Children with hyperthyroidism have a higher prevalence of attention-deficit/hyperactivity disorder (ADHD), adjustment disorder, anxiety, bipolar disorder, depression and suicidality, according to a new study published online in Pediatrics. Researchers determined the prevalence of hyperthyroidism and mental-health conditions (MHCs) using data from the Military Health System Data Repository on military beneficiaries between 10 and 18 years old.

They identified 1,894 females and 585 males with a diagnosis of hyperthyroidism during the study period (2008-2016). Compared with children without hyperthyroidism, the prevalence ratios of MHCs in children with hyperthyroidism ranged from 1.7 (ADHD) to 4.9 (bipolar disorder), with all risk increases being statistically significant.
