Reducing Seizure Frequency Using Cooling of the Head and Neck

2014-08-27 03:54:59 | BioPortfolio

Summary

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.

Description

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.

Medical and Biotech [MESH] Definitions

Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.

Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements. (From Rev Neurol 1998 Feb;26(150):256-261; Sports Med 1998 Feb;25(2):131-6)

Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)

Layer between the superficial fat compartment and superficial facial muscles in the head and the neck.

A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
