This guide is for general information only and is not medical advice. Pillr helps with medication reminders, dose tracking, and routine notes, but it does not diagnose, treat, prevent, or cure ADHD. Speak with your doctor, psychiatrist, pharmacist, or prescribing clinician about medication timing, missed doses, side effects, or treatment decisions.
In Australia, prescription medicines should be used only as prescribed by an authorised healthcare professional.
The short answer: diagnosis is a full assessment
An adult ADHD assessment brings together a clinical interview, developmental and health history, current daily impact, and information from more than one part of life. A screening questionnaire may be included, but it is only one source of information.
The National Institute of Mental Health explains that adult assessment looks at current symptoms, childhood behaviour, school experiences, mental and physical health, and whether another condition could better explain the difficulties.
NICE guidance says diagnosis should be made by an appropriately qualified healthcare professional with training and expertise in ADHD, using a full clinical and psychosocial assessment rather than a rating scale alone.
What an adult ADHD assessment may cover
The exact pathway and professional involved depend on where you live. A thorough assessment commonly explores:
- Current patterns: attention, restlessness, impulsivity, organisation, time, memory, and follow-through.
- Daily impact: what happens at work, study, home, in relationships, or while managing everyday tasks.
- Childhood history: whether similar patterns were present earlier in life.
- More than one setting: whether the difficulties appear across different parts of life.
- Health context: mental health, physical health, sleep, substance use, medications, and other factors that may need consideration.
- Other perspectives: past reports or input from someone who knows you well, when useful and available.
The Australian evidence-based ADHD guideline describes clinical interviews, questionnaires, multiple informants, developmental history, functioning, and medical assessment as parts of a high-quality diagnostic process. It also notes that neuropsychological testing is not required for every ADHD diagnosis, although extra assessment may help when other conditions or learning needs are unclear.
Use a one-page assessment prep sheet
You do not need a perfect life story. A few clear examples can make the first conversation easier.
| What to note | Plain example |
|---|---|
| The pattern | "I lose track of spoken instructions unless I write them down." |
| Where it happens | "At work meetings and while organising tasks at home." |
| How often | "Several times most weeks, especially during busy periods." |
| The impact | "I miss follow-up steps and spend extra time checking my work." |
| Earlier examples | "School reports often mentioned unfinished work, if those records are available." |
| Your question | "What else could explain this pattern, and what does the assessment involve?" |
Also bring a current medication list, relevant health information, previous reports you already have, and the assessor's requested forms. School reports or input from another person may help, but requirements vary, so ask the service what it needs before the appointment.
What screening tools can and cannot do
A questionnaire can help organise symptoms and show which areas deserve discussion. It cannot confirm ADHD by itself, rule out other explanations, or replace clinical judgement.
If an online checklist makes you concerned, save the result as a conversation starter and speak with a qualified healthcare professional. Avoid treating a score as a diagnosis.
Where Pillr fits
Pillr is an ADHD medication reminder and dose tracking app available on iPhone and iPad. If medication later becomes part of a clinician-led plan, Pillr can help you keep reminders, taken or skipped dose records, routine notes, and medication history together.
Pillr does not screen for or diagnose ADHD, choose treatment, interpret symptoms, change medication timing, or replace professional care.
