Neurodivergence is an umbrella term that is used to describe differences in neurocognitive processing, ways of being and experiencing the world. This guide focuses on two aspects of neurodivergence, (non-learning-disabled) Autism and ADHD. Recent estimations suggest that approximately 15% of the global population are Neurodivergent, but it is also recognised that neurodivergence is vastly under-diagnosed1213. Reasons why people may not have a formal diagnosis include personal choice (not everyone feels that they need a label or a medical diagnosis), lack of access to assessment, gender-norms and inequalities14. (Neurodivergent women are often misdiagnosed with anxiety or depression for instance) or because people are unaware that they are Neurodivergent. The medical data on neurodivergence is therefore limited and unreliable. Research into neurodivergence, particularly in relation to intimate relationships and domestic abuse is also extremely scarce; a gap in understanding that Dr Renehan and others are working to address.
