The majority of school-age children with sickle cell disease (SCD) experience neurocognitive deficits, even in the absence of stroke. In particular, deficits in attention and working memory have emerged as two of the most common neurocognitive sequelae of SCD. Thus, the goal of the present proposal is to address feasibility and compliance of a novel computerized cognitive training program, Cogmed. Pilot data will also be collected to establish preliminary efficacy. Twenty-four children meeting initial age and diagnostic criteria will be identified and approached about participation by their attending physician during regularly-scheduled SCD clinic visits. Baseline assessments will include a brief measure of intellectual functioning, a brief cognitive testing battery evaluating processing speed and working memory, in addition to questionnaires regarding behavior and quality of life. Children will then be randomized to the computerized CT program Cogmed (n=12) or a waitlist control (n=12). Participants enrolled in the computerized CT program will be asked to complete 25-sessions of Cogmed over a five to eight week period (3 to 5 sessions per week). Following completion of the program, children and their parents will be asked to return to clinic for a follow-up visit. After a five to eight-week waiting period, children in the waitlist condition will also be asked to return to clinic for a second visit. Following this assessment, participants initially enrolled in the waitlist will be offered an opportunity to participant in the intervention. If interested, they will follow the same intervention protocol described above. These children will return to clinic for a third visit following completion of the intervention. Compliance rate and its confidence interval will be calculated for the overall study population. A t-test for binomial proportion with continuity correction will be used to examine whether the compliance rate is lower than the target. Participants' change in criterion outcomes will be evaluated (i.e., those neurocognitive measures such as attention, executive functioning and working memory, that are most closely related to the trained tasks).
There are guidelines on the management of AD in China, the evidence adopted in the guidelines are mostly from the trials conducted in other countries due to very limited Chinese data available for local systematic review. Therefore, more local evidence on dementia care is needed for the development of an evidence-based guideline appropriate for people living in China. Meanwhile, the inadequate implementation of the current AD guideline, which results in the low diagnostic rate and high diagnostic leakage, may bring about extra barriers for AD patients to access dementia care service in different areas nationwide. However, there is no data on the clinical pathway about how physicians follow the dementia guideline in the routine practice. Therefore, research is needed to learn clinical diagnostic process and treatment patterns of physicians to people with AD in routine practice and help address the low accurate rate of AD clinical diagnosis and low anti-dementia drug prescription in the real world and support guideline development.
In 1906, Dr. Alois Alzheimer first described the disease that later took his name. Today, 100 years later, 24 million people worldwide suffer from Alzheimer's disease or other dementias. The term 'dementia' is clinical and is used to describe brain disorders that cause decline in mental functions, memory first and then speech, judging and overall behavior. Alzheimer's disease is by far the most common form of dementia, followed by vascular dementia, dementia with Lewy, the frontotemporal dementias etc. In Greece there are 141,000 patients with dementia. With increasing life expectancy, the figures are expected to increase dramatically in the future. Alzheimer's disease is the most common form of dementia, as well as 50-60% of patients with dementia suffer from this disease. The second most common type of dementia is vascular, ie that associated with cerebrovascular disease and is the 15-30% of all dementia cases and is most common between the ages of 60-70 years and is more common in men than women. It is estimated that 5% to 8% of people over 65 suffer from dementia, while in industrialized countries ranges at the following levels :15-25% over 85 and 32% over 90 years. Dementia is characterized by a slow onset and progressive course. The syndrome includes disorders in general intelligence, learning and memory, problem solving, perception, judgment, executive function, language and synergy of movement, but without impairment of consciousness. Alzheimer's disease is a neurodegenerative disorder with distinct clinical and histopathological features, although with variations from person to person. In its early stages it is sometimes difficult to diagnose cognitive impairment from normal aging of the brain. With the passage of time, the continuous decline in recent memory, fluency, ability for spatial orientation ultimately restricts the autonomy regarding basic activities of daily life such as managing finances. The anxiety and depression complicate diagnosis in early stages, but gradually decline with loss of sensitivity. Intermediate stages of the disease require increasingly supervision in daily self-care activities, such as personal hygiene and clothing. In the advanced stages are usually essential nursing care in institutional context. The severity of symptoms of the disease varies and is determined by premorbid factors such as education, gender, cultural background. Epidemiological studies have shown as protective factors against the onset of dementia, higher education, taking estrogen and anti-inflammatory drugs. On the other hand, age, family history of dementia, head injury, hypertension and Down syndrome are risk factors for developing the disease. Finally, some genetic factors appear to be protective, and other pressures to the disease.
The purpose of this study is to determine if non-invasive electrical brain stimulation can improve word-retrieval in Mild Cognitive Impairment (MCI).
High levels of psychological stress have been reported by 90% of patients with MS experiencing disease exacerbation, and approximately 39% of those with more stable disease course. These stress levels are comparable to patients with a clinical diagnosis of major depression. Cognitive dysfunction affects approximately 40% of community surveyed MS patients, and stress may exacerbate the cognitive burden. Studies have shown that Cognitive Behavior Therapy (CBT) is effective in treating psychological stress. Studies have also shown that exercise is beneficial to mood and cognitive function. Therefore the proposed study will test the comparative benefits of combining CBT and Exercise as an intervention for stress and cognitive dysfunction in MS subjects. The 2 active treatment conditions will be compared with a waitlist control condition. There are 4 broad aims to this study: 1) to compare the relative efficacy of CBT, Exercise, and CBT-Exercise for stress in MS, 2) to examine the extent to which neuropsychological features of stress and MS, especially working memory and executive functioning, improve following treatments, 3) to determine the extent to which neuropsychological factors are associated with successful treatment response and improved quality of life, and 4) to determine if combined CBT-Exercise confers greater benefits on measures of stress and neuropsychological functioning compared with Exercise alone. The study hypotheses are: 1) All active treatment conditions will lead to significantly greater improvement on measures of stress at post-treatment and follow-up compared to waitlist controls, 2) Combined CBT-Exercise will lead to comparatively greater symptom reduction compared to all other conditions at post-treatment and follow-up assessments on measures of stress, 3) All active treatment conditions will lead to significant improvement in neuropsychological functioning (particularly measures of working memory and executive functioning) at post-treatment compared to controls, and 4) Combined CBT-Exercise will lead to greater improvement in neuropsychological functioning compared to all other conditions at post-treatment. The study design allows for examination of the potential additive benefits of CBT and Exercise to usual therapy for patients, and its feasibility as a viable treatment model for MS outpatient clinics and community-based intervention programs. This study will shed light on the treatment of sub-threshold symptoms that are strikingly common in MS population, but often overlooked in favour of more concrete diagnoses (e.g. major depression disorder). This proposed study will also be the first to determine whether evidence-based non-medical treatments for stress and mood disturbances in MS reduce underlying cognitive substrates associated with the illness and known to be exacerbated by stress.
the purpose of this study is to investigate whether propofol and sevoflurane have difference effect on cerebral oxygenation .
In a retrospective analysis of data from 1100 patients, disease-delaying effects of Cerefolin®/CerefolinNAC® were examined in terms of cognition. The purpose of the current study is to expand the retrospective study dataset by prospectively collecting additional biomarker and imaging data.
The proposed randomized controlled trial will evaluate the effects of treadmill training augmented with virtual reality on fall risk. 300 older adults with a history of falls will be recruited to participate in this study. This will include older adults (n=100), patients with mild cognitive impairment (MCI) (n=100), and patients with Parkinson's disease (PD)(n=100). Subjects will be randomly assigned to the intervention group (treadmill training with virtual reality) or to the active-control group (treadmill training without virtual reality). Each person will participate in a training program set in an outpatient setting 3 times per week for 6 weeks. Assessments will take place before, after, and 1 month and 6 months after the completion of the training.
The proposes of this study are 1. To understand the physical activities of patients with cognitive impairment in Taiwan and construct the validity and reliability of the physical activity questionnaire and actigram in this population. 2. To understand the relation between brain structure (brain tractography and resting state functional MRI) and cognitive and physical functions of patients with cognitive impairment, the capability of activity and social engagement (including quality of life). 3. To understand the efficacy of exercise on the brain structure (brain tractography and resting state functional MRI), cognitive and physical functions, the capability of activity and social engagement (including quality of life) of the patients with cognitive impairment. The study aims to establish the data base of physical activity of patients with cognitive impairment in Taiwan. We will also analyze the efficacy of exercise with ICF model on physical function, physical activity and social engagements to provide an optimized design of exercise program for patients with cognitive impairment in the future.
