When to see a doctor
See a doctor urgently if:
- If you have thoughts of harming yourself or feel like you can't cope
- If you experience concerning side effects from medication (e.g., chest pain, severe mood changes)
Book a routine appointment if:
- If ADHD symptoms are making it hard to keep up at work, school, or in relationships
- If you wonder whether you might have undiagnosed ADHD and want an assessment
Diagnosis
There is no single test for ADHD. A diagnosis is made by a qualified healthcare professional (often a psychiatrist or psychologist) based on a detailed conversation about your symptoms, your childhood history, and how the condition affects your daily life.
Tests that may be done
- Standardised questionnaires or rating scales about your symptoms
- A review of your personal and family medical history
- Sometimes a cognitive test or computer-based attention test
What to expect at your appointment
The assessment usually takes one to two sessions. The professional will ask about your difficulties, your school and work performance, and any other conditions that might explain symptoms. They may also ask a partner or close family member for their perspective.
Treatment
Treatment for adult ADHD usually combines medication, talking therapies, and practical strategies to manage everyday challenges. The goal is to help you manage symptoms so you can function better at work, home, and in relationships.
Self-care at home
- Use planners, alarms, and apps to keep track of tasks and appointments
- Break large tasks into small, manageable steps
- Minimise distractions by creating a quiet, organised workspace
- Practice mindfulness or relaxation techniques to help calm your mind
- Set a consistent daily routine for sleep, meals, and work
Medical treatments
Medication can help balance brain chemicals that affect attention and impulse control. There are two main types: stimulant medications (which work quickly) and non‑stimulant medications (which may be used if stimulants are not suitable or cause side effects). Your doctor will work with you to find the right approach, and you should never change or stop medication without medical advice.
Living with this condition
Living with adult ADHD means learning to work with your brain's natural wiring. Creating structure – like a predictable morning routine or using checklists – can make a big difference. It's also helpful to be kind to yourself and ask for help when you need it.
Lifestyle tips
- Establish consistent sleep habits – aim for 7–9 hours per night
- Set small, daily goals and celebrate when you meet them
- Use visual reminders like sticky notes or whiteboards
- Build in regular movement breaks to release restless energy
- Limit caffeine and alcohol, as they can worsen symptoms
Diet and exercise
A balanced diet with plenty of fruits, vegetables, and protein supports brain health. Regular exercise – even a 20‑minute walk – can boost focus and mood. Some people find that reducing sugar or processed foods helps, but there is no special 'ADHD diet' that works for everyone.
Mental health and emotional wellbeing
ADHD can lead to feelings of frustration, low self‑esteem, or anxiety, especially if you've faced criticism in the past. Talking to a therapist or joining a support group can help you work through these feelings and build confidence.
Prevention
ADHD cannot be prevented, but early recognition and management can reduce its impact on daily life. A healthy lifestyle and good support systems also help.
Complications
If left untreated
- Struggles at work or school, including missed deadlines or job loss
- Relationship difficulties due to forgetfulness or impulsive behaviour
- Increased risk of anxiety, depression, or low self‑worth
- Higher chances of substance misuse (e.g., alcohol, cannabis)
Long-term outlook
The outlook for adults with ADHD is very positive when they receive the right support. With treatment, self‑help strategies, and understanding from others, many people with ADHD build successful careers, loving relationships, and fulfilling lives.
