The Neurobiology of Chemotherapy-Induced Cognitive Impairment
In Brief
An observational study for Cognitive Symptoms. Completed, enrolled 28 participants across 1 site.
Detailed Summary
The investigators overall research hypothesis is that systemic chemotherapy induces structural changes in the white matter of the brain as demonstrated with Diffusion Tensor Imaging (DTI) and functional changes in well-defined cortical neural networks as demonstrated by resting-state functional connectivity MRI (rs-fcMRI). The investigators believe these structural and functional changes are responsible for the cognitive symptoms associated with chemotherapy-induced cognitive impairment (CICI). The Specific Aim for this study is: To assess the impact of chemotherapy on structural white matter as defined by DTI and functional cognitive networks as defined by rs-fcMRI by comparing a sample of breast cancer survivors with self-reported CICI to breast cancer survivors without CICI. Hypothesis: Post-chemotherapy breast cancer patients with self-reported CICI will have abnormal structural connections characterized by DTI-defined disruptions in fractional anisotropy (FA) and mean diffusivity (MD) and abnormal functional connectivity characterized by rs-fcMRI-defined disruptions in cognitive networks when compared to patients without self-reported CICI.
