Diagnosing and Treating the Aging ADHD Brain

Inside the Aging ADHD Brain

The latest research on how the ADHD brain changes over time. Plus the differences among normal aging, mild cognitive impairment, early dementia, and some classic attention deficit symptoms, and why it is never too late to be diagnosed and treated for ADHD.

After more than 40 years of psychoanalysis,behavioral therapy, and bitter frustration, it was a 2006 TV talk show that finally pointed 63-year-old Zophia in the right direction.
“Everyone told me there was nothing wrong with me,” she said. “But I had such yearning, such anguish inside. I wanted to excel, but something was holding me back.” Zophia flipped on the TV one Saturday morning, and the host launched into a frank confession about her own ADHD. “The more I heard, the more I knew she was talking about me, too,” said Zophia.
She made an appointment with a local psychologist, who ordered a battery of eight one-hour tests. The conclusion was unambiguous: ADHD. “After I found out about ADHD, I thought, ‘Gee, Zophia, why didn’t you come up with that answer a long time ago?’”
For John Washbush, the road to diagnosis took seven decades. “For 70 years, I lived my life day-by-day in the dark, totally clueless,” he said. “I got the same instructions as everyone else, I went through the same motions as everyone else, but rarely did I get the same results.”
In his early 60s, he suspected he had ADHD, but it was still a long road to the official verdict. “I was diagnosed at 70 and took my first dose of Ritalin on my 72nd birthday,” he said. “I knew within 20 minutes that I was on a path to discovering the real me.”

Zophia and John are among a growing number of older adults who are being diagnosed with ADHD at 40, 50, 60, and beyond. Clinicians report a steady increase in requests for ADHD testing by bewildered yet determined adults who grew up in the 1940s, 1950s, and 1960s, when ADHD was rarely recognized in children, let alone adults.
There is a lack of hard data on the aging ADHD population. Most researchers are reluctant to add the confounding factor of age (50+) to ADHD studies. A few pioneering studies from around the world indicate that the prevalence of ADHD among older adults (ages 45-85) is probably about 3 percent, slightly lower than the estimated 4.4 percent prevalence among adults up to age 44. The prevalence for children is estimated at 8 to 9 percent.
Like Zophia and John, most older ADHD adults have spent years trying to answer a question: “What’s wrong with me?” Most have been previously diagnosed with other psychological disorders, most frequently depression, anxiety, bipolar disorder, and learning difficulties. ADHD coexists with several other conditions, so the original diagnoses were probably accurate but were incomplete.

Less sleep may mean faster brain aging for older adults

When older adults get less sleep, it may mean their brains age faster according to a recent study.

Researchers at Duke-NUS Graduate Medical School Singapore (Duke-NUS) have found evidence that the less older adults sleep, the faster their brains age. These findings, relevant in the context of Singapore's rapidly ageing society, pave the way for future work on sleep loss and its contribution to cognitive decline, including dementia.
Past research has examined the impact of sleep duration on cognitive functions in older adults. Though faster brain ventricle enlargement is a marker for cognitive decline and the development of neurodegenerative diseases such as Alzheimer's, the effects of sleep on this marker have never been measured.
The Duke-NUS study examined the data of 66 older Chinese adults, from the Singapore-Longitudinal Aging Brain Study(1). Participants underwent structural MRI brain scans measuring brain volume and neuropsychological assessments testing cognitive function every two years. Additionally, their sleep duration was recorded through a questionnaire. Those who slept fewer hours showed evidence of faster ventricle enlargement and decline in cognitive performance.
"Our findings relate short sleep to a marker of brain aging," said Dr June Lo, the lead author and a Duke-NUS Research Fellow. "Work done elsewhere suggests that seven hours a day(2) for adults seems to be the sweet spot for optimal performance on computer based cognitive tests. In coming years we hope to determine what's good for cardio-metabolic and long term brain health too," added Professor Michael Chee, senior author and Director of the Centre for Cognitive Neuroscience at Duke-NUS.
