Filter by:This is a pilot study to examine the feasibility of a formal 30-minute daily program on a tablet computer (simply a "tablet") in subjects with mild cognitive impairment (MCI). The purpose of the program, known as Kodro Solution, is to increase physical activity, maintain social interaction, improve nutrition and exercise cognitive skills using a tablet. In addition to feasibility, outcome measures will include: (a) health-related quality of life, (b) self-esteem, (c) activities of daily living, (d) socialization, (e) mood, and (f) cognition. Study participants must have a study partner who can assist them with training on use of the tablet and the Kodro Solution program. Fifty (50) study subjects and their study partners will be recruited at the Wien Center. A delayed start design will be utilized. Study subjects will be randomly assigned to either active treatment (Kodro+) or delayed treatment (Kodro+D). Active treatment with Kodro Solution will be initiated at the baseline visit for Kodro+ subjects and 12 weeks after baseline for Kodro+D subjects. The 12-week period without tablets will serve as a control. Active treatment with Kodro Solution will continue for 36 weeks for the Kodro+ subjects and 24 weeks for the Kodro+D subjects. For both groups, the outcome measures will be assessed at baseline, week 12 and week 36. The lagged design will facilitate enrollment and enable the assessment of a dose effect.
Dementia is a very frequent cognitive disorder among elderly individuals. Its prevalence is about 15-20% of the population over the age of 65. The most common forms of dementia among the elderly demented patients are Alzheimer's disease (AD) (prevalence of 70%) and Vascular dementia (VD) (prevalence of about 30-40%).There is also a high rate (about 40%) of coexisting of AD and VD among the dementia patients, defined as mixed dementia. Mild Cognitive Impairment (MCI) is a pre-dementia phase of cognitive decline. It is also considered as a prodromal phase of both VD and AD. Its basic clinical features include: cognitive concern, reflecting a change in cognition, reported by the patient or informant (i.e., historical or observed evidence of decline over time), with objective evidence of impairment in one or more cognitive domains (i.e., by formal cognitive testing), as well as preservation of independence in functional abilities and not being demented (i.e., no significant impairment social or occupational functioning). Hyperbaric oxygen therapy (HBOT) has been investigated for treatment of numerous diseases for more than 300 years. The principal effect of HBOT is increasing the solubility of oxygen in plasma to a level sufficient to support tissues with minimal oxygen supply carried on by hemoglobin. Clinical studies published this year present convincing evidence that hyperbaric oxygen therapy (HBOT) can be the coveted neurotherapeutic method for brain repair. Thus, it seems that HBOT might be an efficient and clinically feasible method capable of increasing tissue/cellular oxygenation and effectively evoking neuroplasticity in the chronically vascular-lesioned areas during the post microvascular lesion phase. This is a prospective, randomized, control crossed over, study evaluating the effect of HBOT in patients suffering from Mild Cognitive Impairment and Vascular Subcortical Ischemia.
The aim of this study is to perform a whole-genome linkage analysis for identification of the susceptibility loci for POCD
Mild cognitive impairment (MCI) is a significant risk factor for dementia. Persons with MCI experience cognitive changes, most typically affecting memory; that are greater than those experienced in "normal" aging. However, these cognitive changes in MCI, unlike in dementia, are not significant enough to markedly interfere with functional independence. In addition to cognitive change, some people with MCI also experience elevated symptoms of depression and anxiety, which adds to their risk of developing dementia. Close family are also impacted by their relative's MCI and show mild physical (e.g., increased incidence of systemic health problems such as high blood pressure) and mental health declines (e.g., elevated symptoms associated with depression and anxiety) that are similar, though not as severe, to those experienced by caregivers of a relative with dementia. Programs aimed at behavioural intervention have real potential to reduce and/or prevent negative health outcomes associated with MCI and future dementia by promoting positive behaviour changes. We wish to scientifically establish the utility of a behavioural intervention aimed at addressing the needs of both the person with MCI and their close family member, with the ultimate goal of lowering current and future susceptibility to mental health declines and chronic disease in people living with MCI. We have an 8 session (16 hour) program, where participants with MCI and their close relative are together for the first half of each session, which is devoted primarily to enabling positive lifestyle choice. In the second hour the group splits up, with MCI clients engaging in memory training while their close family member participates in a psychosocial intervention.
Interventional Study of Early Postoperative Cognitive Dysfunction in Elderly Patients Undergoing General Anesthesia The main purpose of this study is to determine the incidence of early postoperative cognitive dysfunction in elderly patients and its time course. This study will first evaluate the preoperative cognitive function of elderly patients based on several criteria including complete patient history, laboratory and instrumental exams, and the following measures in order to identify conditions and pathologies that may influence cognitive function. - Mini Mental State Examination - Geriatric Index of Comorbidity - Geriatric Depression Scale The following neuropsychological tests will be performed on the same day within 7 days of surgery (baseline): - Trail Making Test B-A - Digit Span - Digit Symbol Substitution Test The three cognitive function assessments will be repeated at the following postoperative time points and the change from the preoperative baseline to each time will be evaluated: - Day 2 (time point 1) - Day 4 (time point 2) - Between days 85 and 90 (time point 3) If the patient seems confused before the postoperative administration of these tests, the Neecham Confusion Scale will be used to evaluate the patient for the presence of postoperative delirium; if delirium is not detected, the cognitive function tests will be administered.
Visual cognitive deficits in children are frequent, with an impact on working and daily activities. Optometric therapy may improve those functions, however few studies have been performed. We aim to evaluate the efficacy of such therapy by a comparative study between two groups of children aged between 5 and 12 after 6 months of rehabilitation.
Background: Mild Cognitive Impairment (MCI) is a condition characterized by memory problems more severe than normal cognitive changes due to old age, and less severe than dementia. Reduced working memory (WM) is regarded as one of the core symptoms of an MCI-condition. Recent studies have indicated that WM can be improved trough computer based training. Objectives: The objective of the study is to evaluate if working memory training is effective in improving working memory in elderly MCI-patients. Further, to evaluate if cognitive training relates to structural changes in the white and gray matter of the brain, assessed by structural Magnetic Resonance Imaging. Cognitive phenotypes related to memory impairment and progression to dementia will also be investigated. Patients and Methods: The proposed study is a blinded, randomized and controlled trail that will include 90 elderly patients from a Memory Clinic diagnosed with MCI. The groups will be randomized to either training or a placebo version. The intervention is computerized working memory training performed for 45 minutes over 25 sessions. Neuropsychological assessment and structural MRI will be performed before, 6 and 12 months after training. Relevance: Currently there is no known treatment available for mild memory impairment/MCI, and few studies on specific cognitive training in MCI-patients have been performed. The proposed study has received funding from a Norwegian Health Region. If computer based training results in positive changes to memory functions in MCI patients this may represent a new, cost-effective treatment. Secondly, evaluation of training induced structural changes to grey or white matter may improve our understanding of the mechanisms behind effective cognitive interventions in MCI patients.
Hip fractures incidence grows rapidly with the aging of the population. After indicated surgical treatment, hip fracture patients experience high rates of postoperative complications, postoperative delirium (PD), postoperative cognitive dysfunction (POCD), leading to poor postoperative recovery during hospitalization, which can cause disability, distress for both patients and their families, are associated with other medical complications and account for significant additional health care costs. We currently use dexmedetomidine in elderly patients with hip fractures undergoing hip hemi-arthroplasty in order to improve postoperative recovery and prevent and treating PD and POCD. Dexmedetomidine is a drug used for sedation in critically ill patients that provides some pain relief and controls the bodies response to stress. The sedation produced by dexmedetomidine appears more similar to natural sleep than any other drug used for anesthesia and postoperative sedation. Data suggesting that dexmedetomidine can prevent delirium following cardiac surgery and the developing understanding of the causes of PD and POCD suggest that dexmedetomidine will be particularly effective.
background: The Chronic Fatigue Syndrome (CFS) presents many disturbances multidimensional affect holistically to people who have the disease and current management of fatigue, pain, anxiety, depression and sleep disturbances present in this clinical entity is unsatisfactory. Hypothesis: The hypothesis of this essay is to contrast that acupuncture is more useful than placebo. The investigators suggest the use of a clinical study protocol (PEC), randomized, placebo-controlled, acupuncture technique, aimed at increasing the patient's sense of well-being, relief of pain and stiffness, acupuncture is effective to reduce fatigue, anxiety, depression and sleep disorders in patients diagnosed with CFS.
Patients of vascular cognitive impairment-no dementia (VCIND) in one group is prescribed cilostazol,in the other group is prescribed aspirin. Evaluate both of them in cognitive function, MRI and other sides at given time. The investigators hypothesize that cilostazol is more efficient and safer than aspirin in patients with VCIND.
