Attention-Deficit/Hyperactivity Disorder (ADHD) is not a one-size-fits-all diagnosis. In fact, it presents in three distinct types, each with its own symptom patterns and challenges. Understanding which type of ADHD you or your child has is a crucial first step in receiving the right treatment and support.
At Serene Minds Mental Health PLLC, based in Durham, North Carolina, we specialize in comprehensive ADHD treatment tailored to individual needs. Whether you are dealing with inattention, hyperactivity, impulsivity, or a mix of all three, we’re here to help.
What Is ADHD?
ADHD is a neurodevelopmental disorder that affects people of all ages. Characterized by persistent patterns of inattention, hyperactivity, and impulsivity, ADHD impacts daily functioning and overall quality of life. According to the Centers for Disease Control and Prevention (CDC), about 6 million children aged 3–17 in the U.S. have been diagnosed with ADHD, and symptoms often continue into adulthood.
Although ADHD is often associated with disruptive behavior, that’s only one part of the picture. There are different types of ADHD, each presenting unique symptoms and requiring distinct approaches to treatment.

Types of ADHD
1. Predominantly Inattentive Type
People with predominantly inattentive ADHD struggle primarily with concentration and focus. This type was once referred to as ADD (Attention Deficit Disorder) and is more commonly underdiagnosed—especially in girls.
Symptoms:
Difficulty staying focused on tasks or conversations
Trouble finishing assignments or chores
Frequently losing items like keys, school supplies, or phones
Appearing not to listen when spoken to
Struggling to follow through on instructions
Easily distracted by external stimuli or unrelated thoughts
Who it affects: This type is commonly overlooked in children who are not disruptive, particularly girls, who may appear quiet, dreamy, or introverted in the classroom. These children often fall through the cracks, as their symptoms are internalized rather than outwardly disruptive.
Treatment Approach: For individuals with inattentive ADHD, the treatment focus is often on improving organizational skills, time management, and concentration. Behavioral therapy and medication (such as stimulants or non-stimulants) are commonly used. Educational interventions and mindfulness strategies can also be very helpful.
2. Predominantly Hyperactive-Impulsive Type
This type is more visible and frequently diagnosed in early childhood, especially in boys. It involves hyperactive and impulsive behaviors, often without the prominent inattention found in other types.
Symptoms:
Fidgeting, tapping, or squirming in seat
Talking excessively and blurting out answers
Difficulty waiting for turns in games or conversations
Interrupting others frequently
Restlessness and constant movement
Who it affects: Hyperactive-impulsive ADHD is commonly identified in young boys who are more likely to display physical symptoms of restlessness and impulsivity. These symptoms can lead to classroom disruptions and behavioral challenges.
Treatment Approach: For hyperactive-impulsive ADHD, behavioral interventions and parent training can be highly effective, especially when combined with medication. Techniques that involve improving self-regulation and teaching coping mechanisms are crucial.
3. Combined Type (Inattentive and Hyperactive-Impulsive)
This is the most common type of ADHD and includes symptoms of both inattention and hyperactivity/impulsivity.
Symptoms:
Difficulty focusing on tasks
Easily distracted and forgetful
Impulsiveness and interrupting others
Trouble sitting still or engaging in quiet activities
Disorganization and poor time management
Who it affects: Anyone can experience combined-type ADHD, and it often becomes more evident during school-age years when demands for concentration and self-regulation increase. Adults with this type may struggle with relationships, work productivity, and managing responsibilities.
Treatment Approach: Because this type involves a combination of symptoms, a multimodal treatment plan is typically necessary. At Serene Minds, we offer comprehensive ADHD treatment in North Carolina that includes medication management, lifestyle support, behavioral therapy, and mindfulness-based interventions.
Why an Accurate Diagnosis Matters
Understanding the type of ADHD is essential for effective treatment planning. The presentation of symptoms may change over time, which is why ongoing evaluation and flexibility in treatment are key.
An accurate diagnosis helps:
Tailor medication choices and dosages
Customize therapeutic interventions
Educate parents, teachers, and caregivers
Provide individuals with self-awareness and coping tools
