Studies Find Link Between ADHD, Fibromyalgia

Various studies have found a link between fibromyalgia and ADHD, with some urging clinicians to evaluate the presence of attention deficit hyperactivity disorder (ADHD) in individuals who have a history of fibromyalgia. ADHD is a condition characterized by persistent impulsivity, hyperactivity, impaired concentration and inattention, as well as disorganized behavior, anxiety and emotional instability. The CDC estimates that while more than 8% of children have been diagnosed with this condition thus far, less than 1% of adults have received the same consideration.

Fibromyalgia is a chronic pain disorder linked to modified activity of the neurotransmitters involved in pain sensitivity, with deficits in concentration, attention and memory. Figures from the CDC show that this chronic disorder affects approximately 4 million individuals in America, which makes up about 2% of the country’s adult population.

The lead author of a previous study that focused on this link, Sebastián Moyano, stated that his group had noticed a high prevalence of adult and childhood ADHD among fibromyalgia patients. Moyano noted that most of these patients hadn’t been diagnosed with ADHD as children. His preliminary study was conducted in 2018 and included 37 patients with fibromyalgia, with more than 70% testing positive for ADHD.

Moyano recently concluded a follow-up study, which involved 71 controls and 60 patients with fibromyalgia. This recent study confirmed his prior findings, with Moyano noting that the researchers also discovered that cognitive impairment was higher in fibromyalgia patients in comparison to the control group. For this study, the researchers assessed memory, language, attention and various aspects of executive function. In the report, Moyano noted that clinicians should ask their fibromyalgia patients about any cognitive symptoms they had experienced and refer their patients to psychiatrists or neurologists if there were any complaints.

He added that he’d also like to see rheumatologists focus more on the ailment’s aspects and work together with psychiatrists and neurologists in their care teams.

Other studies that have produced similar results to Moyano’s study include a 2021 study that screened individuals with fibromyalgia for the presence of ADHD. The researchers found that more than 24% of these fibromyalgia patients had ADHD, which was linked to higher functional impairment and greater symptom severity for fibromyalgia.

A separate study carried out in 2018 by van Rensberg in South Africa also found that chronic neurodevelopmental disorders that impaired an individual’s cognition were linked to dopamine’s function, noting that ADHD could be linked with pain disorders via shared mechanisms.

As more information becomes available about the link between fibromyalgia and other health conditions, the urgency felt by established companies such as Silo Pharma Inc. (OTCQB: SILO) to develop new treatments for fibromyalgia climbs up a notch higher.
