[Research progress on periventricular white matter damage pathogenesis in preterm infants]
1Children's Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China.
Summary
Periventricular white matter damage in preterm infants, a key encephalopathy, involves oligodendrocyte and axonal injury. Understanding its pathogenesis aids in clinical prevention and treatment strategies.
Area of Science:
- Neurology
- Neonatology
- Pathology
Context:
- Periventricular white matter damage is a hallmark of brain injury in preterm infants.
- It represents the most significant form of encephalopathy in this vulnerable population.
Purpose:
- To review and synthesize current research on the pathogenesis of periventricular white matter damage in premature infants.
- To provide a theoretical foundation for clinical strategies in prevention, diagnosis, and treatment.
Summary:
- Pathological changes include coagulation necrosis, oligodendrocyte and myelin damage, axonal injury, and glial cell infiltration.
- Immature cerebral vasculature and oligodendrocyte precursor vulnerability to hypoxia, ischemia, infection, free radicals, inflammatory cytokines, and glutamate contribute to the damage.
- These lesions are strongly linked to neurological sequelae in the later neonatal period.
Impact:
- Enhances understanding of the complex mechanisms underlying brain injury in preterm neonates.
- Offers potential for improved diagnostic and therapeutic interventions for periventricular white matter damage.
- Supports the development of targeted strategies to mitigate long-term neurological deficits in premature infants.

01:22Cerebral 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...
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
