Adult ADHD Diagnosis: What I Learned from Shadowing a Psychiatrist in Private Practice

Ever wondered what actually happens during an adult ADHD assessment? Recently, I had the chance to shadow a consultant psychiatrist in private practice, and it turned out to be one of the most eye-opening experiences of my career.

Over several weeks, I sat in on assessments and follow-up appointments involving ADHD, autism, anxiety, PTSD, insomnia, depression and more. One thing became clear very quickly: mental health rarely fits into neat little boxes.

Most people don’t show up with “pure” ADHD or “just” anxiety. Instead, symptoms often overlap, blend together, and reveal a much more interesting and complex story. Here are some of the biggest things I learned.

Why Adult ADHD Is Often Missed

One of the most surprising things I noticed was just how often ADHD sits quietly in the background without anyone realising it. Many adults had been treated for anxiety, depression or stress for years, but few had explored the possibility of ADHD. Some described feeling overwhelmed or disorganised their whole lives, yet it had never been connected to difficulties with attention or executive functioning.

This came up particularly often with women and older adults. Hyperactivity in adulthood doesn’t usually look like bouncing off walls it can look like:

• internal restlessness

• constant overwhelm

• difficulty prioritising

• struggling to stay focused

Without a careful assessment, these experiences can be easily mistaken for anxiety alone.

The Connection Between ADHD and Anxiety

Another big theme was how closely linked ADHD and anxiety can be. Many people attending appointments talked about high levels of anxiety, but the anxiety often stemmed from the constant effort required to stay organised, focused and on top of everyday tasks. When your brain works twice as hard just to manage the basics, anxiety is a pretty understandable response.

In several cases, once ADHD was treated, people noticed their anxiety reducing too. That really challenged the idea that anxiety is always the “main problem.” Sometimes it’s a reaction to living with untreated ADHD.

Medication Isn’t a Quick Fix

Medication came up a lot, especially when ADHD was diagnosed. Stimulants like lisdexamfetamine were commonly discussed, but what stood out was how collaborative and gradual the process was. There was no “magic dose” or one-size-fits-all answer. Instead, people worked with the psychiatrist to carefully adjust the dose until everyday functioning not just symptoms started to improve. Physical checks like weight, blood pressure and pulse were an essential part of the process too.

Medication was always seen as one piece of the puzzle, not the whole solution. Therapy, such as CBT or trauma-focused approaches was often recommended later on to support longer-term change.

Why Diagnosis Can Be Complex

ADHD symptoms overlap with so many other conditions: autism, anxiety, trauma responses, sleep problems and certain personality traits. This means clinicians can’t just tick boxes on a checklist. A thorough assessment involves:

• developmental history

• clinical judgement

• understanding someone’s life context

• looking at the “whole picture,” not isolated symptoms

Watching this reinforced how important a biopsychosocial approach truly is. Diagnosis isn’t about fitting someone into a label; it’s about understanding their story.

The Power of Psychoeducation

One of the most meaningful parts of the consultations was the way the psychiatrist explained what ADHD actually is, how it affects concentration, executive functioning and emotional regulation. For many people, that explanation alone brought enormous relief. Realising “this isn’t my fault” can be life-changing.

The same was true in consultations about trauma. Understanding how the brain responds, especially in PTSD, helped people feel less confused and less alone, and opened the door to effective treatments like EMDR and trauma-focused CBT.

Focusing on Everyday Life

What I loved most was the consistent focus on helping people live more manageable and fulfilling lives. Treatment decisions weren’t only about reducing symptoms. They were about:

• improving work or study

• strengthening relationships

• reducing overwhelm

• increasing sense of control

• helping people feel more capable in their daily routines

Because in the end, that’s what mental health care is really about, supporting people to live the life they want.

Final Thoughts

Shadowing psychiatric practice gave me such a valuable insight into how adult ADHD is recognised and treated. It showed me how often ADHD goes unnoticed, especially when it’s wrapped up in anxiety or other difficulties.

But it also highlighted something hopeful; with thoughtful assessment, collaborative treatment and good psychoeducation, many people finally understand themselves in a new and empowering way.

And that, to me, is the heart of good mental health care. Curiosity, compassion and a genuine willingness to understand each person’s unique story.
