The clinical picture of salicylate-poisoning is characterized by neuro
logical symptoms reaching from mental slowing, confusion, hallucinatio
ns to convulsions, We describe a patient, who showed EEG abnormalities
in the form of mild diffuse slowing with additional intermittent slow
activity on repeated admissions, These abnormalities rapidly disappea
red together with the clinical symptoms of mental slowing, ataxia, dys
arthria and confusion. Eventually, a chronic salicylate intoxication w
as revealed. It is suggesed that EEG abnormalities serve as an additio
nal diagnostic clue in this potentially fatal condition.
