What are the symptoms of a transient ischemic attack?

The signs and symptoms of a TIA are like those of a stroke. They can include: sudden weakness on one side of the body (hemiparesis); inability to move or lift the arm; sudden paralysis of one side of the body (hemiplegia); movement and coordination problems; cognitive problems such as confusion, difficulty with speech, understanding speech, formulating thoughts and memory loss; blurred vision, loss of vision, or seeing only half the regular vision field (hemianopia), or sudden blindness in one eye. The difference between a TIA and a stroke is that a TIA usually passes within minutes, causing little lasting damage, while a stroke's effects are permanent. Thus, it is neither possible nor advisable to try to tell a TIA from a stroke while it is occurring.
