There are three recognised types of ADHD, and it can be confusing to understand which type applies to you or your child. This brief comparison on combined ADHD vs hyperactive-impulsive ADHD highlights the need for clarity and provides guidance for further exploration. If you would like a full breakdown on each subtype, see our dedicated articles on Combined and Hyperactive-Impulsive ADHD
What Is Combined ADHD?
Combined ADHD involves both inattentive and hyperactive-impulsive traits in roughly equal measure. In both adults and children, it is the most frequently diagnosed subtype. It may involve challenges with task organisation and tendencies such as fidgeting or interrupting others. See our full article on Combined ADHD for a more comprehensive overview.
What Is Hyperactive-Impulsive ADHD?
Hyperactive-impulsive ADHD is dominated by strong symptoms of hyperactivity and impulsivity, with little to no inattentive traits. Children who are constantly active or struggle to wait their turn are more likely to be diagnosed with this type. See our comprehensive guide on Hyperactive-Impulsive ADHD for a detailed examination of this subtype.
