This study is designed to to test the technical feasibility of encouraging interaction with a mobile smartphone software package (mHealth app) for training aspects of executive function and cognition.
- Based on research showing that cognitive-motor training programs help improve cognition in older adults with mild cognitive impairment, this program uses an interactive system to combine cognitive training with exercise. - The interactive system consists of wearable sensors and has the advantage of cognitive training without space constraints, and the cognitive training program consists of a total of five developed cognitive training games. - The program is expected to improve the cognitive abilities of the elderly and improve their physical abilities.
This project will develop and test the effects and mechanisms of a music improvisation training intervention on self-regulation of older adults with and without MCI. The investigator's overall hypothesis is that improvisation training will lead to improvements in self-regulation, compared to controls, and that improvisation training will be associated with specific changes in prefrontal brain networks and ultimately cognitive engagement.
Using a Virtual Reality (VR) games-based application is as an innovative falls prevention technology in an aged care service. The VR intervention has promising effects on improving the physical and balance performances in the older adults.The study explored and evaluated the effects of VR activity-based training on falls prevention among community-dwelling older adults with mild cognitive impairment.
Population aging in Portugal has led to problematic social issues (American Psychiatric Association, 2013; Spector, Woods & Orrell, 2008; Wimo & Prince, 2010). At the same time, there is a noticeable increase in the prevalence of Neurocognitive Disorders (NCDs), commonly referred to in clinical practice as mild cognitive impairment and dementia (Apóstolo, Cardoso, Silva & Costa, 2014; Apóstolo & Cardoso, 2014). NCDs can be classified based on the degree of cognitive decline, ranging from mild to major, and based on etiology, which includes Alzheimer's disease, Vascular dementia, Lewy body dementia, Frontotemporal dementia, and others (American Psychiatric Association, 2013). In the European context, Portugal is among the minority of countries that do not have an official strategy for the care of people with mild cognitive impairment and dementia. Therefore, it is imperative to define national health policies that address the identified needs (Knapp et al., 2006). Currently, non-pharmacological interventions, such as Individual Cognitive Stimulation (ICS), are gaining relevance as treatment responses to the aforementioned syndromes, due to the increasing clinical, social, and economic impact of mild cognitive impairment and dementia (Aguirre, Hoare, Spector, Woods, & Orrell, 2014; Apóstolo et al., 2014). ICS can be considered the implementation of a set of meaningful activities, carried out over several sessions, usually in a social context, with the aim of stimulating various domains, including attention, thinking, language, memory, and calculation (Aguirre et al., 2012; Apóstolo et al., 2014; Yates, Orrell, Spector & Orgeta, 2015). Current evidence supports the effectiveness of this intervention, indicating that ICS programs are associated with health benefits, particularly in cognition, mood, well-being, functional activity, quality of life, and communication skills (Apóstolo et al., 2014; Yates et al., 2014). Providing care to people with mild cognitive impairment and dementia poses a challenge for the healthcare system, necessitating the implementation of specific interventions to increase self-care potential, autonomy, adaptation, and coping with deficits, as well as empowering the family and/or support network (Alzheimer Europe, 2013; Orrell et al., 2012; Woods, Aguirre, Spector & Orrell, 2012; Yates et al., 2015). Due to the global pandemic context of SARS-CoV-2, social care institutions for the elderly underwent changes in their dynamics. One of the measures implemented during the emergency plan was the closure of adult day care centers. The elderly who previously attended these social care facilities are now staying in their own homes or with family/informal caregivers, thus being deprived of the social and cognitive stimuli they were accustomed to. The mobilization of this population to their homes has led to increased social isolation and loneliness, which are underestimated public health risks. These factors affect a significant proportion of the elderly population and can lead to cognitive decline, feelings of loneliness, sadness, and abandonment, which were previously alleviated by the social care centers (National Academies of Sciences, Engineering, and Medicine, 2020). Given the described situation, the Making a Difference 3 program - an ICS program - represents an excellent implementation option, as it can be developed in various contexts, including the home environment, using cost-effective resources, addressing many of the needs of both individuals with cognitive impairment and their informal family caregivers. In summary, in Portugal, there is no established practice of implementing structured ICS interventions with individual sessions for use in the home environment. Thus, there is a need for the MD3 program to be disseminated to promote best practices. In response to the needs arising from the current pandemic context, the team of this project aims to produce national evidence on the effect of ICS in individuals with mild cognitive impairment and dementia, in the home environment of the elderly person, managed by informal caregivers and supervised by healthcare professionals.
to assess executive network using resting-state fMRI and patterns of brain activation using task fMRI with a cognitive paradigm, against the background of taking the drug in comparison with placebo in patients with post-COVID asthenic syndrome.
For this study, 213 individuals with Mild Cognitive Impairment were recruited. The study period ran from June 2018 to October 2021. The procedure involved a combined screening and baseline examination, including oral, medical, cognitive, and quality-of-life examinations. Re-examinations followed this at 6, 12, and 24 months. The examinations were performed at a university research clinic, and all participants received their usual medical and dental care during the study. At baseline, each participant received a powered toothbrush. Participants were carefully instructed on how to operate the powered toothbrush and were asked to brush for at least two minutes in the morning and evening. No restrictions were given against the use of other oral care products. Compliance with the powered toothbrush was followed by a participant survey conducted at each examination.. Facilitating and improving life by introducing a powered toothbrush as part of oral hygiene may benefit individuals with MCI. This study aimed to investigate whether the use of a powered toothbrush could maintain or improve oral health by reducing dental plaque (PI), bleeding on probing (BOP), and periodontal pocket depth (PPD)≥4mm in a group of individuals with MCI for an observation period of 24 months. Furthermore, to study how oral health changes affect QoL aspects.
This study conducted a retrospective analysis of 64 patients with mild cognitive impairment of the kidney deficiency phlegm and stasis type who underwent treatment with Naohuan Dan combined with Idebenone. The patients' cognitive function was evaluated using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) before and after treatment. Daily living abilities were assessed using the Activities of Daily Living (ADL) scale, depression status was evaluated using the Geriatric Depression Scale (GDS), and the severity of Traditional Chinese Medicine (TCM) syndrome was assessed using the TCM diagnostic scale. Peripheral blood from the patients was also collected for analysis of neuron-specific enolase (NSE) and inflammatory factors. The aim was to evaluate the safety and feasibility of using Naohuan Dan combined with Idebenone for the treatment of mild cognitive impairment of the kidney deficiency phlegm and stasis type.
The purpose of this research is to examine whether and to what extent training of different types of cognitive engagement will improve performance on fluid cognitive abilities that typically decline with age. The research covered by this protocol will use behavioral data that yield response latencies and accuracies of the untrained tasks, and brain activations in fMRI tasks, to test specific hypotheses about neural plasticity and cognitive plasticity from these engagement techniques. Hence, human subjects will be employed in an experiment lasting for 20 hours spanning over 2 months where they will either receive real-time strategy-based videogame training or crystallized intelligence training. In addition, long-term retention data will be obtained after 6 month post-training to investigate any long-term benefits.
