Writing Neurodivergent Characters That Ring True

Neurodivergence refers to neurological development that diverges from what is statistically typical, including autism, ADHD, dyslexia, dyscalculia, dyspraxia, Tourette syndrome, and others. The term was coined by sociologist Judy Singer in the late 1990s and has become the standard framing in both activist and clinical contexts. Each condition has a different profile: ADHD primarily involves attention regulation and executive function; autism involves social processing, sensory integration, and pattern thinking; dyslexia involves reading and language processing. These conditions frequently co-occur. When writing neurodivergent characters, the first step is understanding exactly what cognitive difference you are depicting and how it actually shapes daily experience, rather than defaulting to stereotypes built on dramatic presentations or outdated clinical descriptions.

Masking is the practice of concealing neurodivergent traits to appear neurotypical in social situations. Most neurodivergent people, particularly autistic people and those with ADHD, mask to some degree, often from early childhood. Masking is cognitively exhausting and long-term masking is associated with anxiety, depression, and burnout. Fiction that depicts neurodivergent characters as simply awkward or unaware often misses the reality that many neurodivergent people are acutely aware of social expectations and work very hard to meet them, at significant personal cost. The character who appears to function normally in public but crashes privately is a more accurate portrayal than the character who is oblivious to social dynamics. The costs of masking, and the experience of finally not having to mask, are rich territory for fiction.

Sensory processing differences are central to many neurodivergent experiences, particularly autism. Autistic sensory profiles can involve hypersensitivity (sounds, lights, textures, smells that are overwhelming to others) or hyposensitivity (requiring intense input to register sensation) or both in different modalities. This is not a minor character detail. For many autistic people, the sensory environment determines whether a situation is manageable or not. Writing this into your prose is both an accuracy issue and a craft opportunity. Sensory-rich prose from an autistic point of view creates genuine interiority and strangeness. The grocery store fluorescent lights that make everything feel like drowning. The scratch of a fabric tag that cannot be ignored no matter what is happening. Used well, sensory detail makes neurodivergent POV viscerally understandable to neurotypical readers.

ADHD in fiction is frequently used for comedy: the distracted, impulsive, charming disaster who stumbles into success through luck and endearing failure. This portrayal is not inaccurate in every detail, but it reduces ADHD to its most visible and entertaining surface features while missing the interior experience. ADHD involves a dysregulated attention system, not absent attention: ADHD brains can hyperfocus intensely on things that engage them, while finding it genuinely difficult to direct attention toward less stimulating tasks. The emotional dysregulation component of ADHD, which can involve intense emotional responses and difficulty recovering from rejection or criticism, is rarely depicted in fiction at all. ADHD characters who are written with interior complexity, including the shame, the compensation strategies, and the specific texture of time blindness, are far more interesting than the lovable mess.

The Sherlock Holmes autistic genius trope, even when Holmes is not explicitly diagnosed, has become the dominant autistic character archetype in popular fiction. The template: high intelligence, low social awareness, emotional coolness, and often a streak of moral indifference. This trope is limiting for several reasons. It conflates autism with high intelligence (autism occurs across the full range of cognitive ability). It depicts emotional coolness as characteristic (autistic people often have intense emotional lives, though they may process and express emotion differently). And it treats social difficulty as an amusing character quirk rather than something that has real costs and requires real adaptation. Autistic characters can be funny, warm, romantically engaged, morally complicated, and wrong. They do not need to compensate for their neurology with genius.

Neurodivergent ARC readers are your most valuable early audience for neurodivergent fiction. They will catch the detail that rings false, the coping strategy that does not work the way you have depicted it, the sensory description that misses the actual experience. Their early reviews also signal to other neurodivergent readers that the book has been vetted by the community. Finding neurodivergent ARC readers requires going to spaces where they gather: ADHD and autism communities on social media, neurodivergent book clubs, and neurodivergent-focused bookstagram and BookTok accounts. iWrity allows you to specify neurodivergent identity in reader matching, so your ARC request reaches people who self-identify with the experience you are depicting, rather than general readers who may engage enthusiastically but lack the context to evaluate accuracy.
