Signs Your Daughter Might Have ADHD or Autism: What Parents in NJ Need to Know
You know something is going on. You have known for a while, actually. Maybe your daughter is brilliant and perceptive but falls apart over small changes in routine. Maybe she comes home from school every day completely depleted, like she has been holding herself together with everything she has. Maybe she has always seemed to feel things more intensely than other kids, or has struggled to make and keep friends in ways that are hard to explain.
You have mentioned it to her pediatrician. Maybe you were told she is just sensitive, or anxious, or that girls mature differently. Maybe she even had an evaluation and nothing was found. But the feeling that something is being missed has never gone away.
You are probably right.
ADHD and Autism in girls are missed at extraordinary rates, not because the conditions are rarer in girls, but because they present differently, and because the people doing the evaluating are often not trained to recognize how. This post is for parents who are wondering, who are watching, and who are ready to get some real answers.
Why I Wanted to Write This
I am a neurodivergent clinician, and I am a late-diagnosed autistic and ADHD woman. For most of my life, I navigated a world that was not designed for how my brain works, and I did it without knowing why so many things that seemed effortless for others required so much more from me. I learned, as so many girls do, to watch other people carefully and mirror what I saw so I could fit in.
When I finally understood what was actually going on, I felt two things at once: an enormous sense of relief, and a grief for all the years I spent not knowing. That experience is a significant part of why I do this work and why I have specialized in evaluating girls and women who have spent too long without answers.
If your daughter is one of those girls, I want you to know that what you are seeing is real. And there is a path to understanding it.
Why Girls with ADHD and Autism Are So Often Missed
The diagnostic criteria for both ADHD and Autism were developed based on research conducted almost entirely on boys. The presentations that were studied, hyperactivity, impulsivity, overt social difficulties, and obvious repetitive behaviors, reflect how these conditions more commonly appear in males. Girls were largely left out of the research, and the field is still catching up.
The result is that entire generations of girls went undiagnosed. Research suggests that girls with ADHD are diagnosed on average several years later than boys, and autistic girls are significantly more likely to receive an initial misdiagnosis of anxiety, depression, or a personality disorder before anyone considers Autism. These were the girls who were described as sensitive, dramatic, shy, or anxious. They were praised for being well-behaved even when they were struggling enormously on the inside. And they learned, often without realizing it, to hide.
This is called masking, and it is one of the most significant reasons girls are missed for so long.
What Is Masking and Why Does It Matter?
Masking is the process of suppressing or hiding neurodivergent traits in order to appear neurotypical. It can be conscious or completely automatic, something a child develops over years of watching what gets rewarded and what gets criticized.
Girls are particularly prone to masking for several reasons. Social pressures on girls to be agreeable, cooperative, and socially adept start early and run deep. A girl who has learned that being different is not safe will work incredibly hard to hide it.
A masked girl might look like this: she does well enough academically to avoid attention, holds herself together at school, and then completely falls apart the moment she gets home. She may have one or two close friends but find larger social situations exhausting. She may seem anxious or emotional to those around her, while the neurodevelopmental difference underneath goes unrecognized.
The cost of masking is significant. Chronic masking leads to exhaustion, anxiety, depression, and over time, a profound disconnection from who she actually is. Many girls who are diagnosed as teens or adults describe having spent years feeling like they were performing a version of themselves rather than actually living.
Signs of ADHD in Girls
ADHD in girls frequently looks nothing like the hyperactive, impulsive boy that most people picture. Girls with ADHD are more likely to present with the inattentive type, which is quieter, less disruptive, and far easier to overlook. This is true for young girls and it is equally true for teenage girls, who are often dismissed as moody, scattered, or overwhelmed by the demands of adolescence when ADHD is actually driving what parents and teachers are seeing.
What You Might Be Seeing at Home
She starts tasks with good intentions but rarely finishes them
She loses things constantly, backpacks, homework, permission slips, even things she just had in her hands
She is easily overwhelmed by tasks with multiple steps
She has big emotional reactions that seem disproportionate and are hard for her to recover from
She hyperfocuses intensely on things she loves while being completely unable to engage with things she does not
She seems to live in her own world, daydreaming, distracted, somewhere else
She is exhausted at the end of every school day even though nothing obvious happened
What You Might Be Hearing from Teachers
She is bright but does not apply herself
She seems distracted and does not follow through
She is very sensitive
She could do better if she just tried harder
These observations are often well-meaning but miss the point entirely. The struggle is real, and it is not about effort.
Signs of Autism in Girls
Autistic girls are among the most frequently misidentified and misunderstood children in clinical settings. Their presentations are often subtle, socially sophisticated, and very different from what most people, including many clinicians, expect Autism to look like. In teenage girls specifically, Autism can become even harder to detect as masking strategies grow more refined and the social demands of adolescence intensify the pressure to fit in.
Social Differences That May Be Hard to See
She has learned to mimic social behavior by carefully watching others, but social interaction still costs her enormously
She may have one or two very close friendships but struggles significantly with groups
She finds unwritten social rules confusing, even if she has memorized the written ones
She comes home from school emotionally depleted from the effort of navigating social situations all day
She may be described as mature for her age because she prefers adult company or one-on-one conversations
Sensory and Emotional Signs
Strong sensory sensitivities, to sounds, textures, lights, smells, or crowds
Clothing that bothers her, tags, seams, certain fabrics, becomes a daily battle
She becomes dysregulated in busy or unpredictable environments
She has intense, deep interests that she can talk about endlessly and with great detail
She needs significant transition time and becomes very distressed when plans change unexpectedly
She seems to feel things much more deeply than other kids her age
What Can Be Mistaken for Something Else
Many of the signs of Autism in girls get labeled as anxiety, OCD, giftedness, shyness, or simply being high-strung. Without an evaluator who is specifically trained in the female presentation of Autism, these signs are easy to miss or misattribute.
What If She Has Both ADHD and Autism?
It is increasingly recognized that ADHD and Autism co-occur in many children, a combination sometimes referred to as AuDHD. In girls, this combination can be particularly complex because the traits of each condition can interact in ways that make both harder to identify.
A girl with both ADHD and Autism may appear to cancel out the classic signs of each. Her Autism-driven need for routine may look like it compensates for her ADHD impulsivity. Her ADHD-driven social seeking may look like it compensates for her Autism-related social differences. The result is that she does not look like a textbook case of either, and she may slip through evaluations without a clear answer.
A comprehensive evaluation that looks at both ADHD and Autism together, rather than one in isolation, is especially important for girls who show signs of both.
What Happens When Girls Go Undiagnosed
The consequences of missed or late diagnosis in girls are well documented and significant. Without understanding what is actually going on, girls develop explanations for their struggles that are almost always self-blaming. They conclude that they are not smart enough, not trying hard enough, too emotional, too weird, or simply broken in some way they cannot name.
By adolescence, many undiagnosed girls are also dealing with anxiety, depression, and sometimes eating disorders or self-harm, conditions that developed downstream from years of being unsupported and misunderstood. If reading this brings up guilt or grief as a parent, that is a completely understandable response. You were likely doing everything you knew to do with the information you had. The system failed your daughter long before you found this page.
Your daughter may have learned to mask so effectively that even the people closest to her do not see the degree to which she is struggling.
An accurate evaluation does not erase those years. But it can change the story your daughter tells herself about who she is and why things have been so hard. That shift alone can be profound.

Frequently Asked Questions About ADHD and Autism in Girls
-
A: Girls are frequently missed because the diagnostic criteria for both ADHD and Autism were historically developed based on research conducted almost exclusively on boys. Girls tend to internalize their struggles, mask their differences, and develop social compensation strategies that make their symptoms less visible to teachers, pediatricians, and even parents. As a result, they are often diagnosed with anxiety or depression first, sometimes years before anyone considers ADHD or Autism.
-
A: ADHD in girls often looks different from the hyperactive, impulsive presentation more commonly associated with boys. Girls with ADHD are more likely to present with inattentive symptoms: daydreaming, difficulty staying organized, forgetting things, struggling to complete tasks, and feeling emotionally overwhelmed. They may appear quiet, dreamy, or anxious rather than disruptive, which is why they are so often overlooked.
-
A: Autistic girls often present very differently from the stereotypical male presentation of Autism. They tend to develop strong social mimicry skills, carefully watching and copying others in order to fit in. They may have intense interests that appear more socially acceptable, such as animals, books, or specific people, which can cause their depth of focus to go unnoticed. Sensory sensitivities, emotional dysregulation, and a deep need for routine are often present but mistaken for personality traits rather than neurological differences.
-
A: Masking refers to the conscious or unconscious suppression of neurodivergent traits in order to appear neurotypical. Girls are particularly prone to masking because of social pressures to be agreeable, quiet, and socially skilled. A girl who is masking may seem perfectly fine at school but fall apart completely at home, because the effort of holding herself together all day leaves nothing in reserve. Over time, chronic masking leads to exhaustion, anxiety, depression, and a profound loss of sense of self.
-
A: Yes, absolutely. Previous evaluations that returned negative results are often conducted without specialized training in the female presentation of ADHD and Autism. If your daughter's struggles have continued despite a previous evaluation, or if the results never quite seemed to capture what you were seeing at home, seeking a second opinion from a clinician with specialized expertise in girls and masking is completely valid and increasingly common.
-
A: At True Reflections Mental Health Services in Middlesex, NJ, Autism evaluations are available starting at age 2.5 and ADHD evaluations begin at age 4, for children through age 17. Early identification is especially important for girls, whose masking strategies become more sophisticated with age, making later evaluations more complex.
