Aside from dietary intake, the only source of choline in the body is de novo synthesis of phosphatidylcholine, catalyzed by phosphatdylethanolamine-N-methyltransferase (PEMT). The PEMT gene has several estrogen-responsive components in its promoter region and is induced by estrogen. Post-menopausal (hypo-estrogenic) women with loss of function mutations in PEMT have been found to exhibit end-organ damage typical of choline deficiency.\n\nCholine is also involved in the synthesis of acetylcholine, a major neurotransmitter and the central and peripheral nervous systems. The relationship between brain effects of the normal functioning of the cholinergic system and hormone changes after menopause has been demonstrated in preclinical studies in rat models and in experimentally in human studies. While the preclinical and clinical experiment studies have many similar findings regarding the influence of estrogen on cholinergic functioning, what is not clear from this research is how individual differences arise in the effects of the hormone withdrawal after menopause on brain functioning in middle aged women. It is possible that the estrogen control of the transcription of the PEMT gene may influence the availability of choline.\n\nThis study will examine the effects of a single oral dose of oral dose of 1650 mg choline versus placebo in 20 healthy postmenopausal women aged 50-65 years. Choline or placebo will be administered three hours before an MRI session where subjects undergo functional MRI scans.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '50 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Women aged 50-65 years\n* Postmenopausal: Women who are postmenopausal will have not had a period in the last 12 months, have FSH\\>30 IU/L, and estradiol (E2) \\<50 pg/ml.\n* Nonsmokers\n* Not taking hormone therapy, SSRIs, phytoestrogens, SERMS, or antiestrogen medications and will be at least one year without such treatment\n* Physically healthy\n* No cardiovascular disease other than mild hypertension.
