Filter by:This study is designed as a prospective, double-blind, placebo-controlled, randomized parallel-group study that will be completed at the clinical research facility at St. James' Hospital and at Trinity College Dublin, Ireland. A total of 100 amnestic mild cognitive impairment (aMCI) patients will receive a (real or control) non-invasive transcutaneous electrical stimulation procedure. Patients will be assigned to one of four groups. One group will receive active stimulation, while the three groups will be control groups. One groups will be receive sham stimulation (inactive control), while a second group will receive active stimulation and local anesthesia and a third group will stimulate a different nerve (active control; same sensation different nerve). The investigators will include three control groups to verify that the effect is real and location specific and cannot be associated to a sensation effect. The investigators have opted to use a parallel-group design as it is unclear what the carry-over effect and/or wash-out period will be for stimulation. To eliminate subjective bias, all patients and the investigator testing the endpoint measures will be blinded to the type of intervention. The primary outcome, i.e. memory recall, will be determined by a word association task recorded immediately after stimulation, 7 days after stimulation, and 28 days after stimulation. The secondary outcomes is neurophysiological changes determined by resting state EEG, which will be assessed immediately before and after stimulation in the first session. The investigators will conduct this study as follows: 1. Screening aMCI patients. 2. Randomly assigning aMCI patients to one of the four groups. 3. Administering one session active stimulation (n = 25) or control (n = 25 in each of three control group) stimulation paired with a word-association task; administered by research assistant. 4. Behavioral assessments after each of the three blocks of studying the word associations and neural measures immediately after the last session of Behavioral assessments (T0). 5. Behavioral assessments at seven (T1) and 28 (T2) days after stimulation.
The purpose of this study is to determine whether daily treatment with this new treatment approach, called COT would be effective in protecting the memory and brain regions of people who are already showing signs of memory loss.
The study of plasticity processes, in particular, memory, is one of the fundamental directions in anesthesiology. To date, there are different views on the impact of sedation and anesthesia on memory. Memory consolidation is one of the most crucial processes that the anesthesiologist is interested in. Memory consolidation is the mechanism of transferring short-term memory to long-term memory. The investigators suppose that propofol or dexmedetomidine sedation disrupts memory consolidation. In addition, the investigators inquired about the impact of sedation on 'working memory'. Therefore, a better understanding of the influence of anesthesia and sedation on basic memory processes will allow the anesthesiologist to balance the choice of the drug and ensure the patient's safety in the intraoperative period.
This Our Care Wishes- Dementia pilot study is adapting an existing successful online advance care planning platform to the specific needs of persons living with dementia and shared decision-makers (SDMs) and testing the usability and acceptability among nursing home residents and SDMs.
The cognitive impairment of Parkinson's disease is non amnestic, which is characterized by working memory impairment and executive dysfunction. The current drug therapy (such as levodopa, dopamine receptor agonists) and surgical treatment (such as deep brain electrical stimulation, thalamic lesion) not only can not effectively alleviate cognitive impairment, but also may aggravate cognitive and speech behavior abnormalities. This project will explore how dopamine regulates temporal working memory in human research by combining drug intervention, neuroimaging and cognitive tasks.
The purpose of this study is to determine how effective a 6-week exercise program is for improving memory compared to a no-intervention control group, investigate the brain changes that may be responsible for memory improvements, and determine if the memory benefits and brain changes are retained 6 weeks after completing the exercise intervention in people with Idiopathic generalized epilepsy (IGE).
The purpose of this study is to explore the association between BDNF methylation and neurocognitive performance, perceived stress, and well-being in healthy women.
The proposed study will evaluate a new approach to cognitive rehabilitation of mild traumatic brain injury (mTBI) using a brain stimulation technique called transcranial direct current stimulation (tDCS). Specifically, we will investigate how tDCS combined with cognitive training improves deficits to attention and working memory in Active Duty Service Members with a history of mild traumatic brain injury (TBI). Measures of attention-related brain activity, neurocognitive assessments, and self-reported clinical outcomes will be used to determine effects of tDCS vs. sham tDCS when paired with a cognitive training intervention. By doing this study, we hope to find a reliable, noninvasive, and efficient method of treating mild TBI cognitive symptoms.
This interventional, randomised, placebo-controlled and double-blind study aims to evaluate the effect of a dietary supplementation with a blue fish hydrolysate derived from marine by-products, containing peptides and n-3 polyunsaturated fatty acids, on cognitive performance in a healthy older population, between 60 and 73 years old, with lower memory performance.
The purpose of this study (Bio-Hermes) is to develop a blood, digital, and brain amyloid PET scan biomarker database that can be used to determine whether a meaningful relationship exists between digital tests, blood amyloid-beta, p-tau, and neurofilament biomarker levels and amyloid-beta levels identified through brain amyloid PET images. Blood collected will also be genetically sequenced to gain insights about genes and brain amyloid. The Bio-Hermes study will include 1,000 volunteers over the age of 60 screened for Preclinical Alzheimer's Disease, Prodromal AD, or Mild Dementia AD, and includes an endpoint enrollment requirement of 200 participants from underrepresented minority populations.
