Autism Spectrum Disorder often comes with profound challenges in speech and communication. Families with children on the autism spectrum know the heartbreak of delayed language – the frustration of not hearing their child express needs or say simple words.

We stay current on emerging autism therapies, including nutritional and biomedical interventions like Leucovorin (folinic acid), which has recently gained national attention for its promising role in autism treatment.

What is Leucovorin?

Folate (vitamin B9) is crucial for brain development and function, supporting DNA synthesis, methylation, and neurotransmitter production. Some children with autism have issues in their folate metabolism, particularly a problem getting folate into the brain – a phenomenon known as cerebral folate deficiency. In many ASD cases, the immune system makes antibodies that block the folate receptor alpha (FRα) on brain cells. These folate receptor autoantibodies (FRAA) prevent folate from entering the brain normally, leading to low brain folate despite normal levels in the body. This blockage can especially impact speech and cognitive development.

Leucovorin (also called folinic acid) is a reduced, bioactive form of folate. It has a unique ability to use an alternate pathway into the brain. Even if the main folate receptors are blocked by antibodies, Leucovorin can enter the central nervous system through the reduced folate carrier (RFC), essentially bypassing the roadblock at the FRα. By using this “side door” into brain cells, leucovorin can restore folate levels in the brain and support normal neuronal functioning despite the antibody interference.

At Enliven Functional Medicine, we are always looking for innovative ways to better understand and support the children and families we serve. One of the tools available in our practice is FRAT® testing (Folate Receptor Autoantibody Test)—a specialized blood test that may uncover an important underlying factor in children with autism, speech delays, seizures, and other developmental challenges.

What is FRAT®?

FRAT® is a blood test that detects autoantibodies against folate receptor alpha (FRα). This receptor helps transport folate (vitamin B9) into the brain—an essential process for healthy brain development, neurotransmitter function, and cognition.

Why does it Matter?

Recent research shows that up to 75% of children with autism spectrum disorder (ASD) may have folate receptor autoantibodies. Identifying this issue can help target treatment more effectively. In such cases, addressing the deficiency may lead to meaningful improvements in communication, behavior, and overall development.

If you’re interested in exploring Leucovorin as a potential treatment for your child, our team at Enliven Functional Medicine can provide expert guidance. We take a personalized, integrative approach to ASD treatment, incorporating cutting-edge biomedical treatments alongside traditional therapies.
