Diagnosis by electroencephalographic topography.
In 5 patients, electroencephalographic (EEG) topography (Fourier analysis and topographic display of EEG data) demonstrated clinically significant acute brain lesions not seen by magnetic resonance imaging or computed tomography.  EEG topography contributed to patient management more than standard EEG.  Additional, carefully designed, prospective studies may indicate how frequently and in which settings EEG topography is a valuable diagnostic test.
