Filter by:Neuropathologically, Parkinson disease (PD) is characterized by the accumulation of intra-neuronal protein aggregates (Lewy bodies and Lewy neurites). It is believed that altered rt-synuclein protein handling plays a key role in the etiopathogenesis of PD, because it is the principal component of Lewy pathology. Recent evidence now suggests the possibility that a-synuclein is a prion-like protein and that PD is a prion-like disease. Some studies have suggested that environmental toxins promote the release of a-synuclein by enter- ic neurons and that released enteric a-synuclein is taken up by presynaptic sympathetic neurites and retro- gradely transported to the soma, where it accumulates, thus mediating the progression of PD pathology. These data indicate the precocity of autonomic nervous system involvement with reference to further spread of a-synuclein pathology. We have evidence from a previous study that the vagal preganglionic pro- jections to the gut express a-synuclein, thus providing a candidate a-synuclein-expressing pathway for the retrograde transport of pathogens to the central nervous system. Cardiovascular autonomic dysfunction explores the reactivity of sympathetic and parasympathetic pathways to a predefined set of tests, allowing to quantify the degree of dysfunction in each of the two components of the autonomic nervous system. Mutations in the GBA gene influence the risk for dementia in PD 21; this effect of GBA is not synergistic with that of increasing age. Heterozygous GBA mutations are considered an important risk factor for PD and dementia, possibly causing a wider protein accumulation in the brain. In vitro models of alpha-synuclein aggregation have provided evidence for co-localization with mutant GBA . It has been proposed that a gain of function mechanism operates in patients with PD carrying GBA gene mutations, whereby mutant G8A promotes alpha-synuclein aggregation, accelerating Lewy body formation and neuronal loss. Each of the selected variables provides a unique window to ascertain the association between PD patho- physiology and the risk of related dementia. Our hypothesis is that PD patients who develop incident dementia will have a number of statistically different abnormalities that will be evidenced as individual predictors and will also be assembled into a predictive algorithm. This project addresses a key issue in Parkinson disease, a progressive neurodegenerative condition, related to the assessment of variables associated to the development of dementia. The project is focused on dementia as a significant and important clinical milestone that constitutes the main cause of non-reversible functional impairment in PD patients.
Music therapy has received more attention with its surging application in neuro-rehabilitation overseas. Given the dearth of music therapy and cognitive rehabilitation research conducted in Malaysia, this pilot study intended to investigate the effect of active and passive music therapy interventions versus the standard care condition in cognition among adults with neuro-rehabilitation needs.
Dementia, which leads to deterioration in cognitive and behavioral functions, is a chronic progressive disease. Since the diagnosis is made, the care needs of the patients increase. In the later stages of the disease, it becomes completely dependent on the caregiver. they are coming. Caregiving is performed by family members in developing countries such as Turkey. Family members face many difficulties in their social, work, and daily lives after they start to care. These difficulties are the burden of caregiving is called. Caregivers who perceive the burden of care also experience anxiety, stress, and depression. Jacobson progressive muscle relaxation in coping with these problems exercises can be used. This study was planned to examine the effects of progressive muscle relaxation exercises on anxiety, stress, depression, and caregiver burden in dementia caregivers.
Digital medicine is a useful clinical resource for people with cognitive disorders. Scientific literature has shown that in people with dementia neuropsychological instruments administered in remote are characterized by high psychometric quality and satisfaction levels. However, evidence about the reliability of remote neuropsychological domain-specific tests is still limited in the Italian context. The principal aims of the study will be 1) to evaluate the reliability of the remote administration of neuropsychological screening and domain-specific tests compared to the face-to-face administration in patients with cognitive disorders; 2) to assess the feasibility and level of satisfaction of patients and caregivers about remote administration. All participants will be submitted to both face-to-face and remote neuropsychological assessment (by videoconference) in a counterbalanced cross-over design. Finally, all patients and/or caregivers will complete a satisfaction questionnaire about the remote administration.
The goal of this clinical trial is to evaluate the feasibility and acceptability of online psychoeducation in the family caregivers of people with dementia living in the community. The main objectives it aims to answer are: 1. Is online psychoeducation feasible and acceptable to family caregivers of people with dementia? 2. What is the preliminary effect of online psychoeducation on caregiving self-efficacy in family caregivers of people with dementia?
The goal of this clinical trial is to explore the effectiveness of mindfulness-based VR could enhance depression, sleep quality, and overall quality of life for family caregivers providing care for people with dementia. Participants will be ask to attend the six-week course encompassed various mindfulness practices, including breathing observation, body scanning, mindful yoga, mindful walking, holistic meditation, and non-selective awareness practices. The control group will only be given the mindfulness-based audio files for six weeks.
This pilot study was designed to evaluate the effects of Individualized music listening (IML) implemented on older adults with mild cognitive impairment (MCI) and PwD. This quasi-experimental study used convenience sampling where thirty-two elderly individuals were recruited from five community-based dementia care centers then assigned to experimental (EG, n = 16) or control (CG, n = 16) groups according to the self-reports of importance of music in their lives and according to their personal wishes. The EG received eight treatments of IML (two times per week, 20 minutes per time), while the CG received the usual activities of the care centers for four weeks when EG received IML. The anxiety levels of both groups were investigated before and after first time IML and after eighth time IML. The researcher observed positive and negative behaviors of EG before, during and after each IML per 20 minutes in each time IML.
To observe the clinical efficacy of TCM acupuncture combined with western medicine nimodipine for prevention of post-stroke dementia by comparing with clinical conventional treatment methods.
The goal of this observational study is to explore the optimal dose of computerized cognitive training in patients with cognitive impairment. The main questions it aims to answer are: - Is there an optimal dose of computerized cognitive training for patients with cognitive impairment? - Is the optimal dose different in patients in different age populations? Participants enrolled in the study took a reported computerized cognitive training program and the training data were analyzed for exploring the optimal dose. The researchers will compare the different dose groups to see if there is an optimal dose for the highest improvement in cognitive abilities. The researchers will additionally compare two age groups (aged younger than 60y or aged 60y and older) to see if the optimal doses in the two groups are different.
The goal of this study is to examine the effects of auditory beat stimulation on anxiety in patients diagnosed with bvFTD. Main aims are: - to ascertain whether anxiety in bvFTD patients can be modulated using auditory beat stimulation - to investigate patterns of anxiety and mind wandering in bvFTD patient population Patients were asked to complete a number of questionnaires relating to well-being and mind wandering, as well as to listen daily to audio files of beat stimulation.
