What Tests Are Used to Diagnose Inattentive ADHD?

An ADHD diagnosis for the inattentive subtype involves more than ticking boxes, it’s a structured process using multiple tools to assess attention, memory and executive function. Because symptoms like daydreaming, disorganisation and forgetfulness can overlap with anxiety, learning disabilities or even relationship issues, thorough testing is essential. 

Clinicians use a combination of interviews, rating scales and sometimes cognitive tests to build a full picture. These tools help determine whether symptoms are chronic, impairing and consistent with inattentive ADHD , rather than situational or stress-induced. 

Types of Diagnostic Tools 

Clinical interviews and background checks 

A clinician will ask about school history, job performance and personal life to uncover how executive function issues may be affecting focus, memory or organisation. 

Standardised ADHD rating scales 

Tools like the ASRS or Conners’ Rating Scales help quantify symptoms. These self-assessments compare your responses to patterns seen in those with a confirmed ADHD diagnosis. 

Cognitive and behavioural assessments 

In some cases, psychologists may run tasks that test attention span, working memory or response inhibition areas where inattentive ADHD often shows up. 

Once diagnosed, options like medication, therapy, and structured support can significantly improve quality of life. Whether you’re navigating career strain or relationship issues, clarity starts with the right evaluation.
