Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition characterised by persistent patterns of inattention, hyperactivity and impulsivity that interfere with daily functioning. It is one of the most common conditions of childhood, and for the majority of people it continues into adulthood, although it often looks different as life changes.

ADHD is not a failure of willpower, intelligence or character. It reflects genuine differences in how the brain regulates attention, activity and impulses. Without recognition and support, those differences can take a heavy toll: underachievement despite real ability, strained relationships, low self-esteem, and exhaustion from constantly compensating.

How ADHD presents

ADHD generally presents in three broad patterns. Firstly, predominantly inattentive presentations involve difficulty sustaining attention, distractibility, forgetfulness, losing things, trouble organising tasks, and careless mistakes; this pattern is easily missed, particularly in girls and women. Secondly, predominantly hyperactive-impulsive presentations involve restlessness, difficulty sitting still, talking excessively, interrupting, and acting before thinking. Thirdly, combined presentations can include features of both.

In adults, hyperactivity often becomes an internal restlessness rather than visible fidgeting, while difficulties with organisation, time management, emotional regulation, follow-through and working memory frequently become the most impairing features. Importantly, each presentation is individual and a personalised approach is required.

Diagnosis

There is no single test for ADHD. Diagnosis requires a comprehensive assessment by an experienced clinician, covering current symptoms and their impact, a developmental history reaching back to childhood, information from people who know you well, and careful screening for the many conditions that can mimic or accompany ADHD, including anxiety, depression, sleep disorders and learning difficulties. Both psychiatrists and psychologists at Mind Connections provide this assessment for adults; see our ADHD Assessment and Treatment service page for the full process.

Treatment

ADHD responds well to treatment. Medication remains the most effective single intervention for core symptoms, and works for the substantial majority of people when properly tailored and monitored. Psychological strategies, coaching, environmental adjustments at school or work, exercise, and education about the condition all add meaningful benefit. Treatment plans at Mind Connections are individual, reviewed regularly, and built around what matters most in your life.
