Study suggests a derivative of vitamin B9 improves language skills in autistic children
FOLINIC acid, a drug derived from folic acid (a synthetic form of vitamin B9), could improve autistic children’s ability to communicate, according to a study published in the journal Molecular Psychiatry.
Previous studies have shown that women who take folate supplements before conception and during pregnancy lower their risk of having a child with autism.
Vitamin B9 (folic acid) plays an important role in the formation of red blood cells, the nervous system, the immune system, and wound healing. It is required for the production of new cells, which makes it particularly important during periods of embryonic and foetal development
We know, for example, that before conception and during the first trimester of pregnancy, B9 helps to protect the child from conditions such as spina bifida, harelip and heart problems, and it decreases the risk of miscarriage.
One major folate food source is plant leaves. It is also found in brewer’s yeast, green vegetables (spinach, cabbage, salad leaves), seeds such as corn and chickpeas, liver, lentils and seaweed.
According to this latest study, folinic acid, which is a reduced form of folic acid, could improve children’s ability to communicate and express themselves through language.
The researchers followed 47 children, with an average age of seven, who had autism spectrum disorders (ASDs) or communication difficulties for 12 weeks. The first group took a high dose of folinic acid (2mg/kg, up to 50mg per day) and the second group were given a placebo.
The study was able to identify specific blood markers which can predict treatment response in children with autism and verbal communication difficulties. The findings showed that the participants with folate receptor autoantibodies had a more favourable response to the folinic acid treatment.
Verbal communication was much improved in the participants who took folinic acid when compared with those who were given the placebo.
The harmful effects of these folate receptor autoantibodies on brain development and function have been confirmed in a laboratory rat model.
These promising, preliminary findings have encouraged the researchers to envisage a larger-scale study of the effects of high-dose folinic acid as a treatment for autistic spectrum disorder.children.
