A new study from the University College London found that men with ADHD have a reduced life expectancy of 6.78 years, and its worse for women.

On average, women diagnosed with attention-deficit/hyperactivity disorder died almost nine years earlier, while men died almost seven years earlier, the U.K. study found.

Researchers found an apparent reduction in life expectancy for men with diagnosed ADHD of between 4.5 and 9 years and between 6.5 and 11 years for women
