A 56 year old man presents to the GP with an 18 hour history of left sided facial weakness and incoherent speech.
On examination, he has slightly reduced motor power in the left upper and lower limbs, reduced left sided facial movements and evidence of dysarthria. His blood pressure is 118/76 mmHg, pulse is 85 beats per minute, respiratory rate is 18 breaths per minute and oxygen saturations are 96% on air.
Given the likely diagnosis, what is the next most appropriate step in management?
