Understand Why You're Seeking an ADHD Diagnosis
Before starting your journey toward an ADHD diagnosis, it's important to reflect on your motivation. Whether you're struggling to manage focus, impulse control, or organisation—or you’re supporting a loved one—it’s helpful to understand how ADHD might be affecting daily life.
If you suspect ADHD, learning about its symptoms is a key first step.

Recognising ADHD Symptoms
ADHD can manifest in different ways depending on age and subtype. No two people experience it the same way. For this reason, it's crucial to explore how your specific experiences align with recognised symptoms.
Inattentive-Type ADHD Symptoms
Individuals with primarily inattentive ADHD may experience:
Difficulty maintaining focus on tasks
Frequent forgetfulness
Disorganisation
Being easily distracted
Making careless mistakes
Overlooking important details
If you regularly face challenges like these, it might be time to consider a professional assessment.
Hyperactive/Impulsive-Type ADHD Symptoms
People with hyperactive or impulsive traits may display:
Excessive talking or interrupting
Trouble sitting still or frequent fidgeting
Impatience or difficulty waiting for their turn
Impulsive behaviour or decision-making
Difficulty staying quiet in appropriate settings
These behaviours can be disruptive and emotionally draining when left unaddressed.
Why a Diagnosis Matters
An ADHD diagnosis can be the first step toward meaningful support, whether that means medication, therapy, workplace accommodations, or educational resources. Diagnosis provides clarity and validation, helping you move forward with confidence.
