This double-blind, placebo-controlled study is designed to assess the effectiveness of, MediCane's balanced T3:C3 oil, a medical cannabis oil extracted from MediCane's balanced proprietary strain into GMP-grade olive oil, as an add-on therapy to standard of care (SoC), in reducing agitation and disruptive behaviors in subjects with dementia including probable AD.
The goal of this clinical trial is to evaluate the effectiveness of integrating Snoezelen methods with aromatherapy and personal items in reducing agitation in Arab elderly individuals with dementia. The main questions it aims to answer are: Does the combination of Snoezelen methods, aromatherapy, and the use of personal items significantly reduce agitation in elderly Arab patients with dementia compared to standard care practices? How do patients and caregivers perceive the impact of this integrated approach on the overall well-being and quality of life of the patients? Participants in this study will: Engage in sessions utilizing Snoezelen methods, a multi-sensory environment designed to deliver stimuli to various senses. Receive aromatherapy treatments with selected scents known for their calming properties. Be provided with personal items that are familiar and meaningful to them, to create a sense of comfort and security.
The goal of this clinical trial is aims to: 1. Translate and culturally adapt the Cognitive Leisure Activity Scale (CLAS) into Chinese and Conduct reliability and validity tests for the Chinese version of CLAS. 2. Investigate the correlation between cognitive leisure activity levels and cognitive function in the preclinical stage of Alzheimer's Disease (AD). 3. Clarify the regulatory mechanisms of cognitive leisure activity levels on the neural circuits of patients in the preclinical stage of AD.
Spatial navigation is a high-level cognitive function that enables humans to orientate themselves and move around in space by constructing a mental representation of the environment. It is particularly interesting because it involves numerous neural networks, linked to proprioception and vision, for example. Despite the versatility of this cognitive function, spatial navigation is little studied clinically, although changes in spatial planning and navigation strategies have been associated with many brain disorders, including Alzheimer's disease (Coughlan et al., 2018). This may be explained in view of the neuropsychological tests currently in use, which do not effectively assess spatial navigation disorders. In addition, many non-pathological parameters - in particular socio-demographic and lifestyle - (Wolbers & Hegarty, 2010; Coutrot et al., 2018) affect spatial navigation performance. Separating the pathological component from these non-pathological factors in spatial navigation can be challenging. In this context, Sea Hero Quest (SHQ) has been developed (Coutrot et al., 2018; Spiers et al., 2021) as an international-scale cognitive spatial navigation task that holds great promise for assessing spatial navigation performance during normal and pathological ageing. SHQ is a video game that implements classic tasks from the spatial cognition literature, and has enabled the trajectories of 4 million players with varied socio-demographic profiles to be collected. In addition to the direct measurement of spatial displacements, eye movements, measured by eye-tracking, provide additional information on the cognitive processes associated with visual attention. The analysis of eye movements can provide valuable information about the strategies employed by humans during spatial navigation (Zhu et al., eLife 2023). While it is well known that normal ageing and pathological ageing (e.g. in the context of Alzheimer's disease) affect performance in simple spatial navigation or visual attention tasks, the neurocognitive mechanisms involved in this deterioration remain poorly understood. The investigators hypothesise that the joint analysis of ocular and spatial traces will provide a more detailed understanding of the cognitive strategies deployed during a spatial navigation task, and therefore of these underlying mechanisms. The investigators therefore propose to jointly study the association between two complementary cognitive functions: spatial navigation and visual attention, and their relationship with normal and pathological ageing (confirmed Alzheimer's disease, plasma biomarkers and genetic risk factors for Alzheimer's disease). The joint analysis of these different signals has never been carried out as part of research into normal ageing and Alzheimer's disease.
In the current study, we will examine how two types of concentration meditation practices affect plasma biomarkers of Alzheimer's Disease (AD). We will also examine the effects of the two types of meditation practices on emotional well-being and episodic memory. Healthy adults aged 18-35 who meet all eligibility criteria will be invited to this study. Participants will be asked to engage in one week of daily meditation practice or no-intervention control task at home. They will also be asked to visit the lab twice, once before and once after the intervention, to provide blood samples to assess plasma biomarkers of AD and to complete emotion questionnaires and a memory test.
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
Leucettinib-21 First-in-Human Phase 1 Study in 4 Parts: Single (Part 1) and Multiple (Part 3) Ascending Doses, and Food-Effect (Part 2) in Healthy Subjects, and Single Dose (Part 4) in People with Down Syndrome (DS) and Alzheimer's Disease (AD). For Parts 1, 3 and 4, safety and tolerability of an oral administration of Leucettinib-21 will be assessed as primary objectives. Pharmacokinetics and pharmacodynamic biomarkers will be investigated as secondary objectives. For Part 2, the effect of high fat meal will be evaluated on the pharmacokinetics parameters after an oral administration of Leucettinib-21.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate diverse disease research using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for the major diseases of our time.
The 32 million Alzheimer's disease (AD) and 69 million prodromal AD patients worldwide contribute to a large economic burden. Effective and safe therapies that slow or prevent the progression from mild cognitive impairment (MCI) to AD are therefore of high priority. Transcranial alternating current stimulation (tACS) is a safe and patient-friendly non-invasive brain stimulation technique that serves as a potential candidate for reducing and/or slowing cognitive impairment. Application of tACS in the gamma frequency range, specifically around 40 Hz, has been studied in patients with AD and MCI due to AD. In these patients, a single session of 40 Hz tACS at the precuneus showed to improve episodic memory and to increase gamma power, as measured with electroencephalography. These findings will be replicated in the current study in patients with MCI due to AD, using magnetoencephalography (MEG) recorded before, during and after tACS. In this way, brain activity and network changes that underlie this improvement in episodic memory can be studied with greater temporal and spatial detail.
