Endocrine profiles and neuropsychologic correlates of functional hypothalamic amenorrhea in adolescents.

OBJECTIVE

To determine trigger factors and neuropsychologic correlates of functional hypothalamic amenorrhea (FHA) in adolescence and to evaluate the correlations with the endocrine-metabolic profile.

DESIGN

Cross-sectional comparison of adolescents with FHA and eumenorrheic controls

SETTING

Academic medical institution

PATIENT(S): Twenty adolescent girls with FHA (aged <18 years) and 20 normal cycling girls

INTERVENTION(S): All subjects underwent endocrine-gynecologic (hormone) and neuropsychiatric (tests and interview) investigations. A separate semistructured interview was also used to investigate parents.

MAIN OUTCOME MEASURE(S): Gonadotropins, leptin, prolactin, androgens, estrogens, cortisol, carrier proteins (SHBG, insulin-like growth factor-binding protein 1), and metabolic parameters (insulin, insulin-like growth factor 1, thyroid hormones) were assayed in FHA and control subjects. All girls were evaluated using a test for depression, a test for disordered eating, and a psychodynamic semistructured interview.

RESULT(S): Adolescents with FHA showed a particular susceptibility to common life events, restrictive disordered eating, depressive traits, and psychosomatic disorders. The endocrine-metabolic profile was strictly correlated to the severity of the psychopathology.

CONCLUSION(S): Functional hypothalamic amenorrhea in adolescence is due to a particular neuropsychologic vulnerability to stress, probably related to familial relationship styles, expressed by a proportional endocrine impairment.
