The Kuaya psychiatrist, Dr Norharlina Bahar explains what ADHD is, how to spot it, and the importance of early intervention.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects millions of children worldwide. According to  Dr Norharlina Bahar, a psychiatrist at The Kuaya, the symptoms of ADHD usually begin to surface during a child’s developmental years. Recognising these signs early is essential, as it allows parents and educators to put in place support systems before the child faces significant social or academic setbacks. While every child exhibits high energy at times, ADHD is characterised by persistent patterns that can interfere with daily life.

The Early Symptoms

The early signs of ADHD generally fall into three distinct categories: hyperactivity, impulsivity, and inattentiveness. Hyperactivity is often the most visible trait, characterised by a child who seems driven by motor activity, constantly moving, or unable to remain seated during quiet activities. Impulsivity involves acting on a whim without considering the consequences, such as blurting out answers or interrupting others. Inattentiveness, on the other hand, involves a struggle to maintain focus on a single task, often leading the child to appear not to be listening or to be easily distracted by external stimuli.

Evolution of Symptoms 

As children grow older, the manifestation of these symptoms often evolves. For the majority of children with ADHD, the transition into formal schooling marks a period of increased difficulty. This is when academic challenges become more pronounced. The inability to focus or stay organised is often reflected in a child’s academic results or grades. Beyond the classroom material, the impulsivity associated with ADHD can lead to behavioural issues. Children may find themselves in trouble at school more often because they struggle to follow classroom rules or social norms. When these behaviours begin to interfere with a child’s overall functioning, they become a serious matter that requires parental intervention.

Gender Differences 

One of the most significant insights regarding ADHD is how it differs between genders. For boys, the most common symptom is hyperactivity. Because hyperactive behaviour is often loud and disruptive, it is very obvious to teachers and parents. This visibility is why boys are typically detected and diagnosed much earlier than their peers. Their outward behaviour serves as a red flag prompting adults to seek professional help.

In contrast, girls frequently display inattentiveness as their primary symptom. A girl with ADHD might be viewed as a daydreamer or someone who is simply quiet and distracted. Because this behaviour does not disrupt the classroom or cause immediate problems for others, it often goes unnoticed. Consequently, girls are frequently diagnosed much later in life, often only after they have struggled internally for years without the necessary support.

Importance of Early Intervention

Understanding these early signs and the nuances of how they appear in different children is vital for early intervention. By recognising the subtle differences between a child who is simply energetic and one who is struggling with ADHD, parents can seek the guidance of professionals in order to address it. Early support can help children develop the tools they need to navigate their academic and social lives successfully, ensuring that the disorder does not define their lives and future potential.
