Insomnia Emerging as Key Factor in Lower Quality of Life Among Adults with ADHD Traits, Study Finds

A newly published study has identified insomnia as a potential driving force behind the reduced quality of life often experienced by adults exhibiting traits of attention deficit hyperactivity disorder (ADHD). Conducted by researchers from the University of Southampton and the Netherlands Institute for Neuroscience, the findings were published in BMJ Mental Health and draw on data from over 1,300 adults in the Netherlands Sleep Registry.

The research reveals that core features of ADHD—such as impulsivity and hyperactivity—are closely associated with severe insomnia, poor sleep quality, and a tendency for late bedtimes and wake times. Sleep disruption, in turn, impairs attention and emotional regulation, creating what the study’s senior author, Dr. Sarah L. Chellappa, describes as a “reinforcing cycle” between sleep disturbances and ADHD behaviors. Dr. Chellappa noted,

“Sleep disruption can impact neurobehavioral and cognitive systems, including attention and emotional regulation. At the same time, sleep disruption may arise from ADHD-related impulsivity and hyperactivity, suggesting a reinforcing cycle between sleep disorders and ADHD.”

At least one in four people with ADHD experience a sleep disorder, with insomnia being the most common. People with ADHD are also diagnosed with sleep disorders about eight times more often than the general population. This prevalence is troubling, as insomnia in adults with ADHD traits is now linked not just to sleep quality, but to overall life satisfaction and mental health.

Professor Samuele Cortese, a co-author of the study, highlighted that low quality sleep and depressive symptoms appear to go hand-in-hand with ADHD traits and collectively contribute to reduced well-being. The authors suggest improving insomnia in individuals with ADHD may offer a promising avenue to enhance life satisfaction.

The researchers urge further investigation into the complex interplay between ADHD and sleep disturbances. They emphasise that targeted interventions addressing insomnia could help break the cycle and significantly improve the lives of people with ADHD.
