Cognition Disorders In Old Age

The goal of this clinical trial is to learn if two food supplements based on olive leaf extract, alone or combined with mullein extract, help maintain cognitive function in older adults with mild cognitive impairment (MCI). It will also evaluate their safety. The main questions it aims to answer are: Do the supplements improve or help maintain cognitive function (such as memory and attention)? Do participants experience any side effects when taking the supplements? Researchers will compare two active supplements to a placebo (a look-alike substance with no active ingredients) to see if the supplements are effective. Participants will: Take either one of the two supplements or a placebo every day for 6 months Take 2 capsules per day, preferably between meals, with a small amount of water Visit the clinic at the start of the study, after 3 months, and after 6 months for cognitive assessments Complete questionnaires to evaluate cognitive function and quality of life Be monitored throughout the study for any side effects

TRACOMDD study is a study with the intention to describe the real-world use of trazodone and the clinical response in a sub-group of patients affected by Major Depressive Disorder and Mild Cognitive impairment, by collecting data from standard clinical practice in Italy, Poland, and Romania

This study aims to evaluate the effect of L-arginine supplementation on cognitive function in geriatric patients. Eligible participants will receive either L-arginine (6 grams once daily) or placebo, and their cognitive performance will be assessed using validated cognitive assessment tools over the study period. The participants will receive the intervention for 4 weeks and followed up every 2 weeks. The primary outcome is improvement in cognitive function, while secondary outcomes include safety, tolerability, and quality of life measures. The findings may provide evidence for the potential role of L-arginine in supporting cognitive health in elderly populations.

The goal of this study ifs to determine the comparative effects of Lee Silverman voice treatment Big and dual task training on balance, cognition and functional mobility in older adults with cognitive impairment. Perform LSVT big four times in a week for about 4 months. Perform dual task training four times in a week for about 4 months. Complete assessments at baseline, the 4th, 8th, 12th weeks, and a follow-up at the 16th week. Outcome measures include Mini BESTest, MoCA, stroop test and time up and go test. Statistical analyses will assess within-group and between-group effects based on data distribution.

Neuropsychological tests currently considered to evaluate the cognitive performance of the oldest-old population (more than 80 years) are not adapted to this group population. This trial aims to determine the normal limits for this group population of a set of 18 neuropsychological test. Results may improve the diagnostic cognitive evaluation of this population.

The main objective is to investigate whether administration of probiotics to patients with mild Alzheimer's Disease (AD) reduces neuroinflammation, improves cognitive function and modifies neurophysiological measures, compared to a patient group that receives placebo (no active probiotics).

Electrical activity in the brain known as "gamma" brainwaves help connect and process information throughout the brain. These gamma waves are diminished in Alzheimer's disease. New research in Alzheimer's disease mouse models shows that exposure to light flickering at the rate of 40 flashes per second or 40Hz increased gamma brainwaves and led to clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease. This project will test the ability of a novel iPad App (AlzLife https://www.alz.life/) that delivers light therapy at 40 Hz combined with cognitive therapy to improve cognition, function, and quality of life in Alzheimer's disease.

The Interventions for Brain Health Virtual Reality Study is a NIH-funded clinical research trial at the University of California San Diego (UCSD) Health under the supervision of the study principal investigator Dr. Judy Pa. The overarching goal of this trial is to use a novel virtual reality (VR) based intervention that simultaneously engages physical and cognitive activity aimed at improving brain health and cognition in older adults. The investigators will compare 3 types of interventions: physical activity, VR cognitive activity, and combined VR physical and cognitive activity over 16 weeks to evaluate physical and brain health changes.

The current project is dedicated to creating a comprehensive cognitive and neural assessment platform and corresponding norms tailored specifically to the older adults in Macau.
