ASSESSMENTS ON ALPHA WAVE CHARACTERISTICS IN ELECTROENCEPHALOGRAPHY OF ISCHEMIC STROKE PATIENTS WITH INSOMNIA
Main Article Content
Abstract
Objective: Study on the changes in alpha waves on electroencephalography in ischemic stroke patients with insomnia. Subjects and research methods: Prospective and cross-sectional descriptive study at the Stroke Department and Functional Diagnosis Department, Military Hospital 103, was carried out from June 2023 to July 2024. Results: In ischemic stroke patients with insomnia, there were disappearances of spindle-shaped alpha waves; there were reductions in Alpha waves’s amplitude median at the F3-C3, C4-P4, P4-O2, O2-T4, and T4-Fp2 leads; there were reductions in Alpha waves’s index median at the F3-C3, T3-Fp1, P4-O2, and T4-Fp2 leads, with statistical significance (p < 0.05). Conclusion: The changes of alpha waves were characterized by a decrease in amplitude and index observed in ischemic stroke patients with insomnia.
