Abstract

Purpose of Review

To discuss the mechanisms of iron regulation in the brain and the pathophysiological role of deregulation of iron homeostasis following a stroke, and to review existing evidence supporting the potential role of iron chelators in the treatment of ischemic and hemorrhagic stroke.

Recent Findings

In recent years, accumulating evidence has highlighted the role of neuroinflammation in neurological injury after ischemic and hemorrhagic stroke, and that free iron is central to this process. Via the Fenton reaction, free iron catalyzes the conversion of superoxide ion and hydrogen peroxide into hydroxyl radicals, which promote oxidative stress.

Summary

Advances in our understanding of changes in brain iron metabolism and its relationship to neuronal injury in stroke could provide new therapeutic strategies to improve the outcome of stroke patients. Pharmacological agents targeting brain iron regulation hold promise as potentially effective treatments in both ischemic and hemorrhagic stroke.
