Filter by:The problem of cognitive decline among the aging population has become a significant health burden, especially in light of the increase in the prevalence of dementia with age For patients with MCI (Mild cognitive impairment) there are various recommendations to deal with the disorder, including behavioral recommendations for physical exercise. Some recommendations could also be found for cognitive practice. However, currently, there is no consensus regarding effective cognitive treatment or practice for MCI. Among the populations suffering from MCI, there is a significant segment of patients with amnestic disorder. For these patients, it seems that cognitive training of memory, including verbal memory, is very important. In recent years, we have developed an effective tool for managing rehabilitation practice by monitoring the patient's engagement with an easy-to-use EEG (electroencephalogram) tool. We have shown in a variety of rehabilitation settings, that when the patient is recruited, the clinical improvement is significantly better. The aim of this study is to evaluate the ability to harness the EEG monitoring of brain engagement to achieve functional improvement in verbal memory training in patients with Amnestic MCI.
Many patients with primary brain tumors experience cognitive deficits and cognitive rehabilitation programs aim to alleviate these deficits.The cognitive rehabilitation program developed by the investigators proved effective in a large randomized controlled trial (RCT). To increase its accessibility, it was converted into the iPad-based cognitive rehabilitation program ReMind, which incorporates psychoeducation, strategy training and retraining. A pilot study and a randomized controlled trial are conducted, to evaluate the feasibility of the use of the program and the efficacy of the program in brain tumor patients after resective surgery.
The investigators aim to use the new PET radioligand, 18F-MK-6240, to detect tau pathology in cognitive healthy and mild cognitive impairment (MCI) elders. The investigators will then examine the interactions between differential tau burden and performance on cognitive tasks, functional magnetic resonance imaging (fMRI) neural activation patterns, and other cognitive and behavioral measures. By investigating these relationships, the investigators hope to understand the cognitive and behavioral outcomes of tau deposition found in specific brain regions in cognitively normal/mildly cognitively impaired adults. Furthermore, the study aims to examine how the presence of tau may contribute to the risk of subsequent cognitive decline, neurodegeneration, and dementia.
Postoperative cognitive decline (POCD) is a common and impactful outcome of surgical procedures in older adults. The pathophysiology and causative mechanisms for POCD are poorly understood. The robot-assisted radical cystectomy (RARC) is increasingly utilized. In patients undergoing RARC, Although prolonged Trendelenburg position and pneumoperitoneum can increase the cerebral blood flow, the excessive cerebral perfusion can lead to encephalemia, which reduce the oxygen uptake of brain tissue and cause insufficient oxygenation of brain tissue at the cellular level. POCD may take place due to cerebral hemodynamic changes. The goal of the current study is to investigate the combined effect of this position and CO2 pneumoperitoneum on POCD during RARC with the monitor of cerebral oxygen.
The project presented here respond to this emerging need by implementing a Reminiscence Therapy program dedicated to elderly people in an institutional context. This will be a multicenter, randomized controlled study in which the participants' allocation will be made without their knowledge. Before the randomization process, the screening evaluation will be done, which will allow to verify the presence of the inclusion and exclusion criteria. The target population will be people age 65 or above years who present cognitive decline. After the randomization process, participants will be allocated randomly in the experimental group where the reminiscence program (composed by a main strand and maintenance strand) or in the usual institutional care group. The evaluation of the participants will be carried out individually and will take place in four different moments.This study will be conducted in RSE in the central region of Portugal.
This study is affiliated to Sino Longitudinal Study on Cognitive Decline, SILCODE. To establish models of normal and pathological cognitive aging.To collect the longitudinal data of SCD population, to study the dynamic changes of brain networks so as to explore the progressive mechanisms of AD on brain networks and to construct a high-precision multi-modal model for early diagnosis.
This study is a double-blind placebo-controlled randomized clinical trial (RCT) to provide Class I evidence in support of or in refute of the efficacy of the modified Story Memory Technique (mSMT) in healthy aging (HA)and in persons with mild cognitive impairment (MCI). Outcomes will be measured through three mechanisms: (1) a traditional neuropsychological evaluation (NPE) (2) an assessment of global functioning (AGF) examining the impact of the treatment on daily activities, and (3) an optional functional magnetic resonance imaging (fMRI) scan.
Scientific evidence regarding the effects of Brain Gym®, on people with cognitive impairment is scarce. This study aimed at comparing the effects of a program based on Brain Gym® exercises against a fitness exercise program on the cognitive function, functional independence, physical fitness and quality of life in institutionalized older adults with cognitive impairment.
Low oxygen at altitude causes pauses in breathing during sleep, called central sleep apnea. Central sleep apnea causes repeated awakenings and poor sleep. Low oxygen itself and the induced oxidative stress can damage mental function which is likely worsened by poor sleep. Reduced mental function due to low oxygen can pose a serious danger to mountain climbers. However there is also mounting evidence that even in populations of people that live at high altitudes and are considered adapted, low oxygen contributes to reductions in learning and memory. Therefore there is a serious need for treatments which may improve sleep, control of breathing and mental function during low oxygen. Melatonin is a hormone produced in the brain during the night which regulates sleep patterns with strong antioxidant and anti-inflammatory properties. A study previously reported that melatonin taken 90 mins before bed at 4,300 m (14,200 ft) induced sleep earlier, reduced awakenings and improved mental performance the following day. However how melatonin caused these effects was not determined. Therefore this study aims to determine how melatonin effects control of breathing, sleep and mental performance during exposure to low oxygen.
Insulin resistance (IR), beyond its well-defined role in the appearance and progression of diabetes mellitus (DM), is the recognized pathogenetic factor underlying vascular aging. Recently, the existence of a "cerebral" IR, responsible of the appearance and progression of many forms of dementia and mild cognitive impairment (MCI), has been hypothesized. On the other hand, it is well known that DM acts as a cardiovascular (CV) risk factor per se. In the last years it has been demonstrated that also glucose normotolerant subjects who exhibit plasma glucose levels >155 mg/dL 1h-post load, have a CV risk similar to that of diabetic patients. Thus, these category of subjects is characterized by IR and, being MCI the expression of IR in the brain, the principal hypothesis of our study is that these subjects may also develop neuropsychological alterations, earlier with respect of the general population.
