The Capsular Warning Syndrome (CWS) is a form of transient ischemic attack (TIA) that may precede a capsular stroke.


Clinical features of the CWS:

(1) The patient experiences repeated episodes of ischemia involving the internal capsule resulting in transient focal neurologic deficits.

(2) The deficits may consist of:

(2a) motor dysfunction in the face, arm and/or leg

(2b) sensory deficits

(2c) dysarthria

(3) Cortical signs are absent.


Diffusion-weighted MRI may be able to identify the affected area and suggest the affected artery.
