Neonatal Seizures (Infant Seizures) and Birth Injury

Neonatal seizures can be very difficult to recognize. This page contains general information about seizures but is not meant to be used as a diagnostic tool. Also, we cannot provide medical advice. We are not doctors, and our live chat service should not be used for medical emergencies.

If you think that your child is currently having or has recently had a seizure for the first time, please call 911 for immediate medical attention. Infant seizures are serious conditions and require the care of a medical professional.

Seizures are involuntary jerking movements, caused by abnormal electrical patterns in the brain from brain damage or problematic neurochemistry. Neonatal seizures – seizures in a baby – are often subtle and difficult to identify. They can be caused by a number of factors, including hypoxic-ischemic encephalopathy (HIE), infections, trauma, and prolonged labor and delivery. HIE and fetal oxygen deprivation are the most common causes. Neonatal seizures can also worsen existing brain damage.

Infant Seizures and Birth Injury


What Are Neonatal Seizures?

Seizures occur from abnormal electrical discharges in the brain, which are due to nerve damage or problems with the brain’s chemistry. Seizures can cause involuntary jerking movements lasting from a few seconds to a few minutes and can affect normal brain functioning. They sometimes affect consciousness. Seizures must be immediately diagnosed and properly treated in newborns in order to prevent permanent damage to the baby.

Seizures in newborns are categorized as subtle, clonic, tonic, or myoclonic:

  • Subtle seizures, as the name implies, are often difficult to see. They comprise about 50% of all newborn seizures and are especially frequent in premature infants. There may be some bicycling-type movement, fixation of gaze, or repetitive facial movements.
  • Clonic seizures in infants are marked by a slow rhythmic jerk of one part of the body. This type of seizure represents about 25% of all seizures in newborns.
  • Myoclonic seizures involve rapid twitching or jerking movements and are often the most serious type of neonatal seizure. Myoclonic seizures may indicate severe brain damage. Premature babies are the most afflicted group.
  • Tonic seizures account for about 5% of infant seizures and cause sustained contractions. Sometimes the eyes may roll upward and breathing may stop for a period of time.

Causes of Neonatal Seizures

Seizures can be caused by a number of things, including:

Seizures From HIE (Hypoxic-Ischemic Encephalopathy)

Hypoxic ischemic encephalopathy (HIE or birth asphyxia) is the most common cause of neonatal seizures, with an estimated 80% of cases attributed to HIE. HIE is a medical condition in which a newborn has been deprived of oxygen at or around the time of birth. Some of the medical emergencies that could result in HIE and seizures include cord compression, problems with the placenta or uterus such as a ruptured uterus or placenta previa, fetal distress, and prolonged labor. Medical staff must plan appropriately for these kinds of obstetrical risks. Furthermore, they must effectively handle situations that may arise during delivery in order to minimize the possibility of HIE. Failure of doctors or other healthcare professionals to do these things could be considered negligence.

Seizures From Infection

The most common infections occurring in newborns that can cause seizures are meningitis, Group B Streptococcus, encephalitis, cytomegalovirus and herpes simplex virus. While infants may become infected after delivery, the most common cause of neonatal infection is an undetected and untreated infection in the mother that is transmitted to the baby through the birth canal. It is the doctor’s or other healthcare provider’s responsibility to screen for various infections during the pregnancy and appropriately treat them.

Seizures From Traumatic Brain Injury

Traumatic birth injuries can result from a problem with the size or position of a fetus relative to the birth canal. For example, sometimes a baby’s head is too large for the mother’s pelvis (cephalopelvic disproportion) or the baby may just be very large (macrosomic). Again, it is the responsibility of the doctor or another healthcare provider to prenatally check and plan for these types of obstetrical problems. Traumatic brain injuries can also occur from the use of instruments like forceps or vacuum extractors during vaginal deliveries. Forceps resemble tongs. Proper placement requires that the “blades” lie evenly against a baby’s head in a location where they are not likely to cause damage. If the forceps are applied unevenly to the baby’s head, skull and facial fractures as well as intracranial hemorrhages, seizures, and permanent brain damage can occur.  Vacuum extractors, as the name implies, use suction to pull a baby from the birth canal during a contraction. A small plastic cup is attached to the infant’s head. If it is not correctly placed, bruising, hemorrhages and blood clots can occur. Doctors and other healthcare providers must use forceps and vacuum extractors correctly and at the right stage of labor in order to avoid irreparable damage.

Seizures From Prolonged Second Stage of Labor

The second stage of labor occurs from the time the mother is fully dilated until the baby is delivered. When this time lasts more than four hours, it is considered to be a prolonged second stage. A prolonged second stage is most often associated with cephalopelvic disproportion. A C-section should be done to minimize the risks of brain injury. Failure to perform a timely C-section may be considered negligence.


Diagnosing Neonatal Seizures

The primary diagnostic test for verifying seizure activity and determining the part of the brain affected is an EEG. In an EEG, electrodes are temporarily attached to the baby’s head. The electrodes read the electrical activity of the brain and show the changes that occur over time. The results appear on-screen as well as on printed strips.


What Do You Do if a Baby Has a Seizure?

If a baby has a seizure, it’s imperative to get them medical care. When parents first identify a seizure, they should:

  • Place the baby on a soft surface and make sure they are safe.
  • Loosen the baby’s clothing.
  • Keep everything away from the baby’s mouth.
  • Prevent choking by putting them on their side or stomach.
  • Make sure the baby is breathing.
  • Keep the baby’s airway clear by wiping away saliva and debris from the mouth.
  • Time how long the seizure lasts.
  • If your baby has a history of seizures, administer anti-seizure medication prescribed by the doctor.
  • If possible, get a video recording of the seizure to show the doctor
  • Seek help from your child’s pediatrician or emergency room as soon as possible to help identify the underlying cause of the seizures

Many parents want to know under which circumstances they should call 911 if their child is having a seizure. This depends on individual health circumstances, including what type of seizure they are having. If a child is having their first ever seizure, parents should always call 911. After the initial seizure, you can talk to your child’s doctor about the circumstances under which you should seek emergency medical attention for possible future seizures. The doctor’s advice should be based on individual factors (such as the type of seizure they have had), and may be different for different patients.

The CDC website recommends seeking medical attention if any of the following are true. Please keep in mind that these are very general recommendations, and your child’s doctor may tell you additional signs to watch out for.

  • This is the person’s first seizure
  • The seizure lasts more than five minutes
  • The person has two seizures closely spaced together
  • The person is struggling to breathe or not waking up after the seizure is over
  • The person is hurt during the seizure (for example, if they hit their head on a hard surface)
  • The seizure occurs in water
  • The person has a health condition like diabetes or heart disease (pregnancy also qualifies)

If you have any medical concerns about your baby – such as seizures – please seek medical attention immediately. Neonatal seizures are a condition that must be evaluated by a medical professional.
