Insomnia could be key to lower life satisfaction in adults with ADHD traits, study finds
Insomnia could explain why adults with ADHD traits report having a lower quality of life, according to new research led by the University of Southampton and the Netherlands Institute of Neuroscience.
A study published today [15 July] in BMJ Mental Health found that having higher ADHD traits was associated with a lower quality of life and that insomnia could be part of the reason why.
At least one in four people with attention deficit hyperactivity disorder (ADHD) report having a sleep disorder, with insomnia being the most common of these.
“Our findings show a link between ADHD traits, insomnia severity, and reduced life satisfaction,” says Dr Sarah L. Chellappa, Associate Professor in Psychology at the University of Southampton and senior author on the research paper.
“We know that 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.”
Researchers from the University of Southampton and the Netherlands Institute for Neuroscience (Prof Eus Van Someren) examined data from the Netherlands Sleep Registry, an online survey with more than ten thousand adult participants.
The team analysed responses from 1,364 participants who had answered questions about ADHD traits, sleep disturbances, circadian factors, depression, and quality of life.
They found ADHD traits were associated with worse depression, more severe insomnia, lower sleep quality, and a preference for going to bed and waking up later.
ADHD and insomnia severity both predicted a lower quality of life, with analysis suggesting insomnia was the potential link in this association.
“Adults with ADHD traits may be more likely to have low sleep quality, insomnia complaints, and low mood levels, all of which lead to reduced life satisfaction,” says Professor Samuele Cortese, a co-author on the paper, also from the University of Southampton.
“There needs to be more research to understand this complex interplay. By improving our understanding, we could uncover treatment options that improve the quality of life of people with ADHD. For instance, targeting insomnia complaints in individuals with higher ADHD traits, with Cognitive Behavioural Therapy for Insomnia or Sleep Restriction therapy may help improve their quality of life.”
The paper Associations of ADHD symptom severity, sleep/circadian factors, depression, and quality of life is published in BMJ Mental Health and is available online.
The research was supported by the Netherlands Organisation for Scientific Research and the European Research Council.

Study discusses how to mitigate damage from gunshot injuries to the brain in children and young adults

NASHVILLE — A study presented today at the Society of NeuroInterventional Surgery’s (SNIS) 22nd Annual Meeting found that almost half of gunshot wound injuries to the brain in children and young adults include penetrating cerebrovascular injuries (PCVIs). These types of injuries, which damage blood vessels in the brain and may result in high rates of permanent disability and death, may be mitigated if hospitals ...
New research challenges animal dietary classifications in Yellowstone National Park
2025-07-14
PROVIDENCE, R.I. [Brown University] — Scholars and schoolchildren alike have generally classified animals by the foods they eat: carnivores eat meat; browsers consume flowering plants, conifers and shrubs; and grazers focus on grasses.
But a new federally funded study led by Brown University biologists and scientists at Yellowstone National Park revealed that different circumstances lead herbivores to eat a much wider variety of plants than previously believed.
Published in the Proceedings of the National Academy of Sciences, the new research suggests that the traditional classification schemes that distinguish herbivores by their ...
Parenthood not lessening loss for widowed people, 25 years of interviews suggest
2025-07-14
Widowed parents who enjoy close relationships with their adult children still struggle with loneliness, according to the first study of its kind.
Published in the peer-reviewed journal Aging & Mental Health, the analysis spanning 25 years was based on interviews with more than 5,500 men and women including those whose spouse had died.
The findings contradict commonly held assumptions that indicate widowed parents experience much lower levels of loneliness than those without children.
Although the bond between bereaved women and their offspring is strengthened, the authors of this new study say this is insufficient to fill the emotional void left after the death of ...
UC Irvine astronomers discover scores of exoplanets may be larger than realized
2025-07-14
Irvine, Calif., July 14, 2025 — In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It’s a finding that could change which distant worlds researchers consider potential harbors for extraterrestrial life.
“We found that hundreds of exoplanets are larger than they appear, and that shifts our understanding of exoplanets on a large scale,” said Te Han, a doctoral student at UC Irvine and lead author of the new Astrophysical Journal Letters study. “This means we may have actually found fewer Earth-like planets so far than we thought.”

Theory for aerosol droplets from contaminated bubbles bursting gives insight into spread of pollution, microplastics, infectious disease
2025-07-14
Bubbles burst when their caps rupture. Children discover this phenomenon every summer day, but it also underpins key mechanisms for the spread of pollutants, contaminants, and even infectious disease through the generation of aerosol droplets. While bubble bursting has been extensively studied in pure substances, the impact of contaminants on bursting dynamics has not received widespread attention.
Researchers in The Grainger College of Engineering at the University of Illinois Urbana-Champaign have conducted a systematic study to investigate bubble ...

Implantable cell therapy has potential to restore adrenal function and treat primary adrenal insufficiency
2025-07-14
SAN FRANCISCO—Adrenal hormone function was restored in animal studies, potentially paving the way for a functional cure for primary adrenal insufficiency in humans, according to research being presented by Aspect Biosystems on Monday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.
Primary adrenal insufficiency, most commonly due to Addison’s disease or congenital adrenal hyperplasia, is a life-threatening condition that typically requires lifelong adrenal hormone replacement.
However, the current hormone replacement therapies have a significant treatment burden and fail to mimic the natural circadian rhythms of hormone ...
Obesity and type 2 diabetes in teen years can impair bone health
2025-07-14
SAN FRANCISCO—Obesity and type 2 diabetes in adolescence can interfere with bone development, potentially increasing the risk of fractures and osteoporosis later in life, according to a study being presented Monday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.
The teen years are the most critical for building lifelong bone strength, according to lead researcher Fida Bacha, M.D., of Baylor College of Medicine in Houston, Texas. “While adults with type 2 diabetes are known to have increased risk ...
Study finds strong link between acromegaly and increased cancer risk

SAN FRANCISCO—People with the rare growth hormone disorder acromegaly have a significantly higher risk of developing various types of cancer, often at ages younger than typically seen in the general population, according to a study being presented Monday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.
“Our findings suggest that acromegaly may play a bigger role in cancer risk than previously thought, highlighting the need for increased awareness and early cancer ...
