Clinical Trial: Reducing Seizure Frequency Using Cooling of the Head and Neck
This study is currently recruiting patients.
|
Purpose
Doctors use cooling of the brain to help stop seizures. This procedure is usually accomplished through surgery. Cooling of the face and scalp may also cool the brain, avoiding the need for surgery.
The purpose of this study is to assess a head-neck cooling device that the patient can wear. Researchers will determine whether the device can change the frequency of seizures in people with epilepsy.
Study participants must be 21 years of age or older and must experience seizures that occur once a week on a regular basis. Participants will be asked to keep a detailed seizure diary for a 12-week period before the date of the first cooling session. For each of the four cooling sessions, participants will be admitted to the hospital overnight. They will undergo a physical and neurological exam and an EEG (electroencephalogram). They will also swallow a temperature-sensor pill. Participants will have one 60-minute cooling session once a week for 4 weeks. Investigators will paste temperature-sensing electrodes on the scalp, forearm, abdomen, and leg. Participants will then be fitted with the cooling unit and the session will begin.

Official Title: Cooling of the Head and Neck to Reduce Seizure Frequency: A Pilot Study
Expected Total Enrollment: 5
Study start: August 11, 2003
Previous experimental as well as clinical reports have clearly shown that cooling of the brain does have inhibitory effects on epileptiform discharges and seizures. We hypothesize that mild cooling of the brain has anti-epileptic effects in epileptic patients who either have no identifiable seizure foci, who have multiple foci, or who have frequent localization-related seizures that are refractory to antiepileptic drugs. We have studied the feasibility and safety of a head-neck cooling device in 10 adult normal volunteers, and found that the head-neck cooling was feasible and safe, without significant complaints or problems voiced by the subjects. Overall, a slight reduction of core temperature was shown. Since cooling on a twice-a-week basis was well tolerated by normal volunteers, we would like to extend our study to patients with epilepsy to learn the optimal duration and frequency of head-neck cooling in terms of reducing seizure frequency. This will be a pilot study, as directed by PIRC and the IRB, in which we will evaluate 60 minutes of cooling performed once a week for 4 weeks in 5 epileptic patients. We will then report the results to PIRC and the IRB before we proceed with further study.
