Spectral power, source localization and microstates to quantify chronic deficits from 'mild' closed head injury: correlation with classic neuropsychological tests.
Corradini PL1, Persinger MA.
Abstract
PRIMARY OBJECTIVE:
To explore the quantitative relationship between neuropsychological impairment and spectral QEEG power, source localization (s-LORETA) and microstate duration in patients who 'fail to adapt' years after mild closed head injury.
METHODS AND PROCEDURES:
Differences in classic psychometric measures, QEEG measures, s-LORETA indicators and microstate durations were compared for three levels of neuropsychological impairment ∼(average) 6 years after injury.
RESULTS:
Patients who displayed the moderate-to-severe neuropsychological impairments typical of mild TBIs exhibited shorter microstates, less power within the alpha band and lower power within the theta and delta bands within caudal regions. There were conspicuous differences in the configurations of microstates, their source localizations and frequency bands.
CONCLUSIONS:
The systematic relationship between neuropsychological impairment as inferred by classic psychometric measures that can require tens of hours to collect and modern configurational analyses of brain activity that require ∼30 minutes suggests that the latter might be useful in discerning the area of dysfunction and potential focus of treatment for patients with closed head injury years after the event.
