Does Topiramate Adjust the Excitability of the Brain in Migraine Sufferers?
Status unconfirmed
Conditions studied: Migraine, Chronic Headache
In brief
The purpose of the study is to determine by the use of non-invasive magnetic stimulation if the medication Topiramate adjusts the excitability of the migraine sufferer's brain. Previous studies have shown the migraine sufferer's brain is more excitable. The magnetic stimulation device has given us a way to look at excitability and to see if it changes at the same time that a headache diary shows if the pattern or severity of headaches changes with the administration of the drug Topiramate. It is expected that as migraine sufferers have fewer headaches with topiramate the testing with magnetic stimulation will show that their brains are less excitable and that if the topiramate does not change the character of headaches then the pattern of excitabilty would not change from the baseline test before medication is started.
