What causes neurologic syncope?
Neurocardiogenic syncope is caused by an abnormal or exaggerated autonomic response to various stimuli, of which the most common are standing and emotion. The mechanism is poorly understood but involves reflex mediated changes in heart rate or vascular tone, caused by activation of cardiac C fibres.
Does syncope affect the brain?
Syncopal episodes are typically triggered by a sudden, temporary drop in blood flow to the brain, which leads to loss of consciousness and muscle control. The person then falls down or over, which allows blood flow to return to the brain.
How serious is neurocardiogenic syncope?
Neurocardiogenic syncope is common and usually doesn’t indicate a more serious underlying health condition. When a person faints, and lies or falls down, normal blood flow to the brain resumes and consciousness returns.
Can you grow out of neurocardiogenic syncope?
Outlook. Most patients with neurally mediated syncope will outgrow their symptoms. This may take several years though. Patients who are fainting despite these measures can be seen in our Syncope Clinic.
What is the difference between pots and neurocardiogenic syncope?
“There seems to be some confusion distinguishing between these two groups because in some fainters, the heart rate increases to levels that may suggest POTS, but POTS patients do not exhibit hypotension,” they said in a joint email. “Also, POTS is chronic with day-to-day symptoms, while syncope is episodic.”
How can neurocardiogenic syncope be prevented?
These might include:
- Avoiding triggers, such as standing for a long time or the sight of blood.
- Moderate exercise training.
- Discontinuing medicines that lower blood pressure, like diuretics.
- Eating a higher salt diet, to help keep up blood volume.
- Drinking plenty of fluids, to maintain blood volume.
Is neurocardiogenic syncope a disability?
If you suffer from neurocardiogenic syncope (NCS), or vasovagal syncope, a central nervous system disorder, you may have repeated bouts of fainting. This type of syncope can make you eligible for disability benefits.
Is neurocardiogenic syncope genetic?
There are no published molecular genetic studies in vasovagal syncope.
