Abstract

Objective: To describe the characteristics of theta wave amplitude and some related factors in hemodialysis patients. Methods: A total of 120 patients undergoing hemodialysis were examined for EEG from June 2023 to May 2024 at Military Hospital 103. Theta wave amplitude (4–7 Hz) was analyzed in prefrontal, frontal, central and temporal regions of both hemispheres. Results: Theta wave amplitudes in the prefrontal, central, frontal and temporal regions of the left hemisphere were 47.0, 33.7, 32.9 and 24.3 µV, respectively. Theta wave amplitudes in the right prefrontal, frontal, central, and temporal regions were 47.6, 33.7, 32.7, and 26.5 µV. Reduced theta wave amplitude were found in the left prefrontal, frontal, and central regions and in the right prefrontal and temporal regions in the group of subjects with their age > 60 years old. Theta wave amplitude in the left hemisphere of the frontal region was negatively correlated with BMI. In contrast, theta wave amplitude in the left temporal temporal region was positively correlated with dialysis time. Conclusion: Increased theta wave amplitude was observed in hemodialysis patients. Age, BMI and dialysis time are factors that affect theta wave amplitude in dialysis patients.
