Active clinical trials for "Cognitive Dysfunction"

To investigate the impact of a long-term light treatment intervention on sleep physiology and memory in mild cognitively impaired and mild Alzheimer's disease patients living at home. The goal is also to measure the impact of the lighting intervention on caregivers' sleep, cognition, depression, and quality of life.

Frailty is the term commonly utilized to describe the geriatric syndrome that exposes the elderly to increased risk of negative health-related events. The frailty phenotypes (PF: physical or CF: cognitive) have demonstrated to predict the major negative health-related outcomes in the old population and show extensive similarities with sarcopenia (for PF) or dementia (for CF). However, the role of neurophysiological and biological factors contributing to the physical and cognitive frail condition, and in particular in which way mitochondrial dysfunction, as well as the hypertrophic and atrophic pathways assessed by genes expression, metabolomics and microbiota composition are contributing to these frail conditions, are still under debate. Therefore, the aim of this trial will be to make evidence based on the behaviors and the strategies that promote healthy lifestyle and successful human aging.

This study will compare two approaches to cognitive rehabilitation in adults with stroke 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. 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-Heath Education Lifestyle Program (BF-HELP). Both CICT and BF-HELP will involve 35 hours of training. Ten 1-hour sessions of SOPT will be scheduled in the home with training conducted independently by participants. Ten 2.5 hours of in-lab, face-to-face, therapist directed sessions will be scheduled. These sessions will feature a brief period of SOPT; the bulk of the sessions will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life; 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. Family caregivers in both groups will also receive training on how to best support participants in their therapeutic program. The study will also test if there is an advantage to placing follow-up phone calls after treatment ends. The purpose of the calls will be to support transition of any behavioral changes achieved during treatment into everyday life on a long-term basis. Participants will be randomly assigned to the interventions. 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.

This project aims to develop a new dual-task stationary cycling system that can monitor and provide feedback on the aerobic exercise intensity, while administrating appropriate cognitive trainings targeting various cognitive sub domains through a screen in front of the user. The proposed system is designed to train the brain with cognitive tasks and the body with aerobic exercises at the same time. The difficulties of the cognitive tasks are controlled by the users' previous performances on these tasks so that they wouldn't be too easy nor too difficult. Similarly, the intensity of the aerobic exercise will be monitored through an optical encoder for the cycling cadence, two power meters for the force output on the two pedals, as well as a heart rate monitor for the users' physiological response. Constant feedback is being provided to the users so that they will exercise at the correct intensity to provide the greater cardiovascular and cognitive benefits.

The purpose of this study is to determine whether a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS), combined with traditional cognitive therapy will improve cognitive function in patients with subacute stroke.

This study is designed to assess the feasibility that individualized reminiscence-based virtual music therapy sessions can enhance autobiographical memory, mood, and cognition in patients with mild cognitive impairment (MCI) or mild dementia due to Alzheimer's Disease (AD). 60 patients with MCI or mild dementia due to AD will receive two 30 minutes reminiscence-targeted virtual music therapy interventions per week for 8 weeks (a total of 16 sessions). Participants' (or supported by the study partner) self-reported and measurable outcomes including cognitive, anxiety, quality of life, and autobiographical memory will be assessed before and after the 8-week course of treatment. Blood-oxygenation level-dependent (BOLD) in functional magnetic resonance imaging (fMRI) will also be also measured before and after the 8-week course of treatment.

The study is planned as a randomized, double-blind, and sham-controlled parallel trial, in which raters and participants will be blinded to the group selection. A total of 60 participants, meeting the eligibility criteria, will be enrolled in the study and divided randomly into 3 groups (2 experimental ones with active rTMS, one of which with the addition of cognitive training RehaCom, one control group with sham-placebo rTMS).

The aim of this study is to explore the relationship between cortical hyperexcitability, abnormalities of brain network function, and cognitive dysfunction in human patients with AD and whether administration of the antiepileptic medication levetiracetam (LEV) normalizes these measures and improves cognition.

The purpose of this study is to see if stimulation of the brain can improve memory. The investigators will use a device called transcranial magnetic stimulation that can stimulate and activate a specific part of the brain that is important for memory. The study will enroll MCI subjects who will be randomly assigned to receive active or sham brain stimulation. 'Blinded' or 'sham-controlled' means that the subject will not know whether the treatment they receive is the active treatment or the non-active stimulation. In the 'sham' condition, the stimulator will turn on but will not actually be stimulating the target brain region.

Develop a game-based upper-extremity motor and cognitive rehabilitation system using custom and adaptable virtual reality simulations on a wearable device enhanced with biosensors. Participants are stage II and stage III breast cancer survivors with lasting cognitive impairments following their first round of chemotherapy. They will be randomized 1:1 into an experimental group and a sham control group. Each group will train in the home for 8 weeks, during which they will perform up to 4 rehabilitation sessions/week (based on tolerance). Each session will start with vitals being measured and logged. Each group will have three clinical evaluations: 1) at baseline; 2) at 8 weeks post-baseline; and 3) at 16 weeks from baseline for follow up. Experimental group sessions will consist of increasingly more difficult cognitive training tasks in the form of simulated tasks. Biosensors will be sampled while participants interact with these games while wearing the computer system. Sham control group will have the same number, suration and frequency of sessions, however they will play web games while wearing some the same biosensors. Caregivers of all subjects will receive a laptop to be used in filling subjective evaluation forms and sending messages to research team. Training will be in the home, so caregivers will need to support the trials by ensuring compliance with the protocol. All subjects will undergo standardized clinical evaluations at baseline, at 8 weeks and at 16 weeks from baseline. The subjects in the experimental group will have computerized measures taken during each session, and will fill subjective evaluation forms every 4 weeks of active training.
