Why are so many adult women suddenly discovering they’re autistic, and what are the signs to look out for?

Autism in women often presents quite differently from the stereotypical autistic traits that most of us are aware of. For many women, autism remains unidentified until adulthood (if it gets identified at all), leaving them wondering why they’ve always felt somewhat out of step with the world around them. The subtle ways autism manifests in girls, women, and those assigned female at birth can make recognition challenging, but understanding these signs can be the first step toward self-knowledge and appropriate support.

Why are so many autistic women late diagnosed?

The journey to diagnosis for autistic women is often long and winding, with many reaching adulthood or even middle age before discovering their neurodivergence. This delay isn’t coincidental, though; it’s systemic.

Historically, autism research focused almost exclusively on boys. Dr. Leo Kanner and Hans Asperger, pioneers in autism research, primarily studied male subjects in the 1940s. This male-centric foundation created diagnostic criteria that still carry today. The classic autism profile—the socially awkward boy with limited eye contact and obsessive interests in trains or computer programming—has become the template against which all autistic people are measured.

For women, this has created an impossible standard. We experience autism differently, often in ways that fly under the diagnostic radar. The medical profession and society at large haven’t caught up with this reality, despite growing research showing distinct presentations in women.

Being socialized as a girl has a huge impact on how autistic women and girls present their traits. Girls face intense pressure to be agreeable, socially adept, and emotionally intuitive. To be “good girls.” These gendered expectations push many autistic girls to mask their natural tendencies from an early age, and this continues both unconsciously and consciously throughout life. Even when women do realize they’re putting on a performance, they often still don’t attribute it to autism for the reasons we’ve specified above.

But this masking comes at a tremendous cost. It leads to chronic exhaustion, identity confusion, and mental health challenges, which only confuse the picture further, because when seeking help for the resulting anxiety or depression, autistic women often find themselves slapped with misdiagnoses. Borderline personality disorder, bipolar disorder, anxiety, depression, and eating disorders are commonly assigned instead of recognizing the underlying autism.

The timing of diagnosis often correlates with life transitions that increase demands beyond an individual’s capacity to compensate. During puberty, hormonal changes can affect sensory sensitivities and emotional regulation. Leaving home for college removes familiar routines and support systems. Entering the workforce brings complex social politics. Pregnancy and motherhood introduce sensory and emotional challenges alongside decreased recovery time. And for many undiagnosed autistic women, perimenopause shines the biggest light on their neurodivergence.

It’s not that the autism has suddenly appeared at these junctures, but that many autistic women find their carefully constructed coping mechanisms collapse. The “mask of competence” becomes too heavy to maintain. The mental health crisis that often follows finally brings them into contact with knowledgeable clinicians who can recognize their autism.

Furthermore, some women only discover their autism after their children receive diagnoses. While researching their child’s traits, they recognize themselves in the descriptions, experiencing what many call an “a-ha moment” of self-recognition.

The good news is that awareness is growing. Various organizations, researchers, and individuals with lived experience are advocating for better awareness and recognition of diverse autism presentations. To help push that along, we’ve summarized some of the key differences to look out for.

What are the signs to look out for?

Whilst reading this list, it’s key to remember that no two autistic people are the same, so not all autistic women will present in the same way. Furthermore, some autistic women do present as “stereotypically” autistic, but as a result, those women will likely have been diagnosed very early on in life.

It’s also worth noting that while these traits are more commonly seen in autistic women, they can be seen in some autistic men, too.

And finally, of course, there will be neurotypical women who display some of these signs. The important thing to remember as you read this list is the severity and frequency at which the traits occur. I.e., they need to be persistent and impact your life significantly. These traits also have to have been present from a young age (i.e., they are lifelong). But of course, a child will present differently than an adult, and as we’ve mentioned, the traits might not become obviously apparent until the demands of life exceed your ability to cope.

With that in mind, here are 20 signs and traits to look out for.

1. Masking social difficulties, which comes at a serious cost.

Unlike the stereotypical male presentation, many autistic women have a strong desire to socialize and fit in. As we’ve mentioned, as a result, autistic women often become master actresses in social situations without even realizing it. This masking is particularly prevalent in situations where the child feels unsafe to be themselves, such as at school. They then come home, and their emotions and pent-up sensory overwhelm spill out uncontrollably in the form of intense meltdowns.

In adulthood, this masking may become more conscious at times (but not always), like putting on a performance in order to get through social events and fit in. However, many undiagnosed autistic women still don’t realize that autism is the reason they feel like they have to do this.

The thing about this masking business is that it’s exhausting. Many women collapse at home after socializing, completely drained from the performance. They might rehearse conversations in advance or spend so much time trying to analyse what people’s facial expressions and implied words mean that they have no energy left for anything else.

What makes masking particularly tricky is how good many autistic women become at this social mimicry. Even trained professionals can miss their autism because they’ve learned to fake it so convincingly. But the cost is real and serious. It results in identity confusion and a nagging sense of being inauthentic, all of which can contribute to isolation, anxiety, depression, and even an increased risk of suicide.

2. Struggling with unwritten social rules, but studying them intensely.

The social world is full of unspoken rules that neurotypical people absorb naturally, but for autistic women, these invisible guidelines can feel like a secret code that everyone else received the key to. Many develop an almost anthropological interest in human behavior, becoming keen people-watchers or psychology buffs in an unconscious attempt to crack this mysterious social code.

Despite these efforts, they regularly find themselves making unintentional social missteps. What makes it particularly confusing is how contextual these rules are – what’s appropriate in one setting may be completely wrong in another, with no clear explanation why. Their genuine questions about social expectations might come across as rude to neurotypical people when they’re simply trying to understand.

The confusion tends to improve in structured environments with clear expectations, but remains challenging in fluid social situations. Autistic women often describe this something like “I felt like I was playing a game where everyone knew the rules but me.”

It’s worth noting that whilst subtle social differences will be present from a young age, often social-communication challenges don’t become apparent in girls and women until puberty and beyond. Up until that point, communication is pretty straightforward regardless of gender. But come puberty, everything becomes more nuanced and unspoken in neurotypical girls’ social circles, leaving undiagnosed autistic girls floundering.

3. Experiencing social exhaustion.

For autistic women, social gatherings can feel like running a mental marathon. They’re not just chatting – they’re simultaneously processing sensory information, analyzing facial expressions, monitoring their own body language, and trying to follow conversation threads that might jump around unpredictably. And they’re often doing this without understanding why, or perhaps without even realizing that they’re doing it. They just know they feel exhausted after these events.

Their brains are essentially performing complex calculations that neurotypical people handle automatically.

Many autistic women describe needing substantial alone time after socializing, sometimes experiencing physical symptoms like headaches or digestive issues from the strain. Friends might take this personally, not understanding that it’s a neurological need rather than rejection.

4. Intense, but often conventional special interests.

While the stereotypical autistic special interest might be train schedules or computer programming, autistic women often focus intensely on interests that fly under the radar – literature, psychology, animals, art, or specific historical periods. Funnily, once they realize that they might be autistic, for many women, autism itself becomes their special interest. The key difference isn’t what they’re interested in, but how they engage with it.

When an autistic woman dives into a subject, she really dives in. She might lose track of time entirely, forget to eat, or build impressive collections of knowledge or objects related to her interests. These interests often serve as both passion and comfort zone – a predictable space in an otherwise chaotic world.

Many women describe their special interests as feeling necessary rather than optional, not just something they enjoy but something they need to engage with for their well-being. While their neurotypical friends might enjoy similar topics casually, autistic women approach them with a distinctive depth and persistence that can be quite remarkable once you know what you’re seeing.

5. Need for routines, but the distress experienced by unpredictability may be internalized.

Autistic women typically rely on routines to navigate daily life, though they might not display the obvious rigid adherence we associate with autism stereotypes. Their routines often serve as essential scaffolding that reduces mental load and provides security.

When these patterns get disrupted, even by seemingly small changes, the resulting distress can feel overwhelming. It’s not about being “inflexible” – it’s that routines serve a genuine neurological purpose, providing structure in a world that can otherwise feel chaotic and unpredictable.

Many autistic women become skilled at hiding their distress when routines change, though the internal experience remains intensely uncomfortable. They develop elaborate contingency planning to prevent unexpected changes, with backup plans for their backup plans.

What’s more, the picture gets even more complex when ADHD enters the mix. Research shows that autism and ADHD co-occur more often than not (sometimes called “AuDHD“), creating what can seem like contradictory needs. While the autistic side craves routine and predictability, the ADHD brain seeks novelty and stimulation. This internal tug-of-war can be incredibly confusing both for the woman experiencing it and for those around her.

6. Sensory sensitivities that may fluctuate.

For many autistic women, the world arrives unfiltered and overwhelming. Sounds barely noticeable to others – the hum of fluorescent lights, a ticking clock, someone chewing – might be genuinely painful or impossible to tune out. Certain fabrics against their skin can feel like sandpaper, and ordinary smells might trigger nausea or headaches.

These sensory differences aren’t preferences or being “picky” – they reflect actual neurological differences in how sensory information gets processed.

The intensity of these sensitivities often fluctuates with stress, hormones, and overall well-being. When your “window of tolerance” is lowered by these other factors, your ability to cope with sensory distress goes out the window.

Many autistic women develop complex workarounds that might appear as odd preferences to others, such as wearing the same style of clothes to avoid fabrics that cause sensory discomfort.

7. Being unfavourably labeled throughout life.

Before receiving their actual diagnosis, autistic women often collect a trail of dismissive and less-than-desirable labels throughout their lives. As children, they’re often described as “too sensitive,” “dramatic,” or “shy.” As adults, they might be called “high-maintenance,” “difficult,” “aloof,” or “rude.”

These mischaracterizations miss the mark entirely, and what’s more, the cumulative effect of these labels creates a painful internal narrative. Many autistic women internalize these descriptions, developing harsh self-criticism and increasingly desperate efforts to appear “normal.” When they finally discover they’re autistic, there’s often a profound sense of relief in understanding that they weren’t fundamentally flawed – just differently wired.

Looking back at school records, you’ll often find telling phrases – “in her own world,” “doesn’t work to potential,” or “needs to participate more” – all unrecognized signs of autism. On the flip side, they might be described as the ideal student – compliant and quiet, if a little shy. The burden of carrying these mischaracterizations for years contributes significantly to the anxiety and depression many autistic women experience.

8. Feeling consistently misunderstood.

Communication breakdowns can be a regular feature of daily life for autistic women. Despite carefully choosing their words, they may frequently find themselves misinterpreted, while simultaneously struggling to decipher others’ indirect communication styles. This creates a persistent sense of speaking different languages.

The concept that autism researcher Dr. Damian Milton calls the “double empathy problem” beautifully explains this phenomenon – it’s not simply that autistic people struggle to understand neurotypical communication, but that both groups have trouble understanding each other’s different communication styles.

In response to these ongoing misunderstandings, many autistic women become incredibly precise in their language, providing extensive detail to prevent confusion. Ironically, this thoroughness can further complicate matters when others find it overly pedantic. The frustration of repeatedly failing to connect despite their best efforts can be profoundly isolating.

9. Discomfort with eye contact, but not necessarily avoiding it.

Many autistic women find eye contact intensely uncomfortable or distracting, though they’ve often learned to fake it convincingly because of society’s obsession with a lack of eye contact signaling rudeness or shady behavior. The sensation they experience ranges from feeling uncomfortably exposed to experiencing actual physical discomfort or information overload.

To manage social expectations, they develop creative workarounds such as looking at the bridge of the nose, maintaining brief periodic eye contact, or positioning themselves at angles that make sustained eye contact less necessary. The mental effort required to maintain “appropriate” eye contact while simultaneously processing conversation content creates a real cognitive burden.

Autistic women frequently report that they can either make eye contact OR follow what someone is saying, but doing both simultaneously feels impossible. This creates a painful choice between appearing engaged (through eye contact) or actually being engaged (by focusing on the conversation content). The social pressure to maintain eye contact can significantly contribute to their exhaustion in social settings.

10. Difficulties understanding implied communication or intention, that can have serious consequences.

“Just figure it out” instructions can send an autistic woman into a tailspin of anxiety. They typically thrive on clear, detailed directions rather than vague guidelines with implied expectations. When faced with ambiguous instructions, they often experience genuine confusion and distress. Their follow-up questions aren’t meant to be difficult or challenging – they’re attempting to gather the specific information their brains need to proceed confidently.

This difficulty with implicit communication extends far beyond workplace frustrations, though, and it has serious implications. Autistic women often struggle to detect subtle warning signs in relationships and social situations that others pick up intuitively. This inability to “read between the lines” can, unfortunately, make them more vulnerable to manipulation and abuse.

Research shows that autistic women experience significantly higher rates of various forms of abuse throughout their lives. Their tendency to take others at their word, combined with difficulty recognizing malicious intent disguised as friendliness, creates particular vulnerability. An autistic woman might miss the red flags that would alert others to a controlling partner or exploitative friendship.

11. A strong sense of justice.

Women who are autistic often possess an unwavering commitment to fairness that can appear rigid to others. Their moral compass isn’t just strong – it’s often central to their identity.

It stems from a genuine conviction about right and wrong that feels non-negotiable. When they notice inconsistencies in rules or unfair treatment, many feel compelled to speak up, even when it’s socially inconvenient or risky.

Their advocacy typically extends beyond self-interest to defending others who experience mistreatment. This strong justice orientation can make autistic women excellent advocates and whistleblowers, though it may create tension in environments where social harmony is valued above fairness. The black-and-white thinking often associated with autism contributes to this moral clarity, making ethical compromises genuinely distressing rather than merely uncomfortable.

12. Executive functioning challenges.

The idea of the autistic spiky profile explains why some brilliant autistic woman can solve complex problems but struggle to keep their house organized or cook a basic meal. Executive functioning challenges are common in autistic women, affecting their ability to plan, organize, initiate tasks, and switch between activities. These difficulties often look different from the stereotypical “absent-minded professor” image we associate with autistic men.

Many develop elaborate compensatory systems – detailed planners, reminder apps, and strict routines – that can effectively mask these challenges. The disconnect between their often high intelligence and these everyday struggles creates particular frustration.

What’s especially interesting is how their executive function varies dramatically depending on interest level. The same woman who can organize an entire research project might find loading the dishwasher overwhelming. This inconsistency often leads to misunderstanding, with others perceiving them as lazy or deliberately choosing not to complete certain tasks, when they’re actually experiencing genuine cognitive barriers.

13. Gender non-conformity.

Many autistic women approach gender as a puzzling social construct rather than an innate identity. They often question gendered assumptions that others take for granted, making choices based on comfort and practicality rather than social expectations. This might show up as clothing choices prioritizing comfort over fashion, disinterest in makeup, or confusion about the unwritten rules of “feminine” behavior. It’s important to remember, though, that no two autistic people are the same, and indeed, some autistic women go on to have special interests in traditionally feminine topics like fashion and make up.

Research reveals significantly higher rates of gender diversity among autistic individuals. This may reflect reduced influence of social conditioning on identity development – autistic people often feel less pressure to conform to expectations that don’t make internal sense to them.

Many describe feeling “gender-blind” in their interests and self-expression, pursuing activities based on genuine preference rather than gender appropriateness. This gender non-conformity frequently begins in childhood with rejection of traditionally “girly” toys or activities. They simply like what they like and don’t understand the ridiculousness of labelling a toy as being for girls or boys.

14. Differences in emotional expression.

The harmful myth that autism means “lacking empathy” persists despite evidence showing many autistic people, women in particular, experience heightened empathy that becomes overwhelming. The issue isn’t the absence of empathy but a difference that neurotypical people can’t comprehend because the autistic woman’s face might not express emotions in ways that align with social expectations. Their facial expressions might not match their internal emotional states, or they might become overwhelmed and shut down during emotional conversations.

In fact, many autistic women describe absorbing others’ feelings like emotional sponges without the typical filtering mechanisms. This can lead to empathic overload – feeling others’ pain so intensely that they become overwhelmed.

Complicating matters further, alexithymia, that is, the difficulty identifying and naming their own emotions, is common in autism. Autistic women might feel intense emotional states without being able to categorize them as specific feelings like “anxious” or “disappointed.” Furthermore, interoception – the sense that helps us feel internal bodily signals like hunger, thirst, or emotional states – often works differently in autism. Many autistic women report delayed recognition of physical and emotional states, sometimes only realizing they’re hungry, exhausted, or upset after reaching an extreme point.

Between this heightened empathy, alexithymia, and interoceptive differences, many autistic women find themselves overwhelmed by emotions that they can’t always name, express, or regulate in neurotypical ways.

15. Intense emotional reactions (known as “meltdowns”).

When it comes to managing emotions, many autistic women experience what feels like a faulty volume control. Their emotional responses can quickly escalate from manageable to overwhelming due to a variety of autism-related challenges, and it’s not about being “dramatic” or “overreacting.”

Sensory overload frequently triggers emotional dysregulation. The cumulative effect of fluorescent lights, background conversations, uncomfortable clothing, and unexpected touches can push an already-taxed nervous system into fight-or-flight mode. What others perceive as an emotional reaction to a minor problem might actually be the final straw after hours of sensory bombardment.

Exhaustion from masking plays a significant role, too. After days of carefully monitoring facial expressions, body language, and conversation flow, emotional regulation resources become depleted. The same woman who handles workplace stress capably on Monday might find herself unable to manage a minor disappointment by Friday due to this cumulative drain.

Unexpected changes to routines or plans create another common trigger. What seems like a simple schedule adjustment to others can represent a genuine threat to the security and predictability that autistic women rely on for functioning.

In some cases, dysregulation can escalate to what’s known as an autistic meltdown – an intense response to overwhelming situations that may involve crying, shouting, or stimming. Unlike tantrums, meltdowns aren’t manipulative or attention-seeking but represent genuine neurological overwhelm. Conversely, this dysregulation can involve a shutdown instead, when an autistic person may lose the ability to speak and become completely withdrawn.

This can be particularly hard for undiagnosed autistic women to handle. They constantly feel like they are failing at life, unable to cope with things that everyone else can manage. What’s more, the shame associated with meltdowns, especially when they occur publicly, can be hard to bear. Understanding these reactions as neurological differences rather than character flaws can help autistic women develop appropriate regulation strategies instead of self-criticism, which is why identifying autism is so important.

16. Experiencing periods of burnout after masking.

Autistic burnout is real and devastating. After prolonged periods of masking, many women experience a profound collapse of functioning when the exhaustion of maintaining a neurotypical appearance becomes unsustainable.

This state goes beyond ordinary fatigue to a breakdown of coping mechanisms that can resemble depression but prove resistant to typical treatments. Symptoms often include increased sensory sensitivities, executive function difficulties, emotional dysregulation, and intensified autistic traits that were previously well-concealed.

Each burnout episode typically leaves lasting effects, with diminished capacity for masking afterward. Recovery requires significant reduction in masking efforts and increased authenticity, often necessitating life changes that prioritize neurological needs over social conformity.

17. Preference for direct communication.

Autistic women generally prefer straightforward, explicit communication over the hints, implications, and social subtleties that characterize neurotypical conversation. Their communication style emphasizes clarity and literal meaning rather than social positioning or face-saving indirectness.

Many express confusion when described as “brutally honest” or “too direct” when they believed they were simply being clear and efficient. Their questions often aim to gather precise information rather than initiate social exchanges, creating misunderstandings when others interpret information-seeking as rudeness.

Research in this area, including recent work by Dr. Catherine Crompton, suggests that autistic people communicate effectively with each other while experiencing challenges in mixed neurological conversations. This highlights that in speaking with autistic individuals, communication difficulties often arise from a mismatch between neurotypes rather than from inherent deficits.

What’s more, autistic women often find neurotypical communication equally as frustrating. They often appreciate directness and would rather hear the unvarnished truth than comforting but confusing mixed messages.

18. Experiencing chronic health conditions.

Many autistic women also experience an array of widespread and persistent physical symptoms such as headaches, migraine, visual problems, gut issues, and chronic pain, to name a few. The connection between autism and various physical chronic health conditions isn’t coincidental – emerging research suggests genuine biological links that we’re only beginning to understand. Autistic people’s nervous systems are often in a permanent state of threat, which manifests as chronic pain and heightened sensitivity to other physical sensations.

In particular, Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorder (HSD), a group of connective tissue disorders causing hypermobility, are significantly more common in autistic people, particularly women, than in the general population. As connective tissue is everywhere in the body, it comes with a host of symptoms that can appear strange and unrelated. As a result, medical professionals can’t connect the dots, and many women report being dismissed by medical professionals, with their symptoms attributed to anxiety or stress before eventually receiving a proper diagnosis (if at all).

Over their lifetime, the wide variety of ailments autistic women experience leads them to be viewed as dramatic, often being dismissed as hypochondriacs or overreacting. It’s often only when the issues are connected do they start to receive the support and validation understanding they deserve.

19. A lifelong feeling of difference.

“I always felt like I was from another planet.” This sentiment echoes through countless conversations with autistic women. Many describe a persistent sense of being fundamentally different from those around them, often dating back to their earliest memories.

This feeling goes beyond normal individuality to a profound sense of operating on a different wavelength than peers. Many articulate this experience as feeling like “an alien” studying humans from the outside, never quite grasping the unspoken rules that others seem born understanding.

In her wonderful book, the influential autistic writer, speaker, and autism diagnostician, Sarah Hendrickx, documents how this sense of difference creates both isolation and a searching quality. Many women spend years seeking explanations through various psychological, spiritual, or self-help frameworks before discovering autism. The relief of finally naming this difference often brings profound emotional release – finally understanding you’re not broken, just different in a specific and recognizable way.

20. Difficulty with transitions (as well as difficulties increasing during major life transitions).

Life changes that others take in stride can feel like earthquakes to autistic women. They often struggle significantly with transitions between activities, environments, or life stages. This difficulty goes beyond a simple preference for routine to a genuine cognitive challenge in shifting attention and adapting to new circumstances.

Major life transitions like beginning college, changing jobs, or becoming a parent can trigger periods of increased autistic traits and distress as coping mechanisms become overwhelmed.

This is particularly pronounced during hormonal transitions throughout a woman’s life. Many women report increased sensory sensitivities, executive function challenges, and emotional dysregulation during puberty, pregnancy, postpartum periods, and perimenopause, and research backs this up. These hormonal shifts appear to reduce available resources for masking and coping, making previously manageable situations suddenly overwhelming.

This pattern often contributes to diagnosis after major life transitions when compensatory strategies become insufficient. I have lost track of the number of late-diagnosed autistic women who have reported they’ve “held it together” for decades until menopause suddenly made their autism impossible to ignore or mask.

Final thoughts…

If several of these signs resonate with your experience or someone you know, it might be worth exploring autism further.

Whether you pursue formal diagnosis or simply use this information for self-understanding, recognizing these patterns can provide context for lifelong experiences and help develop accommodations that work with your natural neurological style rather than against it.

The growing recognition of diverse autism presentations is gradually making the path to understanding easier for women who’ve spent too long wondering why they feel different from those around them. You’re not alone in this journey – there’s a growing community of autistic women sharing their experiences and supporting each other in embracing their authentic selves.
