Some people feel frustrated when they hear that ADD and ADHD are the same. They feel that the “H,” which stands for hyperactivity, doesn’t accurately describe them or their child. Understanding the evolution of the changes in the name can help.

A Brief Timeline of the Changing Name of ADHD

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is published by the American Psychiatric Association. It’s the standard guideline that doctors, mental health professionals, and clinicians use when they’re assessing and diagnosing ADHD and other mental health issues. Each new update and revision of the DSM is eagerly anticipated, as it can mean a big or small change in what each condition is called, and in the criteria for diagnosing them, including ADHD. 

1980

The third edition of the DSM (DSM-III) was released and the official name for the condition became attention-deficit disorder (ADD). At this time, hyperactivity was not considered to be a frequent symptom. Two subtypes of ADD were identified:

ADD with hyperactivityADD without hyperactivity

1987

A revised version of the DSM-III was released. The official name became attention-deficit hyperactivity disorder (ADHD). This meant that hyperactivity was considered to be an important feature of ADHD.

1994 

The DSM-IV was published, with a slight grammar change in the name. The official name was now attention-deficit/hyperactivity disorder. The slash between attention-deficit and hyperactivity disorder indicated something meaningful. You could have either or both subtypes. You didn’t need to be hyperactive to be diagnosed with ADHD. The three subtypes were called:

Attention-deficit/hyperactivity disorder, combined type Attention-deficit/hyperactivity disorder, predominantly inattentive typeAttention-deficit/hyperactivity disorder, predominantly hyperactive-impulsive type        

2013

The fifth edition of the DSM was released (DSM-5). The three subtypes of ADHD remain the same, but now they’re called presentations instead of subtypes. They include: 

Attention-deficit/hyperactivity disorder, combined presentation Attention-deficit/hyperactivity disorder, predominantly inattentive presentation   Attention-deficit/hyperactivity disorder, predominantly hyperactive-impulsive presentation.            

Using the Term ADD

You can still use the term ADD and people will almost certainly understand you. Many doctors, clinicians, and writers use ADD to mean inattentiveness and use ADHD to describe someone with hyperactivity. Some people use ADD and ADHD interchangeably. However, if you can make the mental switch from ADD to ADHD, it will help avoid potential confusion and keep you up-to-date with the most current terms.

ADD vs. ADHD in Children

Many people with inattentive ADHD feel that using hyperactivity in the name of their condition misrepresents their struggles. However, recognizing the key differences in the three subtypes of ADHD can be helpful. ADHD is most frequently diagnosed in childhood, but it is important to recognize that it can and often does persist into adulthood. The traits associated with the subtypes can present somewhat differently in children than adults.

Primarily Inattentive ADHD

This subtype involves inattentiveness, lack of focus, and disorganization. This pattern of characteristics is what people often mean when they use the term ADD. Common traits that children with this form of ADHD exhibit include:

Having a short attention spanForgetfulness Carelessness and losing things oftenStruggling to stay organizedProblems following directionsStruggling to pay attention to detailsGetting distracted easily

Primarily Hyperactive/Impulsive ADHD

This subtype involves experiencing more hyperactivity and impulsivity. Characteristics of this subtype include:

Restlessness, fidgeting, and an inability to sit stillTalking excessively and trouble being quiet during activitiesProblems focusing on tasksBeing impatientActing impulsively without thinkingFrequently interrupting other

Combined ADHD

Children with this type of ADHD exhibit characteristics of hyperactivity/impulsivity along with inattention. To be diagnosed with this subtype, children must experience six signs of hyperactivity/impulsivity and six sign of inattention.

ADD vs. ADHD in Adults

The characteristics of ADHD may change as people age. For example, people who were primarily hyperactive/impulsive during childhood may find that these traits become less prominent or present differently in adulthood. For example, hyperactivity in a child often involves being very physically active and unable to sit still in class. As an adult, hyperactivity might show itself in less obvious ways. For example, you may have workaholic tendencies, talk a lot, fidget constantly, or drive very fast. In other cases, adults may have the primarily inattention type ADHD, which is what people often mean when they use the term ADD. Adults may also be diagnosed with the combined type. In those over age 17, five signs of both hyperactivity and inattention must be present to receive a diagnosis.

ADHD Is a Form of Neurodivergence

In addition to the many name changes over the years, our understanding of what it means to have ADHD characteristics has also shifted as research has shed more light on different forms of neurodivergence. ADHD is a disability, but this is primarily because society is neurotypically-centered. ADHD is not an “abnormality.” Instead, it represents a form of neurodivergence, which means differences in how a person’s brain functions. Neurodivergent people may behave, learn, and process information differently than what is regarded as “typical.” While it can be helpful to understand how ADHD characteristics can influence a person’s ability to function in their environment, it is important to remember that it is a genetic neurotype and not a disorder that needs to be cured. Different approaches can help a person manage their ADHD traits, but each person is unique, and there is no single strategy that works for everyone.  If you or your child has ADHD, understanding traits and recognizing strengths can be helpful. It can also be beneficial to explore lifestyle adjustments and coping strategies that work best for you.
