An area warranting future research
The growth of pharmacogenomics represents an important opportunity to bridge the gap between our understanding of psychiatric illnesses and new ways to treat them. Using L-methylfolate to treat ADHD might help bridge this gap. For this to occur, psychiatrists need to use evidence-based pharmacogenetic research to inform their decision-making. The differing results in studies evaluating the use of L-methylfolate in adult and pediatric patients pose interesting questions that will require more robust research to answer. Clinicians should be cautious in the use of L-methylfolate and recognize the importance of evaluating every patient with ADHD for MTHFR deficiency. This could help personalize care in ways that may improve the quality of life for patients and their families.
