Bromism, the chronic intoxication with bromide is rare and has been al
most forgotten. In the recent past bromide is rediscovered as an antic
onvulsive drug. The increasing frequency of bromism in children coming
to admission induced this report. We describe the cause, the symptoms
and the pseudohyperchloremia associated with bromism. If unclarified
neurological or psychiatric symptoms are associated with the determina
tion of an elevated serum chlorid concentration and a diminished anion
gap chronic intoxication with bromide has to be excluded.
