Language Mapping in Temporal Lobe Epilepsy in Children: Special Considerations
2012
Epilepsy Research and Treatment
Temporal lobe epilepsy (TLE) in children is a slightly different entity than TLE in adults not only because of its semiology and pathology but also because of the different approach to surgical treatment ...
This paper will highlight the specific challenges and solutions in mapping language in a pediatric population with TLE. ...
In patients requiring surgery near languagerelated eloquent brain areas (mostly for tumors), a german group combined MEG and fMRI and showed a good congruence between the two modalities (96%); however ...
