Brain Cognitive Network Abnormalities in Anemia Patients Using fNIRS (AN-CNA)
Construction of Abnormal Projection Regions of Cognitive Neural Networks in Patients With Anemia Using Functional Near-Infrared Spectroscopy (fNIRS)
Anemia is a global public health concern and is closely linked to dysfunction of brain cognitive neural networks, a key mechanism underlying cognitive impairment. Such deficits-including declines in memory, learning, processing speed, and executive function-reduce daily living abilities and increase risks of falls and depression.
Functional near-infrared spectroscopy (fNIRS) enables real-time monitoring of oxygenated and deoxygenated hemoglobin fluctuations, reflecting brain network function. This study aims to identify affected neural network regions in anemic patients and visualize connectivity changes using heatmaps and arc-based mapping. The findings will support early detection of cognitive impairment and guide precise clinical interventions, ultimately informing individualized treatment strategies to enhance therapeutic outcomes and quality of life.

|
Patients will be assessed within 48 hours of admission.
|
|
Sleep quality
기간: Patients will be assessed within 48 hours of admission.
|
The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality, with a higher global score indicating poorer sleep quality.
The global score range is 0-21.
