Implication

Randomized trial investigates the relationship between brain iron levels, cortical atrophy, and cognitive impairment in CAA, suggesting complex interactions.

Key Points

This study aims to determine the role of cortical atrophy in the relationship between iron deposition and cognitive impairment in cerebral amyloid angiopathy.
Enrolled 44 patients with cerebral amyloid angiopathy
Conducted cognitive assessments and magnetic resonance imaging
Used elastic net analysis and mediation analysis to explore relationships between iron levels and cognitive functions.
Iron accumulation in specific brain regions was linked to worse cognitive performance, especially in the left posterior cingulate gyrus (β = -0.156, p = 0.002)
Cortical atrophy did not mediate the relationship between iron deposition and cognitive dysfunction (p = 0.77).
