Maybe you’ve been watching videos about ADHD or autism and keep thinking, Wait, I do that.
Maybe someone in your family was diagnosed and suddenly you started recognizing similarities in yourself. Maybe you’ve always known that certain things seem harder for you than they appear to be for other people, but you’ve never really understood why.
Or maybe a lot of seemingly unrelated things are suddenly starting to look a little more related.
You don’t have to know what that means yet.
Curiosity is enough reason to start learning about yourself.
The goal right now doesn’t have to be deciding whether you have ADHD or autism. Start smaller.
Learn. Pay attention. Write things down. See what patterns emerge.
Why Does This Keep Sounding Like Me?
One of the strange things about discovering ADHD or autism later in life is that the information can feel new while the experiences themselves feel incredibly familiar.
You might learn about executive dysfunction and remember all the times you’ve sat there wanting to do something but couldn’t seem to make yourself start.
You might learn about sensory sensitivity and think about how you’ve always avoided certain sounds, textures, lights, foods, or environments.
You might hear someone describe scripting conversations and suddenly remember how often you’ve rehearsed what you were going to say before making a phone call.
One experience doesn’t tell you very much.
But then another thing sounds familiar.
And another.
Eventually, you may find yourself asking a different question:
What if some of the things I’ve always thought were unrelated are actually connected?
That’s a question worth exploring.
Research into people diagnosed with ADHD in adulthood shows that this kind of looking backward is common. A 2026 systematic review of 21 studies found that receiving an adult ADHD diagnosis often triggered substantial reflection on a person’s life history and identity. An earlier qualitative meta-synthesis described themes including an “unnecessary struggle,” diagnosis as both revelation and burden, and the feeling that a more functional life was finally possible.1 2
You don’t need to wait for a diagnosis to start asking questions about your own history.
But Wouldn’t Someone Have Noticed?
This can be one of the biggest reasons to dismiss your own curiosity.
If I really had ADHD, wouldn’t my teachers have noticed?
Wouldn’t my parents have known?
Wouldn’t someone have noticed I was autistic?
Not necessarily.
Our understanding of both ADHD and autism has changed considerably, and what other people see from the outside isn’t necessarily the same as what you’re experiencing internally.
Research on adult ADHD has identified stereotypes about ADHD being a condition of hyperactive boys, limited professional awareness of adult ADHD, and variation in how ADHD presents across the lifespan as contributors to underrecognition.1
Autism has similar problems.
Some autistic people learn to consciously or unconsciously camouflage parts of themselves in social situations. That can include monitoring behavior, copying other people, preparing conversations, suppressing natural responses, or developing strategies that help them navigate situations that don’t come naturally.
In qualitative research involving 277 autistic adults, participants described camouflaging as something that could help them function socially while also contributing to exhaustion, isolation, unrealistic expectations from others, and delayed recognition of autism.3 Other research has found that gender stereotypes and assessment tools that don’t adequately capture some presentations may also contribute to delayed autism identification.4
So instead of asking:
“Why didn’t anyone notice?”
it may be more useful to start asking:
“What have I actually been experiencing?”
Start With Curiosity
You don’t need to turn yourself into a research project overnight.
When you encounter an ADHD or autistic trait that sounds familiar, just pause for a moment.
Ask:
Where does this show up in my life?
Not where you could make it fit.
Where does it actually happen?
Maybe someone describes losing track of a task halfway through doing it.
Does that happen to you?
What does it actually look like?
Maybe someone talks about becoming overwhelmed in a loud restaurant.
What happens when you’re in one?
Maybe someone describes needing to prepare conversations beforehand.
Do you do that? When? With whom? What happens if you can’t prepare?
That’s where this starts becoming useful.
You’re moving away from an abstract list of traits and toward understanding your own experiences.
Take Some Free Screening Tests
Screening tools can also give you a structured place to begin.
Embrace Autism provides several free ADHD and autism questionnaires online, along with explanations of what they measure and how their scoring works.8
For ADHD, one useful starting point is the Adult ADHD Self-Report Scale (ASRS). The six-question WHO ASRS screener has been studied as a brief tool for identifying adults who may warrant further ADHD evaluation, and an updated DSM-5 version also demonstrated strong ability to distinguish ADHD cases in validation research.5 6
For autism, some useful starting points available through Embrace Autism include:
- AQ — Autism Spectrum Quotient
- RAADS-R — Ritvo Autism Asperger Diagnostic Scale-Revised
- CAT-Q — Camouflaging Autistic Traits Questionnaire
Embrace Autism’s autism tests and scoring guide 8
The CAT-Q is particularly interesting if you’ve started wondering whether you’ve spent years consciously or unconsciously adapting yourself socially. It measures three areas related to social camouflaging: compensation, masking, and assimilation.7
But there’s something important to understand about all of these tests:
Don’t reduce the experience to your score.
A screening questionnaire isn’t the whole answer.
For example, Embrace Autism’s guidance for the RAADS-R cautions that a score should be interpreted as one part of a larger picture and not treated as a diagnosis.9
Instead, pay attention to the questions themselves.
Which question made you immediately think of something from your life?
Which one made you stop?
Which one reminded you of childhood?
Which one made you think:
“Wait. I do that all the time.”
Write that down.
That’s where the next part becomes important.
Start a Trait Journal
If there’s one practical thing I would recommend doing while exploring ADHD or autism, it’s this:
Start documenting your experiences.
You don’t need a complicated spreadsheet or special journal.
When something happens that seems relevant, write down three things:
1. What were you doing?
Give yourself the context.
Where were you?
What were you trying to accomplish?
Who was there?
What was happening immediately beforehand?
2. What happened?
Describe the experience itself.
Try not to worry about what it’s called yet.
Just describe it.
3. How did it impact you?
This part is important.
Did you abandon the task?
Did you become overwhelmed?
Did you need an hour to recover?
Did you forget something important?
Did it cause a problem at work?
Did you avoid doing something afterward?
Did you have to create some unusual workaround to get through it?
You’re creating a record of your actual experience.
For example:
What I was doing:
Trying to clean the kitchen before someone came over.
What happened:
I started unloading the dishwasher, noticed something in the wrong cabinet, went to move it, found something else that needed to be put away, left the kitchen, and twenty minutes later realized I had never finished unloading the dishwasher.
How it impacted me:
The kitchen wasn’t finished, I became frustrated with myself, and I had to rush before the person arrived.
That’s much more useful than writing:
“I get distracted.”
Do this repeatedly and something important starts to happen.
You begin collecting patterns.
Look for Patterns, Not Perfect Matches
One forgotten appointment doesn’t tell you that you have ADHD.
One overwhelming trip to a grocery store doesn’t tell you that you’re autistic.
One awkward conversation doesn’t tell you much of anything.
But maybe you start noticing that the grocery store isn’t an isolated experience.
You struggle in crowded restaurants.
The television being on while someone talks to you makes it difficult to process what they’re saying.
Certain sounds seem disproportionately intense.
You’ve always cut tags out of shirts.
You need quiet after spending time around people.
Now there’s something to investigate.
The same thing can happen with attention and executive function.
Maybe you don’t simply procrastinate.
Maybe you repeatedly struggle to begin tasks even when you genuinely want to do them.
Maybe deadlines suddenly make tasks possible.
Maybe you depend heavily on reminders.
Maybe you routinely lose track of time.
Maybe you’ve built elaborate systems around remembering things and never stopped to consider why you need those systems in the first place.
The question isn’t:
“Can I make this fit ADHD or autism?”
It’s:
“Is there a recurring pattern here that I didn’t recognize before?”
You May Start Looking at Your Past Differently
This part can sneak up on you.
Once you start recognizing patterns, you may begin remembering things.
School.
Friendships.
Work.
Relationships.
Things your parents repeatedly complained about.
Things teachers wrote on report cards.
Things you’ve always been embarrassed about.
Ways you’ve organized your life that you assumed everyone needed.
You may start reconsidering experiences you previously interpreted as personal failures.
That doesn’t mean every difficult experience you’ve ever had suddenly becomes ADHD or autism.
It means you have new information to consider.
And research suggests that this kind of reinterpretation is common among adults who eventually receive an ADHD diagnosis. The 2026 systematic review of adult ADHD diagnosis experiences found that diagnosis frequently prompted biographical reflection and changes in self-understanding, sometimes increasing self-compassion while also bringing grief, anger, or confusion.1 A 2022 qualitative meta-synthesis similarly found that adults frequently reconsidered years of previously unexplained struggle after diagnosis.2
That process can be complicated.
You don’t have to resolve all of those feelings while you’re still trying to understand what you’re noticing.
For now, keep gathering information.
What Do You Want From This Information?
At some point, it’s worth asking yourself a surprisingly important question:
What am I actually looking for?
There isn’t one required destination.
Maybe you want to understand yourself better.
Maybe you want to learn strategies from ADHD or autistic people who experience the same difficulties you do.
Maybe you want to understand why certain environments overwhelm you.
Maybe something is interfering substantially with your life and you want professional help.
Maybe you’re interested in ADHD medication.
Maybe you need workplace or school accommodations.
Maybe you want a formal ADHD or autism assessment.
Maybe you’re not sure yet.
That’s okay.
You don’t have to decide the destination before you’re allowed to explore the map.
If You See a Practitioner, Bring Your Journal
If you eventually decide to talk with a psychiatrist, psychologist, therapist, primary-care clinician, or other practitioner, bring your notes with you.
Don’t expect yourself to reconstruct decades of your life from memory while sitting in an appointment.
You already did the work.
Bring it.
And keep using the same structure:
What were you doing?
What happened?
How did it impact you?
Instead of only saying:
“I think I have ADHD because I get distracted.”
you can explain:
“This happens several times a week. Here are four examples. Here’s what I was trying to do, here’s what happened, and here’s how it affected my work and home life.”
Instead of only saying:
“I’m really sensitive to noise.”
you can show them what that means in your actual life.
That gives the practitioner something much more useful to investigate.
It also means you aren’t depending entirely on whether the practitioner happens to ask the exact question that unlocks an experience you’ve spent years thinking was normal.
Keep the Conversation About Your Experiences
Unfortunately, practitioner knowledge about adult ADHD and autism isn’t uniform.
The latest systematic review of adults diagnosed with ADHD found persistent barriers and delays in the diagnostic process and substantial variability in the support adults received afterward.1 Research into adult autism has likewise identified problems involving recognition, stereotypes, camouflaging, and assessment practices.3 4
That doesn’t mean a practitioner who disagrees with you is automatically wrong.
It also doesn’t mean you should have to abandon your questions because one person doesn’t immediately see what you’re seeing.
Keep returning to your experiences.
This happens.
This is when it happens.
This is how long I remember it happening.
This is how it affects me.
If they think something else explains those experiences better, that’s useful information too.
Ask them to explain it.
If they rule out ADHD or autism, it’s reasonable to ask:
What makes you think it isn’t ADHD or autism?
What do you think explains these experiences instead?
Do you regularly work with adults being evaluated for ADHD or autism?
Are you familiar with masking or camouflaging in adults?
You’re not trying to win an argument.
You’re trying to understand yourself.
You Don’t Have to Figure Everything Out Today
Maybe you started reading this because ADHD TikTok seemed suspiciously familiar.
Maybe your child was diagnosed.
Maybe someone jokingly asked whether you were autistic and you laughed—and then couldn’t stop thinking about it.
Maybe you’ve simply spent your whole life wondering why certain things seem to work differently for you.
You don’t need to leave here with an answer.
You can leave with better questions.
Take some screening tests.
Notice which questions resonate.
Start your journal.
Write down:
What were you doing?
What happened?
How did it impact you?
Look backward when something reminds you of an earlier experience.
Look forward by continuing to notice what happens.
Don’t force the pieces together.
Just collect them.
Because whether you eventually talk with a practitioner, pursue an assessment, seek support, or simply continue learning, you’ve already done something useful:
You started paying attention to your own experience.
And now you know more about yourself than you did when you started.
