Summary
Stroke is a chronic disease requiring long-term management. Non-invasive optical techniques show promise for assessing stroke during acute, subacute, and rehabilitation stages, aiding risk factor identification and secondary prevention.
Area of Science:
- Neurology
- Biomedical Engineering
- Medical Imaging
Background:
- Stroke is characterized by acute neurological deficits, but underlying cerebrovascular changes often precede the event by years.
- Stroke management necessitates a chronic disease perspective, including risk factor identification, and interventions across acute, subacute, and rehabilitative phases.
- Long-term rehabilitation is frequently required for persisting neurological deficits post-stroke.
Purpose of the Study:
- To review the application of non-invasive optical techniques in stroke assessment.
- To explore the integration of optical methods into the management of acute and subacute stroke.
- To outline the potential of optical techniques in stroke rehabilitation and secondary prevention.
Main Methods:
- Systematic review of experimental studies utilizing non-invasive optical techniques in stroke.
- Analysis of the utility of optical methods for monitoring dynamic pathophysiological processes.
- Evaluation of complementary roles of optical techniques alongside established diagnostic tools.
Main Results:
- Non-invasive optical techniques have been experimentally applied across all stages of stroke.
- These methods offer potential for assessing dynamic pathophysiological changes during acute and subacute phases.
- Optical techniques may enhance monitoring during rehabilitation and secondary prevention efforts.
Conclusions:
- Non-invasive optical techniques represent a promising complementary tool for comprehensive stroke management.
- Integration of optical methods can improve the assessment of pathophysiological processes throughout the stroke continuum.
- Further research is warranted to fully realize the potential of optical techniques in optimizing stroke care and prevention.

01:15Ischemic Stroke l: Introduction
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.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
