Implication

Combined human imaging and animal model studies reveal cognitive deficits and brain iron deposition in thalassemia patients, indicating the need for early intervention.

Key Points

To investigate brain injury and iron deposition patterns in thalassemia patients using multimodal evaluation methods.
Enrolled 88 thalassemia patients and 79 healthy controls
Utilized resting-state functional magnetic resonance imaging (rs-fMRI) for neural activity assessment
Conducted cognitive evaluations with Mini-Mental State Examination and Montreal Cognitive Assessment
Analyzed brain iron content through quantitative susceptibility mapping and serum ferritin
Developed an iron overload mouse model for comparative analysis.
Significant cognitive impairments identified in attention, memory, and language among thalassemia patients
Elevated brain iron levels in subthalamic nucleus and globus pallidus
Iron accumulation observed in the choroid plexus of the murine iron overload model
S100B and NSE levels increased in thalassemia patients, indicating brain injury
Stronger correlations in TM patients between serum ferritin and cognitive impairments.
