Attention deficit hyperactivity disorder (ADHD) manifests in two primary clusters of behavioural issues:

Inattentiveness

Challenges with focusing and maintaining concentration.

Hyperactivity and Impulsivity

Excessive energy and acting without thought.

Although many individuals experience symptoms across both categories, this isn't always the case. About 20% to 30% of people only struggle with inattentiveness, a subtype often referred to as attention deficit disorder (ADD).

This can be more elusive to diagnose as the symptoms are less disruptive.

Interestingly, gender can play a role in diagnosis. ADHD is more frequently diagnosed in boys, but girls tend to predominantly show inattentive symptoms, making their condition less apparent and potentially leading to under diagnosis.

Symptoms in Children and Teens

ADHD symptoms generally become apparent before a child reaches six years old and manifest in multiple settings like home and school. Children may exhibit :

Inattentiveness

Hyperactivity and Impulsivity

These symptoms can lead to academic underperformance, strained social interactions, and disciplinary issues.
