Adults diagnosed with ADHD have shorter life expectancy, UK study shows

Data based on recorded deaths raises concerns around under-diagnosis of attention deficit hyperactivity disorder

Men with a diagnosis of ADHD die seven years sooner, on average, than similar people without, while for women the life expectancy gap is almost nine years, the first study of its kind has revealed.

Attention deficit hyperactivity disorder can cause difficulties in concentration and problems with impulsiveness, although people with ADHD do not necessarily experience both. While estimates vary, studies suggest 3-4% of adults worldwide have ADHD.
