The Impact of ADHD on Life Expectancy: Study Findings and Support Strategies

A recent study estimates that adults diagnosed with attention-deficit hyperactivity disorder (ADHD) have a shorter life expectancy compared to those without the condition. Published in The British Journal of Psychiatry, the research suggests that females with ADHD live an average of 8.64 years less, while males with ADHD have a reduced lifespan by 6.78 years.

According to the authors, this disparity is not directly caused by ADHD itself but is likely linked to co-existing health conditions, unmet medical needs, and lifestyle factors such as smoking and substance use. Below, we explore the study’s key findings and share expert advice on how to support loved ones with ADHD.
