When sudden unsteadiness or severe dizziness occurs, how can delays in cerebrovascular assessment be avoided?

First ensure safety, avoid walking alone or driving, and note the time when symptoms suddenly appeared. If accompanied by speech abnormality, facial drooping, limb weakness or numbness, visual disturbance, severe headache, or altered consciousness, call emergency services immediately; even if symptoms later improve, do not rule out a cerebrovascular problem on your own.
