control arm. The dose will be titrated over 4 weeks up to 200mg or to dose limited by side effects. The subjects will stay on their maximum fixed dose for the next 4 weeks. At week 10, the subjects may elect to remain on the sertraline or they can taper off the medication over the final two weeks of the treatment trial. After the treatment trial, the subjects will have follow up phone calls at month 4, 8, and 12 after enrollment to assess seizure status, medication usage, and global functioning. Upon enrollment, subjects will be evaluated with a structured psychiatric and neurological exam, and with bi-weekly, 30 to 60 minute appointments where they will complete symptom and function scales. They will keep a seizure diary prospectively, to evaluate their daily seizure activity. They will be given two weeks of the medication at each visit. In the first phase of the study 12 patients were screened and 8 enrolled in an open label trial of flexible dose sertraline. In the second phase of the study, 38 patients enrolled in the pilot, randomized, placebo-controlled trial.
