When stopping the antiplatelet drugs stopped the 'TIAs'

摘要

A 70-year-old woman reported recurrent episodes of right- or left-sided sen-sorimotor disturbance, thought to be recurrent transient ischaemic attacks. The episodes continued despite treatment with antiplatelet agents. When MRI revealed microhaemorrhages and focal superficial cortical haemo-siderin deposition, antiplatelet agents were discontinued and her transient focal neurological episodes stopped. The imaging appearances suggested cerebral amyloid angiopathy (CAA) associated with superficial siderosis-although fulfilling criteria only for 'possible CAA'. The case highlights the diversity of transient focal neurological episodes and the difficulties in cur-. rent terminology and understanding of the clinical manifestations of CAA.
