Serum and cerebral folate levels were found to be normal in individuals diagnosed with Down Syndrome Regression Disorder.
The findings indicate the absence of folate deficiency as a causative factor in regression symptoms, supporting the current understanding of the disorder.
This observational analysis suggests that other mechanisms may be implicated in the symptoms associated with Down Syndrome Regression Disorder.
These findings highlight the need for further research to identify alternative factors contributing to regression in this population.
