brain involved in memory will have an affect on brain activity and whether it may improve memory in people with Mild Cognitive Impairment and Mild Alzheimer's Disease.\n\nThe main questions the study seeks to answer are:\n\n1. Can LIFUP increase brain activity in the targeted area?\n2. Can LIFUP improve memory in people with MCI and mild AD?\n3. Can LIFUP improve connectivity of memory networks in the brain?\n\nParticipants in this study will complete MRIs and memory testing, and receive Low Intensity Focused Ultrasound to a part of their brain involved in memory (the entorhinal cortex).",[98,99,100,101],"Mild Cognitive Impairment","Amnestic Mild Cognitive Disorder","Deep Brain Stimulation","Mild Alzheimer's Disease",[103,104,105,106,107,108,109,110,111,112,113],"deep brain stimulation (DBS)","transcranial focused ultrasound stimulation (tFUS)","memory","low-intensity focused ultrasound pulsation (LIFUP)","fMRI","mild cognitive impairment","mci","noninvasive brain stimulation (NIBS)","ultrasound","Alzheimer's Disease","Mild Alzheimer's","2026-04-13",{"date":116,"type":117},"2026-04-16","ACTUAL",{"date":119,"type":117},"2022-09-01",{"date":121,"type":92},"2026-07-31",{"name":5,"class":6},1]
