Filter by:This study will use an anticholinergic pharmacological probe to examine attention network function in SCD using EEG. The overall hypothesis is that in older adults with SCD, normal cognitive performance is maintained by compensatory attention network activity, supported by enhanced cholinergic function. The investigators anticipate that SCD will be associated with greater compensatory attention network activity and that disrupting this compensatory process through anticholinergic challenge will result in a greater negative effect on attentional performance (Attention Network Test, ANT) and attention network functioning (EEG) in older adults with greater subjective cognitive concern.
The purpose of this study is to determining the feasibility of providing the Memory Support System (MSS) to individuals with mild cognitive impairment (MCI) and their partners at a clinic in Ontario, Canada. This will involve a) collecting information from patients referred to the a memory clinic and geriatric day hospital about their interest in and their preferred method to administer the MSS; and b) a cost analysis related to implementation of the MSS. The study will also measure efficacy outcomes of the MSS regarding program adherence as well as to self-reported IADLs, self-efficacy for memory, quality of life, mood, anxiety, and caregiver burden among a sample of individuals with MCI and their care partners
The Effects of Successful OSA TreatmENT on Memory and AD BIomarkers in Older AduLts (ESSENTIAL) study is a 5-year, multicenter randomized open-label trial that will screen 400 cognitively normal older adults recruited from well-established sleep clinics at 4 academic medical centers, with newly diagnosed moderate-severe OSA. An expected 200 OSA patients will be then randomized to one of two groups: i) a 3-month OSA treatment by any combination of PAP, OAT, and positional therapy that results in an "effective" AHI4%< 10/hour and AHI3A<20/hour (see below); ii) a waitlist control group to receive treatment at the conclusion of the 3-month intervention period. Both groups will continue follow-up for 24 months on stable therapy to determine if sustained improvements in sleep are associated with improvement in cognitive function and AD biomarkers.
This protocol focuses on the effect of sleep interventions on improving sleep and building cognitive/brain resilience in older adults with amnestic mild cognitive impairment and sleep disturbance. Two sleep interventions, cognitive behavioral therapy for insomnia (CBTI) and acoustic slow-wave activity enhancement (SWAE), will be utilized in a pilot randomized clinical trial in which participants are randomized to different treatment groups (CBTI or SWAE). Participants will be assessed over a 6-month period in order to examine the impact of sleep treatments on neuropsychological outcomes and cognitively mediated everyday functioning.
The primary objective of the study is to evaluate the efficacy of AGB101 on slowing cognitive and functional impairment as measured by reduction in neuronal injury in participants with mild cognitive impairment due to Alzheimer's Disease. Participants will be randomized to receive placebo or AGB101 (220 mg), once daily for 78 weeks. Secondary objectives are to assess the effect of AGB101 compared with placebo on clinical progression as measured by the Clinical Dementia Rating Scale- Sum of Boxes and Memory Box score.
The objective of this clinical trial is to explore the efficacy of menopausal hormone therapy in early menopausal women with CSVD and MCI. The main questions it aims to answer are: - The efficacy of menopausal hormone mainly estrogen therapy for early menopausal women with CSVD and MCI - The role of MHT in delaying the progression of cognitive function, CSVD imaging features, and other clinical symptoms and the potential pathophysiological mechanisms. Participants will be divided randomly into two groups taking MHT drugs and placebo respectively and followed up for 12 months to collect relevant clinical data.
Dementias secondary to cerebrovascular diseases are of significant epidemiological and clinical relevance. As a result, the management of individuals with comorbid dementia should involve early diagnosis, effective treatment, and patient-centered care planning, both in specialist and in non-specialist settings. It is well known that physical exercise can improve various aspects of health, including resistance, balance, strength, and cognitive functions such as attention and executive performance. However, the efficacy of cognitive rehabilitation is still not definitive and requires further clarification. Preliminary evidence suggests that a combination of cognitive and motor training along with novel technological approaches has the potential to maintain or improve compromised cognitive function more effectively compared to a single intervention. A multidomain intervention could enhance cognitive functioning in elderly individuals with multiple morbidities. In the present study, patients with early neurocognitive impairment based on a vascular disorder or due to multiple etiologies, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, will be screened in an outpatient multidisciplinary setting and subsequently undergo different models of rehabilitation training. Primary aim of this study: - Assess the effectiveness of different rehabilitation protocols for improving cognitive functions in patients with comorbid cognitive impairment. Specifically, the investigators will test the effectiveness of three rehabilitation protocols (digital-based cognitive rehabilitation combined with motor rehabilitation, paper-based cognitive rehabilitation combined with motor rehabilitation, and motor rehabilitation alone) by means of a set of multidimensional outcome measures. Secondary aims: - evaluating the enhancement of cognitive performance using various cognitive questionnaires categorized by cognitive domains. Additionally, the investigators will examine multidimensional variables such as motor skills, mood and anxiety levels, quality of life, patient adherence to treatment, the role of communication in patient management, caregiver burden, and the usability of digital devices (when utilized).
The study, identified as VIX001-PACS-01, is a Phase 1, open-label, dose-escalation trial evaluating the safety, tolerability, preliminary efficacy, and dose effect of VIX001, an amniotic fluid product, in patients with Post-Acute COVID-19 Syndrome (PACS) and cognitive impairment. Conducted at the University of Miami Hospital and Clinics, the trial aims to enroll up to nine participants, or up to 18 using a 3+3 dose escalation design. Intravenous injections of VIX001 will be administered at three ascending doses (1 ml, 3 ml, or 10 ml), and participants will be assessed for safety, cognitive impairment, pain, activity, and quality of life at baseline and various timepoints. The primary objective is to evaluate the safety of VIX001, while secondary objectives include assessing its potential efficacy and patient-reported outcomes. The study duration is expected to last approximately 18 months, including enrollment, evaluation, and post-study observation periods. The findings will contribute to understanding VIX001's safety and efficacy in treating PACS-related cognitive impairment.
Cognitive impairment has been reported up to 54 % after colorectal surgeries. Mechanical bowel cleansing means that a system called the second brain in the body, which includes a wide variety of genetic and neuronal structures, is damaged. 100 trillion microorganisms live in the human body. The largest contact area with the external environment in the body, is the gastrointestinal mucosa. Microorganisms in the gut contain 100 times more genes than the human genome. The GI mucosa contains more than 500 million neurons called the enteric nervous system. MBP is an application that disrupts the microbiota structure and causes dehydration and electrolyte imbalance. While the most serious indication for MBP is seen as infection and health of anastomosis, recent studies say that this is not the case, even that the deterioration of the microbiota content damages the mucosal barrier, predisposes to inflammation with the removal of beneficial microorganisms and impairs wound healing. 84 patients will be included in the study, divided into two groups. In each group, blood will be drawn to measure the levels of biomarkers determined before surgery and bowel cleansing, on the 15th postoperative day and on the 90th day. Simultaneously, psychometric tests will be performed to assess cognitive impairment.
The objective of this trial is to evaluate the effect of electroacupuncture compared to sham acupuncture in preventing CRCI among breast cancer patients scheduled to undergo chemotherapy.
