Key facts

- It is not caused by bad parenting or too much sugar.
- With the right support, people with ADHD can lead successful and fulfilling lives.
Yes, ADHD is one of the most common neurodevelopmental conditions in children, and it is also increasingly recognized in adults.
ADHD affects people of all ages, genders, and backgrounds. It is often diagnosed in childhood, but many adults are diagnosed later in life.

When to see a doctor
See a doctor urgently if:
- If symptoms are causing serious problems at school, work, or home, or if you feel unsafe or overwhelmed.
Book a routine appointment if:
- If you or your child have ongoing difficulties with focus, impulsivity, or hyperactivity that affect daily life, talk to a doctor or mental health professional.
Diagnosis
A specialist, like a psychiatrist or a clinical psychologist, will assess your symptoms through interviews, questionnaires, and sometimes talking to family or teachers. There is no single test for ADHD.
Tests that may be done
- Medical history and symptom checklists
- Behavior rating scales completed by you, your family, or teachers
- Sometimes cognitive tests or computer tasks to measure attention and impulse control
What to expect at your appointment
The evaluation may take a few visits. The specialist will rule out other conditions that could explain the symptoms. Diagnosis is based on patterns of behavior over time, not one single event.
Treatment
Treatment for ADHD usually involves a combination of behavioral strategies, education, support, and sometimes medication. A healthcare provider will work with you to create a personalized plan.
Self-care at home
- Create a daily routine and use reminders like calendars or phone alarms.
- Break tasks into small, manageable steps.
- Practice mindfulness or relaxation techniques to help with focus and impulse control.
- Get enough sleep, eat regular meals, and stay physically active.
Medical treatments
Medications can help some people with ADHD by improving focus and reducing impulsivity. These are prescribed by a doctor and come in different types, such as stimulants and non-stimulants. The choice depends on individual needs and health.
When is surgery considered?
Surgery is not used to treat ADHD.
Living with this condition
Managing ADHD can take practice, but many people develop strategies that work for them. Key tools include structure, reminders, and support from family, friends, or support groups.
Lifestyle tips
- Stick to a consistent sleep schedule.
- Use visual planners or apps to organize tasks.
- Take breaks during long tasks to reset your focus.
- Find physical activities you enjoy to help channel extra energy.
Diet and exercise
A balanced diet with regular meals may help stabilize energy and mood. Exercise can improve focus and reduce restlessness – aim for at least 30 minutes of activity most days.
Mental health and emotional wellbeing
Living with ADHD can sometimes lead to frustration, anxiety, or low self-esteem. It is important to address these feelings and seek support from a mental health professional if needed.
Prevention
There is no known way to prevent ADHD, but early recognition and support can help reduce its impact on daily life.
Vaccines
Vaccines do not cause ADHD. Staying up-to-date on recommended vaccines is safe and important for overall health.
Screening programmes
There is no routine screening test for ADHD. If you have concerns, talk to your doctor about an evaluation.
Complications
If left untreated
- Difficulty in school or work, leading to underachievement
- Strained relationships with family or friends
- Increased risk of accidents due to impulsivity
- Higher likelihood of developing anxiety or depression
Long-term outlook
With the right support, treatment, and lifestyle changes, most people with ADHD can manage their symptoms and live full, productive lives. Many successful people have ADHD.
