A person with an ADHD combined type diagnosis may experience anxiety while preparing for the future. While you may be familiar with the term ADHD, you may be less so when it is paired with the term combined. If so, you may be interested in learning more about the characteristics that distinguish the combined ADHD type from other types of ADHD.

This article examines the inattentive, hyperactive, and impulsive symptoms of combined ADHD presentation, its causes, and available ADHD treatments.

Key Takeaways

Combined type ADHD  is a mental condition with symptoms of both inattention and hyperactivity or impulsivity. This article digs further into combined type ADHD. We examine probable causes, common symptoms, and accessible treatment choices, such as medication, behavioral therapy, and lifestyle adjustments like exercise and food modifications.

What Is ADHD Combined Type?

Combined ADHD type is a form of ADHD that is characterized by symptoms of both inattention and hyperactivity/impulsivity.[1] According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, this subtype of ADHD is one of three distinct types of the condition. People with this diagnosis have six or more symptoms of both inattentive and hyperactive/impulsive behavior.

Symptoms Of ADHD Combined Type 

Inattention, hyperactivity,[2] and impulsivity symptoms often characterize combined type ADHD, which can affect many areas of life. If you live with ADHD combined type, you may experience symptoms such as 

  • Trouble focusing on one thing for long periods of time without getting sidetracked.
  • Difficulty sitting still,[2] waiting in line, or focusing on quiet activities.
  • Trouble controlling your emotions and behaviors; having an anxiety disorder or a mood disorder.
  • Poor time management and organization.
  • Feeling overwhelmed and finding it difficult to finish tasks or difficulty waiting their turn.

Commitment may also be challenging for people living with ADHD because of the difficulties they face in both professional and social situations. Of course, symptoms will vary between individuals, so it’s important to discuss your experiences with your doctor. 

Causes Of ADHD Combined Type

Despite extensive research, the causes of combined type ADHD remain unclear. A person’s vulnerability to developing combined ADHD may be influenced by various factors, including genes, environmental factors, and possibly nutrition. 


A family history of the disorder significantly increases the likelihood of developing any form of ADHD. Studies have shown that genetics can play a significant role in the onset of ADHD.[3] Genetics can explain most of the variation in ADHD characteristics with high heritability. 

Use Of Alcohol Or Cigarettes During Pregnancy

Studies suggests[4] that expecting moms who smoke have a higher chance of having a child with ADHD.

Premature Birth

Evidence indicates that children born before their due date have an increased chance of acquiring combined ADHD later in life.

Traumatic Brain Injury

Some children with catastrophic brain injuries may be diagnosed with combined ADHD later in life. A study that examined the prevalence of ADHD in children with a history of traumatic brain injuries[5] found that 62% of the study participants developed ADHD, compared to 15% of the control group who did not have a traumatic brain injury.

Exposure To Environmental Toxins

Environmental pollutants have been associated with ADHD,[6] especially ADHD combined type ICD-10, although the connection is complicated and poorly understood.  Environmental toxins may have different effects on different people and ADHD subtypes, such as ADHD Inattentive Type in Adults. Toxins in the environment may have a role in the development of ADHD, but further study is required to determine the strength of this relationship and how it affects various age groups and ADHD subtypes.

ADHD Combined Type Treatments 

Effective treatment for combined ADHD typically requires a multifaceted approach incorporating medication and non-medication methods. It’s crucial to work closely with a medical practitioner to develop a personalized treatment plan and to be flexible as you experiment with different approaches.

Options for treating combined ADHD symptoms include:

ADHD Medications

Stimulant medications may help patients with combined ADHD manage inattentive ADHD and alleviate hyperactivity and impulsivity symptoms. Doctors may also recommend non-stimulant medications. Even though they work more slowly, these medications can effectively reduce the signs and symptoms of ADHD in some patients. Additionally, your doctor may prescribe a combination[7] of the two if they feel it is necessary.

Behavioral Therapy

People with combined-type ADHD, especially children, may improve their academic and social functioning via behavior therapy. Behavioral therapy aims to encourage positive actions and discourage actions that work against your goals. Both you and your child will learn practical strategies for rewarding good behavior. Behavioral therapy[8] may be used by a parent, teacher, or therapist to help a child form positive routines.

Social Skills Therapy

This approach teaches people how to read and respond appropriately to social cues. Social skills training may enhance ADHD treatment if it helps individuals overcome hyperactive, impulsive symptoms. This training aims to improve social interaction, language competency, and understanding of nonverbal clues. This may assist individuals with ADHD Combined Type better their social interactions,[9] forming new connections, and coping more successfully with social situations. 

Family Therapy

Family counseling can be helpful when navigating a new ADHD diagnosis. Some evidence suggests that family therapy can assist fellow household members in learning how to better manage the effects.[10] This also can improve communication and connection among families with adult ADHD or a family situation with both adult and child ADHD.

Organizational Skills Training

This ADHD treatment strategy[11] may assist a person in overcoming challenges of forgetfulness and disorganization. Treatment for organizational skills inadequacies focuses on prioritizing, work delegation, and general efficiency. It includes techniques for staying organized, creating routines, managing duties, and establishing priorities. By strengthening their ability to concentrate and accomplish activities, persons with combined ADHD type may become more confident in themselves, more productive at work, and happier in general.

Cognitive Behavioral Therapy

Cognitive Behavioral Therapy is often used to treat anxiety or mood disorders by providing individuals with tools to manage their emotions and behaviors. While this therapy might be helpful for individuals living with combined ADHD,[12] further research is needed.

Talk Therapy

Standard talk therapy can also support your ADHD management efforts. Your therapist can help you recognize your challenges and work with you to develop more effective coping strategies. 

Other Types Of ADHD

There are two additional types of ADHD. These are:

Hyperactive And Impulsive Type ADHD

Hyperactive and impulsive type ADHD is typically diagnosed when an individual has exhibited five or more symptoms for at least six months. These symptoms can include[13] fidgeting, inability to sit still, difficulty playing quietly, interrupting others, and talking excessively, among others. This kind of ADHD appears more prevalent in younger children and men.

Inattentive Type ADHD

Inattentive type ADHD is typically diagnosed when inattentive symptoms such as poor attention to detail, forgetfulness in daily activities, poor listening skills, and lack of follow-through. Like hyperactive and impulsive ADHD, a diagnosis requires the presence of at least five symptoms over at least six months. Other symptoms include avoiding tasks that require mental effort, losing items necessary for essential tasks, and getting distracted easily. 

The Bottom Line

Combined type ADHD includes symptoms of hyperactive and impulsive, and inattentive ADHD. The inability to concentrate on a single activity and the need to always be on the move are typically present in people with combined-type ADHD.  

Like other types of ADHD, combined type ADHD may vary in severity, and your treatment choices may include medication and psychotherapy. Medications are used to treat ADHD symptoms, while talk and behavioral therapy can help individuals develop tools to manage symptoms. Training and online therapy can help parents learn appropriate communication methods to use with their children who have been diagnosed with combined-type ADHD. 

Schools can also be an excellent resource for families learning to navigate a new ADHD diagnosis. And, of course, if you have questions about ADHD and its effects on your life, it’s best to discuss them with your doctor.
