The aim of this study was to evaluate relationships between emotional state and hypothalamic activity in patients with hypothalamic secondary amenorrhea. Sixty-seven normal weight patients with hypothalamic amenorrhea were submitted to concomitant psychological and LH pulsatility evaluation. Structured clinical interview for anxiety and depressive disorders (DSM III-R) as well as life events investigations (Paykel test) were performed. LH pulses (blood sampling every 10 min for 4 hr) were analyzed through DETECT program and Instantaneous Secretory Rate were computed. Twenty-one patients reporting life events associated to the onset of amenorrhea had LH pulse frequency (2.28 +/- 1.10 pulses/4 hr) lower than those without life events (3.40 +/- 1.46 p = .007). LH pulses amplitude was lower in patients meeting a DSM III-R (21 cases: 1.22 +/- 0.96 mIU/ml) diagnosis than in those without (1.99 +/- 1.20 p = .04) diagnosis. Plasma estradiol and FSH levels as well as duration of amenorrhea and Body Mass Index were similar among groups. It is concluded that psychogenic factors (namely the presence of life events related to the onset of menstrual disorder) are associated with significant and specific changes of hypothalamic activity which could be involved in determining hypogonadism.

Abstract

The aim of this study was to evaluate relationships between emotional state and hypothalamic activity in patients with hypothalamic secondary amenorrhea. Sixty-seven normal weight patients with hypothalamic amenorrhea were submitted to concomitant psychological and LH pulsatility evaluation. Structured clinical interview for anxiety and depressive disorders (DSM III-R) as well as life events investigations (Paykel test) were performed. LH pulses (blood sampling every 10 min for 4 hr) were analyzed through DETECT program and Instantaneous Secretory Rate were computed. Twenty-one patients reporting life events associated to the onset of amenorrhea had LH pulse frequency (2.28 +/- 1.10 pulses/4 hr) lower than those without life events (3.40 +/- 1.46 p = .007). LH pulses amplitude was lower in patients meeting a DSM III-R (21 cases: 1.22 +/- 0.96 mIU/ml) diagnosis than in those without (1.99 +/- 1.20 p = .04) diagnosis. Plasma estradiol and FSH levels as well as duration of amenorrhea and Body Mass Index were similar among groups. It is concluded that psychogenic factors (namely the presence of life events related to the onset of menstrual disorder) are associated with significant and specific changes of hypothalamic activity which could be involved in determining hypogonadism.
