fMRI of triggerable aurae in musicogenic epilepsy.
نویسندگان
چکیده
The authors studied a patient with musicogenic epilepsy triggered by one specific musical piece using 3D PRESTO fMRI. During epileptic aurae initiated by the stimulus, signal increases were found in the left anterior temporal lobe, correlating with ictal EEG and SPECT showing a left anterior temporal focus, and the right gyrus rectus. Because fMRI indicated a cascade of recruitment of the ventral frontal lobes by epileptogenic music, left anterior temporal lobe activity could be secondary to a right gyrus rectus focus, possibly triggered by emotional processing of music.

The origin of the focal spike in musicogenic epilepsy.
To clarify the pathogenesis of a typical case of musicogenic epilepsy, we examined interictal spikes using the dipole tracing method (DTM). The patient was a 49-year-old, right-handed Japanese man. He first experienced seizures at the age of 32 years; listening to his favorite piece of music frequently triggered them. His seizure type is partial (often complex, but sometimes simple). An interic...
متن کاملPresurgical Language Mapping in Patients With Intractable Epilepsy: A Review Study
Introduction: about 20% to 30% of patients with epilepsy are diagnosed with drug-resistant epilepsy and one third of these are candidates for epilepsy surgery. Surgical resection of the epileptogenic tissue is a well-established method for treating patients with intractable focal epilepsy. Determining language laterality and locality is an important part of a comprehensive epilepsy program befo...
متن کاملIctal SPECT in a case of pure musicogenic epilepsy.
A 39-year-old, right-handed woman had seizures for two years which were always triggered by exposure to various types of music: the first occurred while she listened to a tune she particularly liked, Con Te Partiro, by Andrea Boccelli. Other triggering factors were various types of music such as supermarket background music and polyphonic singing or instrumental music played by family members. ...
متن کاملThe running down phenomenon in temporal lobe epilepsy.
We compared 100 patients with temporal lobe epilepsy, who exhibited the running down phenomenon following temporal resections, with two groups of patients: 100 patients who became seizure-free, and 100 patients who continued to have frequent seizures following temporal resection. We found a significant correlation between prognosis and the size of the epileptogenic area as defined; patients wit...
متن کاملCombined MEG and fMRI model
An integrated model for magnetoencephalography (MEG) and functional Magnetic Resonance Imaging (fMRI) is proposed. In the proposed model, MEG and fMRI outputs are related to the corresponding aspects of neural activities in a voxel. Post synaptic potentials (PSPs) and action potentials (APs) are two main signals generated by neural activities. In the model, both of MEG and fMRI are related to t...
