Facial twitch during eeg

His neurological examination was normal; EEG showed right inferior frontal epileptiform discharges. EEG-fMRI showed increased blood oxygenation level-dependent contrast in the right inferior and middle frontal gyri corresponding to the contralateral motor and premotor cortex responsible for facial movements BA 44, 45, 45, 9 with widespread BOLD signal deactivations suggestive of epileptic network involvement despite a very focal epileptogenic process. We hypothesize that the response of some cases of HFS to carbamazepine, a first-line treatment in the pre-botulinum toxin era, may have been due to its anti-epileptic effects rather than to modulation of facial nerve hyperexcitability. In adults, the most common identifiable cause of EPC is cerebrovascular disease. Isolated hemifacial spasms are characterized by involuntary, irregular, clonic, or tonic movements of muscles innervated by the facial nerve. HFS is believed to result from hyperexcitability of the facial nerve nucleus or ephaptic transmission within the proximal facial nerve segment of the facial nerve nucleus.

EPILEPTIC SPASMS

More On: Brain Center , D. Jurriaan M. Unfortunately, an incorrect diagnosis of epilepsy not only exposes a child to the side effects of antiepileptic drugs but also eliminates an opportunity to treat his or her true condition. The problem is more common than you might think. Research from the U.
