Approximately 4.3 million (1.8%) adults and 750,000 (1.0%) children in the United States have been diagnosed with epilepsy or other seizure disorders; approximately one-third have seizures refractory to medical therapies.1,2 MRI is essential for the assessment of these patients with medically refractory epilepsy, as it … more »

A majority of the resting-state functional MRI literature on epilepsy describes connectivity differences in patients with epilepsy compared with healthy controls. Some studies reported diffuse decreased connectivity, while others found regions with increased connectivity, and still others found both. The diversity of these results … more »

Epilepsy is considered a disorder of large neural networks. There is considerable interest in examining the neural networks in patients with epilepsy. Functional connectivity and structural connectivity can be assessed using fMRI and diffusion tensor imaging, respectively. Resting-state networks refer to spatially segregated brain regions … more »
