The symptoms depend on the blood vessel being blocked and can be difficult to recognize because they can be very variable. For example, symptoms can include weakness, numbness, confusion, difficulty speaking, changes in vision, dizziness, etc.
Symptoms. Symptoms such as weakness of extremities, facial droop, speech problems, altered mental status---- all these are transient.
