Differences between Combined-Type and Hyperactive/Impulsive ADHD: A Comprehensive Guide

Attention Deficit Hyperactivity Disorder (ADHD) is a neurobehavioral disorder characterized by a range of symptoms. It is commonly classified into three types: predominantly inattentive ADHD, predominantly hyperactive/impulsive ADHD, and combined type ADHD. This article will explore the differences between the predominantly hyperactive/impulsive and combined types of ADHD, highlighting the key symptoms and characteristics of each.

Understanding ADHD

ADHD is now categorized into three main subtypes in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). These subtypes are distinguished by specific sets of symptoms. To simplify the diagnosis and treatment process, these symptoms are grouped into three categories: inattention, hyperactivity, and lack of impulse control. Each subtype is defined by the presence or absence of symptoms from these categories.

Predominantly Inattentive ADHD

Predominantly inattentive ADHD, previously known as attention deficit disorder (ADD), is characterized by difficulties in regulating attention. Individuals with this type of ADHD struggle with focusing, completing tasks, and following instructions. Unlike the predominantly hyperactive/impulsive type, inattentive ADHD is less disruptive in a classroom setting. It is more commonly observed in girls with ADHD due to the less disruptive nature of the symptoms.

Predominantly Hyperactive-Impulsive ADHD

Predominantly hyperactive/impulsive ADHD is the opposite of inattentive ADHD, focusing on impulsivity and hyperactivity. People with this type of ADHD exhibit behavior such as fidgeting, interrupting others, and an inability to wait their turn. While inattention is less of a concern, those with predominantly hyperactive-impulsive ADHD may still struggle with focusing on tasks.

Combined-Type ADHD

Combined-type ADHD is a combination of inattentive and hyperactive/impulsive behaviors. It encompasses all the characteristics of both the inattentive and hyperactive/impulsive types. The symptoms of combined-type ADHD include restlessness, being talkative, careless mistakes, missing details, and impulsive actions. These behaviors often make it challenging to maintain focus and may lead to difficulties in social and academic settings.

Personal Experience with Combined-Type ADHD

Individuals with combined-type ADHD often have a mix of symptoms from the inattentive and hyperactive/impulsive subtypes. Based on my personal experience, I was assessed on inattention, hyperactivity, impulsivity, and sluggish cognitive tempo. My scores were significantly high for the first three but not for sluggish cognitive tempo.

Hyperactive Symptoms

Hyperactive symptoms in combined-type ADHD might include:

Restlessness Excessive talking Difficulty sitting still, even in situations where it is inappropriate

Inattentive Symptoms

Inattention symptoms in combined-type ADHD can include:

Careless mistakes or missing details Difficulty focusing on tasks or following through with them Difficulty staying organized

Impulsive Behaviors

Impulsive behaviors in combined-type ADHD may manifest as:

Hasty and unplanned actions interrupting others without considering the consequences Frequent changes in activity or interest without completing one task

Conclusion

Understanding the differences between combined-type ADHD and predominantly hyperactive/impulsive ADHD is crucial for effective diagnosis and treatment. Recognizing these differences can help individuals, families, and healthcare providers address the unique needs of those living with ADHD.
