what disease causes people to faint
Neurally mediated syncope (NMS) is called also neurocardiogenic, vasovagal, vasodepressor or reflex mediated syncope. 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.
