This article was written by Dr. Aursulesei Ruxandra, pediatric neurologist specialist with extensive experience in diagnosing and treating neurological conditions. Pediatric neurology plays an important role in the periodic neurological evaluation of premature infants, as well as of all newborns at risk of developing neurological sequelae, with the goal of early detection and treatment of any impairment of the nervous system.
What is syncope?
Syncope represents a sudden loss of consciousness and postural tone, associated with a reduction in the energy supply at the brain level, usually caused by a decrease in either cerebral blood flow, oxygen saturation, or a combination of both causes.
Syncope is, in most cases, of 2 types:
- vasovagal
- cardiogenic
Vasovagal syncope will be presented below.

Is syncope epilepsy?
Although it is frequently confused with epilepsy, syncope is not epilepsy, nor does it foreshadow the onset of future epilepsy.
What is the difference between syncope and an epileptic seizure?
Criteria | Syncope | Epileptic seizure |
Position | Usually standing (vasodepressor) | Any position |
Precipitating factors | Crowded places, hunger, unpleasant circumstances | Rare |
Frequency | Less common | Can be frequent |
Time of onset | Daytime | Day or night |
Color | Pallor | Normal or cyanotic |
Aura | Dizziness, lightheadedness, blurred vision | A specific aura is possible |
Onset | Gradual (vasodepressor syncope), occasionally sudden | Sudden or with a short aura |
Autonomic phenomena | Frequent (vasodepressor syncope) | Uncommon |
Duration | Short | Short or prolonged |
Trauma | Rare | May occur |
Tongue biting | Rare, but may occur | Frequent, lateral part of the tongue (generalized tonic-clonic seizure) |
Sphincter incontinence | Rare, but may occur | Frequent |
Motor activity | Hypotonia, in convulsive syncope occasionally a short tonic contraction/a few clonic jerks | Variable, depending on the type of seizure |
Automatisms | No | Can occur in focal seizures; |
Recovery | Rapid | Often slow |
Postictal manifestations | Rare, but may occur | Occurs in generalized tonic-clonic seizures |
EEG appearance | Normal | Epileptiform changes |
Head-up tilt table test ("head-up tilt table test") | Positive | Negative |
Prolactin secretion | Rarely increased | Frequently increased in generalized tonic-clonic seizures; |

Can syncope be transmitted genetically?
Yes.
Is syncope a childhood condition, or can it persist for life?
Syncopal episodes can persist for life.
Can there be sequelae after a syncope episode?
The problems that appear after a syncopal event are those related to the trauma sustained at the moment of losing postural tone, and not to the syncope itself.
How can I tell that I'm about to have a syncope episode?
Most often, dizziness, a feeling of "lightheadedness", nausea or blurred vision precede syncope. Some people say they "see black in front of their eyes".
How can I prevent syncope?
Prolonged standing, sudden changes in position, and dehydration should be avoided, and it is recommended to keep regular mealtimes. It is recommended that standing up be done gradually, not suddenly.
What should I do when I feel that I'm about to have a syncope episode?
If the warning signs appear, the child should sit down, in order to avoid losing consciousness.
