Filter by:Accumulating evidence indicates that inflammation is prominent both in the blood and central nervous system (CNS) of Alzheimer's disease (AD) patients. These data suggest that systemic inflammation plays a crucial role in the cause and effects of AD neuropathology. Capitalizing on the experience from a previous clinical trial with thalidomide, here, the investigators hypothesize that modulating both systemic and CNS inflammation via the pleiotropic immunomodulator lenalidomide is a putative therapeutic intervention for AD if administered at a proper time window during the course of the disease.
The purpose of this study is to evaluate the effects of SMR neurofeedback training on cognitive performance and electrical brain activity in elderly with cognitive impairment.
Potential study participants will be recruited at breast cancer survivor support groups. Informed consent will be obtained with a form approved by the TWU IRB and participants will complete 4 tests. Then participants will be randomly assigned to one of two computer-assisted cognitive programs. Participants will be sent by email, exercises specific to their assigned computer-assisted cognitive program from Happyneuron Pro (http://ie.scientificbraintrainingpro.eu/). Cognitive training on the computer entails 30 minutes a day, five times a week for one month. At the end of the study, the four pretests will be repeated, a satisfaction survey administered.
The investigators will answer the question of whether treating insomnia using Cognitive Behavior Therapy for Insomnia (CBT-I) can improve perceived cognitive impairment (PCI) in cancer survivors compared to a waitlist control group. The investigators will recruit 124 people with insomnia and cognitive complaints who have completed cancer treatment at least 6 months prior to the study.
Individuals with mild cognitive impairment (MCI) and subjective cognitive decline (SCD) have greater risk of developing dementia. Cognitive intervention is a topic of great interest in individuals with MCI and SCD for the purpose of preventing or delaying the occurrence of dementia. There are many different types of cognitive interventions, which aim to positively impact the cognitive functioning of an individual and have been classified as cognitive stimulation, cognitive training, and cognitive rehabilitation. However, most studies used neuropsychological cognitive measures for outcome evaluation. The impact of cognitive interventions on daily functional performance among individuals with MCI and SCD were rarely explored. In addition, cognitive training focusing on specific cognitive outcomes is suspected to have limited far transfer to everyday measures. Therefore, a multicomponent intervention which integrates several types of intervention is recommended to reach the maximum impact on daily function. The purposes of this study are to examine the effects of a multicomponent cognitive intervention on cognitive and daily functional outcomes in individuals with MCI and SCD, and to compare the effects between the two groups. In addition, the investigators will also investigate whether the demographic (e.g., age and educational level, etc.) and clinical variables (e.g., duration of cognitive complains, level of depression and baseline cognitive function, etc.) may affect the outcomes of cognitive intervention.
Increased activity in the hippocampus (i.e., hyperactivity) during a fMRI memory task was found in patients with Mild Cognitive Impairment due to Alzheimer's disease (MCI). Those with increased hippocampal activity exhibited elevated clinical progression. Reducing hippocampal hyperactivity with pharmacological treatment reduced hyperactivity and improved memory performance. The investigators of this study will test whether real-time fMRI neurofeedback will also downregulate hippocampal activity and thereby improve memory performance.
According to 2011 HAS recommendations, early detection of Alzheimer disease is the major objective in order to allow an earlier care and support. These recommendations strengthen general practitioner role, who plays a key role in the identification of cognitively impaired patients. HAS recommendations are the use of MMSE like test (Mini Mental State Examination) at general practitioner office. A self-screening test, without medical presence, would allow a self-administered cognitive assessment by the patient. A review of the literature about self-administered cognitive tests has been realized. The Self-Administered Gerocognitive Examination (SAGE) has been chosen. It is a brief, valid and reliable cognitive assessment tool, rated on 22 points, which allows an early detection of cognitive impairment, with a sensitivity close to the MMSE test. Nevertheless, SAGE has never been tested at home without medical supervision. In this study, the investigators will determine if SAGE scores at home correlates with MMSE scores at general practitioner office. Patients with inclusion criteria will be recruited during the general practitioner consultation and will have a clinical assessment included MMSE and clinical data collection. Then, SAGE will be given to the patient in order to be completed at home without medical supervision and send to the general practitioner.
Pretest and validation of the German version of the Amsterdam instrumental activities of daily living questionaire short in elderly people with normal cognition, mild cognitive impairment (MCI) or mild dementia in the German speaking part of Switzerland. The aim is to investigate the psychometric properties of the final Amsterdam instrumental activities of daily living questionaire short (A-IADL-Q-SV) German. Participants with normal cognition will be recruited in the community and participants with MCI and mild dementia in three memory clinic settings.
Alzheimer's disease (AD) has a detrimental impact on cognitive functions. Based on pilot studies results in patients with neurodegenerative brain diseases the investigators aim for promoting the brain plasticity and improving cognition by noninvasive brain stimulation (NIBS) in healthy young, healthy aged and subjects with mild cognitive impairment due to AD. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more-serious decline of dementia. Different new brain targets, cognitive tasks and stimulation protocols will be tested and optimized for specific subject groups. Design of a functional MRI (fMRI) - repetitive transcranial magnetic stimulation (rTMS) - fMRI study will enable us to explore and identify effect of age, presence of the disease and genetic risk factor (APOE4) on repetitive transcranial magnetic stimulation (rTMS)-induced changes in cognition and related brain connectivity/activations. The study results will improve our understanding of healthy and pathological brain aging and will provide novel information about the usefulness of NIBS in specific subject groups. These results will have an important impact on future non-pharmacological treatment strategies.
Background: Mild Cognitive Impairment in Parkinson's disease (PD-MCI) is considered a predictor for the development of dementia, a major source of eventual treatment-refractory disability. Physical activity, which has proved effective in improving motor symptom, has also been proposed as a possible non-pharmacological intervention for preventing/delaying the onset of cognitive impairment in Parkinson's disease (PD). Objectives: This study evaluates the effect of a 4-week rehabilitation therapy on cognitive functions in mid-stage PD-MCI patients. Methods: 40 PD-MCI patients were randomized to receive physical therapy (PT) or no physical therapy (CT) according to a controlled single-blind design. Subjects in the PT group (n. 17) attended a rehabilitation program with 6 sessions/week, each lasting 60 minutes, for 4 weeks in addition to their usual pharmacological therapy; subjects in CT group (n. 22) received only pharmacological therapy. Cognitive and motor functions were assessed at baseline (T0) and at the end of the intervention period (T1) in both groups.
