Research Abstract |
To investigate the factors that predict vitamin B6 responsiveness in children with autism, we conducted an intervention study and 17 children have participated. They all completed the neurological and blood tests before and after the intervention. In the first 2 weeks, vitamin B6 was given in doses of 5mg/kg. In the following 2 weeks, vitamin B6 was given in doses of 10mg/kg. Among the participants, 3 cases were judged as "effective". We compared the characteristics and biomarkers between "effective" group and "ineffective" group. We found that simultaneously having "hypersensitivity to sound" and "clumsiness" or "low plasma concentration of glutamine" predicted the vitamin B6 responsiveness.
