What are the other Names for this Condition? (Also known as/Synonyms)

• Nervous System-Mediated Syncope
• Reflex Syncope
• Vasovagal Syncope

What is Neurocardiogenic Syncope? (Definition/Background Information)

• Neurocardiogenic Syncope is a common form of fainting that occurs due to a temporary disruption in the autonomic nervous system. It involves a sudden drop in blood pressure and a slowing of the heart rate, leading to a brief loss of consciousness
• The condition is also known as Vasovagal Syncope and is a form of dysautonomia. This condition that occurs due to a sudden drop in heart rate and blood pressure is triggered by a reflex response, often resulting from emotional stress, pain, or standing for extended periods
• The signs and symptoms of Neurocardiogenic Syncope may include lightheadedness, nausea, sweating, and loss of consciousness. The diagnosis involves evaluating medical history, performing physical exams, and ruling out other causes
• The treatment of Neurocardiogenic Syncope may involve lifestyle modifications, increased fluid and salt intake, medications, and counter-pressure maneuvers. The prognosis is generally favorable, with most individuals experiencing infrequent and manageable episodes

Who gets Neurocardiogenic Syncope? (Age and Sex Distribution)

• Neurocardiogenic Syncope can affect individuals of all ages, including children and adults
• It is more common in younger individuals, with peak onset occurring between the ages of 10 and 30
• Both males and females can experience this disorder
• The condition may occur worldwide, affecting individuals of all racial and ethnic groups

What are the Risk Factors for Neurocardiogenic Syncope? (Predisposing Factors)

The risk factors of Neurocardiogenic Syncope may include:

• Family history: Having a family history of Neurocardiogenic Syncope increases the risk
• Age: Younger age groups are more prone to experiencing this form of fainting (syncope)
• Triggers: Certain triggers, such as standing for prolonged periods, emotional stress, heat, or pain, may predispose individuals to syncope episodes

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.

What are the Causes of Neurocardiogenic Syncope? (Etiology)

The exact cause of the development of Neurocardiogenic Syncope is not fully understood.

• However, it is believed to occur due to a reflex response involving the autonomic nervous system
• Triggers, such as emotional stress, pain, or specific situations, can lead to a sudden drop in blood pressure and heart rate, resulting in fainting

What are the Signs and Symptoms of Neurocardiogenic Syncope?

The signs and symptoms of Neurocardiogenic Syncope may be mild or severe and can vary from one individual to another. These may include:

• Feeling lightheaded or dizzy
• Blurred vision
• Pale skin
• Sweating
• Nausea
• Yawning
• Loss of consciousness (fainting), which is usually for brief periods

How is Neurocardiogenic Syncope Diagnosed?

A diagnosis of Neurocardiogenic Syncope may involve the following tests and exams:

• Medical history and symptom assessment: The physician may inquire about the individual's symptoms, triggers, and medical history
• Physical examination: Blood pressure and heart rate measurements in different positions (lying, sitting, and standing) are taken to observe the response to postural changes
• Tilt table test: This specialized test involves tilting the person at different angles while monitoring blood pressure and heart rate to provoke syncope and determine its cause
• Laboratory tests and radiological imaging studies, as needed

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

What are the possible Complications of Neurocardiogenic Syncope?

The complications of Neurocardiogenic Syncope may include:

• Falls and injuries: Loss of consciousness can result in falls and subsequent injuries
• Reduced quality of life: Frequent syncope episodes can lead to anxiety, fear of fainting, and limitations in daily activities

How is Neurocardiogenic Syncope Treated?

The treatment of Neurocardiogenic Syncope may involve the following measures:

• Lifestyle modifications: Strategies, such as avoiding triggers, maintaining hydration, and practicing counterpressure maneuvers, can help manage symptoms
• Medications: In some cases, medications may be prescribed to control blood pressure or regulate heart rate

How can Neurocardiogenic Syncope be Prevented?

Prevention strategies for Neurocardiogenic Syncope focus on identifying triggers and implementing appropriate lifestyle modifications. Understanding individual triggers and making necessary adjustments can help reduce the frequency of syncope episodes.

What is the Prognosis of Neurocardiogenic Syncope? (Outcomes/Resolutions)

The prognosis of Neurocardiogenic Syncope is generally good in most individuals.

• With lifestyle modifications and management strategies, most individuals can effectively control their symptoms and prevent recurrent syncope episodes
• However, the condition can be unpredictable, and individual responses to treatment may vary
