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.

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.

Having attention deficit hyperactivity disorder is associated with a shorter life expectancy and a greater risk of mental health issues, a new study has found.

A new study that looked at people with attention-deficit hyperactivity disorder, or ADHD, has found a correlation between people with the disorder and a shorter life expectancy.

“The evidence that people with diagnosed ADHD are living shorter lives than they should is extremely concerning, and highlights unmet support needs that require urgent attention,” the scientists wrote in their paper, published Thursday in The British Journal of Psychiatry.

A large study found that men lost seven years of life expectancy and women lost nine years, compared with counterparts without the disorder.
