clinical features
Last reviewed 01/2018
The clinical features of a transient ischaemic attack are highly dependent upon the arterial territory affected:
Carotid artery TIA - 90%:
Vertebro-basilar artery TIA's - 7% - are more diverse:
TIA's of uncertain vascular territory - 3% - have patterns which are difficult to fit into either anterior or posterior circulation TIA's e.g. dysarthria with hemiparesis.
