Evaluation of the effect of preoperative intravenous administration of amantadine sulfate on the prevention of the development of early cognitive dysfunction in elderly patients undergoing laparoscopic radical prostatectomy
The process of receiving a diagnosis of mild cognitive impairment (MCI) is recognized to induce behavioral responses that can be either adaptive or maladaptive. Five specific areas of concern have been identified, including: 1) failure to plan for future decline, decreased compliance and interaction with medical care providers, 3) decreased confidence and reduced social engagement, 4) increased physical limitations and 5) decreased medication compliance. In this pilot study, participants with MCI and their study partners will participate in behavioral interventions (primarily training workshops and classes) targeting each of these five areas of potential maladaptive behaviors.
This study evaluated if the social and cultural activities decrease the incidence of dementia and frailty conditions.
Hypertension is the major risk factor for vascular cognitive impairment (VCI). One of the main limitations in the clinical approach to VCI is that, by the time that it is manifested, it might be too late to reverse the neurodegenerative process. Thus, early identification of predictive signs of later dementia is demanding for management of hypertensive patients (HT).This aim claims for new methods that compute in a cloud all possible data sources coming from patients (brain imaging, cognitive profile, clinical data), to extract discriminative aggregate biomarkers. Thus, this study aims at: 1) characterizing the predictive potential of an aggregate biomarker for dementia in HT, based on brain imaging, clinical and cognitive assessment; 2) evaluating the impact of blood pressure variability, besides systolic/diastolic blood pressure, on the progression of the aggregate biomarker; 3) assessing whether specific classes of antihypertensive drugs differently affect the progression of the aggregate biomarker. In order to do this, this study proposes to evaluate advanced brain imaging and cognitive profile in a cohort of hypertensive patients, at baseline and after a 1 year follow up, to identify an innovative signature for the development of cognitive dysfunction in hypertension. In particular, the effects of blood pressure variability and of different classes of antihypertensive drugs will be evaluated.
The purpose of this research study is to investigate the effectiveness of a memory retraining program and a processing speed program in a spinal cord injured (SCI) population. The study is designed to research how well different types of techniques can help people with SCI improve in areas where they might have difficulties such as memory or processing speed, (time it takes to process information provided).
There are no pharmacological interventions that delay or prevent the transition of mild cognitive impairment to dementia. Several studies have shown that transcranial magnetic stimulation (TMS) could be useful in increasing cognitive traits in dementia. As TMS is performed in a clinical setting, transportation, mobility and high costs of treatment, limit the number of TMS sessions dementia patients can receive. Most of the trials do not apply more than 20 TMS sessions Here, a randomized, sham controlled, paralallel group, clinical trial will be performed in order to asess the efficacy at improving cognitive traits of a novel TMS device that uses high frequency and low intensity pulses. As the device is portable and can be used from home without clinical supervision, the stimulation will be applied two times per day for a period of 6 months.
Aging tends to compromise the ability to solve problems, remember details, and process information. At the extreme level, this normal cognitive decline can interfere with independent living. Because most brain dysfunctions become irreversible before patients show clear signs in the clinic, there is a pressing need to prioritize preventative countermeasures. Exercise is a promising strategy to slow or reverse these losses. While most studies have looked at running or cycling exercise, little is known about the effects of weight lifting exercise. In addition, vascular health is intimately linked with cognitive abilities and risk of stroke, making it a primary target for intervention. Previous weight lifting studies suggest that blood vessels in the brain are a likely site of adaptation. The goal of this research is to understand how weight lifting exercise improves cognitive function in older adults. Specifically, the contribution of blood vessel changes in the brain after 12 weeks of weight lifting exercise 3 days per week. These vascular improvements may provide the link between physical and cognitive health, while simultaneously reducing the risk of cardiovascular disease and stroke. To determine this, advanced brain imaging techniques will be used to measure blood flow/volume changes in the brain non-invasively. Physical capacity (i.e. strength), body composition (i.e. lean mass, fat mass), and blood markers will also be assessed using standard protocols, and each of these variables will be tested for their relationship with cognitive functions. Understanding how weight lifting exercise improves cognitive function will support the development of comprehensive treatments targeting overall brain health. With no current cures for dementia, this information will be vital in prescribing exercise for specific patient needs to reducing the risk of dementia and stroke. In addition, the promise of exercise therapies extends beyond the target disease, having further benefits to the well-being of participants. These types of treatments positively impact fundamental aging processes, and thus reduce the risk of all-cause mortality. Even with moderate benefits to a specific disease like dementia, the global impact on healthcare would be substantial.
In patients who have had a stroke, memory problems are common. Some patients with memory problems improve over the first year after stroke, but recovery is unpredictable. The STRATEGIC study assesses patients with recent stroke and follows them up after one year. The study uses cognitive testing and advanced MRI to understand the brain's mechanism for recovery from memory problems and to identify factors that may predict later recovery.
The study aimed at assessing whether the guidelines from the European project FOCUS had an effect on adherence to a physical activity program in older women. The program consisted of two 12-week periods, in which women followed a set of pre-specified exercises (1 hour, twice per week). The first period was supervised by a monitor while the second was autonomous. Support groups, in which the contact between participants was established through information and communication technologies (social-network through the mobile phone), were set up to maintain engagement between participants. Women were randomized to three arms consisting of 2 intervention groups, with and without the FOCUS guidelines, and a sedentary control. Secondary outcomes included a battery of dimensions affecting physical performance, psychological status, and quality of life.
