Understanding Adult ADHD and What an ADHD Assessment Can Tell You

A lot of adults who come to us for ADHD testing aren’t sure they have ADHD.

They might say things like:

“I did well in school, so I don’t think I could have ADHD.”

“I can focus when something is really important.”

“I’m actually incredibly organized.”

“I get everything done. It just takes me forever.”

Or simply: “Maybe I’m just overwhelmed.”

These are reasonable questions. ADHD does not always look like someone who can’t sit still or can’t pay attention. Especially in adults who have spent years developing ways to compensate, ADHD can be much less obvious from the outside.

Some people with ADHD are successful students and professionals. Some are highly organized. Some are perfectionists. Some have developed such elaborate systems for managing themselves that other people would never guess how much effort it takes.

As psychologists who assess and treat ADHD at California Psychology Center, we are often interested not only in whether someone is functioning, but how hard they are working to function that way.

What Actually Counts as ADHD?

ADHD is a neurodevelopmental condition involving persistent difficulties with attention and/or hyperactivity and impulsivity.

The DSM-5-TR divides ADHD symptoms into two main groups.

Inattention 

Symptoms include:

  • Frequently making careless mistakes or missing details
  • Difficulty sustaining attention
  • Appearing not to listen when someone is speaking directly to you
  • Difficulty following through on tasks
  • Difficulty organizing tasks and responsibilities
  • Avoiding or putting off tasks that require sustained mental effort
  • Frequently losing things
  • Being easily distracted
  •  Being forgetful in everyday life

Hyperactivity and Impulsivity

Symptoms include:

  • Fidgeting or difficulty sitting still
  • Getting up when remaining seated is expected
  •  Feeling restless
  •  Difficulty doing things quietly
  • Feeling constantly “on the go”
  • Talking excessively
  •  Answering before someone has finished asking a question
  •  Difficulty waiting your turn
  •  Interrupting other people

For adults age 17 and older, the DSM-5-TR requires at least five symptoms in one or both categories.

But ADHD assessment is not simply a matter of counting symptoms.

We also want to know when these patterns started. ADHD begins in childhood, even when it wasn’t recognized at the time. Symptoms should also show up across more than one part of life and cause meaningful difficulty.

That history is one of the reasons a good ADHD evaluation can be so helpful.

“But I Did Well in School”

This is probably one of the most common reasons adults dismiss the possibility of ADHD.

You absolutely can have ADHD and have done well academically.

Intelligence, family structure, anxiety, perfectionism, natural interest in school, and strong compensatory strategies can all help someone manage ADHD symptoms.

Sometimes college is actually when those strategies begin to break down.

In high school, your day may have been structured for you. You knew where you had to be every hour. Teachers reminded you about assignments. Parents helped create routines. Deadlines were relatively frequent and concrete.

Then college asks you to manage much more of that structure yourself.

Suddenly you have a paper due three weeks from now, nobody cares whether you start it tonight, your sleep schedule is yours to manage, and you have six different places where professors post information.

For a brain that struggles with executive functioning, that can be a big shift.

ADHD Can Hide Behind Really Good Coping Strategies

Many adults with ADHD have spent years figuring out ways to compensate for their difficulties.

Sometimes this is referred to as masking.

You might:

  • Put absolutely everything in your calendar
  • Set multiple alarms so you don’t forget things
  •  Check your work repeatedly because you don’t trust yourself not to miss something
  • Arrive very early because being late feels too risky
  • Work much longer than other people on the same assignment
  • Depend heavily on lists and reminders
  •  Wait until a deadline creates enough pressure to finally get started
  • Become extremely organized because you know what happens when you aren’t

These strategies can work remarkably well.

But sometimes they work at a pretty high cost.

Someone can look extremely competent while internally feeling like they are constantly trying to keep twelve plates spinning.

This is why one of the questions I find useful is not just:

Can you get everything done? 

It is:

What does it take for you to get everything done? 

ADHD and Perfectionism Can Go Together

People don’t always associate ADHD with perfectionism, but we see the two together quite often.

If you have learned over time that you sometimes forget things, miss details, or make mistakes when you’re moving quickly, becoming extremely careful makes sense.

You check the email again.

You reread the assignment.

You overprepare for the presentation.

You spend three hours on something that probably needed one.

And if these strategies have helped you succeed, it can be hard to recognize them as compensatory strategies at all. They may simply feel like part of your personality.

The problem is that maintaining that level of vigilance can be exhausting.

Why Do I Wait Until the Last Minute?

Procrastination is another extremely common ADHD experience.

And it can be especially confusing because people with ADHD often procrastinate on things they genuinely care about.

You know the paper matters.

You want to start it.

You’ve been thinking about starting it for four days.

And somehow you still aren’t starting it.

ADHD affects executive functioning, including our ability to initiate tasks, organize behavior, manage time, hold information in mind, and direct attention toward something that does not provide an immediate reward.

Then the deadline gets close.

Now there is urgency.

Your adrenaline kicks in. Suddenly you can focus.

You write the paper in five hours.

Maybe you even get an A.

And unfortunately, your brain gets another piece of evidence that waiting until the last minute “works.”

That cycle can continue for years.

The Self-Criticism That Often Comes With ADHD

One of the harder parts of untreated or unrecognized ADHD is the story people can develop about themselves.

“I’m lazy.”

“I have no discipline.”

“Why can everyone else just do things?”

“I have so much potential. Why can’t I get it together?”

After hearing versions of these messages from yourself or other people for years, they can start to feel like facts.

They aren’t particularly useful facts, though.

If the problem is executive functioning, calling yourself lazy does not improve executive functioning.

In fact, shame can make avoidance and procrastination worse.

Part of good ADHD treatment is learning practical skills. But another important part can be developing a more accurate and compassionate understanding of yourself.

Self-compassion doesn’t mean deciding it doesn’t matter if you miss every deadline.

It means replacing “I’m a disaster” with something closer to, “Starting tasks is hard for my brain. What can I put in place that makes starting easier?”

That gives you something to work with.

Could It Still Be Something Other Than ADHD?

Yes, and this is one reason we don't diagnose ADHD from a checklist alone.

Anxiety, depression, trauma, sleep problems, chronic stress, and burnout can all affect attention and executive functioning. And sometimes people have ADHD and one or more of these concerns.

A thoughtful evaluation looks at the whole picture.

But if you’ve had longstanding patterns of procrastination, distractibility, forgetfulness, difficulty initiating tasks, restlessness, impulsivity, or needing an unusual amount of structure to stay on top of life, ADHD is certainly worth exploring.

What Can You Actually Do About ADHD?

This is the part I wish more people knew.

There is a lot we can do.

ADHD treatment is not about magically turning someone into a person who remembers everything, loves boring tasks, and never gets distracted.

It is about understanding how your attention and executive functioning work and building systems that make life easier.

Learning Executive Functioning Skills 

People with ADHD can learn concrete strategies for things like:

  • Breaking large tasks into much smaller starting steps
  •  Creating realistic daily plans
  • Prioritizing instead of treating everything as equally urgent
  • Estimating how long things actually take
  • Using calendars and reminders more effectively
  • Creating external deadlines
  • Reducing distractions
  •  Building routines
  • Creating consistent places for important belongings
  • Using accountability to help with task initiation
  •  Recognizing when perfectionism is making a task unnecessarily difficult

One of the central ideas is to stop expecting your brain to hold everything internally.

Put it outside your brain.

Put it on the calendar. Set the alarm. Make the list visible. Create the deadline. Ask someone to check in.

The goal isn’t to prove that you shouldn’t need these things.

The goal is to build a life that works.

What About Medication?

Medication is also one of the main evidence-based treatments for ADHD.

Stimulant medications are commonly used, and there are also non-stimulant options. For many people, medication can make it substantially easier to regulate attention and use the executive functioning skills they are learning.

Medication isn’t right for everyone, and those decisions should be made with an appropriate prescribing healthcare professional.

It is also not an either/or decision between medication and learning skills.

For many adults, the two can work very well together.

What We Look at in an ADHD Assessment

When we developed our adult ADHD testing clinic at California Psychology Center, one thing that felt important was that the evaluation be useful beyond simply answering:

Do I have ADHD: yes or no? 

Of course we want to answer that question carefully.

But we also want someone to come away understanding themselves better.

Why do you procrastinate?

What happens when you try to start something?

Are you relying on anxiety or perfectionism to compensate for attention difficulties?

What executive functioning skills are particularly difficult for you?

Where are you getting stuck?

And importantly, what can you actually do differently?

Sometimes receiving an ADHD diagnosis is incredibly validating. Experiences that someone has interpreted for years as laziness or lack of discipline suddenly make much more sense.

And even when ADHD is not the answer, a good evaluation should still give you useful information about what is getting in your way.

ADHD Testing and Treatment at California Psychology Center 

California Psychology Center offers adult ADHD testing, including evaluations for college students and adults who may have gone years without recognizing ADHD.

Our ADHD evaluations are fully covered for eligible clients with Aetna insurance and eligible Stanford students with Wellfleet insurance.

We also offer individual therapy and an ADHD skills group, covered by insurance for eligible clients, where we work on the practical side of living with ADHD: executive functioning, procrastination, organization, planning, emotional regulation, and developing a less critical relationship with yourself.

If you’ve been wondering whether you have ADHD, you don’t need to already know the answer before getting evaluated. That’s the point of the evaluation.

You may have ADHD. You may have developed some incredibly effective ways of compensating for it. You may also have picked up a lot of self-criticism along the way.

Understanding what’s actually happening can be a relief.

And more importantly, once you understand the pattern, there are very concrete things you can do to make life easier.
