Obraztsova et al, in a study involving 32 patients (21 with reversible and 11 with chronic Korsakov syndrome of traumatic origin) and 20 healthy controls, found that EEG beta activity (13-20 Hz) in the frontobasal and brainstem locations had negative prognostic significance in Korsakov syndrome. Most typically, patients with Korsakov syndrome have abnormal EEGs with slowing in the theta and delta frequencies. [31]
