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.
