Safety of Psychostimulants in Patients with Pituitary Tumors and Delayed Puberty

Critical First Step: Address the Pituitary Tumor

The American College of Endocrinology recommends that before considering psychostimulant therapy, the pituitary adenoma must be properly diagnosed and managed, as this is the root cause of the delayed puberty and represents a more serious threat to morbidity and mortality than untreated ADHD 1, 2
Dedicated pituitary MRI should be obtained to characterize tumor size, extension, and proximity to optic chiasm, as recommended by the Endocrine Society 3, 4
Serum prolactin levels should be measured using age-specific and sex-specific reference ranges, as prolactinomas are the most common pituitary adenoma in children and adolescents, accounting for 32-66% of cases, according to the Pediatric Endocrine Society 2
Visual fields should be assessed if macroadenoma is present, as optic chiasm compression can occur, as recommended by the American Academy of Ophthalmology 2
Evaluation for hypopituitarism, including growth hormone, thyroid function, and cortisol levels, should be performed, as recommended by the Endocrine Society 3, 4

For prolactinomas, cabergoline is first-line therapy and will address both tumor shrinkage and delayed puberty by normalizing prolactin levels, with a resolution of pubertal delay in 60-70% of pediatric patients, according to the European Society of Endocrinology 2, 6
For other adenomas, transsphenoidal surgery is typically required and should be performed at specialist centers, as recommended by the American Association of Neurological Surgeons 1

The clinical algorithm recommends diagnosing and treating pituitary adenoma first, followed by initiation of appropriate pituitary-directed therapy, and then screening for cardiac and psychiatric contraindications, as recommended by the American College of Endocrinology 1, 2, 6

Close monitoring of height and weight is necessary in pediatric patients, as CNS stimulants are associated with temporary slowing of growth rate, according to the Pediatric Endocrine Society 3, 4
Multidisciplinary care involving pediatric endocrinology, neurosurgery, and psychiatry is necessary, as recommended by the American Academy of Pediatrics 1
Pituitary adenomas in children are more aggressive than in adults and require specialist center management, according to the European Society of Endocrinology 1
