Motivated by personal experience, A Wider Spectrum of Neurodivergence delves into the rapidly developing world of neurodivergence, examining how it is understood. It critiques the prevailing view of neurodivergence as a disability and the resulting power imbalance, and advocates for a shift toward recognising it as a natural variance, explaining how neurotype can be seen as a demographic, with broader implications for intersectionality.

The author explores the idea that neurodivergent traits are predominantly controlled by our genes and sets out evidence that different neurotypes have been the norm throughout human history and are likely far more prevalent than we have ever considered. Looking at language, historical context and the domination of the medical model in diagnosing neurodevelopmental "disorders", the author seeks to present alternative ways of thinking, incorporating the Neurodiversity Paradigm, the Social Model of Disability, and her own model of neurovariance which demonstrates that neurodiversity does not only exist beyond the point at which a formal diagnosis is deemed appropriate.

It is valuable reading for mental health professionals whose clients' symptoms may be better understood through the lens of neurodivergence, as well as anyone interested in the broader scope of neurodiversity.

Before moving into mental health, Sarah Royle worked as a Stage Manager, navigating the delightful madness of theatre and containing bewilderment both on and offstage. She completed her master's degree in 2009 and now brings that same calm in the chaos energy to her work as a counselling psychotherapist, supervisor, trainer, and advocate for neurodiversity inclusion.
