Let’s talk about Adult ADHD Treatment in Penang & Malaysia

In recent years, I’ve had many adults walk into my clinic in Penang asking if they might have undiagnosed ADHD (Attention Deficit & Hyperactivity Disorder). These are not just people who struggled at school — in fact, many of them had excellent academic results. And many of them alumni of elite school in Penang such as Chung Ling, PCGHS, Jit Sin, Free School etc.

Their stories often share a common theme: they’ve noticed attention difficulties since childhood, but were still able to thrive at school — either because of their intelligence or because of a highly structured study environment provided by the school system or watchful parents.

Things became more challenging when they moved on to college, university, and work. Tertiary study and the workplace rarely provide the same kind of structure; instead, they require them to manage their own time, set their own priorities, and self-direct their focus.

Suddenly, these individuals found themselves struggling to meet deadlines. They often described it as “procrastination,” but in reality, they found it very difficult to start tasks that felt far away in the future. Motivation only came when the deadline was looming.

Many also described their minds as feeling like “watching 10 TV streams at once” — constantly thinking about multiple things simultaneously. They get easily distracted in conversations, their minds wandering off at a gesture or a passing comment. Misplacing their wallet happens more times than they can count. They rely on checklists for daily life, even just to leave a place without forgetting something behind.

They began to wonder: “Could it be ADHD?”, but getting answer is often not easy.

Sometimes they learn about ADHD from an Instagram Reel or TikTok; other times, it’s a friend who points it out to them. That starts their journey to seek answers and treatment that can help them manage their adult life.

However, for many adults, the path to ADHD assessment and treatment is not straightforward.

Some doctors still see ADHD as a diagnosis exclusive to children and are reluctant to assess or diagnose it in adults. Moreover, high achievers who struggle with attention and focus — and who have learned to compensate using systems, workarounds, and sacrifices — often have their difficulties dismissed. Many doctors jump to the conclusion that anyone with relatively good academic performance could not possibly have ADHD. (Emphasis: That’s not true — good academic achievements does not exclude ADHD.)

Diagnosing Adult ADHD can be very tricky

With all that said, I’ve to confess that diagnosing adult ADHD is often very tricky.

You see, as with many conditions in psychiatry, everything exists on a spectrum. Spotting the severe cases is easy; it’s the mild ones that make clinical judgement more challenging.

Severe ADHD in children is usually obvious.

This is the little boy whose teacher has written three letters pleading with his parents to bring him to see a psychiatrist; who has burnt out his parents; who is climbing my clinic chair while waiting for his turn, and is now playing with the faucet in my room while his exhausted mother vents about how difficult it is to manage him.

Children like this don’t really need a psychiatrist to “discover” their ADHD — everyone in their lives already knows it. The good news is that their path to treatment is usually short and direct. A paediatrician, family doctor, or psychiatrist would have started helping early on with a combination of medication and/or psychological and behavioural interventions.

The mild cases, however, are the ones that often get missed — like the quiet little girl who seems absent-minded; who is desperate to get good grades but just can’t focus when studying; who still achieves great things but often wonders why everyone else seems to manage it effortlessly while she has to struggle and barely get there.

When we evaluate these cases, different psychiatrists may sometimes disagree on the diagnosis. Some symptoms are ambiguous or inconsistent, making it hard to reach a confident clinical conclusion.

Symptoms of adult ADHD

ADHD isn’t just a childhood condition — many people still have symptoms as adults, though they may look a bit different from what you’d expect in children. Some common signs in adults include:

• Easily distracted: Your mind often jumps to other things, even in the middle of a conversation or task.
• Trouble finishing tasks: You start projects with energy but struggle to follow through to the end.
• Procrastination: Putting things off until the last minute, even when you know it will cause stress later.
• Poor time management: Losing track of time, missing deadlines, or underestimating how long things will take.
• Forgetfulness: Misplacing your phone, wallet, or keys; forgetting appointments or tasks.
• Difficulty prioritising: Struggling to decide what to do first, especially when there’s a long to-do list.
• Restlessness: Feeling like you can’t relax, always needing to be “doing something.”
• Impulsivity: Saying or doing things without thinking, or making quick decisions you later regret.
• Emotional ups and downs: Getting frustrated, irritated, or overwhelmed more easily than others.

Not everyone with ADHD has all these symptoms, and some may be stronger than others. What matters is whether these patterns have been present since childhood and are affecting your daily life — at work, at home, or in relationships.

Reluctance to Diagnose & to Prescribe Stimulants (Methylphenidate)

This reluctance to diagnose often goes hand in hand with hesitation to prescribe treatment.

In Malaysia, many doctors are cautious about prescribing stimulant medication, such as Methylphenidate, for adults — and for good reason. There are concerns about potential misuse, which, while not widespread, can still occur. (I’m not going to elaborate the “how & why” of misuses here, so as not to give unnecessary publicity to it.)

Another important consideration is that what patients perceive as ADHD-related inattention can sometimes be caused by anxiety, depression, or burnout — conditions that are far more common causes of new-onset attention difficulties in adulthood. This is why a careful and thorough assessment is so important before starting any treatment.

Limited treatment options in Public Sector

Another struggle we hear from patients across Malaysia is the limited medication options available in government hospitals. Certain ADHD medications, like Atomoxetine and extended-release Methylphenidate, are considered “quota medications” in the public healthcare system. This means they are available in limited amounts, and sometimes you simply have to be lucky to receive them.

That said, it’s important to acknowledge that government hospitals and psychiatry clinics do an outstanding job of providing care to a vast number of people with ADHD and other psychiatric conditions — treatments that could easily cost a few hundred ringgit a month privately — for a flat fee of just RM5.

For adults in the public sector, however, this often means they may not have access to these longer-acting options. This can be frustrating, especially for those who cannot tolerate short-acting versions or who need all-day symptom coverage.

Treatment Options for ADHD in Malaysia

1. Medication Treatment for ADHD

Medication is often one of the most effective treatments for ADHD, especially when symptoms significantly interfere with daily life.

It helps our patients juggle different responsibilities in life — work, studies, and relationships. And when it’s important to stay focused — for example, during an exam or when handling important projects — it’s always reassuring to have the option to take (or not take) the medication on that particular day.

For example, a manager reported that it became easier to keep up with the proper paperwork — a task that had previously overwhelmed him. A teacher shared that it was easier for her to initiate tasks, such as marking test papers, which had previously left her feeling paralysed. And a restaurant worker shared that she felt less frustrated and stressed during peak hours when she was on her medication.

In Malaysia, the commonly used ADHD medications include:

• Methylphenidate (short-acting and extended-release)
• Atomoxetine (a non-stimulant)

Both short-acting Methylphenidate and Atomoxetine are available in Malaysia, though access can differ between the public and private sectors. As of time of writing, Extended-release Methylphenidate and Atomoxetine are considered “quota medications” in government hospitals, meaning their availability is limited.

It’s worth noting that Adderall — a mixed amphetamine salt commonly prescribed for ADHD in some countries — is not available in Malaysia, in either the public or private sector.

Benefits adults often notice when the medication is working well:

• Improve focus: It’s easier to stay on task without the mind constantly wandering.
• Start and finish tasks: Less procrastination, with better follow-through to get things done.
• Feel less drained: More mental energy, even for routine or less exciting work.
• Stay steady: Fewer mood swings and less acting on impulse.
• Manage time better: Easier to plan ahead and meet deadlines.

Possible Side Effects of Methylphenidate:

• Trouble sleeping (especially if taken too late in the day)
• Loss of appetite or weight loss
• Increased heart rate or higher blood pressure
• Headache
• Stomach upset or nausea
• Dry mouth
• Feeling jittery, anxious, or restless
• Mood changes, such as irritability
• Dizziness
• Slower growth in children (height & weight) — Effecting <1/10 childrens

2. Non-Medication Approaches

Medication isn’t the only way to manage ADHD. Many people find that learning practical skills and strategies makes a big difference in their daily life. These are some examples:

• Understanding ADHD: Knowing how ADHD affects the brain helps us plan our life better, set realistic expectations, and create strategies that work for us.
• Building focus: Learning different techniques to improve attention, manage distractions, and stay on task.
• Managing emotions and impulses: Using psychological tools to handle frustration, reduce anger, and control impulsive actions.
• Getting organised: Creating routines, checklists, and systems that make it easier to remember tasks and meet deadlines.

These skills are usually taught by counsellors or clinical psychologists, and sometimes psychiatrists may also share certain techniques during consultations. Even if you’re on medication, these strategies can make your day-to-day life smoother and more manageable.

Final Thoughts

If you see yourself in these stories — difficulty focusing, struggling with deadlines, constant distraction — it may be time to get checked for ADHD or other attention issues.

Many people who make it to adulthood despite having ADHD leave the psychiatry clinic feeling relieved — now equipped with more tools and options to manage their focus, productivity, and emotions. Getting an ADHD diagnosis as an adult is like finally receiving a manual for how your brain works, along with a set of tools you can choose from to better manage it.
