Attention Deficit Hyperactivity Disorder (ADHD) is a common condition that mainly affects kids. But, it can also impact adults. The Centers for Disease Control and Prevention (CDC) says ADHD is often found in elementary school years. Yet, adults can also show symptoms and get diagnosed.
Boys are more than twice as likely to get ADHD than girls. But, girls are not immune to it. ADHD was once called “hyperkinetic reaction of childhood.” It wasn’t until the 1960s that the American Psychiatric Association (APA) officially recognized it as a mental disorder.
In the 1980s, the name changed to “attention deficit disorder with or without hyperactivity.” This change shows how our understanding of ADHD has grown. It highlights the complex nature of ADHD and its different forms.
Key takeaways
- ADHD was first recognized as a mental disorder in the 1960s, though earlier observations and descriptions existed.
- The diagnosis has evolved from “hyperkinetic reaction of childhood” to “attention deficit disorder with or without hyperactivity.”
- Boys are more than twice as likely to be diagnosed with ADHD compared to girls.
- ADHD can be identified in childhood, but adults can also demonstrate symptoms and be diagnosed.
- The understanding and recognition of ADHD has continued to develop over the decades, with ongoing research providing insights into its causes and treatment.

Early Pioneers and Descriptions
The history of ADHD stretches back centuries. In 1798, Sir Alexander Crichton, a Scottish physician, described a disorder similar to ADHD. He noted how some patients had trouble focusing and staying on one task.
Crichton’s work from the 19th century is key to understanding ADHD’s origins. His early descriptions helped pave the way for later research into this complex condition.
Sir Alexander Crichton’s Observations
In his 1798 book, An Inquiry into the Nature and Origin of Mental Derangement, Crichton detailed his findings on ADHD-like symptoms. He highlighted the challenges these individuals faced with attention and focus. His observations were ahead of their time, predicting today’s understanding of ADHD.
Crichton’s work, though before ADHD was officially recognized, marked a crucial step in its study. His insights set the stage for future research into ADHD.
“The power of attention, in some individuals, is weak from nature, and on the other hand, the incapacity of attending with a necessary degree of constancy to any one object, is an universal symptom of madness.”
Even today, Crichton’s words from over two centuries ago are still relevant. They show how ADHD affects people’s minds and daily lives.
Emerging Terminology and Recognition
Our understanding of ADHD has grown over the years. The words we use to talk about it have changed a lot. In 1902, Sir George Frederic Still noticed kids who were more impulsive and had trouble focusing. This was the start of recognizing ADHD symptoms.
In 1936, the FDA approved Benzedrine, a stimulant. Dr. Charles Bradley found in 1937 that Benzedrine helped kids with ADHD. But, it took years for this to become widely known.
The Benzedrine Effect
Benzedrine was a big step in treating ADHD. It showed that stimulants could help. Even though it wasn’t widely accepted at first, it helped shape how we talk about and treat ADHD today.
“Despite historical criticisms of ADHD, the disorder has a long-established history within the field of mental health.”
The journey to understand ADHD has been long. From Sir George Frederic Still’s early work to ADHD being in the DSM, it’s been a path of growth. As we keep improving how we diagnose and treat ADHD, we must remember its rich history and the ongoing efforts to help those with ADHD.
The Evolution of the Diagnosis

Our understanding of attention deficit hyperactivity disorder (ADHD) has changed a lot over the years. It was first listed in the Diagnostic and Statistical Manual in 1968. Back then, it was called “hyperkinetic reaction of childhood.”
In 1980, the DSM changed it to “attention deficit disorder (ADD).” It split into two types: ADD with hyperactivity and ADD without.
By 1987, it was officially named “attention deficit hyperactivity disorder (ADHD).” This change included symptoms of inattentiveness, impulsivity, and hyperactivity. The ADHD diagnosis evolution and ADHD definition changes were big steps forward. The DSM editions and ADHD helped us understand ADHD better.
The 1994 DSM edition was another big step. It listed three main ADHD types: inattentive, hyperactive-impulsive, and combined. This made it easier for doctors to diagnose and help people with ADHD.
“The evolution of the ADHD diagnosis reflects the ongoing efforts of the scientific community to better understand and classify this complex disorder, which continues to be a subject of debate and research.”
As we learn more about ADHD, so do the treatments and support. The Americans with Disabilities Act of 1990 helped too. It made sure people with ADHD get the help they need.
The journey of ADHD diagnosis has been complex. It has seen changes in how we talk about and understand it. As research keeps going, we’ll see more improvements in how we deal with ADHD. This will help those who live with it.
When Did ADHD Become a Diagnosis?

The history of ADHD diagnosis goes back centuries. Early figures like Sir Alexander Crichton and Sir George Frederic Still described ADHD-like behaviors in the 18th and 19th centuries. But it wasn’t until the mid-20th century that ADHD’s clinical definition started to form. It was then known as “minimal brain damage” and “hyperactivity.”
Over time, how we talk about ADHD has changed a lot. In 1968, the American Psychiatric Association’s DSM-II used “hyperkinetic reaction of childhood.” Then, in 1980, the DSM-III introduced “Attention Deficit Disorder (ADD).” By 1987, it was called “ADHD” in the revised third edition. The DSM-IV in 1994 split ADHD into three types: inattentive, hyperactive/impulsive, and combined.
Several factors have led to more ADHD diagnoses in recent years. These include:
- Doctors can now diagnose ADHD more easily.
- Parents and teachers are more aware and report ADHD symptoms.
- More effective treatments, like stimulants and non-stimulants, have been developed.
Today, over 5 million children in the US have ADHD. Boys are twice as likely to be diagnosed as girls. ADHD diagnoses in adults have also gone up, from 0.43% in 2007 to 0.96% in 2016. This is a 123% increase. While stimulants are still the main treatment, new non-stimulant medications offer more choices for managing ADHD.
The journey of ADHD diagnosis has been long and complex. It has been shaped by early pioneers, changes in medical terms, and the growth of effective treatments. As we learn more about ADHD, its history remains a key part of mental health history.
Conclusion
The idea of ADHD has changed a lot over the last 200 years. People noticed inattentive, hyperactive, and impulsive behaviors as far back as the late 1700s. Even though the name and how we diagnose it have changed, the main symptoms have been known for a long time.
Our understanding of ADHD is getting better with more research. This means we can diagnose it more accurately and help those affected more effectively. About 10% of U.S. kids between 4 and 17 have ADHD. Worldwide, it’s estimated that around 5% of people have ADHD, but this number can vary.
ADHD has a big impact on people’s lives. Many with ADHD also have other conditions. The cost of ADHD in the U.S. is over 143 billion dollars a year. Schools bear a big part of this cost.
Children with ADHD often have trouble in school and with friends. They also visit doctors more often. Adults with ADHD may earn less and need more social help.
