What ADHD Combined Type Actually Looks Like

What are the main types of ADHD?

ADHD has 3 main types. They are ‘predominantly inattentive’, ‘predominantly hyperactive-impulsive’, and ‘combined’. As the name suggests, the ‘combined’ type of ADHD presents as a mixture of symptoms from the other 2 types of the condition.

Here’s an outline of common ADHD symptoms for the hyperactive-impulsive and inattentive types, which may also be present in the combined type.

How does combined type ADHD present?

Because combined ADHD is a mixture of the inattentive and hyperactive-impulsive types, there are many ways it can present, since there are a variety of symptoms associated with each type that could occur in someone with combined ADHD.

Because of this, some people might find it hard to identify that they have ADHD, or may have difficulty achieving a diagnosis, because their symptoms don’t fully align with one of the hyperactive-impulsive or inattentive types of ADHD. The interplay of hyperactive-impulsive and inattentive symptoms can also bring unique challenges. For example, the inattentive difficulty with focus may be exacerbated by the hyperactive-impulsive symptom of feeling restless.

Diagnosing combined type ADHD

The diagnostic criteria in the Diagnostic and Statistic Manual (DSM) states that for children 17 and under, at least 6 symptoms of both inattentive and hyperactive-impulsive ADHD should be present. For those aged over 17, 5 symptoms of each type are required. The inattentive and hyperactive-impulsive symptoms should also be balanced, so that the symptoms from one type do not clearly dominate over the other.
