DSM-5 describes three presentations of ADHD: predominantly inattentive, predominantly hyperactive-impulsive and combined. This guide explains each type, how they differ and what they mean for support.
DSM-5 categorises ADHD into three presentations based on which symptom clusters predominate. The combined presentation involves significant inattention and significant hyperactivity-impulsivity. The predominantly inattentive presentation involves significant inattention without significant hyperactivity-impulsivity. The predominantly hyperactive-impulsive presentation involves significant hyperactivity-impulsivity without the inattentive component being as prominent. Understanding which presentation is present helps guide assessment, support and treatment decisions.
SENDhelp places specialist SEN teachers, teaching assistants and support staff in schools and provisions across North London, Bedfordshire, Buckinghamshire and Hertfordshire. If your school needs staff experienced with ADHD, we can help.
The combined presentation of ADHD involves significant symptoms in both the inattentive domain and the hyperactive-impulsive domain. This is the most commonly diagnosed presentation in children and in many studies in adults too. A person with the combined presentation experiences difficulties with attention regulation, impulse control and hyperactivity simultaneously, and the interaction between these difficulty areas can compound their functional impact.
The predominantly inattentive presentation of ADHD involves significant inattention without prominent hyperactivity or impulsivity. This presentation is characterised by difficulty sustaining attention, easy distractibility, forgetfulness, losing things, difficulty organising tasks, failing to complete tasks and careless mistakes. This presentation is more commonly missed in assessment, particularly in girls and adults, because the absence of overt hyperactivity makes the condition less visible to others.
The predominantly hyperactive-impulsive presentation involves significant hyperactivity and impulsivity without the inattentive component being as prominent. This presentation is more common in younger children. Symptoms include fidgeting, difficulty staying seated, running or climbing excessively in situations where it is inappropriate, talking excessively, blurting out answers, difficulty waiting for a turn and interrupting or intruding on others. This presentation may evolve into the combined presentation as inattentive symptoms become more apparent with age.
ADHD presentations are not fixed. A person’s presentation may change over the lifespan as symptom profiles evolve. Hyperactivity tends to become less overtly physical in adolescence and adulthood, often presenting as internal restlessness rather than visible movement. As a result, a child who had combined presentation ADHD may present more like the predominantly inattentive type in adulthood. DSM-5 allows for specifiers to change between assessments as the symptom profile changes.
The combined presentation is the most commonly diagnosed across most age groups. The predominantly inattentive presentation becomes proportionally more common in the assessed population as people age, reflecting both the decline in hyperactivity and the increased recognition of inattentive ADHD in adults. The predominantly hyperactive-impulsive presentation is most common in younger children.
All three presentations of ADHD respond to broadly similar treatment approaches. Stimulant medications are effective across all presentations, though the balance of which symptoms are most prominent may influence clinical decisions about dosing and timing. Behavioural interventions, coaching, environmental adjustments and educational support are effective across all presentations. Treatment is tailored to the individual’s specific symptom profile and functional needs rather than to the presentation type alone.

DSM-5 describes three presentations of ADHD. The combined presentation involves significant inattention and significant hyperactivity-impulsivity. The predominantly inattentive presentation involves significant inattention without prominent hyperactivity. The predominantly hyperactive-impulsive presentation involves significant hyperactivity and impulsivity without the inattentive component being as prominent.
The combined presentation is the most commonly diagnosed type across most age groups. The predominantly inattentive presentation is more commonly identified in adolescents and adults, partly because hyperactivity tends to become less visible with age. The predominantly hyperactive-impulsive presentation is most commonly seen in younger children.
Yes. ADHD presentations can change over the lifespan. Hyperactivity tends to reduce with age, which can mean that someone who had combined presentation ADHD in childhood presents more like predominantly inattentive ADHD in adulthood. DSM-5 allows for the presentation specifier to be updated between assessments to reflect changes in the symptom profile.
