What Are Some Symptoms of Neurocardiogenic Syncope?

Some symptoms of neurocadiogenic syncope include yawning, blurred vision, lightheadedness and dilated pupils. Neurocardiogenic or vasovagal syncope is a disorder in which the heart rate suddenly drops and blood pressure is lowered, notes Mayo Clinic. Vasovagal syncope is among the leading causes of fainting.

When blood pressure drops, the brain is deprived of adequate blood, leading to a temporary fainting episode. Anyone can suffer from a neurocardiogenic syncope. However, young children and the elderly are at a greater risk of experiencing the condition, according to Healthgrades. This condition in itself is no cause of alarm but may sometimes lead to serious injuries due to falls.

Just before a neurocardiogenic syncope attack, individuals are likely to experience a blurring of vision. They are also likely to lose sight of objects or people that are not close. Certain individuals may develop pale skin and a cold, clammy sweat. A feeling of warmth is also quite common. During the incident, individuals are likely to have dilated pupils. They may make jerky, abnormal movements and have a slow, weak pulse.

Neurocardiogenic syncope is diagnosed by taking a patient's medical history and performing a physical examination. In most cases, doctors do not have to treat this condition because it is only temporary. Physical therapies to prevent pooling of blood in the legs and certain medications for treating low blood pressure may be used in management of the condition.
