In Australia, ADHD can be formally diagnosed by:
- Psychiatrists: Can diagnose and prescribe ADHD medications (including PBS-subsidised stimulants)
- Paediatricians: For children; can diagnose and prescribe
- Clinical psychologists: Can diagnose but cannot prescribe medication
- General psychologists: Some can assess; diagnostic authority varies by state
Important: Medication Access
If you're considering medication as part of your treatment, you'll need to see a psychiatrist. PBS-subsidised ADHD medications (like Vyvanse, Concerta, Ritalin) require psychiatrist prescription in most states. Some GPs can continue prescriptions initiated by psychiatrists.
What ADHD Assessment Involves
A comprehensive ADHD assessment typically includes:
1. Clinical Interview
Detailed discussion of current symptoms, how they affect daily life, work, and relationships. You'll be asked about attention, organisation, time management, restlessness, and impulsivity.
2. Developmental History
Information about childhood symptoms is essential—ADHD must have been present before age 12 according to DSM-5 criteria. This may involve interviewing parents or reviewing school reports.
3. Standardised Rating Scales
Questionnaires like the ASRS (Adult ADHD Self-Report Scale), Conners' scales, or DIVA (Diagnostic Interview for ADHD in Adults) help quantify symptoms.
4. Ruling Out Other Conditions
The assessor considers whether symptoms might be better explained by anxiety, depression, sleep disorders, or other conditions—or whether these co-occur with ADHD.
5. Cognitive Testing (Sometimes)
Some assessors include neuropsychological testing to examine attention, working memory, and processing speed, though this isn't always required.
The Childhood History Requirement
One challenge with adult ADHD diagnosis is demonstrating that symptoms were present in childhood. This can be difficult when:
- Parents are unavailable or don't recall specific details
- School reports no longer exist
- Symptoms were masked by high intelligence or strong coping strategies
- ADHD wasn't well-understood when you were a child
Experienced adult ADHD assessors understand these challenges. They may use your own recollections, patterns across your life history, or collateral information from siblings or long-term partners. The DSM-5 changed the age-of-onset criterion from 7 to 12, acknowledging that symptoms may not become apparent until demands exceed someone's capacity.
