It will also learn about the feasibility of practicing 14 h of nightly fasting in this group of older adults. The main questions it aims to answer are:\n\n* Does prolonged nightly fasting of 14 h can reduce markers of AD pathology and aging and reduce cognitive and sleep alterations in MCI and AD patients?\n* Can patients with MCI and early \u002Fmoderate AD sustain time-restricted eating for 3 to 6 months? Researchers will compare participants who fast for 14 h per night during 3 months to those who fast for less than 12 h\u002Fnight. Researchers will also compare participants that fast for 3 months to those who fast during 6 months, to determine the effective duration of the intervention. Finally, researchers will evaluate whether following the time-restricted eating diet alongside a partner actively following the same diet, will increase adherence to the protocol compared to subjects that fast alone.\n\nParticipants will:\n\n* Fast for 14 h a night (stop eating at 8 pm and start eating the following morning at 10 am) for 3 or 6 months\n* Visit the clinic three times (at the beginning of the study, 6 and 12 months later)\n* Provide blood samples and take a cognitive test during clinic visits\n* Keep a diary (or use an app on a smart phone) to record time of eating\n* Wear an activity tracker watch",[85,86,87],"Mild Cognitive Impairment","Alzheimer Disease","Alzheimer's Disease",[89,90,25,85,86,91,92,93],"Time-Restricted Eating","Intermittent Fasting","Circadian Rhythms","Cognition","Neuropathology","2026-05-21",{"date":96,"type":97},"2026-05-26","ACTUAL",{"date":99,"type":97},"2025-04-23",{"date":101,"type":79},"2027-06-30",{"name":5,"class":6},1]
