A review of nearly 16 million people found higher rates of death from suicide, injuries and natural causes among those with ADHD, while researchers stressed that the findings show association rather than proof of causation.
A new systematic review in JAMA Network Open suggests that attention-deficit/hyperactivity disorder is associated with a substantially higher risk of premature death, although the researchers stress that the findings do not mean ADHD itself directly shortens life. Drawing on 19 studies covering nearly 16 million people across North America, Europe and Asia, the review found that people with ADHD had a 71% higher rate of death from any cause than those without the condition.
The analysis points to a risk profile that extends well beyond one type of death. According to the JAMA Network Open paper, deaths by suicide were 89% higher among people with ADHD, deaths from injuries were 55% higher and deaths from natural causes were 27% higher. The researchers, led by teams at the University of Liverpool and University College London, said the pattern may reflect a combination of factors, including higher levels of depression, anxiety and substance use, as well as social disadvantage, stigma and greater exposure to dangerous situations such as transport accidents.
The review also found that, among people with ADHD, those taking ADHD medication had a 25% lower rate of death from any cause. But the authors cautioned that this result rests on only three studies and should not be taken as proof that medication itself prevents death. A separate study in JAMA looking at ADHD pharmacotherapy reported that starting medication was associated with a lower risk of death from natural causes, adding to interest in whether treatment may reduce some of the broader health risks linked with the disorder.
The wider evidence base still has important limits. All of the studies in the review were observational, which means they can show associations but not establish cause and effect. The authors also said the strength of the mortality gap varied between studies, even though every one pointed in the same direction. Some of the excess risk may be explained by other psychiatric conditions or overlapping diagnoses such as autism. In practical terms, the message for families is one of vigilance rather than alarm: watch for hopelessness, withdrawal, rising substance use or reckless behaviour, and seek help quickly if concerns arise. The researchers called for better-designed studies with more consistent methods, while stressing that timely diagnosis, evidence-based treatment and access to support may help people with ADHD live long and healthy lives.
