The Complete Guide to ADHD in Adults

What Is ADHD in Adults?

Attention Deficit Hyperactivity Disorder is one of the most common neurodevelopmental conditions, affecting an estimated 2.5-4% of adults worldwide. Yet for many adults, especially those in Hong Kong’s fast-paced environment, ADHD goes unrecognised for decades.

In my practice, I regularly see adults in their 30s and 40s who are only now realising that the struggles they’ve faced their entire lives have a name. The relief that comes with understanding — “it’s not that I’m lazy, or broken, or not trying hard enough” — can be profound.

The Three Presentations of ADHD

ADHD presents differently in different people. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) identifies three presentations:

Predominantly Inattentive

This is the presentation most often missed, particularly in women and girls. Symptoms include difficulty sustaining attention, frequent careless mistakes, trouble organising tasks, losing things, and being easily distracted. You might appear to be “daydreaming” or seem like you’re not listening when spoken to.

Predominantly Hyperactive-Impulsive

This presentation is characterised by fidgeting, difficulty staying seated, talking excessively, interrupting others, and acting without thinking through consequences. In adults, the physical hyperactivity often manifests as internal restlessness rather than the bouncing-off-walls image people associate with ADHD.

Combined Presentation

Many adults with ADHD show features of both inattention and hyperactivity-impulsivity. This is the most common presentation.

Beyond the Stereotypes

ADHD in adults looks very different from the hyperactive child in a classroom. In my experience, adult ADHD often shows up as:

• Executive dysfunction — difficulty starting tasks, switching between tasks, or completing projects despite wanting to
• Emotional dysregulation — intense reactions to everyday situations, difficulty managing frustration, rejection sensitivity
• Time blindness — consistently underestimating how long tasks take, chronic lateness despite best efforts
• Hyperfocus — losing hours in an activity that captures your interest while struggling to give five minutes to something that doesn’t
• Masking — developing elaborate coping strategies that hide your struggles from others at enormous personal cost

How ADHD Affects Daily Life in Hong Kong

Hong Kong’s high-pressure environment can make ADHD symptoms particularly challenging. The expectations around work performance, academic achievement, and social behaviour are intense. Many of my clients describe feeling like they’re constantly performing — pretending to be someone they’re not just to get through the day.

Common challenges I see in my Hong Kong clients include:

• Overwhelming workloads that require sustained focus and organisation
• Social expectations that leave little room for neurodivergent ways of being
• The stigma around mental health and neurodevelopmental conditions
• Difficulty accessing appropriate assessment and support
• Burnout from years of compensating for undiagnosed ADHD

Getting an ADHD Assessment

If you recognise yourself in what you’ve read so far, you might be wondering about getting assessed. In Hong Kong, ADHD assessment for adults is available through psychiatrists and clinical psychologists. The process typically involves:

1. Clinical interview — a detailed discussion about your current challenges and developmental history
2. Standardised questionnaires — rating scales that measure ADHD symptoms
3. Collateral information — input from family members or partners (when possible)
4. Rule out other causes — ensuring symptoms aren’t better explained by anxiety, depression, or other conditions

It’s worth noting that you don’t need a formal diagnosis to benefit from therapy. Many of the strategies and skills we work on in ADHD therapy are helpful regardless of whether you have a diagnosis on paper.

Treatment Options

ADHD management typically involves a combination of approaches:

Therapy

Therapy for ADHD focuses on practical strategies and skill-building rather than simply talking about your feelings. In my practice, I use DBT skills (particularly emotion regulation and distress tolerance), executive function coaching, and self-compassion work.

Medication

Stimulant and non-stimulant medications can be effective for managing ADHD symptoms. Medication is prescribed by psychiatrists, not counsellors. Many of my clients find that therapy and medication work best in combination — medication helps with the neurological aspects while therapy builds the skills and strategies.

Lifestyle Adjustments

Small changes in routine, environment, and habits can make a significant difference. We work together to identify what adjustments will have the biggest impact for your specific situation.

Therapy for Adult ADHD: What It Actually Looks Like

Therapy for ADHD isn’t about sitting on a couch talking about your childhood (unless that’s what you need). It’s practical, skills-based, and focused on the things that matter to you right now.

In sessions, we might work on:

• Understanding how your ADHD brain works and why certain things are hard
• Building systems that work with your brain, not against it
• Developing emotional regulation skills
• Addressing the shame and self-criticism that often comes with undiagnosed ADHD
• Improving relationships affected by ADHD symptoms
• Unmasking — figuring out who you actually are underneath the coping strategies

When to Seek Help

You don’t need to be in crisis to start therapy. If ADHD symptoms are affecting your work, relationships, self-esteem, or quality of life, that’s reason enough. If you’ve been told you’re “lazy” or “not trying hard enough” your whole life and it never quite felt right, that’s reason enough too.
