NCT05544201
Background: Sleep disturbances are highly prevalent in ageing population and patients with age-related neurodegenerative diseases, which severely affect cognition and even lead to accumulated amyloid-β (Aβ). At present, non-pharmacological interventions for sleep disturbances in dementia patients are accepted as first line of treatment, of which the evidence from clinical trials is very limited. Encouraging results from recent studies on transcranial direct current stimulation (tDCS) showed moderate positive effects on sleep quality in preclinical Alzheimer's disease (AD). Compared to tDCS, high-definition transcranial alternating current stimulation (HD-tACS) enables the entrainment of neuronal activities with optimized focality through injecting small electric current with a specific frequency and has significant enhancement effects on slow wave activities. Objectives: The investigators aim to 1) investigate and compare the safety, efficacy and sustainability of 40 Hz HD-tACS and HD-tDCS over left dorsolateral prefrontal cortex (DLPFC) in mild neurocognitive disorder due to AD (NCD-AD) patients with sleep disturbances; 2) examine the relationship between the changes in sleep quality, cognitive function and saliva Aβ levels. Methods: Chinese right-handed mild NCD-AD patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 4-week intervention of either HD-tACS, HD-tDCS, or sham HD-tCS, with 33 participants per arm. Before intervention, structural magnetic resonance imaging (MRI) data is used to construct individual realistic head model. Comprehensive assessments, including sleep quality, cognitive performance and saliva Aβ levels will be conducted at baseline, 4th week, 8th week, 12th week and 24th week. Program adherence and adverse effects will be monitored throughout intervention. Data analysis: The primary outcomes will be the changes in sleep quality and memory performance with modality-driven paradigms (HD-tACS, HD-tDCS, sham HD-tCS), and comparisons of group differences across different time points. Secondary outcomes will be the changes objective sleep pattern, global cognition, saliva Aβ levels and quality of life. Intention-to-treat analysis will be carried out. Changes of efficacy indicators from baseline to each follow up point will be tested with mixed effect model. Significance: This study aims to investigate the feasibility, safety and efficacy of HD-tACS and HD-tDCS over left DLPFC for sleep disturbances and cognitive dysfunction in mild NCD-AD patients. It wills also test the program adherence, tolerability and adverse effects of this innovative neurotechonology. Information will be helpful for in-depth understanding the relationship of "sleep disturbances-amyloid deposition" and guiding the further studies of sleep medicine and neurodegenerative diseases.

NCT04498650
This is a phase 2B multicenter, randomized, double-blind, placebo-controlled, parallel group dose finding study to evaluate the safety, tolerability and efficacy of PQ912, an inhibitor of the glutaminyl cyclase enzyme, in 250 subjects with mild cognitive impairment and mild dementia due to Alzheimer 's Disease.
NCT06078332
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.

NCT03633253
The overall objective of the proposal is to examine the epidemiology of the newly reported "motoric cognitive risk" (MCR) syndrome, which is a pre-dementia syndrome combining subjective cognitive complaint (i.e.; memory complaint) with objective slow gait speed, in the Quebec elderly population. Cognition and locomotion are two human abilities controlled by the brain. Their decline is highly prevalent with physiological and pathological aging, and is greater than the simple sum of their respective prevalence, suggesting a complex age-related interplay between cognition and locomotion. Both declines in cognition and locomotion are associated, furthermore the temporal nature of their association has been unclear for a long time. Recently, a systematic review and meta-analysis has provided evidence that poor gait performance predicts dementia and, in particular, has demonstrated that MCR syndrome is a pre-dementia syndrome, suggesting that low gait performance is the first symptom of dementia. The uniqueness of MCR syndrome is that it does not rely on a complex evaluation or laboratory investigations. Indeed, this syndrome combined subjective cognitive complaint and objective slow gait speed, and is easy to apply in population-based settings. Prevalence and incidence of MCR syndrome, as well as its association with incidence of cognitive decline and impairment, have never been reported in Canada. Nutrition as a determinant of successful aging: The Quebec longitudinal Study (the NuAge study) is a Quebec population-based observational cohort study performed in healthy older community-dwellers adults which provides a unique opportunity to: 1) obtain reliable estimates of MCR syndrome prevalence and incidence, 2) determine the distribution of clinical characteristics associated with MCR syndrome, 3) examine the association of MCR syndrome with cognitive decline and incidence of cognitive impairment in the Quebec elderly population.

NCT03255967
Alzheimer's Disease and Related Disorders (dementia) poses a significant challenge to our public health. While many persons with dementia are cared for by friends and family in the community with the assistance of home healthcare, most home healthcare clinicians and agencies are ill prepared to care for this population and therefore have difficulty assisting patients and caregivers in maintaining quality of life leading to adverse patient outcomes, increased caregiver stress and burnout, and healthcare utilization. This study will therefore utilize a cluster randomized controlled design at 3 study sites to examine the ability of a multi-component evidence-based practice primary palliative care quality improvement program for home healthcare registered nurses, occupational therapists and physical therapists to improve the quality of life and reduce healthcare utilization for persons with dementia and their informal caregiver.

The music therapy intervention takes place once a week for 6 weeks via telemedicine, with the first session reserved for music therapy intake/assessment. There are 5 additional visits, once per week. The format of the sessions may include: a greeting song to orient the participant to the start of the session; singing of 1-3 preferred/chosen songs to address cognition and communication; two movement songs with instrument playing interventions to stimulate cognition and movement; songwriting for self-expression, cognitive, and emotional support; relaxation/mindfulness; a closing song to help the participant transition at the completion of the session, The music therapist also provides training to caregivers in techniques to utilize music for behavioral support. Twelve participants and their care partners will be randomized to receive a personalized music CD that they keep and can listen to as they wish.
NCT04710550
The overall objective is to obtain an initial assessment of the value of using \[18F\]3F4AP for imaging demyelinating diseases such as traumatic brain injury (TBI), neurodegenerative diseases such as mild cognitive impairment (MCI) and Alzheimer's Disease (AD): * Aim 1) Assess the safety of \[18F\]3F4AP in healthy volunteers and subjects with traumatic brain injury (TBI) and neurocognitive impaired subjects (AD/MCI). Hypothesis 1: Administration of \[18F\]3F4AP will result in no changes in vitals or other adverse events. * Aim 2) Assess the radiation doses to the main organs in healthy volunteers. Hypothesis 2: the radiation doses to each organ will be comparable in all subjects and within the acceptable limits. * Aim 3) Assess the pharmacokinetics of a bolus infusion of \[18F\]3F4AP in humans including healthy volunteers and patients. Hypothesis 3: the pharmacokinetics of \[18F\]3F4AP at the whole brain level will be similar in controls, TBI and AD/MCI subjects. The kinetics in demyelinated lesions will be slower than in healthy areas. * Aim 4) Correlate MR images with \[18F\]3F4AP PET images. Hypothesis 4A: all the lesions seen on the MRI will show increased signal (VT or SUV) on the PET images. Hypothesis 4B: some of the lesions on the MRI will show increased signal (VT or SUV) on the PET but not all. * Aim 5) Correlate \[18F\]3F4AP PET signal with neuropsychological testing in people with TBI and AD/MCI. Hypothesis 5A: increased PET signal (VT or SUV) will correlate with impaired Mini Mental State Examination (MMSE).
