In the study, researchers followed in the records four million Swedes born from 1932-1995 from 1973 to 2013 and examined their risk of developing 35 physical illnesses.
The report’s authors, among other things, compared people with and without a diagnosis of ADHD, and those diagnosed with any siblings without a diagnosis.
People with ADHD were more likely to have all diseases except arthritis, and the risks were greater for alcohol-related liver disease, sleep disturbances, carbon monoxide, epilepsy, fatty liver, and obesity.
A slight decrease in the risk of cardiovascular disease, Parkinson’s disease and dementia was also noted.
Discovering physical illnesses at the same time as being diagnosed with ADHD can have an impact on how you are treated, researcher Ebba de Ritz says in a press release.
“[It]can benefit patients’ long-term health and quality of life,” she says.
The increased risk can be explained to some extent by genetic factors that contributed to both ADHD and ADHD, with a few exceptions.
People with ADHD are often treated with central stimulants.
“The results are important because treatment with stimulants requires close monitoring in comorbid heart disease, hypertension and liver failure,” study co-author Henrik Larsson, professor at the University of Örebro and associate researcher at Karolinska Institutet, says in a press release.
The study was published in the scientific journal Lancet Psychiatry.
