Lacunar stroke: mechanisms and therapeutic implications.

Area of Science:

• Neurology
• Cerebrovascular Diseases
• Small Vessel Disease

Background:

• Lacunar stroke is a significant subtype of ischemic stroke, accounting for up to 25% of cases.
• It serves as a critical indicator of cerebral small vessel disease.
• Understanding its underlying mechanisms is crucial for effective management and prevention.

Purpose of the Study:

• To provide a comprehensive overview of the potential mechanisms underlying lacunar stroke.
• To discuss the therapeutic implications derived from these identified mechanisms.
• To highlight recent advancements in stroke prevention strategies for lacunar stroke patients.

Main Methods:

• A narrative review of existing literature.
• Inclusion of randomized trials, exploratory comparative studies, and case series.
• Focus on recent studies detailing mechanisms and prevention strategies.

Main Results:

• Lacunar stroke is a heterogeneous condition with multiple underlying pathologies.
• The most common mechanism identified is lipohyalinosis.
• Less frequent mechanisms include atheromatous disease and cardioembolism.

Conclusions:

• A thorough evaluation of neuroimaging, cardiac, and systemic assessments is vital.
• Elucidating the pathomechanisms of neurological deterioration can guide novel therapeutic strategies.
• Optimizing short-term antithrombotic treatments may reduce neurological decline and prevent disability.
