Filter by:Multiple studies in the spinal cord injury (SCI) population have documented deficits in learning and memory (LM) and processing speed (PS) that adversely impact daily life and the ability to benefit from rehabilitation. The investigators have previously attributed the cognitive deficits demonstrated in the SCI population to low blood pressure (BP) and cerebral blood flow (CBF) and are currently conducting a study to determine the effect of a 30-day elevation in BP (using midodrine hydrochloride - an alpha agonist) on CBF and cognitive performance compared to placebo in hypotensive individuals with SCI. In addition, the investigators believe that cognitive behavior therapy (CBT) may improve cognition independent of changes in BP and CBF in individuals with SCI. The current randomized clinical trial (RCT) will examine the efficacy of 2 treatment protocols shown to be effective in improving cognitive performance in other neurologically impaired populations for use in persons with SCI demonstrating (1) LM impairment and/or (2) PS impairment on objective measures of cognitive functioning during a complete Neuropsychological assessment. Two methods of outcome assessment will be used to examine treatment impact: (1) a traditional Neuropsychological assessment (NP) and (2) an assessment of global functioning (AGF) composed of broader outcome measures that examine the impact of the treatment on everyday life activities. In this way, the investigators will be able to objectively evaluate the presence or absence of changes in memory performance through a NP assessment, while also evaluating the impact of this treatment protocol on everyday life through the AGF. While most studies evaluating the efficacy of cognitive retraining usually employ a pre- and post-training evaluation, such evaluations have been criticized for their lack of ecological validity (i.e., real world generalizability). The present design allows the assessment of the efficacy of these treatment techniques within an SCI population using traditional measures, as well as the assessment of the impact that treatment has on everyday life. The investigators will additionally evaluate the long-term efficacy by including a 6-month post-treatment follow-up. Few studies examine long-term effects, but given the time, labor and expense involved, it is critical to demonstrate long-term efficacy.
As individuals grow older, a number of factors can reduce our cognitive (or thinking) abilities such as "normal" aging, neurodegenerative diseases, and cardiovascular disease. This study will evaluate whether cognitive rehabilitation and transcranial electrical stimulation (TES) can improve cognitive abilities. Cognitive rehabilitation refers to methods that are used to improve tasks people have trouble doing in everyday life. Transcranial electrical stimulation uses small amounts of electricity to try to alter brain functioning. These approaches may help improve cognitive abilities like attention, learning, memory, finding words, and problem solving as well as everyday functioning. The goal of this study is to identify how to best use these methods, either alone or in combination.
The purpose of this study is to test the effects of tDCS (Transcranial Direct Current Stimulation) on stroke patients with working memory problems.
The primary objective of this multicenter observational study is to determine the effect size of the relationship between DCI and neuropsychological impairment 14-28 days and 3 months after aSAH. Secondary objectives are the feasibility to administer and the validity of the MoCA in an intensive care unit setting, as well as the test/retest reliability of the MoCA in patients with acute brain damage in absence of aSAH.
The purpose of the study is to evaluate the effect of food, gender, and age on the single-dose pharmacokinetics (PK) of SUVN-D4010.
Follow-up after treatment with Extracorporeal Membrane Oxygenation (ECMO) at the ECMO Center Karolinska. Patients: adult survivors treated with ECMO for severe refractory respiratory failure at least 5 years earlier. Investigations: brain and pulmonary radiographic morphology, cognitive testing, pulmonary function testing, exercise tolerance, quality of life and mood disorder screening.
Despite the high prevalence of Alzheimer's disease (AD), its underlying mechanisms remain poorly understood. An emerging body of evidence supports disorientation as an early marker for AD-related neurodegeneration. In this study we intend to collect, coregister and analyze Positron Emission Tomography (PET) and , functional and structural magnetic resonance imaging (MRI, fMRI) data from AD-spectrum patients to establish orientation as core disturbance in AD.
This study evaluates the influence of premedication on cognitive functions in patients undergoing transurethral resection of bladder tumor under spinal anesthesia. The aims of premedication are anxiolysis, analgesia and the reduction of perioperative risk among the patients with comorbidities. The patients will be randomly allocated to receive premedication either with opioid solely or with benzodiazepine combined with opioid. The anesthetic technique is standardized.
This is a pilot randomized control trial with single blinding of the assessor that will be conducted in two nursing homes residence to evaluate the applicability of a physical exercise program performed in an aquatic environment compared with the same realization but land-based to reduce falls in the institutionalized old people. The secondary objectives are to study the applicability of the intervention in improving balance, function, gait mobility, muscle strength of the lower limbs and the perception of the intervention.
The primary purpose of this study is to test the effects of a targeted, computerized cognitive training program on verbal memory in older women who have undergone chemotherapy treatment for early-stage breast cancer. As measured by neuropsychological assessment, this treatment will result in improved verbal memory. Secondarily, processing speed and naming abilities are expected to improve. Enhanced self-perception of cognitive ability is also expected.
