This study seeks conduct a pilot study to test whether a cognitive training program can improve processing speed abilities in individuals with acute traumatic spinal cord injury.
This research aims to investigate the effect of aromatherapy on sleep duration, sleep quality, falling asleep time and cognitive functions of elderly individuals in the short term and to improve the general health status and quality of life of elderly individuals in the long term.
The goal of this double-blind, placebo-controlled randomized clinical trial is to test the effect of 12 weeks of orally administered MitoQ (mitoquinol mesylate) supplementation on cognition in 50 people with early phase schizophrenia-spectrum disorders (E-SSD) who have mitochondrial dysfunction (called high risk, or HR). Cognitive impairments in SSD can cause significant disability. Yet, there are no effective treatments for cognitive impairments in SSD. It has been shown that alterations in a certain type of brain cell (parvalbumin interneurons, or PVI) underlie cognitive deficits in SSD. These PVI, which fire at a fast rate, utilize high amounts of energy from the mitochondria and are highly vulnerable to oxidative stress. MitoQ is an antioxidant. Research has shown that, in mice, MitoQ can reduce oxidative stress in the mitochondria. The main question that this clinical trial aims to answer is: • Does MitoQ supplementation, compared to placebo, improve cognition in HR patients? Secondary questions that this clinical trial aims to answer are the following: Does MitoQ supplementation, compared to placebo: - Improve positive and negative symptoms of SSD in HR patients? - Improve functioning in HR patients? - Improve/normalize blood markers of mitochondrial dysfunction in HR patients? The investigators will enroll 100 individuals with E-SSD. These enrolled participants will participate in an initial screening visit to determine if they qualify for the actual clinical trial. At the screening visit, the investigators will ask about psychiatric history to determine diagnosis; ask about medical history; do a physical exam; collect blood and urine samples; do a pregnancy test; and ask participants to bring in their current medications in their original packaging so it is known what they are taking. After the screening visit, the investigators will invite 50 HR patients (identified with a blood test) to continue with the clinical trial. Participants who qualify for the clinical trial will be asked to: - Take a supplement (MitoQ or placebo) once per day for 12 weeks in addition to their usual medications. - Come in for a study visit every 4 weeks over the 16-week study period. At these study visits, the investigators will do a physical exam; ask about symptoms and side effects; take blood and urine samples; and ask questions about general health and well-being, quality of life, mental health, emotional health, and mood. At visits 1 (baseline) and 4 (12 weeks), participants will also take a cognitive assessment.
The goal of this randomized pilot trial is to test a chronic pain self-management program customized for people living with both chronic pain and cognitive impairment. The main questions it aims to answer are whether this program is feasible and acceptable, and whether it shows potential for improving pain-related outcomes. Intervention group participants will receive education and support from a community health worker in 7 weekly telephone sessions, and will watch a series of educational videos discussing a variety of chronic pain self-management skills. A control group will not receive the program, but after the final data collection point will be invited to attend a one-time remote session that summarizes intervention content, and will receive all program materials. Researchers will compare intervention and control groups after the program ends to see if the intervention group has less pain interference with daily activities.
This is a single-center, randomized controlled clinical trial with a parallel-group design conducted at Minia University hospital.
The goal of this intervention study is to test the effects of a nurse-led mobility intervention (known as the OASIS Walking Intervention (Older Adults performing Sit to Stands and Walking Intervention)) in older adults with cognitive impairment, such as dementia, in transitional care programs. The main questions this study aims to answer are: - Is the study doable and are older adults satisfied with the intervention? - Does the intervention improve older adults' muscle strength, mobility, functional status and quality of life? Participants will be asked to do the following: 1. Be interviewed once so that a patient-centred communication care plan can be made 2. Do sit to stand activity 3. Walk as part of a walking program.
This study will evaluate a new form of non-invasive deep brain therapy for individuals with Alzheimer's disease. Low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The trial will evaluate brain target engagement using magnetic resonance imaging, PET imaging, and numerical scales of cognitive performance.
This study will compare two approaches to cognitive rehabilitation in adults with long COVID with persistent, mild to moderate, cognitive impairment. Both approaches will feature a web-based computer "game" that trains cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. This training is termed Speed of Processing Training (SOPT). One approach will add (A) in-lab training on everyday activities with important cognitive components and (B) procedures designed to transfer improvements in cognition from the treatment setting to everyday life. Component A will include work-related tasks. This approach is termed Constraint-Induced Cognitive Therapy (CICT). The other approach will add (A) in-lab training on relaxation, healthy nutrition, and healthy sleep and (B) procedures designed to promote integration of these lifestyle changes into everyday life. This approach is termed Brain Fitness Training (BFT). A subset of participants, who qualify for and and desire vocational rehabilitation (VR), will receive VR from the Alabama Department of Rehabilitation Services (ADRS) in addition to CICT or BFT. ADRS VR will include career counseling, prescription of on-the-job accommodations, and guidance on return-to-work. Those in the CICT + VR group will also receive on-the-job coaching from a peer mentor for a month after completing training. CICT, with or without VR, will involve 30 hours of training. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of SOPT; the remainder will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life and improving skills essential to work; the set of the latter procedures is termed the Transfer Package. To accommodate the demands of participants' other activities, training sessions will be permitted to be scheduled as tightly as every weekday over 2 weeks or as loosely as every other weekday or so over 4 weeks. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. BFT, with or without VR, will involve 30 hours of training following the same schedule as for CICT. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of SOPT; the remainder will be committed to in-lab training on the target behaviors (healthy sleep, nutrition and relaxation habits) and the procedures designed to promote transfer of behavior change to daily life. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. Participants will be randomly assigned to the interventions. Randomization will be stratified by whether participants qualify for and desire VR from ADRS or not. If yes, participants will be randomized in equal numbers to CICT + VR or BFT + VR. If no, participants will be randomized in equal numbers to CICT or BFT. Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6- and 12-months afterwards. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life. Another important outcome measure will be whether or not participants were able to return back to work or had significant improvements in their work activities.
This study will test the feasibility and effectiveness of an innovative model of care for cognitively impaired patients with heart failure. This program aims to improve cognition, reduce dementia risk and cardiovascular events, and will be supported by innovative digital technology for wide scale rollout and implementation. Findings from this research will transform the way healthcare is delivered to cognitively impaired patients with heart disease who have a very high risk of developing dementia.
