Attention Deficit Hyperactivity Disorder, or ADHD, is often seen as a condition that simply causes restlessness or lack of focus, especially in children. But new research is showing that ADHD is much more complex, affecting both mental and physical health in deep ways—and even reaching into a person’s social life, education, and long-term well-being.
Researchers from the University of Nottingham and Nottingham Trent University reviewed over 125 studies and published their findings in Frontiers in Psychiatry. What they found paints a clearer and more serious picture of ADHD. It’s not just about difficulty paying attention or being hyperactive.
People with ADHD are much more likely to face challenges with mental health, including higher risks of depression, suicidal thoughts, addiction, eating disorders, and personality disorders. These issues often go hand-in-hand with ADHD, and without the right kind of help, they can make life much harder.
Physical health is also a major concern. The research showed that people with ADHD are more likely to deal with obesity, sleep problems, dental issues, injuries, and other long-term illnesses.
These problems are not often talked about when it comes to ADHD, but they are just as important. It shows why doctors and health professionals need to look at both the mind and the body when treating ADHD—not just the attention and behavior symptoms.
In the UK, ADHD affects about 5% of the population. That’s roughly one child in every classroom, and about 3% of adults. The condition can affect almost every part of life: school, family, work, relationships, and even how safe someone is.
People with ADHD are 60% more likely to go through a divorce, 30% more likely to attempt suicide, and 35% more likely to be involved in accidents.
ADHD can also have effects beyond the individual. The condition is linked with higher rates of job loss, lower school grades, problems with the law, and poorer overall quality of life.
Many people with ADHD also take more risks and struggle to maintain stable friendships or romantic relationships. These challenges highlight how important it is for society to better understand and support people living with ADHD.
One of the lead researchers, Dr. Blandine French, has a personal connection to the topic. She was diagnosed with ADHD as an adult, after working for years in the hospitality industry. Her experience helped her see how much ADHD can affect someone’s daily life, and she returned to university to study the condition more deeply.
Dr. French believes that we need to rethink how we treat ADHD. Instead of only focusing on behavior, she says we need to also address the emotional, physical, and social effects.
The UK’s National Health Service (NHS) is beginning to take these findings seriously. NHS England has created a task force to improve support services for people with ADHD. This team will focus on creating better connections between schools, healthcare systems, and even the legal system to make sure people with ADHD don’t fall through the cracks.
Dr. French hopes this new approach will help people get the support they need sooner—especially for physical problems that are often missed. Professor David Daley, another lead researcher, agrees that ADHD should be taken more seriously and given higher priority in healthcare systems.
This study reminds us that ADHD is not just about struggling to sit still or pay attention. It affects many parts of a person’s life, and the consequences can be severe if it’s not understood or treated properly.
By changing how we think about ADHD—and by offering more complete, compassionate care—we can give people living with this condition a much better chance at a healthy, fulfilling life.
