A clinical approach to arterial ischemic childhood stroke: increasing knowledge over the last decade

Area of Science:

• Pediatric Neurology
• Neurovascular Diseases
• Child Health

Background:

• Childhood stroke is a significant health concern with substantial impacts on children, families, and socioeconomic factors.
• Delayed diagnosis is common due to diverse symptoms and conditions mimicking stroke in children.
• Neurological deficits and cognitive/behavioral problems are frequent sequelae in affected children.

Purpose of the Study:

• To highlight the importance of recognizing childhood stroke.
• To discuss diagnostic challenges and key risk factors.
• To review current understanding of pediatric stroke etiology, diagnosis, and outcomes.

Main Methods:

• Clinical observation and review of diagnostic approaches for childhood stroke.
• Emphasis on neuroimaging, particularly diffusion-weighted magnetic resonance imaging (MRI), as the gold standard.
• Analysis of common etiological factors including infectious/parainfectious conditions, arteriopathies, and coagulopathies.

Main Results:

• Hemiparesis is the most common symptom, but others like ataxia and seizures also occur.
• Infectious/parainfectious etiologies and arteriopathies (FCA, dissection, MoyaMoya) are key risk factors.
• Cardiological issues and hereditary coagulopathies also contribute to stroke risk.
• Treatment remains controversial, with antiplatelet agents and heparinization commonly used; thrombolysis is under consideration.
• Two-thirds of children experience significant residual neurological deficits, with cognitive and behavioral issues prevalent.

Conclusions:

• Prompt neuroimaging is essential for diagnosing childhood stroke.
• Identifying underlying risk factors aids in clinical suspicion and management.
• Pediatric stroke often leads to long-term neurological and cognitive impairments, necessitating comprehensive care.
