Cerebral folate deficiency with developmental delay, autism, and response to folinic acid
Posted: Friday. April 27, 2007
The authors describe a 6-year-old girl with developmental delay, psychomotor regression, seizures, mental retardation, and autistic features associated with low CSF levels of 5-methyltetrahydrofolate, the biologically active form of folates in CSF and blood. Folate and B12 levels were normal in peripheral tissues, suggesting cerebral folate deficiency. Results with folinic acid corrected CSF abnormalities and improved motor skills.
