Monogenetic Stroke Syndromes in Children and Young Adults

Area of Science:

• Neurology
• Radiology
• Genetics

Background:

• Stroke in pediatric and young adult populations is a significant cause of acquired disability.
• It is often underrecognized, despite its prevalence.
• Brain imaging, including CT and MRI, is crucial for diagnosis.

Purpose of the Study:

• To review characteristic CT and MRI findings in pediatric and young adult stroke patients.
• To associate specific imaging patterns with monogenetic (single-gene) causes of stroke.
• To improve early recognition of inherited conditions contributing to stroke.

Main Methods:

• Review of neuroimaging studies (CT and MRI) in pediatric and young adult stroke patients.
• Correlation of imaging findings with confirmed or suspected monogenetic disorders.
• Literature synthesis of characteristic imaging patterns associated with specific inherited stroke etiologies.

Main Results:

• Specific CT and MRI findings are indicative of underlying monogenetic stroke causes.
• Characteristic parenchymal and vascular imaging patterns can suggest inherited conditions.
• Early identification of these patterns facilitates timely genetic workup.

Conclusions:

• Neuroimaging plays a vital role in the comprehensive evaluation of young stroke patients.
• Familiarity with characteristic CT and MRI findings can lead to the early recognition of inherited stroke disorders.
• Prompt diagnosis of monogenetic causes allows for targeted management and genetic counseling.
