What should you know about types of ADHD in adults?

Inattentive symptoms may look like missed details, unfinished tasks, poor time management, losing items, or difficulty prioritising. Hyperactive-impulsive symptoms may be felt as inner restlessness, excessive talking, interrupting, impatience, or rapid decisions rather than obvious physical activity. Combined presentation includes both patterns. Adults may have developed coping systems that hide symptoms in some settings while work, parenting, finances, or relationships expose the strain. [Difficulty Concentrating](/symptoms/difficulty-concentrating/), [Feeling Anxious](/symptoms/feeling-anxious/), and [Irritability](/symptoms/irritability/) are not specific to ADHD and should be assessed in context.

A specialist assessment usually explores current difficulties, childhood history, functioning across settings, sleep, mood, substance use, medical conditions, and medicines. Bring examples of missed deadlines, impulsive choices, or disorganisation, and ask a trusted person for observations if appropriate. Support may involve skills-based strategies, workplace adjustments, psychological care, and prescribed medicine. A [Mental Health Assessment](/treatments/consultations-and-assessment/mental-health-assessment/) can distinguish ADHD from problems that need a different treatment.

Seek an assessment when symptoms repeatedly affect employment, study, driving, relationships, money management, or self-care. Get urgent help if impulsivity creates immediate danger, or if you have thoughts of self-harm, severe agitation, or confusion. New concentration or behaviour changes in adulthood should be medically reviewed rather than automatically attributed to ADHD.

Ask how childhood evidence is considered, which conditions can resemble ADHD, whether medication is suitable, and what practical support could reduce difficulties before assessment is complete.
