Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

24
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Cerebral Edema ll: Pathophysiology

19
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...

Cerebral Edema l: Introduction

30
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...

Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

20
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...

Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

21
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...

Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

30
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Area of Science:

  • Neuroscience
  • Immunology
  • Vascular Biology

Background:

  • Cerebral aneurysms (CAs) affect up to 5% of the US population.
  • CA rupture causes up to 7% of all strokes.
  • Pathophysiology of CA formation is not fully understood, but immune cells are implicated.

Purpose of the Study:

  • To review the role of the immune system in saccular cerebral aneurysm formation and progression.
  • To explore immune response modulation for treating aneurysms and preventing rupture.

Main Methods:

  • Review of existing studies on human CA specimens.
  • Analysis of experimental animal models of aneurysms.
  • Focus on inflammatory cell involvement in CA pathophysiology.

Main Results:

  • CA formation involves endothelial damage, elastic lamina degeneration, and inflammatory cell infiltration.
  • Hemodynamic stress can trigger endothelial damage and cytokine secretion, recruiting inflammatory cells.
  • Inflammatory cell infiltration leads to smooth muscle cell proliferation, apoptosis, and vascular wall remodeling.

Conclusions:

  • The immune system plays a critical role in cerebral aneurysm development and progression.
  • Modulating the immune response presents a potential therapeutic strategy for CA treatment and rupture prevention.
