Filter by:Normal ageing presents subtle cognitive changes that can be detected before meeting the criteria for Mild cognitive impairment (MCI). Older people with low cognitive reserve and who receive limited cognitive stimulation are at greater risk of deterioration. In this regard, cognitive stimulation (CS) has been identified as an intervention that reduces this risk, provided that its design considers the differences in the level of cognitive reserve (CR) acquired throughout life and the baseline level of cognitive functioning. The general objective of this study is to evaluate, through a randomized clinical trial, the effectiveness of a computerized cognitive stimulation program, designed and adapted from Occupational Therapy based on the level of cognitive reserve in older adults in Primary Care. 100 participants will be randomized in a stratified manner according to the level of cognitive reserve (high/low), assigning 50 participants to the control group and 50 participants to the intervention group. The intervention group will carry out a computerized cognitive stimulation intervention designed and adapted from occupational therapy according to the level of cognitive reserve, through the "stimulus" platform. The main result expected to be achieved is the improvement of higher brain functions. As secondary results, the investigators expect that those cognitive aspects most vulnerable to ageing will decrease more slowly (in areas such as memory, executive function, attention and processing speed) and that the cognitive reserve of the participants will increase, in addition to being able to balance gender differences in these aspects. The investigators think that these results can positively impact the creation of adapted, meaningful and stimulating CS programs in older adults to prevent MCI and experience healthier ageing.
The current project aims at assessing the impact of various cognitive telerehabilitation approaches on patients with Mild Cognitive Impairment (MCI) associated with neurodegenerative diseases, namely Alzheimer's disease (AD) and Parkinson's disease (PD). The study focuses on non-pharmacological interventions to maintain patients' residual functionality, limit disease progression, and improve quality of life for both patients and their caregivers. This longitudinal and multicenter study applies innovative cognitive telerehabilitation (TR) methods and evaluates their impact on functional parameters obtained with high-density electroencephalogram (HD-EEG) and resting-state functional magnetic resonance imaging (rsFMRI). The goal is to identify neurophysiological correlates of the effects of three different cognitive TR in individuals with MCI due to neurodegenerative conditions. The study aims to: - Identify correlations between improvement in cognitive performance and functional brain data. - Use acquired knowledge to develop neurologically guided TR approaches for broader use. The research will include patients diagnosed with MCI associated with neurodegenerative diseases. Primary outcome measures include changes in resting-state brain connectivity assessed through HD-EEG and rsFMRI. Secondary outcomes involve the assessment of changes in neuropsychological measures, caregiver burden, immediately after rehabilitation and after longitudinal follow-up. The study is designed to last 30 months, with follow-up assessments at three time points. The primary outcomes will be evaluated using rsFMRI and HD-EEG instrumental acquisitions, the secondary outcomes will be evaluated using clinical assessments and neuropsychological tests.
This study aims to validate the Lithuanian version of the Brief Negative Symptoms Scale, Calgary Depression Scale for Schizophrenia, and Schizophrenia Cognition Rating Scale in a Lithuanian sample. This will be done by comparing results obtained from the Brief Negative Symptoms Scale, Calgary Depression Scale for Schizophrenia, and Schizophrenia Cognition Rating Scale with results obtained from the Positive and Negative Symptoms Scale, the Montgomery Asberg Depression Rating Scale, and the Montreal Cognitive Assessment test.
The goal of this clinical trial is to evaluate the role of memantine in preservation of memory and neurocognition in patients undergoing craniospinal irradiation. Participants will be randomised into two arms and the interventional arm will receive memantine along with the standard treatment. Researchers will compare the neurocognitive tests of participants in both the arms to see if memantine leads to significant preservation of memory and cognition post radiation therapy.
This is an observational cohort study of long-living adults (participants aged 90 and above) from the Central Federal District of Russia. The study seeks to determine the genetic and cellular and molecular determinants of healthy longevity and to assess the impact of lifestyle and socioeconomic and environmental factors on healthy longevity. The study is expected to result in the development of a panel of markers of healthy longevity and/or a model of healthy aging based on the analysis of all factors under consideration.
Cognitive therapy software for improving cognitive function for patients with mild cognitive impairment
Hereditary spastic paraplegia type 4 is the most frequent mutation of hereditary spastic paraplegias. It is commonly described as pure, with progressive weakness of the lower limbs, pyramidal syndrome and vesico-sphincter disorders. However, cognitive disorders have been reported for over 20 years, but remain poorly characterized.
The goal of this pilot study is to assess the feasibility of adapting and delivering the existing home-based epilepsy self-management intervention, HOBSCOTCH, for people with Parkinson's Disease (PD) The main questions it aims to answer are: 1. Can the current HOBSCOTCH program be adapted for people with PD? 2. Will people with PD experience improved quality of life similar to that found in people with epilepsy after participating in the HOBSCOTCH program? Participants will be asked to: - attend nine, one-hour virtual (online and/or by telephone) HOBSCOTCH-PD sessions with a one-on-one certified HOBSCOTCH-PD coach - complete a brief clinical questionnaire about their diagnosis of PD - complete two questionnaires before and after the HOBSCOTCH-PD sessions about their quality of life and about memory and thinking processes - keep a short daily diary about their PD symptoms and use of the self-management strategies taught in the HOBSCOTCH-PD program - complete a brief Satisfaction Survey after the entire HOBSCOTCH-PD program
The ENIGMA study is a single-centre prospective clinical observational study with the aim to investigate vascular contributions to cognitive decline and dementia. By studying MRI-defined capillary dysfunction and EV profiles, the ENIGMA study links novel imaging and basic research techniques to a clinical cohort of stroke patients. With this study we hope to enhance the understanding of the mechanisms behind post-stroke cognitive decline and dementia.
The objective of this trial is to evaluate the effect of the consumption of a mixture of extracts and DHA on the mild cognitive impairment.
