Intracerebral hemorrhage: an update on diagnosis and treatment

Area of Science:

• Neurology
• Stroke Medicine
• Vascular Neurology

Background:

• Spontaneous non-traumatic intracerebral hemorrhage (ICH) is a severe stroke type with high mortality.
• It is primarily caused by small vessel diseases, including hypertensive arteriopathy and cerebral amyloid angiopathy (CAA).
• Current treatments and preventive strategies for ICH remain limited, leading to poor clinical outcomes.

Purpose of the Study:

• To review the etiology, diagnosis, treatment, management, and current clinical trials for intracerebral hemorrhage (ICH).
• To provide an updated understanding of ICH causes, pathophysiology, and diagnostic advancements.
• To discuss current and future therapeutic and preventive strategies for improving patient outcomes.

Main Methods:

• Comprehensive literature search on intracerebral hemorrhage (ICH).
• Review of studies on etiology, diagnosis, treatment, management, and clinical trials.
• Analysis of recent advances in neuroimaging biomarkers, genetic studies, and pathophysiological understanding.

Main Results:

• Significant progress has been made in understanding ICH causes and pathophysiology.
• New brain imaging biomarkers and genetic studies aid in diagnosis and classification.
• Acute interventions targeting hematoma expansion, hemoglobin toxicity, inflammation, edema, and anticoagulant reversal show promise.

Conclusions:

• Despite advances, clinical outcomes for ICH remain poor, highlighting persistent challenges.
• Rapid acute interventions, including medical therapies and minimally invasive surgery, are vital for improving short-term results.
• Improved classification of arteriopathies and prognosis will enable tailored prevention strategies, such as blood pressure control and optimized antithrombotic therapy, for better long-term outcomes.
