Primary
| Measure | Time frame |
|---|---|
| Main Objective: The main objective of this study is to evaluate the efficiencyof folinic acid, as folinate calicum (FOLINORAL®) 5 mg two times a day during 12 weeks, on the reduction of autism disorder especially on the communication and social interactions.;Secondary Objective: 1)Evaluate the efficiencyof folinic acid on autistic symptoms reducing perceived by parents. 2)Assess the consistency of the anti-receptor antibody levels folate FRa in autistic children 12 weeks after starting treatment. 3)Studying the relationship between the presence of antibodies anti-folate receptor FRa before treatment and the response to folic acid treatment 12 weeks after. 4)Safety evaluation of folinic acid in the 12 weeks of treatment and at the end of this research.;Primary end point(s): Difference of the score obtained by the ADOS scale, for "communication" and "social interaction" items, between baseline visit (T0) and 12 weeks of treatment visit (S12) in the 2 groups (placebo and folinic acid).;Timepoint(s) of evaluation of this end point: 12 weeks | — |
