- It's a benign (and the most frequent) cause of fainting. However, life-threatening conditions may also manifest as syncope. NMS is more common in children and young adults, although it can occur at any age. NMS happens because blood pressure drops, reducing circulation to the brain and causing loss of consciousness. If the syncope is prolonged, it can trigger a seizure.

Determining the cause of fainting spells Older adults are at particular risk of syncope, which causes up to 30% of falls. Dehydration, gait disorders, and autonomic dysfunction are contributing factors. Orthostatic hypotension is a common precipitant that may be confused with seizure or transient ischemic attack (as when the episode occurs following a meal).

How is fainting (syncope) diagnosed? Heart valve conditions. Abnormalities with the heart valves can also cause fainting or syncope.

Passing Out - Fainting Overview, Causes, & Risk Factors. Fainting is a temporary loss of consciousness and muscle tone. It is caused by not having enough blood flow to the brain. When there is not enough blood flow to the brain, passing out protects the brain from damage. People who faint generally lose muscle tone and fall to the ground. When someone is lying on the ground, the blood being pumped out of the heart doesn't have to fight gravity to get to the brain.
