Filter by:A variety of non-pharmacological interventions have been used in the management of Alzheimer's disease (AD) and similar cognitive disorders in elderly, yet no therapeutic modality has demonstrated conclusive positive results in terms of effectiveness. Although it is still unknown what triggers AD, recent studies have shown that AD is associated with brain energy depletion, oxidative stress, and mitochondrial dysfunction. Since supplemental molecular hydrogen (H2) supports cell energy production and acts as a highly bioavailable mitochondria-related antioxidant, it may provide an ideal agent to facilitate treatment and perhaps prevention of AD and similar cognitive disorders in elderly. The overall hypothesis to be evaluated in this project is that administration of H2 will positively affect patient-reported outcomes and clinical biomarkers in men and women suffering from AD.
This study investigates the neural mechanisms of motor and cognitive networks using cognitive assessment, reaction time measurement, high-density EEG and fMRI.
Cognitive rehabilitation is defined as a systematic functionally oriented intervention of therapeutic cognitive activities based on the assessment and understanding of patient's brain behavior deficits. This project focuses on restoring cognitive functions in order to understand the underlying deficits in the patient's brain by developing integrated cognitive rehabilitation scenarios in virtual reality that combine memory, attention and problem solving training with context specific motor movements.
This was a Phase 2, multicenter study to assess the extent and patterns of [18F]flutemetamol uptake in the brains of 3 groups of Japanese subjects: HV, aMCI, and pAD, and to assess the reproducibility of brain uptake and of image interpretation. Subjects underwent open-label intravenous (i.v.) administration of Flutemetamol F 18 Injection and PET imaging of the brain. Blinded visual image reads were performed by 10 independent board-certified readers (5 Japanese and 5 non-Japanese) with nuclear medicine image interpretation experience. The blinded visual assessments were compared with the subject's clinical diagnoses, and the agreement between the image interpretations made by the 2 groups of readers (Japanese and non-Japanese) was determined.
REINVENT is a non-interventional, multi-center, research network-based cross-over study evaluating the potential utility of a telehealth platform in improving the efficiency of clinical trials. The study aims to enroll 30 subjects from primary care practices coordinated through a single main study site. Potential subjects will be screened and randomized (1:1) at Visit 1 into a 2-period crossover design study where 4 standard cognitive outcome measures are administered at Visits 2 (Day 30 ±7) and 3 (Day 90 ±7), either remotely or during an in-person visit.
The main objective of the present study was to evaluate whether cerebral oxygen saturation is associated with an increase of NPOBC in pediatric patients undergoing major surgery.
Volatile anesthetics interfere with cerebral blood flow and reperfusion-ischemia injury via the mechanism known as a preconditioning. A transient deterioration of local hemodynamics and oxygenation during carotid endarterectomy (CEE) might involve both hemispheres of brain and affect postoperative cognitive function. The goal of this study was to assess the effects of anesthetics on perioperative cerebral oxygenation and cognitive functions.
The study assesses cognitive complaints in newly diagnosed patients with obstructive sleep apnea with no medical-comorbity affecting cognition. Cognitive complaints will be compared to healthy controls matched on age, sex and educational level. Factors related to cognitive complaints will also be assessed, including anxiety and depressive symptoms, complaints of fatigue and sleepiness, quality of life, psychological coping strategies and objective measures of cognition. Patients starting treatment for sleep apnea (continuous positive airway pressure or mandibular repositioning device) will be reassessed on all measures after 6 months of treatment to study the impact of treatment as usual on cognitive complaints and its related factors.
This study is geared toward characterizing the recovery of brain activity and cognitive function following treatments of electroconvulsive therapy and ketamine general anesthesia.
This study is aimed to investigate the efficacy of an 12-week Chinese calligraphy training program for enhancing cognitive and emotional functions of older adults with mild cognitive impairment. Participants are tested with several cognitive tests and electroencephalography (EEG), psycho-physical parameters and brain activities are recorded. Results are compared at pre-intervention, post-intervention, and 6-month post-intervention to provide evidence of benefits of Chinese calligraphy practice.
