A common neurodevelopmental disorder could be linked to dementia risk, a new study suggests.Research led by the University of Pittsburgh School of Medicine, involving more than 187,000 adults aged 50 and older, found that ADHD (attention deficit hyperactivity disorder) was associated with a substantially increased risk of dementia or mild cognitive impairment (MCI).The observational study looked at electronic health records and genetic information of participants who were enrolled in the U.S. National Institutes of Health All of Us Research Program.7 NEW DEMENTIA RISK FACTORS REVEALED — INCLUDING ONE MILLIONS STRUGGLE WITHCognitive impairment was observed in 6.7% of participants with ADHD versus 3.4% without the disorder — nearly twice the rate.After researchers adjusted for age, gender and other health conditions, those with ADHD had more than four times the risk. A common neurodevelopmental disorder could be linked to dementia risk, a new study suggests.

Pascoal, associate professor of psychiatry and of neurology at Pitt, in a press release.”Two different kinds of evidence are pointing in the same direction.”3 THINGS TO AVOID IN MIDDLE AGE COULD MEAN 13 MORE YEARS WITHOUT DEMENTIA, STUDY FINDSMeanwhile, those with the highest genetic susceptibility to ADHD were found to have a 35% greater risk of dementia than those with the lowest susceptibility.”Analyzing genetic information alongside years of health records allows us to identify patterns that might not be visible in a smaller or more traditional study,” said Guilherme Bauer-Negrini, co-first author and postdoctoral associate in biomedical data science at Pitt, in the release.”It goes back to nature versus nurture — particularly if we’re starting at age 50, as opposed to starting at 20.” “With this kind of data, we can start to investigate what may be driving this association and whether any of those factors could be modified to support healthier cognitive aging.”Understanding the linkDr. Elizabeth Landsverk, a geriatric medicine and dementia expert with over 20 years of experience treating patients with Alzheimer’s and cognitive decline, noted that people with ADHD can have more difficulty with organization, which could contribute to the higher risk of cognitive impairment, although neurological differences may also play a role.”It might [be] that keeping on top of health issues and getting to the doctor is more difficult for them,” Landsverk, a California-based doctor who is not involved in the study, told Fox News Digital. Cognitive impairment was observed in 6.7% of participants with ADHD versus 3.4% without the disorder — nearly twice the rate.

You may not get your blood pressure taken care of. So there’s probably a correlation.”CLICK HERE FOR MORE HEALTH STORIES”It goes back to nature versus nurture — particularly if we’re starting at age 50, as opposed to starting at 20.”ADHD vs dementiaIt can be challenging to distinguish between ADHD and cognitive decline, as some of the symptoms may overlap, according to Landsverk.CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER”I imagine it can look similar,” she said. “You know, you don’t remember why you went into a room. You don’t know where your keys are, you don’t remember the name of an actress.”It is cause for concern if the individual struggles to take care of day-to-day tasks, the expert noted. The findings only show an association and cannot determine that ADHD increases dementia risk, the researchers acknowledged.
