What are the symptoms of stroke?
Emergency signs
These are the emergency signs. If any occur, dial 999:
•Sudden weakness or numbness in the face, arm or leg on one side of the body.
•Abrupt loss of vision, strength, coordination, sensation, speech or the ability to understand speech. These symptoms may become more marked over time.
•Sudden dimness of vision, especially in one eye.
•Sudden loss of balance, possibly accompanied by vomiting, nausea, fever, hiccups or trouble with swallowing.
•Sudden and severe headache with no other cause followed rapidly by loss of consciousness – an indication of a possible stroke due to bleeding.
If you or someone with you manifests any of the signs of stroke, do not delay.
Call 999.
If the symptoms pass quickly, this may indicate a transient ischemic attack (TIA), a brief blockage of blood flow to the brain that is often a forerunner of stroke. Do not ignore this warning sign.
 You must get to the hospital immediately. Some treatments must begin within the first few hours of symptoms; early treatment can often help prevent a fatal or disabling stroke from occurring.
