Predisposing Factors, Pathologies, and Precipitating Factors Causing Intracerebral Hemorrhage

Area of Science:

• Neurology
• Vascular Medicine
• Epidemiology

Background:

• Hypertension is the primary risk factor for spontaneous intracerebral hemorrhage (ICH).
• However, ICH development is multifactorial, involving coexisting medical conditions and other predisposing factors.
• The term 'hypertensive ICH' is an oversimplification of complex causal pathways.

Purpose of the Study:

• To present a comprehensive framework for attributing causes of ICH.
• To integrate evidence on predisposing, underlying pathological, and precipitating factors.
• To support holistic clinical management and identify research gaps.

Main Methods:

• Systematic review of high-quality evidence.
• Integration of clinical experience.
• Development of a multifactorial causal framework for ICH.

Main Results:

• Existing ICH classification systems often overlook predisposing and precipitating factors.
• The proposed framework incorporates macrovascular, microvascular, and structural pathologies.
• Identifies knowledge gaps in the transition from predisposing factors to pathologies and ICH occurrence.

Conclusions:

• A multifactorial framework is essential for understanding ICH etiology.
• This framework aids clinical practice in holistic ICH treatment and prevention.
• Informs future research for a more comprehensive ICH classification system.
