Focal cerebral arteriopathy and childhood stroke.

ABSTRACT

PURPOSE OF REVIEW Focal cerebral arteriopathy (FCA) is one of the most common causes of arterial ischaemic stroke in a previously healthy child. Distinguishing between different subtypes of arteriopathy is challenging and has significant management implications. RECENT FINDINGS: Recent studies have helped to define the subtypes of focal cerebral arteriopathies and improved understanding of their clinical and radiological features. In addition, they have reported new evidence for the association between viral infection and inflammation in the pathogenesis of FCA and proposed new radiological, serum and cerebrospinal fluid biomarkers to guide diagnosis and management. There is limited evidence to guide treatment of FCA but a role for steroids and antiviral therapies have been reported. SUMMARY: Despite the recent advances there is a limited knowledge of the pathophysiology and outcomes following FCA. Research priorities include the identification of biomarkers to improve accuracy of initial diagnosis and predict progression, and interventional trials to determine best treatments to reduce stroke recurrence risk.
