Background and Purpose.
Recent studies suggest that abnormal structure and function in the brain network were related to cognitive and emotional impairment in hyperthyroid patients (HPs).
The association between altered voxel-mirrored homotopic connectivity (VMHC) and neuropsychological impairment in HPs remains unclear.
This study is aimed at investigating the association between the disrupted functional coordination and psychological dysfunction in hyperthyroidism.
Method.
Thirty-three hyperthyroid patients and thirty-three matched healthy controls (HCs) were recruited, and they received resting-state functional magnetic resonance imaging (fMRI) scans and neuropsychological evaluation.
The VMHC value was computed to reveal the functional coordination between homotopic regions in both groups.
The neurobehavioral relevancy method was employed to explore the relationship between the altered VMHC and emotional, cognition measures.
Further receiver operating characteristic (ROC) curve analysis was adopted to examine the power of changed regional VMHC in classifying the patients with hyperthyroidism.
Results.
Compared with the HCs, the HPs exhibited significantly declined VMHC values in the bilateral medial frontal gyrus (MeFG).
The interhemispheric asynchrony in the MeFG was positively correlated with Z scores of episodic memory.
The ROC analysis further determined that abnormal VMHC in the MeFG could efficiently distinguish the HPs from the HCs (area under the curve AUC=0.808, P<0.001).
Conclusion.
The altered interhemispheric coordination in the hub of the default mode network may implicated in the modulation of episodic memory in HPs patients and the distinct feature of the interhemispheric asynchrony may be treated as a potential target for the early recognition and intervention for the HPs with cognitive impairments.
Clinical Trial Registration.
This is a study of the neurological basis for dysfunction of mood and cognition in hyperthyroid patients: a resting-state fMRI study (registration number: ChiCTR-OOC-16008607).
