Clinically diagnosing ADHD Combined Type involves identifying a persistent pattern of both inattentive and hyperactive-impulsive ADHD symptoms. The process is detailed and multi-layered, aiming to understand how these traits disrupt daily life and impair executive function. Diagnosis typically includes structured interviews, behavioural questionnaires, and observations across different settings at home, school, or work. It also requires ruling out other conditions that may resemble ADHD such as anxiety, trauma, or mood disorders.

What Clinicians Assess

A robust clinical evaluation draws from multiple sources to build a full picture. Here’s what practitioners look for during assessment:

Core symptom patterns

A mix of inattention (e.g. losing focus mid-task) and hyperactivity-impulsivity (e.g. interrupting or acting without thinking) must be present for at least six months and across more than one environment.

Executive function challenges

Difficulty with planning, organising, or managing time signals deeper disruptions in how the brain processes and acts on information. These difficulties are central to the ADHD Combined Type.

Emotional regulation issues

Outbursts, frustration, or mood shifts often accompany ADHD, but are not always discussed. Assessing these can shape more responsive support groups and therapy options.

A clinical ADHD diagnosis opens the door to targeted treatment, often a combination of medication, behavioural support, and long-term therapies that include CBT and structured coaching.
