Study links ADHD to higher risk of dementia and cognitive impairment in older age
A University of Pittsburgh-led study in JAMA Psychiatry found older adults with ADHD were more likely to develop dementia or cognitive impairment. It is observational and cannot show ADHD causes dementia.

The story, neutrally told
Mixed · 2A study published in JAMA Psychiatry on 7 October found that older adults with ADHD were more likely to develop cognitive impairment or dementia than those without the condition. NewsweekN “The study was published in the journal JAMA Psychiatry on October 7.” Read at Newsweek ↗ Daily MailR “People with attention deficit hyperactivity disorder - ADHD - are significantly more likely to develop dementia, a study suggests.” Read at Daily Mail ↗ Mixed · 2The Daily Mail reported that researchers from the University of Pittsburgh tracked 187,341 older adults over ten years, 3,026 of whom had an ADHD diagnosis. Newsweek described the sample as almost 200,000 Americans aged 50 or older. Daily MailR “Researchers from the University of Pittsburgh tracked 187,341 older adults over ten years, of which 3,026 had an ADHD diagnosis.” Read at Daily Mail ↗ NewsweekN “The team of researchers reviewed the clinical data of almost 200,000 Americans aged 50 or older” Read at Newsweek ↗ Mixed · 2About 6.7% of those with ADHD went on to develop memory problems, defined as dementia or mild cognitive impairment, compared with 3.4% of those without ADHD (Newsweek: around 7% versus 3%). Daily MailR “They found 6.7 per cent of those with ADHD went on to develop memory problems” Read at Daily Mail ↗ NewsweekN “around 7 percent of the participants who had ADHD went on to develop cognitive impairment, compared to 3 percent of those without ADHD” Read at Newsweek ↗
Right · 1According to the Daily Mail, a more detailed analysis accounting for age raised the increased risk to as much as four-fold, and to three-fold when looking only at dementia diagnoses. It said the three-fold risk held after adjusting for physical and mental health conditions, education, smoking and healthcare use. Daily MailR “When looking only at those with dementia diagnoses, the increased risk was three-fold.”“The three-fold risk held true even after scientists adjusted for other factors that could explain the link” Read at Daily Mail ↗ Centre · 1Newsweek added that people with ADHD who developed cognitive impairment had poorer mental health, lower quality of life and social satisfaction, and used health services more than people with cognitive impairment but no ADHD. NewsweekN “"poorer mental health, lower quality of life and social satisfaction, and used health services more, compared with people with cognitive impairment who did not have ADHD."” Read at Newsweek ↗ Right · 1The study was observational, so it cannot prove that ADHD causes dementia. The researchers also said some ADHD diagnoses may have reflected early, unrecognised symptoms of cognitive decline. Daily MailR “Crucially, the study was observational, meaning it cannot prove ADHD itself causes dementia.”“some ADHD diagnoses could have reflected early, unrecognised symptoms of cognitive decline” Read at Daily Mail ↗
Mixed · 2The authors offered two main explanations: ADHD may be linked to lower cognitive reserve, and ADHD may increase exposure to cumulative risk factors such as chronic stress, sleep problems, physical inactivity, poor diet, heart risk and substance use. Daily MailR “'A second hypothesis,' the authors continued, 'is that ADHD increases exposure to cumulative risk factors for cognitive impairment.'” Read at Daily Mail ↗ NewsweekN “associated with lower cognitive reserve or resilience” Read at Newsweek ↗ Centre · 1Co-first author Dr Douglas Teixeira Leffa told Newsweek that why people with ADHD may be more likely to develop dementia "remains a crucial unanswered question", and that there is no convincing evidence yet on whether ADHD treatment or better management of risk factors changes later cognitive outcomes. NewsweekN “"why individuals with ADHD may be more likely to develop dementia remains a crucial unanswered question."”“"we do not have convincing evidence to answer that question."” Read at Newsweek ↗ Centre · 1Greg Fabiano, a Florida International University psychology professor not named as an author, said the findings add to evidence that ADHD is a risk factor for difficult outcomes across the lifespan. He said ADHD treatment should be seen as long-term support rather than a short-term fix. NewsweekN “add to the accumulating research evidence that having ADHD is a risk factor for challenging outcomes across development, up to and including later adulthood.”“treatments cannot be viewed as short-term fixes” Read at Newsweek ↗
Mixed · 2Both outlets said the study is not the first to link ADHD and dementia. The Daily Mail cited a 2023 JAMA Network Open study that found an almost three-fold greater dementia risk in adults diagnosed with ADHD. Daily MailR “Separate research published in 2023 in the journal JAMA Network Open also found that adults diagnosed with ADHD had an almost three-times greater risk of developing dementia.” Read at Daily Mail ↗ NewsweekN “The findings build on previous studies discovering an association between adult ADHD and a higher risk of developing dementia” Read at Newsweek ↗ Mixed · 2For context, the Daily Mail said ADHD is thought to affect 2.5 million people in England and almost one million Britons live with dementia, while Newsweek cited the CDC figure of around 15.5 million US adults with ADHD. Daily MailR “Almost one million Britons are living with dementia, which claims 76,000 lives a year as Britain's biggest killer.” Read at Daily Mail ↗ NewsweekN “Around 15½ million U.S. adults have ADHD, according to the Centers for Disease Control and Prevention (CDC).” Read at Newsweek ↗

Centre1 outlet
- Framing
- Newsweek presents a measured research explainer on cognitive impairment in people with ADHD, built around quotes from the study's co-first author and an outside psychologist.
- Emphasis
- Mechanisms, worse health outcomes for those affected, unanswered questions on treatment, and the need for long-term monitoring and care.
- Leaves out or plays down
- Does not give the sample size exactly, the dementia-only risk ratios, or the observational-design caveat in so many words.
- For example
-
“experts say this highlights the need for more research to understand the connection, as well as greater and more targeted monitoring and care for those with ADHD as they get older.” — Newsweek
Right1 outlet
- Framing
- The Daily Mail leads with a headline risk figure, 'four times more likely', and ties it to the national burden of dementia.
- Emphasis
- Risk multiples, lifestyle factors, NHS prevention advice, UK dementia and ADHD numbers, and its Defeating Dementia campaign with the Alzheimer's Society.
- Leaves out or plays down
- Does not quote the authors or outside experts by name. The headline's four-fold figure sits beside the 6.7% versus 3.4% raw rates, which are roughly double, and the body says three-fold for dementia alone.
- Charged language
- “major study”
- For example
-
“People with ADHD may be up to four times more likely to develop dementia or memory problems in later life than those without the disorder, a major study claims” — Daily Mail
What every side reports
- The study was published in JAMA Psychiatry.
- Roughly 7% of older adults with ADHD developed cognitive impairment or dementia, against about 3% of those without ADHD.
- The study does not establish why the two are linked; earlier research had also found an association.
- Proposed explanations include lower cognitive reserve and greater exposure to risk factors such as sleep problems, inactivity and chronic stress.
Where accounts differ
-
How large the increased risk is
- Centre
- Newsweek reports about 7% versus 3% developing cognitive impairment and does not give a risk multiple.
- Right
- The Daily Mail's headline says 'four times more likely' and its body says up to four-fold, and three-fold for dementia alone; its raw rates are 6.7% versus 3.4%.
