symptom can be enough to justify emergency evaluation.**
The Bottom Line
A stroke usually does not give a predictable warning days in advance. The most important warning signs tend to appear suddenly.
Facial drooping, arm weakness, speech difficulty, vision changes, severe imbalance, sudden confusion, and an unexplained severe headache should never be ignored.
And if symptoms disappear, that does not mean the danger has passed. It could be a TIA.
Recognizing the signs and acting immediately can help someone receive treatment sooner and may reduce the risk of permanent disability
