Objective: Purpose of this study was to investigate the behavioral and brain activity im.airm.nts in patients after m.derate traum.tic brain injury (m.BI) in com.arison with the norm.l ranges while dual-tasks perform.ng. We would like to evaluate dual-tasking as diagnostic and rehabilitation tool and to test hypothesis of brain aging after m.BI. m.terial and m.thods: Electroencephalographic (EEG), stabilographic and clinical study was perform.d in 11 patients (m.an age 28.8 ± 8.4 years) for up to 1 - 12 m.nths after a m.BI in com.arison with 17 healthy subjects (26.7 ± 5.1 years). All the participants perform.d two m.tor and two cognitive tasks presented separately, and sim.ltaneously (dual-tasking). Results: Clinical exam.nation revealed predom.nantly cognitive deficit in m.BI patients with intact postural control. EEG data dem.nstrated coherence decrease for slow (delta-theta) rhythm. in frontal-tem.oral areas predom.nantly for left hem.sphere during cognitive tasks perform.nce. In contrast, EEG coherence for slow spectral bands increased in the sam. areas in healthy volunteers. EEG coherence increased for fast spectral bands—alpha2 and beta, predom.nantly in right hem.sphere while both healthy adults and patients perform.d m.tor com.onents of dual tasks. Rehabilitation course with dual tasks, led to a predom.nant reduction in cognitive deficits, and EEG coherence increases at the frontal-tem.oral areas of the left hem.sphere. Conclusions: Dual-tasks m.y be used as diagnostic tool in patients after m.BI. This approach dem.nstrates predom.nant cognitive deficit, and left hem.spheric dysfunction in patients sim.lar to elderly persons and support the hypothesis of brain aging after TBI. Pilot studies also suggested rehabilitation effect of dual-tasking in m.BI patients.
