Spectral power was calculated for delta (1\u20134 Hz), theta (4\u20138 Hz), alpha (8\u201312 Hz), beta (12\u201325 Hz), and high beta (25\u201330 Hz) bands across frontal, central, and posterior regions. Group differences were assessed using generalized estimating equations, and Pearson correlation analyses were conducted to examine associations between electroencephalography activity and clinical symptoms.Results PD patients showed significantly higher high beta power across all regions compared to HC (frontal: estimate=1.276, \u03c7\u00b2=12.48, p&lt;0.0010; central: estimate=0.874, \u03c7\u00b2=9.87, p=0.0017; posterior: estimate=0.524, \u03c7\u00b2=4.48, p=0.0343). Beta power was elevated only in the frontal region (estimate=3.391, \u03c7\u00b2=5.31, p=0.0212), while delta power was increased overall (\u03c7\u00b2=4.60, p=0.0390) without regional specificity. No significant group differences were observed in alpha or theta bands. A significant positive correlation was found between frontal high beta power and Panic Disorder Severity Scale scores (r=0.41, p=0.010), while no other significant correlations were observed between regional high beta power and clinical scales.Conclusion Increased high beta, beta, and delta activity in PD may reflect a neurophysiological imbalance. In particular, elevated high beta power may indicate hyperarousal and excessive cognitive control in PD, suggesting its potential as a future biomarker.<\/jats:p>","DOI":"10.30773\/pi.2025.0141","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T23:40:25Z","timestamp":1770162025000},"page":"270-277","update-policy":"https:\/\/doi.org\/10.30773\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Quantitative
