Filter by:In this study, patients with aged-related hearing loss with depression and without depression were evaluated by audiometry (pure tone audiometry and speech audiometry), cognitive function assessment (MMSE scale for simple mental state test, MoCA Scale for Montreal Cognitive Assessment), and depressive symptoms assessment (GDS-15 and HAMD), resting state EEG. The ananlysis of resting state EEG included power spectral density, traceability analysis, functional connectivity, microstate, clustering coefficient, characteristic path length, characteristic path permeability, and compatibility coefficient. EEG signals were used to explore the activation of brain regions and poor connectivity of brain regions affected by cognitive reserve dissonance on the level of brain imaging. This paper innovatively explores the influence of cognitive reserve dissonance on depressive mood in senile deafness by means of audiological assessment, cognitive function assessment, depression symptom assessment, resting state electroencephalography (EEG) and other technical means. Auditory and cognitive cortical activation, functional connectivity of brain regions, small-world attributes and microstates were analyzed in senile deafness with or without depression at the brain imaging level.
PoZibio™ capsules contains Lactobacillus paracasei which has been heat-killed (post-biotic). The researchers will recruit a cohort of middle aged and older adults (>50 years) who will be randomised into PoZibio™ (2 x capsules daily) or placebo (2 x capsules daily) supplementation for 6 weeks. Subjects will be asked to take both capsules in the morning with their breakfast. The placebo will be matched to the active product by taste and texture. Electroencephalography (EEG) shall be combined with 3 psychological tasks, to measure a variety of cognitive domains including attention, processing speed, accuracy, and response inhibition. These psychological tasks shall include the Stroop task, the Go/No-go task, and the Flanker task. Before taking part in the psychological tasks, participants shall be required to have their EEG resting state recorded, requiring them to participate in an Eyes Open/Closed Task. The Mini Mental State Exam (MMSE) questionnaire shall be used as a digital screening tool to assess global cognitive function in participants both prior to and following the 6-week PoZibio trial. The geriatric depression scale (GDS) shall also be used as a digital screening tool to assess for depressive symptomatology in older adults. The EQ-5D questionnaire shall be used to obtain an overall profile of the health state and quality of life of participants before and after the trial. The researchers will collect venous blood samples for the investigation into the chemical composition using metabolomics, the quantification of short chain fatty acids as well as clinical biochemistry, before and after the trial. Aim: A randomised, placebo controlled parallel human clinical trial of heat-treated Lactobacillus paracasei (post-biotics) in healthy middle aged and older subjects is proposed, to assess the potential for clinically relevant benefits in terms of cognitive function.
The goal of this clinical trial is to test 6 months of aerobic exercise in older adults who are 65 years or older and have mild cognitive impairment (MCI) or probable/possible mild Alzheimer's Disease. The main questions it aims to answer are: - test the effects of aerobic exercise on aerobic fitness, white matter hyperintensity (WMH) volume, and patient-centered outcomes; - identify the best exercise to improve aerobic fitness and reduce non-responses over 6 months; and - examines the mechanisms of aerobic exercise's action on memory in older adults with early AD. Participants will receive 6 months of supervised exercise, undergo cognitive data collection and exercise testing 5 times over a year span, have an MRI brain scan 3 times over a one-year span, and have monthly follow-up discussions on health and wellness.
The goal of this feasibility study is to investigate the feasibility of a personalized naturalistic Virtual Reality scenario by assessing motion-sickness effects, engagement, pleasantness, and emotions felt considering a sample of individuals with cognitive impairment resident at the Azienda Pubblica di Servizi alla Persona (APSP) "Margherita Grazioli", a long-term care home in Trento (Italy) in collaboration with the Department of General Psychology - University of Padova (Italy) and the Centre for Health and Wellbeing-Fondazione Bruno Kessler (Italy). The current proof-of-concept and feasibility study is a one-session single-centre trial based on a mixed-methods approach inspired by the Obesity-Related Behavioral Intervention Trials (ORBIT) framework for the design (Phase Ib) of digital interventions and their preliminary testing (Phase IIa).
This research aims to investigate whether the use of music-improvisation therapy for older adult participants can lead to improvements in cognitive ability levels, especially in attentional functions. Very relevant reviews highlight studies that demonstrate the effectiveness of Music Therapy training. However, only a few are based on randomised criteria and structured methodological approaches. This affects the generalizability of findings, as to whether Music Therapy interventions are effective in improving cognitive functions, mood, and quality of life of people with cognitive decline. In order to make a difference, there is a need for more studies that are structured [i] according to rigorous empirical criteria (namely involving random assignment of participants to activity groups), [ii] and that gather scientific evidence, based on both standardized cognitive tests and biomarkers (hormones: Cortisol, or stress hormone, and DHEA or aging hormone; brain signal, EEG; Physiology: Respiratory Sinus Arrhythmia). In this RCT study, the investigator investigated the effect of 4-month music therapy vs Storytelling program for older adults with cognitive decline, living in care homes.
Rationale: Individuals with spinal cord injury (SCI) suffer from accelerated cognitive aging. In able-bodied individuals, a vast amount of studies have shown that exercise interventions can improve cognitive function. Myokines (i.e. factors released into the blood stream from muscle cells) are considered one of the mediators of this beneficial effect. Neuromuscular electrical stimulation (NMES), used to replace or support muscle training in disabled individuals with poor exercise possibilities, was shown to elicit a large release of myokines (in some studies larger than following voluntary exercise). However, so far, the effects of NMES on cognitive function have never been studied before. In fact, only one study has previously investigated the effect of exercise on cognitive function in persons with SCI. Objective: The primary aim is to assess to what extent a 12 week intervention with NMES to the quadriceps muscles of people with SCI can change their performance on a set of cognitive tests. Secondarily, the investigators will measure to what extent NMES to the quadriceps muscles of people with SCI induces changes in blood levels of the myokine brain-derived neurotrophic factor (BDNF), which is considered a potential mediator of the exercise-cognition effect, facilitating neuroplastic processes. Study design: A single case experimental design (SCED) with sequential multiple baseline time series and a single-armed prospective study design, with a random duration of the baseline phase ranging from 3 to 6 weeks, an intervention phase of 12 weeks, and a 12 week period without measurements, followed by a follow-up phase of 3 weeks; in addition to a single-armed prospective study design. Study population: Individuals (n = 15) aged 18 years and older with a chronic SCI (>1y post-injury) and with visible or palpable contraction of the quadriceps muscles upon NMES will be recruited at the rehabilitation centre of Adelante in Hoensbroek, the Netherlands. Intervention: The study participants will receive 30min of NMES using surface electrodes on the quadriceps muscles three times per week for a total duration of 12 weeks. Main study parameters/endpoints: The primary outcome is cognitive function changes which will be measured using a secured smartphone application (e.g. m-Path). Secondary outcome measures are changes in the blood myokine levels of BDNF and changes in cognitive outcome scores on an verbal cognitive test battery.
The purpose of this study is to develop and test a comprehensive Brain Health Together program for older adults living with cognitive decline.
Subjective cognitive decline-SCD is a subclinical cognitive impairment subjectively experienced without being detectable from a diagnostic and neuropsychological perspective. It can negatively impact on patient's frailty and quality of life and it may be prodromal to severe cognitive impairment. Currently, only a few screening tools focusing mainly on memory complaints exist. The aim of this study is to analyze if a new screening tool called MASCoD (Multidimensional Assessment of Subjective Cognitive Decline) can detect and monitor the SCD, predicting the risk of developing severe cognitive decline over time. Specifically, the investigators have the following aims: primary objectives: 1. To assess the construct validity and tune the clinical cutoffs of the new instrument through the correlation of MASCoD scores with neuropsychological evaluation and brain 18F-FDG-PET. 2. To assess the clinical validity (predictive capability) of the new instrument through a classification model (dependent variable: brain 18F-FDG-PET examination; independent variable: MASCoD; control variables: gender, age and neuropsychological evaluation). Secondary objective: To evaluate the suitability of MASCoD as tool for the monitoring of patients over time. Specifically, the investigators want to evaluate if the MASCoD score is able to assess the effects of a cognitive treatment and, in turn, to identify outpatients who most likely will benefit from it. After the multidimensional evaluation at T0, the participants will be randomly allocated into an experimental group and a wait list control group. Specifically, cognitive training will be offered by means of technological devices (Neurotablet). At T1, all outpatients (experimental group and wait list control group) will be evaluated through MASCoD and the extensive neuropsychological evaluation for the second time.
The purpose of this study was to analysis the incidence of ear symptoms, cognitive function decline and emotional disorders in Chinese people who were infected with COVID-19, exploring the impact of COVID-19 on the auditory system, cognitive function and emotional function, and analyzing the changes in functional connectivity of brain network after COVID-19 infection.
HELI is a multicenter, randomised controlled trial in two Dutch research centres (Donders Centre for Cognitive Neuroimaging, Nijmegen, and the department of Human Nutrition & Health at Wageningen University) among 104 older adults aged 60-75 years who are at risk for cognitive decline with an intervention duration of 26 weeks (roughly 6 months). Participants are randomized in a 1:1 ratio to a multidomain lifestyle intervention characterized by group-sessions and guidance (high-intensity intervention group) versus online access to general lifestyle-related health information in the form of biweekly leaflets (low-intensity intervention group).
