People with ADHD face significantly higher odds of dying from all causes, including suicide, injury, and natural causes, according to a sweeping meta-analysis of nearly 16 million people. The silver lining? ADHD medication was linked to a 25% reduction in all-cause mortality risk. Researchers say timely diagnosis and treatment are critical to closing the gap.
A major systematic review and meta-analysis published in JAMA Network Open found that people with ADHD face a 71% higher risk of all-cause mortality compared to those without the condition. The study pooled data from 19 studies across seven countries covering nearly 16 million individuals, and also found elevated risks for suicide, unintentional or intentional injury, and natural-cause death.
Researchers point to several pathways driving this risk: ADHD-related impulsivity and risk-taking behaviors, co-occurring mental health conditions like depression, lifestyle factors such as smoking and alcohol use, and barriers to accessing consistent healthcare. Despite substantial variation across studies, all consistently showed higher mortality in ADHD groups.
By the Numbers:
Why it matters: With an estimated 15 million U.S. adults living with ADHD — many going undiagnosed or untreated — these findings make a compelling case for expanding access to timely diagnosis and comprehensive, long-term treatment to meaningfully reduce preventable deaths.
