ADHD Mortality Study: Review of 16 Million People Finds 70% Higher Risk of Early Death

A new review in JAMA Network Open pooled data from close to 16 million people. It found that people with ADHD had a 70% higher risk of dying early than people without the condition, with the largest increases from suicide and injuries. The same review found early signs that treatment may help. Below is what the ADHD mortality study found, how strong the evidence is, and what it means for families.

The paper is titled “Mortality Among People With Attention-Deficit/Hyperactivity Disorder: A Systematic Review and Meta-Analysis” and was published October 19, 2026. Researchers at University College London (UCL) and the University of Liverpool led the work. It adds to evidence that ADHD affects more than attention and school performance: it is also linked to long-term health and survival.

What the ADHD Mortality Study Found

The team combined results from 19 observational studies published between 2012 and 2025, covering more than 15.9 million people in the U.S., Canada, Sweden, Denmark, Finland, the U.K., and Taiwan. Some of the studies followed participants for more than 20 years. Compared with people without ADHD, people with ADHD had higher death rates in every category the researchers examined, as reported by UCL:

A possible role for treatment

The review also found that people with ADHD who took ADHD medication had about a 25% lower risk of death than people with ADHD who did not. The authors note that only 3 of the 19 studies addressed this question, so they describe the evidence as early. The analysis also did not separate the effects of individual medicines.

Why Might ADHD Be Linked to Earlier Death?

The study was not designed to answer this question. The researchers offered several possible explanations, based on their own earlier work and the wider literature:

• Mental health: higher rates of anxiety, depression, and other conditions, along with difficulties with emotional regulation and impulse control.
• Accidents: attention differences and risk-taking may contribute to unintentional injuries, such as road crashes.
• Physical health: higher rates of cardiovascular disease, metabolic disorders, and diabetes, plus health behaviors such as smoking and alcohol use.
• Barriers to care: trouble accessing healthcare and sticking with treatment, along with stigma, social exclusion, and disadvantage.

How Strong Is the Evidence?

Analysis: A meta-analysis this large is among the strongest ways to measure an association. It also has important limits, several of which the authors raised themselves:

• Association, not causation. All 19 studies were observational. The authors wrote that the methods “are not intended to show cause and effect.” The results do not show that ADHD itself causes earlier death, or that medication is what lowers the risk.
• Studies varied widely. Estimates differed considerably between countries and studies. Possible reasons include differences in healthcare systems, how ADHD is diagnosed, and gender balance. The pooled numbers are averages across very different populations.
• Thin medication data. The medication finding rests on only three studies. People who get treated may also differ in other ways, such as access to care, which could explain part of the gap.
• Some findings differ from earlier work. An earlier review found no link between ADHD and deaths from natural causes. The authors suggest the newer studies they included may explain the difference.

What the Researchers Said

• Senior author Professor Joshua Stott (UCL Psychology and Language Sciences) said that “ADHD is not by definition a life-limiting condition” and that “the right support and treatment can help people with ADHD to live long and healthy lives.”
• First author Lucy Corrigan (University of Liverpool) pointed to “early evidence to suggest that medication may play an important role in supporting the health of people with ADHD.”
• Co-senior author Dr. Amber John (UCL and University of Liverpool) said equitable access to evidence-based assessment and treatment is vital.

Why This Matters in the U.S.

ADHD is common in adults, not only children. A CDC report estimated that about 15.5 million U.S. adults, roughly 6%, had a current ADHD diagnosis in late 2023, and that many were first diagnosed as adults. Many people still go undiagnosed, or are diagnosed without treatment or follow-up.

Practical Takeaways

These general points come from the study’s findings. They are not personal medical advice.

• Don’t ignore possible symptoms. Adults and parents who suspect ADHD can ask a primary care clinician, psychiatrist, or psychologist about a proper evaluation.
• Look at the whole person. Because much of the extra risk is linked to mental health and injuries, ask your clinician about screening for anxiety and depression, and keep up routine physical checkups.
• Talk before changing treatment. Decisions to start, change, or stop ADHD medication should be made with a prescriber, who can weigh benefits and side effects.
• Focus on everyday safety. Reasonable steps include safe-driving habits, limiting alcohol, and avoiding smoking.
• Get help in a crisis. If you or someone you know is struggling or having thoughts of suicide, call or text 988 to reach the 988 Suicide & Crisis Lifeline in the U.S., or call 911 in an emergency.
