In this review, we provide information gathered from key findings dealing with the mechanisms of beta deposition in cerebral arteries, the diagnosis of different CAA types, and advances in treatment for CAA. Since CAA is a risk factor for ICH, we also review previously used in vivo and in vitro models of CAA and their features with respect to CAA-related ICH.

Patients who developed DCI had lower median 14,15-EET/20-HETE ratios compared to those without DCI.
