What is ADHD?
ADHD stands for attention deficit hyperactivity disorder, a neurodevelopmental condition that affects the brain's ability to manage attention, impulse control, and planning. It starts in childhood: about 1 in 9 US children have a current diagnosis. But it doesn't stop there. Around 15.5 million US adults live with ADHD, and more than half only found out as adults.
ADHD research has some unusual challenges. Nearly every stimulant on the market comes from just two base medicines, so researchers are now focusing on nonstimulants instead. People in ADHD studies also tend to improve on placebo, which makes results harder to read. And adults, especially women, were overlooked by research for decades, so many studies now recruit them on purpose.
What is the difference between ADD and ADHD?
There is no real difference: ADD is an outdated name for the same condition. Doctors adopted ADD in 1980 and replaced it with ADHD in 1987. The current diagnostic manual does not list ADD at all. What people used to call ADD was attention problems without the hyperactive part. Today that is closest to what doctors call the predominantly inattentive presentation of ADHD.
Types of clinical trials for ADHD
Clinical trials for ADHD include various types of studies aimed at improving treatment and understanding the disorder. These trials often include randomized controlled trials (RCTs), observational studies, and behavioral intervention trials.
Observational studies
Observational studies are designed to watch and learn from those living with ADHD to better understand how symptoms manifest themselves, identify patterns, and gather insights. This could include monitoring a group of participants or studying previously collected data to establish more outcomes.
Researchers may observe people with ADHD in a medical setting, although real-world environments typically offer better outcomes, particularly for children with ADHD. If designed and carried out properly, researchers can gather valuable data that can be used to inform treatment options or preventative measures.
Treatment trials
Treatment trials are used to test new treatments for ADHD. There are several types of treatment trials available to researchers, depending on the objective or desired outcome. One common type is randomized controlled trials (RCTs), where participants are assigned to either a treatment group or a placebo group to test the effectiveness and safety of medications, such as stimulants or non-stimulants.
Researchers may also use behavioral therapy trials to test new therapies, device trials to test new gadgets and tools for ADHD, or combination treatment trials which test medications and therapies or devices together.
Quality of life trials
In quality of life trials, researchers aim to discover ways to improve the lives of those living with ADHD. They are typically designed as a combination trial, observing participants before testing treatments to see which treatments make their life better. Researchers will seek to help participants manage symptoms and enhance their daily function.
Do ADHD trial participants get paid?
Some studies offer compensation for time and travel, and study related care is typically provided at no cost to participants. Compensation varies by trial and is always described during the informed consent process before you agree to anything.

Who can participate in ADHD clinical trials?
Every study sets its own rules. ADHD has no stages, so trials recruit by age and by situation instead. Some take children and adolescents, including the new solriamfetol studies on this page. For a child, a parent or guardian gives permission, and the child agrees too when old enough. Other studies take adults, a group research overlooked for years. And some look for specific situations: pregnant women managing ADHD, adults who have ADHD together with autism, or children with ADHD plus anxiety. Studies usually ask which ADHD presentation you have, and many have rules about the medication you take now. Eligibility always varies by study.
