FRAT positive means your son has antibodies blocking folate from reaching the brain (cerebral folate deficiency). Leucovorin (folinic acid) bypasses this block to deliver folate directly to the brain. MICOB SL (
B12 sublingual) supports nerve function alongside. This is a recognised treatment protocol for FRAT-positive ASD children â follow your neurologist's plan carefully.
Next Steps
Give medicines exactly as prescribed without missing doses. Continue ABA therapy, speech therapy and occupational therapy alongside medication. Results may take 3-6 months. Repeat FRAT test and brain MRI as advised. Consult me on Practo for general health queries about your son.
