Increased focal interictal discharges during specific cognitive tasks

We present a patient with pharmacoresistant right temporal lobe epilepsy who showed a significant increase in focal interictal spikes in response to specific visuospatial tasks, Temporal spiking was particularly increased during immediate recall of visuospatial material, but not during verbal memory tasks. This reflexive phenomenon, situated in between cognitive alterations as seen in most patients with epilepsy and frank seizures elicited by higher cerebral function as in reflex epilepsy, is discussed in relation to cognition and underlying neural substrates.
