Neurodiversity is a concept that recognises and embraces the variety of ways the brain can function and process information. It celebrates neurological differences, such as autism, ADHD, dyslexia and other cognitive variations, as part of human diversity rather than viewing them as disorders. Genetic factors play a critical role in shaping the brain's development and function, and understanding the genetic basis of neurodiversity can offer valuable insights into individual strengths, challenges and potential interventions. This article explores key genes that influence neurological development and cognitive functions. Understanding these genes can empower individuals and their loved ones to make informed choices about their health, optimise brain function and explore personalised strategies for support in terms of nutrition, lifestyle and supplementation, which can quite literally be life changing for some individuals.
