Syncope is best described as

Syncope is a brief loss of consciousness caused by a temporary drop in blood flow to the brain, with a rapid return to baseline once perfusion is restored. This is why it’s described as fainting—the person appears to pass out but recovers quickly afterward. It’s not a prolonged cognitive change like delirium or confusion, which lasts longer and doesn’t involve a sudden, transient LOC. It isn’t a seizure with convulsions, which includes rhythmic jerking and a distinct postictal recovery that isn’t tied to cerebral hypoperfusion alone. Dizziness with blurred vision represents presyncope or vertigo symptoms without actual loss of consciousness.
