A preliminary study of the effect of pyridoxine administration in a subgroup of hyperkinetic children: a double-blind crossover comparison with methylphenidate.


A small sample of six patients with the putative "hyperkinetic syndrome" participated in a research protocol comparing administration of pyridoxine, methylphenidate, and placeboes. The children had had low whole blood serotonin levels and a history of previous responsiveness to methylphenidate. The results of the double-blind clinical evaluation showed trends suggesting that both pyridoxine and methylphenidate were more effective than placebo in suppressing the symptoms of hyperkinesis. Pyridoxine elevated whole-blood serotonin levels, methylphenidate did not. Clinical and laboratory evidence indicated that the pyridoxine effects persisted after the 3-week period when the vitamin had been given in this experimental design.
