Filter by:Pragmatics of language refers to the set of abilities that allow one to use and interpret language according to context and, in general, to communicate effectively. Disorders in the pragmatics of language are prevalent in various clinical populations. They are a cause of social withdrawal and worse quality of life, both for patients directly affected and for their family members. Despite this, this type of disorder is rarely considered in neuropsychological assessment and rehabilitation. This study's objective is to characterize pragmatic deficits in various neurological populations, allowing for the most accurate diagnosis possible and leading to the planning of personalized and effective Rehabilitation Plans.

The investigators investigated the effects of transcranial alternating current stimulation (tACS) on cognitive impairments in methamphetamine patients
The main objective of this project is two-fold 1. to develop a Dual-Task training exploiting the potentiality of the 360° technology in terms of interactivity and ecological validity 2. to investigate its efficacy in improving the cognitive functioning in a randomized clinical trial for 2 different populations: subjects with subjective memory complaints and mild cognitive impairment. Specifically, participants will follow an integrated training including 2 phases: 1)in-hospital rehabilitation, where subjects will be provided sessions of the training in immersive modality; 2)at-home rehabilitation, where older adults will be asked to perform at home the non-immersive version of the training using a tablet. Expected outcome is an improvement in cognitive functioning (assessed with a complete neuropsychological battery) after the training, thus advancing literature about non-pharmacological interventions in the preclinical stages of dementia along with innovative technical instruments.
Research Questions: 1. Due to the fact that most participants in past clinical trials on the Mediterranean diet were cognitively healthy individuals, and while the observed effects were significant, they were not particularly substantial, does the Mediterranean diet have similarly significant and more pronounced effects on both physical and cognitive functions in older adults with subjective cognitive decline (SCD)? 2. What is the mechanism behind the effects of the Mediterranean diet on physical or/and cognitive function? Is it through vascular protection or improvements in brain structure/brain network function? Research Objective: Conduct a cross-over randomized controlled trial to investigate the effects of a three-month Mediterranean diet on the physical and cognitive functions of older adults with subjective cognitive decline (SCD) in the community. Utilize brain MRI and circulatory biomarkers measurements to elucidate the underlying mechanisms.
Older adults suffering from a hip fracture are a significant concern, with higher incidence rates among women. Mortality rates post-hip fracture are alarming, with up to 8-fold increased risk within 3 months and significant percentages within 30 days and 12 months. Older adults with hip fracture face challenges in regaining pre-fracture level of function, especially those with cognitive impairment, which affects 25% to 40% of cases and increases mortality risk. While interventions exist, such as progressive strength training and structured exercise programs, patients with hip fracture don't consistently restore pre-fracture function, particularly in cognitively impaired patients, who are often excluded from studies. Limited evidence exists on effective management for this subgroup, with a lack of clarity on community-based rehabilitation. Although guidelines suggest exercise interventions for patients with mild to moderate cognitive impairment, the specifics remain uncertain due to insufficient research focused solely on this population. This feasibility study aims to assess the practicality and safety of implementing a 12-week individualized, progressive exercise program for older adults with hip fracture and cognitive impairment in an outpatient setting. Additionally, the investigators seek to gather qualitative insights through observations and interviews regarding participants' experiences and the perceived value of rehabilitation post-hip fracture, particularly focusing on the exercise intervention provided.
Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.
The goal of this clinical trial]is to evaluate if learning to play traditional board games could improve cognition in subjects with mild cognitive impairment and subjective cognitive decline. The main questions it aims to answer are: - Do Go and Chess improve cognition? - Is a game better than the other? Is the effect of both games on cognition synergistic? - Do Go and Chess improve quality of life? - Do Go and Chess improve mood? - Do Go and Chess improve lifestyle? Participants will be randomized to one of four groups: - Group intervention with Go, once a week, for 12 weeks - Group intervention with Chess, once a week, for 12 weeks - Group intervention with Go and Chess, twice a week, for 12 weeks - Control group
VESPA 2.0 is based on an integrative and ecological approach used for the treatment of cognitive dysfunction in patients with MCI or other neurodegenerative disorders.
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.
