It's understandable that women who spend years struggling with various issus may ask whether ADHD or autism is being missed because they are women. Research supports part of that concern, and historically women have had various medical issues "less actively" investigated. However, the picture is more complicated than a simple claim that every woman is underdiagnosed.
A 2024 review published in The Lancet Psychiatry found that female patients were less likely to receive an ADHD diagnosis during childhood, are often diagnosed later, and are less likely to receive medication even after diagnosis. The authors discuss several possible explanations including differences in how symptoms appear, compensatory behaviour, diagnostic practices, and the possibility that existing approaches do not recognise every presentation equally well.

Autism presents a similar problem. A review by researchers at University College London explains that some girls and women may be missed when they camouflage difficulties by copying social behaviour, rehearsing conversations, or hiding distress. Someone may appear sociable or capable while using considerable effort to manage situations that others find routine. The review, Improving Diagnostic Procedures in Autism for Girls and Women, made an important qualification: existing diagnostic definitions can be used across genders, but assessments need to consider a wider range of behaviours and information.
"Women, like men, should try to do the impossible. And when they fail, their failure should be but a challenge to others." - Amelia Earhart
This means lower diagnosis rates do not automatically prove every clinician is biased or that women are being deliberately overlooked. The issue is more about what professionals expect to see, how symptoms are interpreted, and whether the person's history is explored carefully. A girl whose difficulties appear mainly as inattentiveness, anxiety, or exhaustion may attract less attention than a child displaying disruptive hyperactivity. So if you have a hundred boys with hyperactivity and a hundred girls with anxiety - the idea all 200 have ADHD simply isn't going to be the first guess. Similarly, an autistic girl may be considered shy, sensitive, or socially awkward rather than assessed for a neurodevelopmental condition. This has more to do with societal expectations than any wilful ignorance by a doctor.
There are differences between ADHD and autism which are not always made clear when people discuss under or over-diagnosis problems. So the same explanations should not be applied to both anyway. ADHD can involve difficulties with attention, organisation, impulsivity and managing tasks. Autism can involve differences in social communication, sensory processing, routines and restricted interests. Both conditions can be expressed in varied ways, and the presence of one does not establish the other.
One thing which can be changed immediately though is how women are treated after finally getting the diagnosis. A late diagnosis can help explain earlier experiences, but it does not then guarantee immediate support. Women may still face lengthy assessment queues, uncertainty about eligibility, and limited post-diagnostic services.
If you suspect ADHD or autism, keep examples of the problems you experience across different settings. Explain how they affect employment, study, relationships, sensory comfort, organisation or recovery after social activity. Childhood information, school reports and observations from people who know you may also help an assessment, where available. Because of the challenges ADHD and Autism bring, it is not a good idea to rely on your memory about what you're struggling with in daily life. Make (conservative and concise) notes.
So yes, evidence indicates that gaps exist in the diagnosies of these conditions in women, especially in childhood. But individual assessment still needs to consider the person rather than relying on gender stereotypes or doing what people generally do in these circumstances and snap backwards into the the opposite problem - i.e. overdiagnosing and piling every conceivable treatment onto every child instead.
