What Masking Looks Like in Neurodivergent Girls and Why It Leads to Late Diagnoses

A quiet, maybe even quirky girl who follows the rules, works hard to fit in, and seems to be managing just fine is rarely who comes to mind when people think of ADHD or Autism. She's also the one most likely to go undiagnosed for years. Many neurodivergent women spent years becoming experts at appearing neurotypical. The cost of that expertise often doesn't show up until much later, sometimes not until burnout, anxiety, or depression brings them into my therapy office.

What is Masking?

Masking is the process of consciously or unconsciously hiding and containing natural neurodivergent traits to appear neurotypical. For many women, it starts early, often before they have any language for what they're doing. They learn to mirror others' expressions, rehearse conversations in advance, force eye contact that doesn't come naturally, and script their way through social situations that feel genuinely confusing, all while making it look effortless.

Why ADHD and Autism Go Unseen or Undiagnosed In Women

Part of the answer lies in how both conditions were originally studied. They were almost exclusively studied in boys, which means the diagnostic criteria were built around how ADHD and Autism tend to present in males. Girls often show up differently: less hyperactive, more internally restless; less socially withdrawn, more socially exhausted. When a girl is struggling but still functioning, still polite, still trying, she tends to get missed, or misread as anxious, sensitive, or simply not trying hard enough.

Signs of ADHD and Autism In Women

ADHD and Autism in women and girls can be easy to overlook precisely because these traits have often been absorbed into her personality, written off as 'just how she is.' She may be the woman who's always running late but has elaborate systems to compensate, who finds socializing genuinely exhausting but has learned to perform ease, or who has passionate, consuming interests that others simply call 'being intense.' The signs are there; they just tend to look like personality quirks, mood changes, or personal failings rather than neurology.

Common Myths About Neurodivergent Women

• "A diagnosis later in life means someone wasn't 'really struggling before": In reality, many of the women I work with were struggling enormously; they were simply not given support early on. They had no choice but to learn tools and skills to adapt.
• "They do not work as much as neurotypical people and can't go to college": In reality, many neurodivergent women are high achievers who have spent years developing sophisticated coping strategies just to keep up. The problem isn't capacity; it's cost. What looks like 'doing fine' from the outside often requires an exhausting amount of invisible effort, and that effort has a ceiling. By the time a woman reaches a demanding college environment or a high-stakes career, the strategies that held things together in a structured school setting may simply stop being enough.
• "Neurodivergent women lack empathy": Many neurodivergent women experience empathy very deeply. However, they may express or process their emotions differently than neurotypical expectations say they should, which can be mistakenly interpreted as coldness or indifference.
• "They cannot form meaningful relationships": Neurodivergent women deeply crave social connection and personal relationships. While sensory overload or difficulties decoding unspoken social rules can make interactions draining, they do form deep, lasting bonds when supported in a welcoming environment".

Common Accomodations that Can Help Neurodivergent Women

Accommodations aren't about lowering expectations, they're about removing unnecessary barriers so that a woman's actual capabilities can come through. In practice, this might look like flexibility around sensory needs (working in a quieter space, wearing comfortable clothing, controlling lighting), structured routines with built-in transition time, or written instructions rather than purely verbal ones. For many women, the relief of a single well-matched accommodation can be truly beneficial, not because it changes who they are, but because it stops requiring them to spend so much energy compensating.

How to Connect with a Therapist about Wanting Support for ADHD and Autism

If you're reading this and anything from this article resonated, you don't need to have it all figured out before reaching out. You can simply say, "I've been reading about ADHD and Autism in women, and I'm wondering if some of this might apply to me". That's enough. A good therapist will take it from there, and you won't need to prove anything or have the 'right' symptoms to deserve that conversation.
