What Causes Seizures in Babies?

Newborn seizures are caused by abnormal electrical discharges in the brain. These discharges are due to problems with the brain’s chemistry or nerve damage, in many cases, stemming from birth injuries. A birth injury is any sort of harm to a baby that occurs during or near the time of birth. It is important for parents to know that birth injuries can often be prevented. Moreover, a medical professional’s failure to prevent a birth injury may be grounds for a medical malpractice lawsuit.  

Some common birth injuries that can cause neonatal seizures are listed below:

  1. The most common cause of neonatal seizures is hypoxic ischemic encephalopathy (HIE) (1), which is a brain injury caused by a lack of oxygenated blood flow to the baby’s brain. HIE is often caused by an injury to the baby that takes place during or close to the time of labor and delivery. In addition to neonatal seizures, HIE can cause permanent brain damage and lifelong conditions such as cerebral palsy, developmental delays, and learning disabilities (2).
  2. Ischemic stroke is the second most common cause of neonatal seizure (1). An ischemic stroke is one caused by a clot in a blood vessel. Perinatal strokes (strokes around the time of birth) are often associated with HIE, traumatic birth, and other birth injuries (3).
  3. The third most prevalent cause of neonatal seizure is intracranial hemorrhages, or bleeding within the brain (1). These may include intracerebral hemorrhages and subarachnoid hemorrhages, among others. Brain bleeds can be caused by both HIE and traumatic birth injuries, i.e. when there is excessive force or pressure applied to a baby’s head during the process of labor and delivery (4).
  4. Infections such as sepsis and meningitis can also cause neonatal seizures (1). Maternal infections can be transmitted to the baby at birth, causing the baby to become infected. This is why it is especially important for doctors to do all they can to treat maternal infections and minimize the risk of transmission (5). If a baby has suspected seizures, they should be promptly evaluated for infection (1).  
  5. Hypoglycemia (low blood sugar) is another cause of neonatal seizures (1). This condition is common in babies born to mothers who have diabetes and babies who have hypoxic-ischemic encephalopathy and/or are small for gestational age (among other risk factors). Neonatal hypoglycemia is easy to diagnose and treat, but prolonged or undiagnosed hypoglycemia can cause permanent brain damage (6). Doctors should measure glucose levels in any infants with suspected seizures (1).

Can neonatal seizures be caused by medical negligence? Newborn Baby Dad

Neonatal seizures are often caused by birth injuries. In order to prevent birth injuries, medical professionals should perform regular prenatal tests to ensure the health of the baby. If any fetal distress is noted or there is a condition (e.g., preeclampsia) that can cause the baby to receive insufficient oxygen-rich blood, the baby should be placed under close observation and an early delivery may be indicated to prevent the baby from staying in suboptimal intrauterine conditions.

During labor and delivery, the baby’s heart rate should be continuously monitored with a fetal heart rate monitor. If a baby begins to experience oxygen deprivation, this will be reflected in the fetal heart tracings as “nonreassuring tracings.” Once nonreassuring tracings occur, medical professionals should intervene promptly. In many cases, this indicates delivery via emergency C-section. A delayed delivery can cause oxygen deprivation to be prolonged, resulting in HIE and seizures.

Listed below are high-risk conditions and birth injuries that can cause oxygen deprivation, HIE, and resultant neonatal seizures, especially if mismanaged by doctors and nurses (2).
