Neurocardiogenic Vasovagal Syncope - Symptoms and Treatment

Vasovagal syncope is the most common cause of fainting . It can affect people of all ages, but is particularly common in young women.  It is also known as Neurocardiogenic Syncope or Vasodepressor Syncope. Syncope is the temporary loss of consciousness due to a sudden decline in blood flow to the brain.

Syncope can occur in otherwise healthy people. It most often occurs when the blood pressure is too low and the heart doesn't pump a normal supply of oxygen to the brain. Syncope can even be life-threatening if not treated appropriately. If syncope occurs with exercise, or if it is associated with palpitations or irregularities of the heart visit a doctor immediately.

Syncope is common and disabling, but its causes are difficult to diagnose. An important issue is distinguishing syncope from several other symptoms. Dizziness, presyncope, and vertigo do not result in a loss of consciousness. Vertigo is associated with a sense of motion. Distinguishing syncope from seizure can sometimes be difficult. However, a loss of consciousness that is precipitated by pain, exercise, urination, defecation, or stressful events is usually associated with syncope and not seizure. Also, disorientation after the event, slowness in returning to consciousness, and unconsciousness lasting more than five minutes suggest a seizure.
