Insights

Perinatal factors like infection and brain bleeds increase seizure risk in very low birthweight infants with periventricular leukomalacia. Sepsis and necrotizing enterocolitis significantly elevate this risk.

Area of Science:

  • Neonatal neurology
  • Pediatric neurology
  • Perinatal medicine

Background:

  • Periventricular leukomalacia (PVL) is a common brain injury in preterm infants.
  • Seizures are a significant complication in infants with PVL, impacting neurodevelopmental outcomes.
  • Identifying perinatal risk factors for seizures in this population is crucial for timely intervention.

Purpose of the Study:

  • To determine perinatal factors associated with seizures in very low birthweight infants diagnosed with periventricular leukomalacia.
  • To analyze the relationship between specific clinical variables and seizure occurrence in this vulnerable infant group.

Main Methods:

  • Population-based observational study utilizing the Israel National Very Low Birthweight Infant Database.
  • Included 545 infants (gestational age 24-36 weeks) surviving beyond 28 days with diagnosed PVL.
  • Statistical analysis included chi-square tests, univariate analysis, and logistic regression to identify independent predictors of seizures.

Main Results:

  • 18.7% (102/545) of infants with PVL experienced seizures.
  • Independent predictors of seizures included lower gestational age, intraventricular hemorrhage, post-hemorrhagic hydrocephalus, sepsis, and necrotizing enterocolitis.
  • Concomitant sepsis and necrotizing enterocolitis increased seizure risk 4.6-fold.

Conclusions:

  • Gestational age, intraventricular hemorrhage, post-hemorrhagic hydrocephalus, sepsis, and necrotizing enterocolitis are significant predictors of seizures in very low birthweight infants with PVL.
  • Infection, particularly sepsis and necrotizing enterocolitis, may play a critical role in the pathogenesis of brain injury and subsequent seizures in preterm infants.
  • These findings highlight the importance of monitoring for and managing these complications to potentially reduce seizure incidence.

Seizures: Classification01:13

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...
Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
