What should you know about adult ADHD?

It can affect planning, time awareness, working memory, emotional control, relationships and performance at work or in education. Diagnosis is based on a detailed clinical assessment rather than a single questionnaire, brain scan or blood test.

Inattention may show up as losing essential items, missing details, drifting away during conversations, postponing demanding tasks or struggling to finish what was started. Hyperactivity in an adult may feel like inner restlessness rather than obvious running about, while impulsivity can involve interrupting, rapid decisions or difficulty waiting.

Symptoms associated with ADHD begin earlier in life, although changing demands can make the difficulty clearer in adulthood. Sleep problems, anxiety, depression, substance use, medication effects and some physical health conditions can produce overlapping problems, which is why careful assessment matters.

Record concrete examples from work, home, education and relationships, along with any childhood reports or observations from someone who knows you well. During assessment, expect questions about development, sleep, mood, anxiety, physical health, medicines and substance use.

Management can combine education about ADHD, structured routines, environmental changes, coaching or psychological therapy, and medication when clinically suitable. Using one calendar, visible reminders, short task lists, reduced distractions and planned breaks can make responsibilities easier to start and track. Medication requires individual prescribing and monitoring for benefit, side effects, sleep, appetite, pulse and blood pressure.

Arrange a clinical assessment when attention, organisation, restlessness or impulsive behaviour repeatedly disrupts work, education, finances, driving, relationships or self-care. New concentration problems that appeared suddenly deserve assessment for another cause rather than being assumed to be ADHD.

Seek urgent help for thoughts of suicide or self-harm, an inability to stay safe, severe agitation, hallucinations, extreme confusion, chest pain or fainting. If these symptoms occur while taking prescribed medication, follow emergency advice and tell the treating clinician what was taken.

Useful questions include which features support the diagnosis, what alternative explanations have been considered and how progress will be measured. Discuss therapy and medication choices, possible side effects, interactions with existing medicines, driving or work concerns, and the plan for follow-up.
