ADHD wasn't "discovered" at a single moment, but its symptoms were first medically noted in 1798 by Sir Alexander Crichton and then detailed by Sir George Frederic Still in 1902, who described an "abnormal defect of moral control" in inattentive children, though it took until the 1980s for terms like ADD and ADHD to formalize, with DSM-III (1980) and DSM-III-R (1987) shaping modern understanding and naming.
Medical textbooks in the 1800s did refer to children who had what we think of today as ADHD symptoms. They used a number of different names for the condition: “nervous child,” “hypermetamorphosis,” “mental instability,” “unstable nervous system,” and “simple hyperexcitability” were among them.
Along the 20th century, “minimal brain damage”, “minimal brain dysfunction”, “minimal brain disorder”, “hyperkinesis” or simply the “hyperactive child syndrome” are among the many different terms used to refer to what is currently known as ADHD[5-7].
Increased mental health concerns (especially stress, anxiety and depression) were reported by youth, parents and teachers. These mental health concerns led to more diagnostic evaluations which, in turn, led to increased ADHD diagnoses. (Without an evaluation, there is no diagnosis.)
The rate of ADHD diagnoses has been rising in the US for the past two decades, and experts hypothesize that social media and the pandemic may be a catalyst. More Americans are seeking out treatment for ADHD all at once, which is putting strain on an already stretched thin health-care system.
While misdiagnosis does happen, research suggests that ADHD is still more often underdiagnosed rather than overdiagnosed, especially in women, ethnic minorities, and older adults.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
The 20-minute rule for ADHD is a productivity strategy to overcome task paralysis by committing to work on a task for just 20 minutes, leveraging the brain's need for dopamine and short bursts of focus, making it easier to start and build momentum, with the option to stop or continue after the timer goes off, and it's a variation of the Pomodoro Technique, adapted for ADHD's unique challenges like time blindness. It helps by reducing overwhelm, providing a clear starting point, and creating a dopamine-boosting win, even if you only work for that short period.
So, ADHD and ASD aren't the same condition, but — because they have so many similarities — it's easy to confuse them. After all, it's not like there's a specific spot on the brain where ASD stops and ADHD begins.
Country-wise, Haiti has the highest share of teens and adults diagnosed with ADHD at 4.6%. among countries, the highest ADHD rate is observed in Haiti (4.6%), Iran (3.5%), Australia (3.4%), Algeria (3.4%, and Brazil (2.7%).
Johnny Depp is a legendary actor, famous for his diverse roles in films like “Pirates of the Caribbean” and “Edward Scissorhands.” He was diagnosed with ADHD as an adult and has faced challenges associated with the condition.
Increase stress relief by exercising outdoors—people with ADHD often benefit from sunshine and green surroundings. Try relaxing forms of exercise, such as mindful walking, yoga, or tai chi. In addition to relieving stress, they can teach you to better control your attention and impulses.
However, the diagnosis of ADHD and prescription of ADHD medication has increased substantially worldwide over the last decade. A recent study reported an annual rise of 9.7% in ADHD medication use across 64 countries between 2015 and 2019.
Albert Einstein, Physicist & Mathematician
Although it can't be proven, many scholars and historians believe that Einstein one of the greatest minds of all-time, had ADHD.
ADHD is a protected disability under the Rehabilitation Act of 1973 and the Americans with Disabilities Act (ADA). Individuals whose symptoms of ADHD cause impairment in the work setting may qualify for reasonable work accommodations under ADA. Read more on ADHD in Adults.
8 Most Successful People with ADHD
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
For instance, a child with ADHD may struggle with social interactions due to impulsivity and inattentiveness, while a child with autism might have social difficulties stemming from challenges in understanding social cues and communication. However, the underlying reasons for these behaviours differ significantly.
For adults, 7-8 hours is recommended. Try to avoid napping during the day.
There are several alternatives to ADHD medication, each with its unique benefits. While holistic approaches may take time, they can lead to sustainable improvements without unwanted side effects. Some of the most common alternatives include cognitive behavioral therapy, exercise, mindfulness, and diet modifications.
Here are several explanations of why people with ADHD procrastinate: Low motivation: The brain is deficient in a chemical messenger called dopamine, which is responsible for pleasure and motivation. Lower dopamine levels can make it harder to find an activity that's fun, exciting, or rewarding enough to complete.
The top 3 core symptoms of ADHD are inattention (difficulty focusing, staying organized), hyperactivity (excess restlessness, excessive movement), and impulsivity (acting without thinking, poor self-control). People with ADHD often experience a combination of these, though some might primarily struggle with inattention (inattentive type) or hyperactivity/impulsivity (hyperactive-impulsive type).
The only way to know for sure is to see a doctor. That's because the disorder has several possible symptoms, and they can easily be confused with those of other conditions, such as depression or anxiety. Everyone misplaces car keys or jackets once in a while. But this kind of thing happens often when you have ADHD.
