Study links adrenal gland tumors to ADHD

Pediatric patients diagnosed with pheochromocytomas (PHEO) or paragangliomas (PGL) were nearly three times as likely to also carry a diagnosis of attention deficit hyperactivity disorder (ADHD), compared to pediatric patients without PHEO or PGL. A study in Hormone and Metabolic Research reported May 12, 2016 found a prevalence of ADHD in 21% of PHEO/PGL patients, significantly higher than 7.2% seen in the general pediatric population. And, in 33% of the patients with PHEO and PGL, ADHD symptoms were resolved following surgical removal of the tumor.
