What is ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders. Often diagnosed in childhood, it is now more prevalent among adults and is characterised by a persistent pattern of inattention and or hyperactivity-impulsivity that can interfere with functioning or development, as outlined in the DSM-V.

Diagnosing ADHD

To diagnose ADHD, practitioners in Western Medicine typically rely on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM)*. This handbook provides a standardised set of guidelines for identifying and diagnosing mental disorders, including ADHD.

According to the DSM-V, there are three different presentations of ADHD – or three types of ADHD – each characterised by the predominant symptoms exhibited by the individual: inattentive presentation, hyperactive-impulsive presentation, and combined presentation.

In this type of ADHD, features revolve around attention difficulties. People might find it hard to stay focused on tasks or activities, often making errors due to carelessness. Following instructions can be challenging, and they may appear forgetful or easily distracted. Organisation and time management might also be tough. Compared to other types, symptoms related to hyperactivity and impulsivity are usually less noticeable in this presentation. Do you have ADHD inattentive? Find out now.

In this type of ADHD, features revolve around hyperactive and impulsive symptoms. People might struggle to stay seated, frequently fidgeting or moving around restlessly. They may interrupt others in conversation, find it hard to wait their turn, and act impulsively without thinking through the consequences. Symptoms related to inattention usually take a back seat in this presentation. Do you have ADHD Hyperactive/Impulsive? Find out now.

In this type of ADHD, features involve a blend of symptoms including inattention, hyperactivity, and impulsivity.

FAQs about ADHD

According to the DSM-5, ADHD is more frequently diagnosed in boys than in girls. Boys are more likely to display hyperactive and impulsive symptoms, which are more noticeable and often lead to earlier diagnosis. Girls with ADHD tend to exhibit inattentive symptoms, which can be subtler and, as a result, are often overlooked or diagnosed later. The criteria in the DSM-5 apply to both boys and girls, but the presentation of symptoms may differ between genders.

ADHD treatment often involves a combination of behavioural therapy and medication. Stimulant medications like methylphenidate (e.g., Ritalin) and non-stimulants are commonly used to manage symptoms. Behavioural interventions, such as cognitive behavioural therapy (CBT), help with developing coping strategies. Treatment plans are typically tailored to the individual’s needs, focusing on improving functioning in daily activities.

While the exact cause of ADHD is unknown, the DSM-5 suggests that genetics play a significant role. Environmental factors, prenatal exposure to toxins, low birth weight, and brain injury may also contribute. ADHD is linked to the way certain neurotransmitters (like dopamine) function in the brain, affecting attention and impulse control. The DSM-5 recognises that ADHD is a neurodevelopmental disorder, and it often runs in families.

An ADHD diagnosis is based on the criteria in the DSM-5, which require that symptoms must appear before age 12 and occur in more than one setting (e.g., home, school, or work). A clinician, such as a psychologist,  psychiatrist or paediatrician will conduct a thorough assessment that includes observation, interviews, and reviewing the person’s history. The symptoms must also significantly interfere with social, academic, or work performance and cannot be better explained by another mental health condition.

ADHD symptoms often include difficulties with focus, forgetfulness, restlessness, and acting without thinking. These traits can fall into two categories: inattentiveness (struggling to concentrate) and hyperactivity/impulsivity (being overly energetic or acting quickly without thought). Many people experience a mix of both.


*The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) is the gold standard used by Psychologists and Psychiatrists to diagnose mental health conditions. Created by the American Psychiatric Association, it’s a globally recognised guide that outlines the criteria for conditions like ADHD, Autism, and Bipolar Disorder and more. The most recent edition, the DSM-5-TR, was released in 2022.

DSM-5-TR offers detailed descriptions of various mental disorders, including their symptoms, prevalence, course, and associated features. It serves as a crucial reference for clinicians, researchers, educators, and policymakers in the field of mental health.

This manual helps clinicians accurately identify and diagnose mental health conditions, guiding treatment planning and interventions. It also facilitates communication among professionals by providing a common language and framework for understanding and discussing mental health disorders.


DSM-5-TR is periodically updated to reflect advancements in scientific understanding, changes in diagnostic criteria, and emerging trends in mental health research. It plays a vital role in shaping clinical practice, research initiatives, and public health policies related to mental health and psychiatric disorders.
