Use of automatic frequency analysis in the therapy of patients with acute ischemic insults

A series of EEG reading by automatic frequency analysis by means of Fast-Fourier transformation was taken, with a total of thirteen patients with acute ischemic infarction. Of the parameters under test, the total power-parameters, the relative performances of the delta and alpha wavebands, the delta/alpha index, and the alpha peak frequency variation proved their suitability in assessing clinical progress and in lateral localisation. Automatic frequency analysis adds to the range of tools available for EEG diagnosis, and can play its part in trend analysis during intensive therapy.
