ADHD Mortality: Review of 15.9 Million People Links ADHD to Earlier Death, but Medication to Lower Risk

What the study found

ADHD mortality has been looked at in one of the biggest evidence reviews so far. A team from the University of Liverpool and UCL, with lead author Lucy Corrigan, a research assistant in Liverpool's Department of Psychology, pooled 19 studies published between 2012 and 2025. Together they covered 15,920,970 people with ADHD in the US, Canada, Sweden, Taiwan, Denmark, Finland and the UK. The review was published in JAMA Network Open on 19 October 2026 and reported by Healio on 29 October.

The key figures

Twelve of the studies were combined in the main analysis. Compared with people without ADHD, people with ADHD had a higher risk of:

• dying from any cause (hazard ratio 1.71, which UCL describes as a 70% higher rate)
• death by suicide (1.89, around 90% higher)
• death from injuries, accidental or intentional (1.55, around 55% higher)
• death from natural causes (1.27, around 27% higher)

The medication link

Among people with ADHD, those taking ADHD medication had a lower risk of dying from any cause (hazard ratio 0.75, roughly 25% lower). That's the encouraging part, but it's based on only three of the 19 studies. Corrigan said: "Although we cannot conclude from these observational findings that medication directly reduces mortality, this is an encouraging finding that warrants further investigation."

A link, not proof

Every study in the review was observational. That means it shows an association, not cause and effect. It doesn't prove ADHD itself shortens lives, and it doesn't prove medication saves them. The authors also point out some limits:

• Results varied a lot between studies, especially for suicide.
• Men were over-represented. Only 36.1% of participants were women.
• Study sizes differed, and the way ADHD is seen and diagnosed varies from country to country.

Why it matters

It backs up something a lot of people with ADHD already know: it isn't just about focus, it can affect your whole health. Corrigan said the link with natural-cause deaths suggests "we should pay greater attention to physical health, preventive care and the barriers that some people with ADHD may face in accessing healthcare or following treatment plans." She added: "Ultimately, the clinical message is that people with ADHD deserve timely access to treatment and ongoing support that addresses their overall health."

Looking after yourself

None of this means something bad is going to happen to you. It's a picture across millions of people, not a prediction for one person. If routine health checks are the kind of thing that slides off your list, it's worth putting the next one somewhere you'll actually see it. And if your mood has been low for a while, don't just push through it. Tell someone you trust, or mention it to your GP.

Your own treatment

This is research news, not medical advice. If you take ADHD medication, or you're wondering about it, this study isn't a reason to start, stop or change anything on your own. Never stop or change your medication without talking to your GP or prescriber first.
