[Biochemical studies in stuttering in children].

Selected biochemical investigations were performed in 53 stuttering children aged 5-12, and in control group of 22 clinically healthy, non-stuttering children aged 6-16. Sodium, potassium, calcium and magnesium ions in the serum were determined according to the pharmacopoeia++ "Zweites Arztneimittelbuch++ der DDR (1983)". A special anamnestic questionnaire helped to exclude metabolic diseases and/or gastro-intestinal disorders. As a result of the study, significant differences between the Mg-ion concentrations in both groups could be demonstrated. In 47% of the stuttering children studied, hypomagnesaemia was found. This result provides interesting aspects for further investigations concerning medicamentous therapeutic concepts.
