Filter by:This is an open label feasibility trial to learn whether the combination of donepezil and cognitive remediation therapy (Donepezil + CRT) may improve neurocognitive functioning and decreasing alcohol use in Veterans with alcohol use disorder who have mild cognitive impairment (AUD-MCI). The study will determine the acceptability and adherence to treatment and preliminary evidence for efficacy. The study will recruit 15 newly recovering Veterans individuals with AUD-MCI for a 13-week, open-label, single-arm pilot study with sobriety and cognitive assessments at baseline and at 13-week follow-up.
The aim of the current study is to investigate whether daily intake of Nordic berries for 12 weeks can improve cognitive abilities of adults with mild cognitive impairment, and whether the effect can be linked to changes in metabolic parameters.
Postoperative neurocognitive disorders, including postoperative delirium (POD) and postoperaive cognitive dysfunction (POCD), are common complications of perioperative neurocognition in elderly patients undergoing surgery. POD and POCD have short- and long-term consequences, such as increased hospital stays and costs, augmented morbidity and mortality, as well as higher risk for cognitive decline later in life. Therefore, early prevention and diagnosis of these conditions is of great importance. A number of psychometric tests have been proposed as cognitive screening tools. Given the fact that many of them show weaknesses and difficulties in performance, scientists have sought for more useful alternatives. Montreal Cognitive Assessment (MoCA) is considered to be a good choice, as it has been successfully applied in the perioperative setting. What's more, it has been translated and validated for a Greek population with neurological disorders. Addenbrooke's Congnitive Examination III (ACE III) has been introduced recently into clinical practice. It is an easy to perform and detailed test that covers several neurocognitive domains and has shown high sensitivity and specificity in clinical conditions, including dementia and Alzheimer's disease. Although current literature lacks data concerning its perioperative use, ACE III could prove useful for screening patients undergoing surgery and anesthesia on the basis of its favorable characteristics as mentioned above. The aim of this study is to translate the ACE III (English version 2012) into Greek and assess its validity in perioperative patients aged >55 years.
The goal of this study is to test efficacy and safety of person-centered, culturally-informed protocols for disclosure of different combinations of Alzheimer's dementia risk factors. Building on the results from a federally-funded assessment of preferences and needs of racially diverse participants and their respective friends/family members, in regard to Dementia - Alzheimer's Type (DAT), we have produced protocols for communication of DAT risk, with attention to specific adaptations in style or content based on individual factors and preferences. These protocols allow for communication of risk based on clinical history and diagnosis, structural neuroimaging, apolipoprotein-E status, and amyloid and tau burden on positron emission tomography. In particular, protocols specify (a) effective methods of communicating risk conferred by each data source, (b) information designed for patients versus informants, (c) psychoeducation needs, and (d) resource/support needs. We will recruit a randomly-selected subset of 10 dyads (including 5 participants who are Non-Hispanic African-American, 5 participants who are Non-Hispanic White) from the Stage I sample to whom we will develop and implement personalized DAT risk disclosure protocols. We will provide preliminary information on the effectiveness of these protocols in terms of patient/co-participant comprehension and recall of feedback provided, and initial changes in mood or behavior immediately following and shortly after risk disclosure sessions.
The aim is to develop and validate a new brief and accurate case-finding instrument for dementia and cognitive impairment - BASIC
The aim of this study is to compare the effects of single and dual-task training on processing speed, cognitive functions, walking speed, dual-task performance and balance functions in individuals with mild cognitive impairment.
Brucellosis is a common zoonotic infection in many parts of the world including the Mediterranean and Middle Eastern countries. Neurobrucellosis may develop at any stage of disease and may have widely variable manifestations, including encephalitis, meningoencephalitis, radiculitis, myelitis, peripheral and cranial neuropathies, subarachnoid hemorrhage, and psychiatric manifestations.
FINOMAIN is a community-based, cluster randomized controlled trial (cRCT) of dance intervention INDAK and standardized vascular care. The study aims to develop and assess the effectiveness of a cost-effective and culturally - fit intervention for Filipino older adults at high risk for developing dementia. The first objective of the study is to evaluate the efficacy of dance intervention INDAK on cognitive function as assessed by the Alzheimer's Disease Assessment Scale - Cognitive (ADAS-Cog), Mnemonic Similarity Task (MST), and Executive Function Composite (EFC) among older adults with mild cognitive impairment (MCI). To increase the sensitivity of primary outcome for various composites of cognition, aside from ADAS-Cog that assesses core cognitive deficits of dementia, investigators will develop an executive function composite that will combine measures of executive control using performance outcomes on tests including Trail Making Test (TMT), Digit Symbol Substitution Test (DSST), Verbal Fluency Test (VFT), and Number Cancellation Task (NCT). Executive function composite scores have been used to track aging populations at risk for dementia and are shown to be sensitive in capturing cerebrovascular benefits and used as instruments in studies with similar non-pharmacological intervention (i.e. aerobic exercise, dance). Additionally, the investigators will add MST which is a measure for episodic memory, memory representations and pattern discrimination which are all cognitive domains highly correlated with hippocampal function. The second objective of the study is to determine the effect of dance on neuroplasticity as measured by brain volumetry and functional connectivity demonstrated through Magnetic Resonance Imaging (MRI) and change in other behavioral and functional outcomes of participants with MCI.
Qi Zhi Tong Luo (QZTL) capsule, a traditional Chinese herbal medicine, which was used to treat stoke-related symptoms, include trouble speaking, paralysis and trouble walking. This study aimed to evaluate the efficacy and safety of QZTL capsule in the treatment of vascular cognitive impairment. This study was designed as randomized, double-blind, parallel, placebo-controlled, multicentre trial. It consisted of a single-blind run-in period using placebo only (2 weeks) and a double-blind treatment phase after randomization (24 weeks), and follow-up 12 weeks after withdrawal.The primary efficacy variables included changes from baseline in the Clinical Dementia Rating scale-Sum Box (CDR-SB) and the Mini-mental State Examination (MMSE) after 24 weeks of treatment. The secondary efficacy measurements include the Clock Drawing Test (CDT), Hopkins Verbal Learning Test (HVLT) and Ability of Daily Living (ADL).
Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective pharmacologic therapy for this disease. Electroencephalogram-based neurofeedback is considered as a potentially treatment strategy. In this project, the investigators aim to investigate the effectiveness of neurofeedback therapy on cognition for individuals with subjective cognitive decline (SCD). Participants will receive electroencephalogram-based neurofeedback therapy once a day for successive five days. Then, the investigators will evaluate the changes of memory function between baseline and post-therapy visits.
