Summary
New cerebral microbleeds (CMBs) may acutely develop in patients experiencing refractory status epilepticus (SE). This finding is novel, as CMBs were previously unreported in SE cases.
Area of Science:
- Neurology
- Neuroimaging
- Critical Care Medicine
Background:
- Cerebral microbleeds (CMBs) are associated with stroke and cerebral amyloid angiopathy.
- CMBs have not been previously reported in patients with status epilepticus (SE).
Observation:
- Two previously healthy patients presented with refractory SE of unknown origin.
- Initial neuroimaging revealed no evidence of CMBs in either patient.
- Follow-up susceptibility-weighted imaging showed the acute development of numerous CMBs (63 and 14) in the two patients.
Findings:
- Refractory SE is associated with the potential for acute development of multiple CMBs.
- Multimodal neuromonitoring indicated significant physiological disturbances, including altered brain metabolism and impaired cerebrovascular regulation.
Implications:
- This study highlights a potential novel complication of refractory SE.
- Further research is warranted to understand the mechanisms and clinical significance of CMBs in SE.
- These findings may influence diagnostic and management strategies for patients with refractory SE.

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...
01:29Hemorrhagic Stroke ll: Pathophysiology
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...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
