Stroke: Introduction and Types

75
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...

Ischemic Stroke l: Introduction

57
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: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

74
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: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

57
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...

Background:

  • Thermography is a non-invasive diagnostic method measuring skin temperature.
  • It reflects underlying physiological states, aiding in disease assessment.
  • This review focuses on thermography's role in stroke diagnosis and management.

Purpose of the Study:

  • To systematically review the clinical utility of thermography in stroke.
  • To evaluate its application in diagnosing and monitoring stroke patients.
  • To emphasize its potential clinical applications in neurology.

Main Methods:

  • Systematic review adhering to PRISMA guidelines.
  • Screening of three databases up to end of 2024.
  • Included 20 studies after assessing 277 records, with risk of bias evaluation.

Main Results:

  • Thermography shows potential in acute stroke for detecting carotid occlusive disease via temperature differences.
  • It aids in the differential diagnosis of specific stroke types like Wallenberg syndrome.
  • In chronic stroke, thermography assists in monitoring rehabilitation progress.

Conclusions:
