Active clinical trials for "Cognitive Dysfunction"

Insomnia symptoms in older adults with mild cognitive impairment represent a significant public health burden in terms of impaired quality of life, risks from untreated insomnia, and risks from pharmaceutical insomnia treatment. To address the limitations in the most effective non-pharmacological treatments for insomnia in older adults with mild cognitive impairment, a randomized pilot study will be conducted to test a brief (4 week), tablet-based, personalized, multicomponent behavioral sleep intervention for insomnia, compared to a sleep education control, in this at-risk group. The findings of the proposed project will inform future, larger scale clinical trials and may provide a novel and innovative way for older adults with mild cognitive impairment to achieve better sleep and health-related quality of life outcomes.

The aim of this study is to investigate whether a tDCS-accompanied intensive cognitive training of working memory leads to performance improvement in individuals with prodromal Alzheimer's disease.

The clinical trial to valuate efficacy and safety of MMH-MAP in the treatment of cognitive disorders in patients with ischemic stroke in the carotid arteries.

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.

This project assessed the feasibility of transcranial alternating current stimulation in the gamma band to lower beta-amyloid load and improve memory performance.

To analyze the effects of a high intensity interval functional training program (HIFT), in the cognitive and functional capacities of Colombian older adults with mild cognitive impairment.

This research aims to evaluate the effect of cognitive stimulation (CS) on the functioning of the prefrontal cortex (PFC), seeking an analysis of both cerebral hemodynamics in neuroplasticity and aspects related to the initiation of neurodegenerative processes. The intervention presents an individual format and the participants are elderly without or with neurocognitive disorders (NCD). Concretely, to assess the effects of individual CS on global cognition, and mood, as well as to analyze neuronal activity with oxygenation, volume and blood flow in the brain, evaluating the impact of cognitive stimulation on brain hemodynamics. Participants in the intervention group receive two 45 min-session of CS per week for 12 weeks in addition to their treatment as usual. Participants in the control group will maintain their treatment as usual.

Patients with chronic kidney disease (CKD) with criteria for renal replacement therapy (RRT) including uremic syndrome, have a stable state of hyperosmolarity due to urea despite not being an osmotically inactive ion. Also, these patients have alterations in urea transporters in the central nervous system (CNS) conferring a risk of neurological involvement due to an abrupt decrease in serum urea causing manifestations of the post-dialytic syndrome. Hemodialysis results in rapid removal of urea from the blood, much faster than the equilibrium rate between the brain and the bloodstream through the blood-brain barrier, resulting in an osmotic gradient that favors movement from water to the brain, causing cerebral edema, intracranial hypertension and dialysis-associated imbalance syndrome. Conventional hemodialysis (HD) uses diffusion and primarily decreases small solutes, while hemofiltration (HF) is based on convection that provides clearance mainly of medium-size molecules and small solutes with a slower rate of reduction.

Attention Deficit Hyperactivity Disorder is a disorder in which children show insufficient attention span, hyperactivity and impulsivity according to their developmental level. It is stated that in the absence of rehabilitation, the child's social and academic functionality gradually deteriorates, there are problems in cognitive function processes and executive dysfunctions that affect daily life. The aim of this study was to investigate the effects of cognitive occupational therapy interventions on executive functions in children with Attention Deficit and Hyperactivity Disorder. 21 children aged 9-12 years were included in the research (10 study group-11 control group). One individual and one group session was applied to the study group at Biruni University Occupational Therapy Unit as 2 times per week for 8 weeks. Both groups were evaluated at the beginning and after 8 weeks with Children's Color Trails Test, Verbal Fluency Test and Stroop Test T-Bag Form. Wilcoxon Paired Sample Test and Mann Whitney U Test were used for analysis of intervention results and comparison between groups.

A double-blind placebo-controlled study evaluating the effect of 1068nm NIR trans-cranial phototherapy upon the cognitive function of healthy individuals between the age of 45 years and 80 years.
