Contributions to Orthomolecular Medicine
In 2014, Integrative Medicine for Children’s Mental Health was launched. This continuing medical education program was developed by Dr. Gannage, in collaboration with the Canadian Society for Orthomolecular Medicine. The program was accredited by the College of Family Physicians of Canada, and presented throughout 2014, 2015 and 2016, in Toronto, Vancouver, and Calgary. Integrative Medicine for Children’s Mental Health provides an evidence-based approach to addressing ASD, ADHD and other mental health conditions with an emphasis on nutritional and environmental factors. It supports an understanding of the gut-microbiome-brain axis, oxidative stress, immune dysregulation and the role of environmental toxicants in the development and diagnosis of mental health conditions in children.
Dr. Gannage has also presented seminars for the Orthomolecular Health Public Education Series, and authored articles published in the Journal of Orthomolecular Medicine.
