Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

44
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Ischemic Stroke ll: Pathophysiology

54
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...

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
  • Pharmacology

Background:

  • Cannabinoids are being investigated for neurodegenerative disease treatment.
  • The endocannabinoid system's role in the brain suggests therapeutic potential.

Purpose of the Study:

  • To review current data on using cannabis constituents for neurological disorders, specifically ischemic stroke.
  • To highlight disparities in findings and summarize advancements in cannabinoid research for stroke.

Main Methods:

  • A narrative review of selected articles.
  • Summarizing study designs, results, limitations, and conclusions.

Main Results:

  • Cannabinoid receptor distribution in brain structures involved in myelination suggests stroke benefits.
  • Varied compounds, administration routes, dosages, and timing hinder direct data comparison.
  • Limited studies, particularly in stroke patients, restrict definitive conclusions.

Conclusions:

  • The literature review indicates potential benefits of cannabinoids for ischemic stroke.
  • A pragmatic approach to clinical cannabinoid use in stroke patients is discussed.
