Key Points

The aim is to identify unique qEEG characteristics that differentiate cognitive from headache phenotypes in TBI.
Utilized quantitative EEG to analyze brain activity patterns among TBI patients with headaches and cognitive issues.
Employed specific metrics to examine spectral features in EEG data for distinct phenotypes.
Identified significant differences in the 1/f and power spectral characteristics between cognitive and headache phenotypes.
Statistical analysis confirmed the distinct EEG patterns, suggesting their potential utility in clinical assessments.

Investigates distinct EEG features in cognitive and headache phenotypes of TBI, indicating potential diagnostic implications.

To investigate if cognitive and headache traumatic brain injury (TBI) phenotypes exhibit distinct quantitative EEG (qEEG) features.
