title: Electroencephalography in tetanus.
abstract: To assess the brain involvement caused by tetanus, we examined the EEGs of 39 patients recovered from tetanus and those of 39 sex- and age-matched controls. The patients had significantly more frequent and more severe EEG abnormalities than their controls. The most marked difference was in the occurrence of diffuse EEG abnormalities (P less than 0.05). Twenty patients had normal EEGs. EEGs of 14 patients (5 of whom in this follow-up) during acute tetanus showed abnormalities in 10 patients, marked in degree in 3 of those. EEG abnormalities started to improve after the acute phase of tetanus. It is concluded that EEGs of patients with tetanus are often abnormal and that EEG is helpful in revealing brain involvement in patients after tetanus.
