Summary

Spreading depression (SD) is linked to brain conditions like cerebral ischemia. Suppressing SD may reduce brain lesion size and protect neurons after stroke.

Area of Science:

  • Neuroscience
  • Pathophysiology

Context:

  • Spreading depression (SD) is a wave of neural and glial depolarization that propagates across the cerebral cortex.
  • Growing evidence links SD to various neurological conditions, including cerebral ischemia, migraine, epilepsy, and traumatic brain injury.
  • SD also influences physiological processes like sleep and arousal.

Purpose:

  • To review the relationship between spreading depression and cerebral ischemia.
  • To discuss the discovery and history of SD research.
  • To explore SD in the intact brain and peri-infarct SD in focal cerebral infarction.

Summary:

  • The review covers the discovery and history of spreading depression (SD).
  • It examines the role of SD in the intact brain and specifically in the context of focal cerebral infarction.
  • Peri-infarct SD is identified as a contributor to the expansion of ischemic lesions.

Impact:

  • Peri-infarct spreading depression (SD) exacerbates focal ischemic lesion growth.
  • Inhibiting SD presents a potential therapeutic strategy for reducing infarct volume.
  • Suppression of SD may offer neuroprotection for ischemic neurons following focal cerebral ischemia.
