Conditions

Drug Resistant Epilepsy, Electroencephalogram (EEG), Magnetic Resonance Imaging

Brief summary

Using multimodal imaging technology, this study aims to explore the characteristics of epileptogenic foci in patients with drug-resistant epilepsy and identify key network nodes (such as central nodes) to provide more assistance for the diagnosis of drug-resistant epilepsy.

Detailed description

This study is a prospective observational cohort study. It prospectively recruited 50 patients with drug-resistant epilepsy from the Epilepsy Center of the Department of Neurology at Xijing Hospital, all aged 18 years or older. It collected general information and clinical baseline data such as magnetic resonance imaging; gathered multimodal imaging data once; analyzed the characteristics of epileptogenic foci in patients with drug-resistant epilepsy; and performed statistical analysis.

Design outcomes

Primary

MeasureTime frameDescription
The characteristics of hybrid imaging in patients with different types of refractory epilepsy.baselineBased on PET-FMRI-EEG hybrid fusion technology, explore the brain network characteristics of epilepsy patients.PET detects areas of reduced glucose metabolism, using radioactive isotopes (such as 18F-labeled fluorodeoxyglucose) to reflect the glucose metabolism of brain tissue. Typically in epilepsy patients, areas of hypometabolism may indicate the presence of epileptic foci. By using fMRI or EEG data, the synchronization of activities between different brain regions is analyzed to understand the organization and functional connectivity patterns of the brain network.
The characteristics of PET, fMRI, and EEG indicators in patients with different types of intractable epilepsy.baselineUsing different data analysis methods to explore the characteristics of PET, fMRI, and EEG indicators in patients with various types of intractable epilepsy.The characteristics of the power spectrum of various EEG frequency bands (Delta, Theta, Alpha, Beta, Gamma waves) and brain functional connectivity.

Secondary
