Summary
Lacunar ischemic lesions involve small perforating arteries, but large intracranial artery changes are increasingly recognized. Early diagnosis and neuroimaging are crucial for appropriate lacunar stroke treatment.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Lacunar ischemic lesions are associated with perforator artery pathology.
- Causes include embolism, hypoperfusion, and proximal large artery occlusion.
- Large intracranial artery disease is an emerging cause of lacunar strokes.
Purpose of the Study:
- To highlight the role of large intracranial artery disease in lacunar stroke.
- To emphasize the importance of comprehensive clinical and neuroradiological evaluation.
- To discuss potential endovascular treatment options for selected cases.
Main Methods:
- Review of clinical and neuroradiological findings in patients with lacunar syndrome.
- Analysis of etiological factors, including large artery disease.
- Consideration of differential diagnoses for lesions on CT/MR imaging.
Main Results:
- Large intracranial artery disease is a significant factor in some lacunar strokes.
- Advanced neuroimaging aids in identifying the cause and guiding therapy.
- Distinguishing true ischemic lesions from other pathologies on imaging is critical.
Conclusions:
- An integrated approach is necessary for diagnosing and managing lacunar stroke.
- Endovascular therapies may be applicable for certain patients with large artery involvement.
- Accurate differential diagnosis is essential to avoid misinterpreting imaging findings.

01:23Alzheimer Disease ll: Pathophysiology
42
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and...

01:22Cerebral Edema ll: Pathophysiology
31
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...

47
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...

3.5K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

01:15Ischemic Stroke ll: Pathophysiology
68
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...

35
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
