Insights

Children with traumatic brain injury (TBI) show larger cavum septum pellucidum (CSP) size, correlating with injury severity. These findings highlight potential brain morphometry changes following TBI.

Area of Science:

  • Neuroimaging
  • Neurodevelopmental disorders
  • Traumatic Brain Injury (TBI)

Background:

  • The cavum septum pellucidum (CSP) is a midline brain structure.
  • CSP presence is linked to neurodevelopmental disorders and head injuries.
  • Understanding CSP in youth with TBI is crucial for assessing injury impact.

Purpose of the Study:

  • To assess CSP presence and characteristics in youth with TBI.
  • To determine relationships between TBI severity, IQ, and CSP size.
  • To examine brain morphometry changes associated with CSP size.

Main Methods:

  • Magnetic Resonance Imaging (MRI) was performed on 98 TBI survivors and 34 controls.
  • CSP presence, size (length, volume), and grading were evaluated.
  • Correlations between CSP characteristics, injury severity, and IQ were analyzed.

Main Results:

  • No difference in CSP presence between TBI patients and controls.
  • TBI patients exhibited larger and more severely graded CSP.
  • CSP size positively correlated with TBI injury severity.
  • Right entorhinal cortex and bilateral hippocampus showed significant correlation with CSP size.

Conclusions:

  • CSP characterization in TBI youth reveals significant differences compared to controls.
  • CSP size is a potential biomarker for TBI severity.
  • Associated brain morphometry changes, particularly in the hippocampus, warrant further investigation.

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
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...
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
