The first symptom of intracranial stenosis is most often a transient ischemic attack (TIA) or ischemic stroke. A TIA, often referred to as a warning stroke, has symptoms similar to an ischemic stroke, but which last just 2 to 30 minutes.
Symptoms occur suddenly, and time is vital. If you notice one or more of these signs in another person or in yourself, do not wait to seek help. Call 9-1-1 immediately.
The signs of a stroke are:

- Sudden trouble walking
- Dizziness, loss of balance or coordination
- Sudden, severe headache with no known cause
