Some research has suggested that low [[Thalamus|thalamic]] iron levels may play a role in the pathophysiology of [[Attention deficit hyperactivity disorder|ADHD]].<ref>{{cite journal |last1=Robberecht |first1=Harry |display-authors=etal |title=Magnesium, Iron, Zinc, Copper and Selenium Status in Attention-Deficit/Hyperactivity Disorder (ADHD) |journal=Molecules |year=2020 |volume=25 |issue=19 |page=4440 |doi=10.3390/molecules25194440 |pmid=32992575 |pmc=7583976|doi-access=free }}</ref> Some researchers have found that iron supplementation can be effective especially in the [[Attention deficit hyperactivity disorder predominantly inattentive|inattentive subtype]] of the disorder.<ref>{{cite journal |last1=Soto-Insuga |first1=V |display-authors=etal |title=[Role of iron in the treatment of attention deficit-hyperactivity disorder] |journal=An Pediatr (Barc) |date=2013 |volume=79 |issue=4 |pages=230–235 |doi=10.1016/j.anpedi.2013.02.008 |pmid=23582950}}</ref>

Some researchers in the 2000s suggested a link between low levels of iron in the blood and ADHD. A 2012 study found no such correlation.<ref>{{Cite journal |last1=Donfrancesco |first1=Renato |last2=Parisi |first2=Pasquale |last3=Vanacore |first3=Nicola |last4=Martines |first4=Francesca |last5=Sargentini |first5=Vittorio |last6=Cortese |first6=Samuele |date=May 2013 |title=Iron and ADHD: Time to Move Beyond Serum Ferritin Levels |journal=Journal of Attention Disorders |language=en |volume=17 |issue=4 |pages=347–357 |doi=10.1177/1087054711430712 |pmid=22290693 |s2cid=22445593 |issn=1087-0547}}</ref>
