Filter by:The general objective of this randomized and longitudinal clinical study was to estimate the frequencies of ApoE variants both in the user population of the "Messengers of Peace" Residences and the "Associations of Relatives of Alzheimer's Patients" in Castile y Leon, since, due to its geographical location at the crossroads, it has received multiple genetic contributions from both northern Europe, the Mediterranean area and northern Africa. The main questions it aims to answer are: - What are the allelic frequencies of ApoE variants in the population of individuals with Alzheimer's disease in Castile and Leon? - Is there a correlation between the ApoE4 variant and the lipid profile in the blood of individuals with Alzheimer's disease in this region?
The temporal sequence of microglial activation, changes in functional and structural connectivity and the progression of neurocognitive deficits has not been conclusively clarified. To date, there have been no studies of the topographical and pathogenetic relationship between microglial activation and network degeneration. The main aim of the present study is to investigate the relationships between functional, structural MRI connectivity and microglial activation at different stages of AD in a multimodal approach. Genetic predisposition and biomarkers in blood and cerebrospinal fluid will also be taken into account in order to close the explanatory gap in pathogenesis between the known molecular pathological changes and their effects at system level in an integrative approach.
In this retrospective register study, clinically classified individuals with neurodegenerative disease from the years 2010-2021 will be verified from the clinical records from KUH and Oulu University Hospital (OUH). Based on the Finnish social security number, these individuals will be linked to the the national registers of Statistics Finland and Finnish Social and Health Data Permit Authority Findata including incomes, sociodemographic factors, education, occupation, criminal records as well as to the national registers including the bought pharmaceuticals, comorbidities and causes of death. For each study case, 10 randomly selected control cases, matched with age, sex and geographical area, will be used. The aim of the study is to examine: - 1) The prevalence of criminal and other disruptive behaviour in groups of different neurodegenerative diseases prior to and after the diagnosis - 2) Changes in employment, residency,income, and marital status prior to and after the neurodegenerative disease diagnosis - 3) Hospital diagnoses and reimbursable drugs prior to and after the diagnosis - 4) Causes of death in patients with neurodegenerative disease to study excess mortality of the patients
This study was focused on comparing the efficacy of repetitive Focused ultrasound mediated BBB opening in alzhemer's disease in increased number of treatment session and shorter intervals.
Patients with mild cognitive impairment aged 50-80 years old were recruited in Shiyan City, Hubei Province, and divided into intervention group and placebo group. They were given yeast β-glucan capsules and starch capsules, respectively, for 6 months, in order to explore whether yeast β-glucan can improve cognitive function of patients with mild cognitive impairment by regulating gut microbiota and its metabolites.
The goal of this clinical trial is to test a cell phone-based online program that provides Alzheimer's risk assessments and memory tests over a 6-month period. The main question it aims to answer is whether online software can help reduce the risk of Alzheimer's disease (AD) through digital education and tracking. Participants will visit RetainYourBrain.com to answer questions about their risk factors for AD and take online word recall and card game cognitive tests. Researchers will track progress over time and compare different strategies of Alzheimer's education to see if it is possible to protect brain health, reduce Alzheimer's risk, and improve memory function.
This study is a multi-center and cross-sectional study. Using standardized case report forms, we randomly selected suitable patients from the cognitive centers of provincial administrative units in Chinese mainland to conduct a questionnaire survey, so as to obtain relevant information about their economic burden.
Cognitive Stimulation Therapy (CST) is an evidence-based non-pharmacological group therapy shown to benefit people with mild to moderate dementia. Despite increasing availability of CST worldwide, access remains limited in the United States. This pilot pragmatic trial will embed CST referral into the standard care protocol of health care settings that serve people living with dementia in the state of Connecticut, and evaluate online delivery of CST known as virtual CST (V-CST), and assess the acceptability of V-CST to people living with dementia. The study design is a two-armed randomized embedded pragmatic clinical trial (ePCT). The trial aims to determine if cognitive decline is experienced less commonly among V-CST participants than control group members based on three widely used measures of cognition, the Montreal Cognitive Assessment (MoCA), St. Louis University Memory Screen (SLUMS), and Mini Mental State Exam (MMSE). The study population will be persons with mild to moderate dementia identified by clinicians in standard care. From this population, subject participants will be randomized to intervention and control groups. Patients randomly assigned to the intervention group will be referred by their clinical providers to participate in V-CST, and those who accept the referral will participate in the intervention.
Building on limitations of prior research, the investigators proposed to develop the Mindful and Self-Compassionate Care Program (MASC) to help caregivers of persons with Alzheimer Disease and Related Dementias (ADRD) manage stress associated with the general caregiver experience including stress stemming from managing challenging patient behaviors. MASC teaches: (1) mindfulness skills; (2) compassion and self-compassion skills; and (3) behavioral management skills. MASC also provides psychoeducation and group-based training and skill practice to facilitate skill uptake and integration within the caregiver experience and tasks.
There are very few treatments for neurodegenerative disorders, and the efficacy of these treatments is generally modest. Recent studies have shown a short-term positive effect of non-invasive neuromodulation techniques such as transcranial magnetic stimulation (TMS) in primary progressive aphasia (PPA). PPA is a clinical syndrome associated with Alzheimer's disease and Frontotemporal degeneration. The aim of this study is to compare the effect of TMS and language therapy versus language therapy and sham TMS in patients with PPA during 6 months. A prospective, randomized, controlled, double-blind and parallel clinical trial will be conducted. The changes in brain metabolism using FDG-PET, language, neuropsychiatric symptoms, and daily-living activities will be assessed. Connectivity changes using electroencephalography will also be examined. In addition, a subgroup of patients will be assessed with multimodal MRI (structural and functional), and blood biomarkers. As a result of this project, valuable information about the long-term efficacy of non-invasive brain stimulation in PPA will be obtained, as well as the mechanisms of the therapy and clinical and neuroimaging factors associated with therapy response.
