FDA Doesn’t Endorse Leucovorin for Autism, OKs It for Rare Brain Disorder

**New Treatment Option for Rare Neurological Disorder**

The US Food and Drug Administration (FDA) has approved the use of leucovorin to treat cerebral folate deficiency, a rare neurological disorder characterized by low levels of vitamin B9 in the brain. This approval marks a significant milestone for patients living with this condition.

What is Cerebral Folate Deficiency?

Cerebral folate deficiency is a rare genetic condition that affects approximately 1 in 1 million people worldwide. It can cause developmental delays, seizures, and movement abnormalities. Research suggests that up to 38-70% of autistic children may have cerebral folate deficiency, although the true prevalence is unknown.

What is Leucovorin?

Leucovorin is a prescription medication primarily used to alleviate the side effects of chemotherapy. It works by restoring folic acid to healthy cells that have been depleted by chemotherapy. The FDA has now approved leucovorin as a treatment for cerebral folate deficiency, providing relief for individuals with this condition.

Important Considerations

While the approval of leucovorin is significant, experts emphasize that more research is needed to determine its effectiveness as an autism treatment. The FDA has not approved leucovorin for this purpose, and any claims suggesting otherwise are unsubstantiated.

Expert Insights

Alycia Halladay, MD, Chief Science Officer of the Autism Science Foundation, notes that early intervention with leucovorin is key to treating cerebral folate deficiency. Antonio Hardan, MD, Professor of Psychiatry and Behavioral Sciences at Stanford University, adds that case reports support complete clinical and radiological recovery when treatment is initiated promptly.
