Spectral electro encephalographic correlates of iron status tired blood revisited

Clinical reports have described impairment of affective and cognitive functions in Fe deficient persons. Brain biochemistry and cognitive performance capacity may be disrupted by inadequate intake of dietary Fe, but the relationship of the possible neurophysiological effects to psychological ones is unclear. To examine the relationship of Fe status to simultaneous measures of cortical activation and cognitive performance, 8 channels of EEG data were recorded during a resting period and during the performance of several cognitive tasks in 2 groups of men. The EEG data were spectrally analyzed; measures of total power and frequency of peak power in each of several bands of the power spectrum for each channel were used as predictors in multiple regression analyses with serum Fe and serum ferritin as alternative criteria. Measures of power in the delta frequency in the resting-period appeared relevant to Fe status in both groups, perhaps indicating alertness or arousal level. Consistently in these regressions, the asymmetry of the EEG appeared relevant to Fe and ferritin. The combination of EEG and performance measures may help characterize the neuropsychological effects of trace element nutrition.
