The development of new therapies has primarily focused on preventing the progression of AD. This therapeutic strategy involves being interested in patients with an early stage of AD such as a mild cognitive impairment (MCI). We hypothesized that the combination of Lecitone®Se with 200 IU/day of vitamin D can slow or even improve cognitive decline, particularly executive functions.\n\nThe primary objective of this trial is to compare the effect after 12 weeks of the oral intake of Lecitone®Se-Vitamin D3 with the effect of a placebo on changes in performance obtained in the TMT B in the older adults with a MCI.\n\nThe secondary objectives of the study are as follows:\n\n* To compare the effect after 12 weeks of the oral intake of Lecitone®Se-Vitamin D3 with the effect of a placebo on changes in executive performance in patients with a MCI.\n* To compare the effect after 12 weeks of the oral intake of Lecitone®Se-Vitamin D3 with the effect of a placebo on changes in variability of stride time in patients with a MCI.\n* To compare the effect after 24 weeks of the oral intake of Lecitone®Se-Vitamin D3 with the effect of a placebo and a delay phase of supplementation on changes in executive performance in patients with a MCI.\n* To compare the effect after 24 weeks of the oral intake of Lecitone®Se-Vitamin D3 with the effect of a placebo and a delay phase of supplementation on changes in variability of stride time in patients with a MCI.\n* To determine the compliance and tolerance of the oral intake of Lecitone®Se-Vitamin D3 in patients with a MCI."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '60 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age ≥ 60 years\n* Memory complaints\n* No dementia (DSM-IV, NINCDS-ADRDA negative)\n* No depression (Geriatric Depression score ≤ 5/15)\n* Ability to walk a distance of 15 meters unaided\n* Diagnosis of MCI\n* To have hypovitaminosis D (i.e. serum 25-hydroxyvitamin D \\[25OHD\\]concentration ≤ 30ng/mL)\n* To have no hypercalcemia (defined as serum calcium concentration ≥ 2,65mmol/L)\n* To have given and signed an informed consent to participate in the trial\n* To be affiliated to French Social Security\n\nExclusion Criteria:\n\n* Others cognitive disorders (untreated thyroid dysfunction, chronic ongoing ethylism, history of syphilis, stroke, severe depressive symptomatology (Geriatric Depression score \\> 5/15), existence of dementia according to DSM-IV and NINCDS-ADRDA criteria at the time of inclusion)\n* Vitamin D supplementation during inclusion\n* Contraindications to vitamin D\n* Unstable medical condition\n* Enrollment in another simultaneous clinical trial\n* Civil defense measures underway'}, 'identificationModule': {'nctId': 'NCT01708005', 'acronym': 'DIET-D', 'briefTitle': 'DIetary Supplements, Executive funcTions and Vitamin D (DIET-D)', 'organization': {'class': 'OTHER_GOV', 'fullName': 'University Hospital, Angers'}, 'officialTitle': 'DIetary Supplements, Executive funcTions and Vitamin D (DIET-D): a Double-blind Randomized Controlled Trial', 'orgStudyIdInfo': {'id': '2012-A00453-40'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Intervention', 'description': '80 participants start the oral intake of Lecitone®Se-Vitamin D3 the day after inclusion and during 24 weeks', 'interventionNames': ['Drug: Lecitone®Se-Vitamin D3']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': '80 participants in this arm start the oral intake of placebo the day after inclusion and during 12 weeks.\n\nThen, they start the oral intake of Lecitone®Se-Vitamin D3 12 weeks after inclusion until the 24th week.', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'Lecitone®Se-Vitamin D3', 'type': 'DRUG', 'description': 'Lecitone®Se-Vitamin D3 is a dietary supplement combining the active ingredients in Lecitone®Se and 100 IU of vitamin D3.
