The Effect of Dietary Strawberry Supplementation on Older Adults
AgingAge-related Memory DisordersThis study is being conducted to assess the effect of dietary strawberry supplementation on cognition and mobility in older adults. It is hypothesized that plant compounds, present in strawberries, may improve cognition and mobility by protecting against oxidative stress and inflammation.

Efficacy and Safety of Piracetam Taken for 12 Months in Subjects Suffering From Mild Cognitive Impairment...
Memory DisordersThe purpose of this study was to explore in a more documented way the relative potential and efficacy of piracetam 9600 and 4800 mg daily.
Study of LX6171 in Elderly Volunteers With Age Associated Memory Impairment
Age-Related Memory DisordersThe purpose of the study is to determine the safety, tolerability, and effectiveness of 2 dose levels of LX6171 given over 28 days in patients with Age Associated Memory Impairment (AAMI).
Efficacy of Repetitive Transcranial Magnetic Stimulation for Improvement of Memory in Older Adults...
Brain InjuriesTraumatic3 moreThe proposed study will evaluate the safety, durability and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a promising non-invasive therapeutic treatment for improving memory in older adults with mild or moderate Traumatic Brain Injury (TBI) who have been experiencing residual memory or cognitive problems that affect daily functioning.
Neuropsychological Rehabilitation of Spontaneous Confabulation: a Replica Study
Memory DisordersConfabulators consistently generate false memories without intention to deceive and with great feeling of rightness. However, there is currently no known effective treatment for them. In order to fill this gap, we performed a neuropsychological treatment in two groups of confabulators: experimental vs. control (ClinicalTrials.gov ID: NCT02540772). Now, we intend to replicate the treatment with a larger sample of confabulators and with other two control groups: non-confabulator patients with brain injury and healthy individuals
Noninvasive Brain Stimulation for Mild Cognitive Impairment
Mild Cognitive ImpairmentMild Neurocognitive Disorder6 moreThe goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one of three treatment groups: Group 1: Active Dorsolateral Prefrontal Cortex (DLPFC) rTMS; Group 2: Active Lateral Parietal Cortex (LPC) rTMS; and Group 3: Inactive rTMS (Placebo) control (evenly split between each coil location). Participation in the study takes approximately 7 ½ months-including a 2-to 4-week treatment phase (20 rTMS sessions) and a 6-month follow-up phase.
Prehabilitation Exercise Plus Perioperative Optimization of Senior Health
Cognitive DeclineAge-Related Memory Disorders3 moreThe purpose of this study is the examine the feasibility of and estimate the efficacy of a preoperative exercise (i.e. prehabilitation) program in 40 up to sedentary older adults (i.e. age 60 and over) undergoing abdominal, urologic or gynecologic surgery under the Enhanced Recovery After Surgery (ERAS) protocol at Duke, using a variety of techniques to measure the possible effect of this intervention. Study patients will undergo a program of prehabilitation exercise for 6 days per week prescribed for them by an exercise physiologist, for up to 4 weeks prior to surgery. Study participants will undergo four types of assessments: Functional/Cognitive testing; Blood/cerebrospinal fluid (CSF) samples and Muscle biopsies; Brain Imaging; and Brain Activity Recording. Clinical Outcomes will also be obtained from the Duke electronic medical record system. The risks of the exercise intervention are generally mild, since moderate exercise in this patient population generally results in improved health outcomes. Data from these patients will be analyzed in comparison to propensity matched patients from the Duke Markers of Alzheimer's Disease and neurocognitive Outcomes after Perioperative Care (MADCO-PC) study who did not undergo this prehabilitation exercise intervention. Taken together, the results of this study will allow the investigators to estimate the possible effect of prehabilitation exercise on multiple domains of postoperative recovery (cognition, brain connectivity, biomarkers, brain activity, etc) and will provide important preliminary data.
tACS Improves Memory in Elders With Subjective Memory Complaints
Memory DeficitstACSSubjective memory complaints (SMC), the main cognitive component of which is event memory, is a predictor of Alzheimer's disease in elderly people. The purpose of this study was to investigate the effect of transcranial alternating current stimulation (tACS) with theta frequency (6 Hz) on the medial prefrontal cortex in the improvement of episodic memory in individuals with SMC in a double blind, randomized, and sham-controlled parallel study. Sixteen participants with SMC received either active or sham theta tACS on the medial prefrontal cortex (mPFC). EEG was recorded and Rey Auditory Verbal Learning Test (RAVLT) was administered. The aim of the current study was to see if theta tACS over the mPFC can improve event memory in individuals with SMC and thus can be considered a potential therapeutic intervention for this population or not.
Couples Health Aging, Rhythms and Sleep Study
AgingMemory LossAlzheimer's disease and related dementias (ADRD), including mild cognitive impairment (MCI), are becoming among the most prevalent causes of disability, death and healthcare costs worldwide. Sleep and circadian rhythm disturbances are common among individuals with MCI as well as their spouses/ partners and may increase risk of the development of ADRD in both patients and partners. This is the first study to systematically investigate sleep as a shared health behavior within couples in which one member has MCI, and the degree to which sleep and circadian disturbances impact both partners health and well-being, including cognitive decline and risk for ADRD.
