Quick Answer

Syncope and seizure are two different medical conditions that can sometimes occur simultaneously, according to the American Heart Association. Syncope, also known as fainting, is a temporary loss of muscle control and consciousness, while a seizure is an involuntary change in sensation, consciousness, muscle control and behavior, as stated by Medtronic. It can be difficult to distinguish syncope from a seizure because they share some symptoms, but their causes are not the same.

Syncope is usually caused by temporarily inadequate blood flow to the brain, explains the American Heart Association. This lack of blood flow can have many causes, including but not limited to low blood pressure, emotional stress, dehydration, and some heart and lung disorders. While the primary symptoms of syncope are a loss of muscle control and consciousness, its other symptoms, such as twitching and confusion, are similar to those of a seizure, according to Medtronic,

Seizures, on the other hand, are caused by abnormal electric discharges in the brain, according to Medtronic. Symptoms of a seizure can range from staring off into space and altered vision to loss of consciousness and full body convulsions. Occasionally, prolonged syncope can trigger a seizure, according to the American Heart Association.
