People With A.D.H.D. Are Likely to Die Significantly Earlier Than Their Peers, Study Finds
The New York Times
A large study found that men lost seven years of life expectancy and women lost nine years, compared with counterparts without the disorder.
A study of more than 30,000 British adults diagnosed with attention deficit hyperactivity disorder, or A.D.H.D., found that, on average, they were dying earlier than their counterparts in the general population — around seven years earlier for men, and around nine for women.
The study, which was published Thursday in The British Journal of Psychiatry, is believed to be the first to use all-cause mortality data to estimate life expectancy in people with A.D.H.D. Previous studies have pointed to an array of risks associated with the condition, among them poverty, mental health disorders, smoking and substance abuse.
The authors cautioned that A.D.H.D. is substantially underdiagnosed and that the people in their study — most of them diagnosed as young adults — might be among the more severely affected. Still, they described their findings as “extremely concerning,” highlighting unmet needs that “require urgent attention.”
“It’s a big number, and it is worrying,” said Joshua Stott, a professor of aging and clinical psychology at University College London and an author of the study. “I see it as likely to be more about health inequality than anything else. But it’s quite a big health inequality.”
The study did not identify causes of early death among people with A.D.H.D. but found that they were twice as likely as the general population to smoke or abuse alcohol and that they had far higher rates of autism, self-harming behaviors and personality disorders than the general population. In adulthood, Dr. Stott said, “they find it harder to manage impulses, and have more risky behaviors.”
He said health care systems might need to adjust in order to better serve people with A.D.H.D., who may have sensory sensitivity or difficulty managing time or communicating with clinicians during brief appointments. He said he hoped treatments for substance abuse or depression could be adapted for patients with A.D.H.D.
