What Are the Core Symptoms of ADHD Combined Type?

The ADHD symptoms unique to the combined ADHD profile are broken down in this article. You can read the complete guide on ADHD Combined Type  

What is Combined Type of ADHD? 

ADHD combined type is diagnosed when a person meets clinical criteria for both inattentive and hyperactive‑impulsive traits. This means they may experience difficulties with organisation, attention, impulse control, and restlessness. It is common in both children and adults. However, it can sometimes go unnoticed especially in women, who may mask hyperactivity as internal restlessness leading to misdiagnosis. 

Core Symptoms of ADHD Combined Type 

People with combined ADHD symptoms may notice traits from both ends of the spectrum. Here’s how it typically shows up: 

Inattentive Symptoms 

These are the traits traditionally associated with daydreaming, forgetfulness, or being “easily distracted.” 

• Forgetfulness 

• Trouble listening, especially in conversations or instructions 

• Poor organisation skills 

• Frequently losing personal items (e.g. keys, phones, schoolbooks)  

• Avoids tasks that require prolonged mental focus 

• Easily distracted by sounds, movements, or even their own thoughts 

Hyperactive‑Impulsive Symptoms 

This group of ADHD symptoms is more energetic and sometimes disruptive but not always. 

• Fidgeting or squirming in seats 

• Talking excessively, even in inappropriate situations 

• Interrupting others during conversations 

• Struggling to remain seated in meetings, classrooms, or meals 

• Constant restlessness or feeling “on edge” 

• Impulsive behaviour (blurting, risk-taking, interrupting) 

This combination of traits defines the symptoms of ADHD combined type, setting it apart from the more narrowly focused subtypes. 

Why a Diagnosis Can Make a Big Difference 

Many adults with ADHD combined type grow up believing that their difficulties are “just who they are” or the result of personality defects. However, a diagnosis can reframe those traits, providing clarity and access to meaningful support Understanding your ADHD profile allows for a tailored treatment plan that addresses both attention and impulse-related challenges. For both individuals and families, the difference can be life-altering, ranging from time management tools and workplace support to therapy and medication.
