Abstract
Intracranial
haemorrhages, including intracerebral haemorrhage (ICH),
intraventricular haemorrhage (IVH) and subarachnoid haemorrhage (SAH),
are leading causes of morbidity and mortality worldwide. In addition,
haemorrhage contributes to tissue damage in traumatic brain injury
(TBI). To date, efforts to treat the long-term consequences of cerebral
haemorrhage have been unsatisfactory. Incident rates and mortality have
not showed significant improvement in recent years. In terms of
secondary damage following haemorrhage, it is becoming increasingly
apparent that blood components are of integral importance, with
haemoglobin-derived iron playing a major role. However, the damage
caused by iron is complex and varied, and therefore, increased
investigation into the mechanisms by which iron causes brain injury is
required. As ICH, IVH, SAH and TBI are related, this review will discuss
the role of iron in each, so that similarities in injury pathologies
can be more easily identified. It summarises important components of
normal brain iron homeostasis and analyses the existing evidence on
iron-related brain injury mechanisms. It further discusses treatment
options of particular promise.
