Abstract :

Epilepsy is a network disorder with properties that inherently generate neuroplasticity. Accordingly, even focal, lesional forms
of the disorder initiate neuroplastic responses throughout large regions of cortex, disrupting a wide array of neurocognitive
networks. I The author will focus on temporal lobe epilepsy, describing the cognitive reorganization emergent during the
disease course, providing evidence from task-based Functional Magnetic Resonance Imaging (fMRI), resting-state functional
connectivity, and diffusion tensor imaging for both intra- and inter-hemispheric shifts in cognitive representations. Factors that
mediate changes in seizure and cognitive network organization are described, with a discussion of the neuroplastic responses
that can emerge following a common treatment for the disease, i.e., anterior temporal lobectomy. I The author will argue that
only by understanding and measuring the potential for neuroplasticity will we be able to effectively predict cognitive outcomes
in epilepsy, as it is these neuroplastic responses that govern the status of both neurocognitive and epileptogenic networks postsurgery.
Multi-modal imaging is discussed as a means of estimating neuroplastic potential, delineating the potential cognitive
mechanisms that might be available to serve recovery and good better cognitive outcomes.
