Abstract/OtherAbstract:
Spreading depression (SD) is an intense depolarization wave implicated in brain injury. In focal ischemia, recurrent peri-infarct depolarization (PID) waves akin to SD worsen the ischemic injury by exacerbating the blood flow-metabolism mismatch. We recently showed that gabapentin suppresses SD. We, therefore, tested gabapentin on PIDs and stroke outcome. Gabapentin pretreatment (200  mg/kg, intravenously) reduced the infarct volume by 23% after transient focal ischemia in mice. However, the frequency and duration of PIDs were not suppressed when recorded for 2  hours during ischemia, suggesting that gabapentin reduces infarct volume independent of PID suppression.
