Rodent models of hemorrhagic stroke

Area of Science:

• Neurology
• Translational Medicine
• Animal Models

Background:

• Intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) result in high mortality and severe disability.
• Current treatments for ICH are lacking, and SAH therapies require significant improvement.
• Understanding pathophysiologic mechanisms is vital for developing novel therapeutic strategies for hemorrhagic stroke.

Purpose of the Study:

• To review and discuss existing rodent models of ICH and SAH.
• To compare the similarities and differences among various hemorrhagic stroke models.
• To provide insights into selecting appropriate models for research.

Main Methods:

• Literature review of established animal models for ICH and SAH.
• Comparative analysis of model characteristics, modifications, and applications.
• Discussion on the relevance of different models for clinical translation.

Main Results:

• Multiple rodent models exist, each reliably mimicking specific aspects of ICH and SAH.
• Models vary in their ability to replicate the complexity of human hemorrhagic stroke.
• Key considerations for choosing a suitable model are highlighted.

Conclusions:

• Animal models are indispensable tools for advancing the understanding and treatment of hemorrhagic stroke.
• Careful selection of appropriate models is critical for successful research and therapeutic development.
• Further research using refined models can bridge the gap between preclinical findings and clinical application.
