Abstract

OBJECTIVE: Studies of focal epilepsy have revealed abnormalities of language organization; however, little attention has been paid to disorders of reading in this group. We hypothesized that language functional magnetic resonance imaging (fMRI) would reveal differences in language organization between focal epilepsy patients with and without reading difficulties. METHODS: We conducted language fMRI studies of 10 focal epilepsy patients with reading difficulties, 34 focal epilepsy patients without reading difficulties, and 42 healthy controls. RESULTS: We defined regions of interests on the basis of activation patterns on an orthographic lexical retrieval task. Comparison of activations withi..
