Adult ADHD, Late Diagnosis and Self-Understanding: A Psychologist’s Perspective
Do I Have ADHD — Or Am I Just Not Trying Hard Enough?
If you have ever found yourself wondering, “Do I have ADHD, or am I just disorganised, forgetful, lazy, or not trying hard enough?” — you are not alone.
It is a question many adults quietly carry, often after years of self-doubt, frustration, and trying harder than those around them may ever realise.
As a psychologist working in ADHD assessment and therapy in Brisbane, I have supported many adults asking this exact question.
I have also asked it myself.
My Experience with Late ADHD Diagnosis
I was diagnosed with ADHD in adulthood.
Like many adults diagnosed later in life, I could recognise the traits in myself for years — but I minimised them. I told myself:
· I just need to be more organised
· My memory is just terrible
· I need to try harder
Like many neurodivergent adults, I reframed real challenges as personal failings.
It was only after my child was diagnosed, and a paediatrician noted that ADHD often runs in families, that I began to look more closely at my own experience.
Research now strongly supports the genetic component of ADHD, which helps explain why many adults only recognise it in themselves later in life.
Is ADHD Over-diagnosed — Or Better Recognised?
There is increasing public conversation around adult ADHD — and unfortunately, a lot of misinformation.
You may have heard:
· “Everyone has ADHD now”
· “It’s overdiagnosed”
· “It’s just a trend”
These messages can be harmful. They can stop people from seeking support out of fear of being dismissed.
Yes, ADHD diagnoses have increased — including in Australia.
But this does not mean people are making it up.
It more often reflects:
· Better awareness of ADHD
· Improved understanding of how it presents (especially in women and high-masking individuals)
· Recognition of people who were previously missed
Recognition is not over-diagnosis.
Sometimes, it is delayed diagnosis.
What ADHD Actually Looks Like in Adults
ADHD is often misunderstood and reduced to stereotypes.
It is not just:
· The disruptive child
· The impulsive risk-taker
· The “lazy” adult
ADHD can present in different ways:
· Inattentive presentation: forgetfulness, disorganisation, losing things, difficulty starting tasks
· Hyperactive/impulsive presentation: restlessness, talking excessively, interrupting
· Combined presentation: a mix of both
For many adults, it looks like:
· Chronic overwhelm
· Procrastination
· Difficulty following through
· Feeling mentally “busy” but stuck
ADHD and Executive Functioning
ADHD is increasingly understood through the lens of executive functioning — the mental processes that help you:
· Plan and organise
· Manage time
· Regulate emotions
· Shift attention
· Follow through on tasks
This is why so many people say:
“I know what I need to do… I just can’t seem to do it.”
That gap between knowing and doing can be incredibly distressing.
ADHD is often described as a performance disorder, not a knowledge disorder.
It is not about intelligence or capability.
It is about the brain’s ability to consistently activate those skills.
The Brain and ADHD
Research suggests ADHD involves differences in:
· Dopamine (motivation and reward)
· Noradrenaline (attention and alertness)
This helps explain why:
· Tasks that feel boring can feel impossible
· Urgent or interesting tasks can feel easy
This is also why stimulant medication is often considered an evidence-based treatment, when appropriate and prescribed by a medical professional.
Why Medication Is Not the Whole Story
Medication can support:
· Attention
· Focus
· Regulation
But it does not:
· Heal years of shame
· Undo masking or overcompensation
· Change perfectionism or people-pleasing patterns
· Address burnout
Many adults with ADHD carry a long history of misunderstanding themselves.
This is where therapy becomes important.
How Therapy Can Help with ADHD
Therapy for ADHD is not just about managing symptoms.
It can help you:
· Understand how ADHD shows up in your life
· Build practical strategies for executive functioning
· Reduce overwhelm and burnout
· Work through unhelpful beliefs (e.g., “I’m lazy” or “I’m failing”)
· Develop self-compassion
At MindCare Clinics in Paddington, Brisbane, we use approaches such as:
· Cognitive Behavioural Therapy (CBT)
· Acceptance and Commitment Therapy (ACT)
· Schema-informed therapy
A Different Way of Responding to Yourself
For me, ADHD sometimes looks like double-booking events — even with a calendar.
In the past, that might have sounded like:
“I’m terrible. I’m a bad friend. I can’t even get this right.”
Now it sounds more like:
“You double-booked again. You didn’t do it intentionally. This is part of how your brain works. Let’s repair it and move forward.”
That shift matters.
That is self-compassion.
Signs It Might Be Worth Exploring ADHD
If you:
· Know what you should be doing but struggle to follow through
· Feel constantly overwhelmed or behind
· Work twice as hard to appear organised
· Feel exhausted from holding everything together
It may not be laziness.
It may be worth exploring whether ADHD or another neurodevelopmental difference is part of your experience.
