Active clinical trials for "Lewy Body Disease"

The general aim of this research project is to determine the relationships between alterations of central cholinergic (ACh) and dopaminergic (DA) systems and neurobehavioral features of dementias with Lewy bodies (DLB). Both clinical and neurochemical data support the view that DLB is not a homogeneous entity and it can be hypothesized that differential alterations of central ACh systems (i.e. anterior vs posterior vs striatal interneurons) in association or not with a DA nigrostriatal dysfunction could partly support the clinical heterogeneity observed in this disease. ACh in vivo imaging has been relatively underutilized to date and to our knowledge only on the postsynaptic side. Furthermore, ACh/DA interactions and their relationships with the symptomatology of DLB and related pathologies (PDD) had never been investigated.

This study evaluates the effect and process of individualized music therapy for home-dwelling persons with mild to moderate dementia. The music therapy is administered individually and includes a close caregiver. Memory of familiar music is found to be retained in persons with dementia. It is assumed to facilitate autobiographical memories and stimulate interaction with significant others. Based on time series analyses we will use statistical process control to evaluate when and how change occur.

In this Phase II SBIR project we will enhance a wireless WiFi-based insole that was designed and successfully tested during a Phase I trial with elderly persons with dementia and their caregivers, and then investigate its efficacy in terms of caregiver activity, burden, and quality of life in Phase II. Evaluation will use semi-structured interviews and participant observation data collected from professional and family caregivers of patients with moderate or mild dementia.

This study seeks to evaluate the efficacy and safety of NA-83 in subjects with mild cognitive impairment due to Alzheimer's Disease

Dementia with Lewy body (DLB) is the second most common neurodegenerative dementia in autopsy series. However, DLB represents a small proportion of the clinical diagnoses in epidemiology registries. Indeed Alzheimer disease (AD) and DLB are often concomitant, they share many symptoms and only a small weight is given to non-motor symptoms in DLB diagnosis. DLB is at the end of a pathological spectrum overlapping with AD, explaining the poor diagnostic value of both diagnostic criteria. To date there is still a need for a tool able to discriminate patients with pure DLB from those expressing common signs with both AD and DLB and those with pure AD. The purpose of this study is to validate a semi quantitative scale designed to reflect the Lewy Bodies burden in patients with mild to moderate cognitive decline. The investigators hypothesized that the score obtained may differentiate between AD, DLB and patients fulfilling clinical criteria for both DLB an AD. This score could also be correlated with dopaminergic depletion assessed with [18F]fluorodopa PET/computed tomography and/or with potential biomarkers of ADD measured in cerebrospinal fluid. This clinical validation is a preliminary work preceding further studies correlating the LeSCoD score with functional imaging features, prognosis and therapeutic response. Thus, the expected outcomes involve an improvement in demented patients' care, as well as a better patient selection for further therapeutic studies

This study is a feasibility randomized controlled trial (RCT) for an evidence-based intervention for people with moderate to severe dementia in Hong Kong. The psychosocial intervention is adapted from Cognitive Stimulation Therapy (CST), translated and adapted for the Hong Kong Chinese population, and developed within the Medical Research Council (MRC) framework.

Dementing syndromes are, for the most part, incurable. People with dementia become highly dependent and frequently have to move from their homes into residential aged care facilities. Medications aimed at reducing the severity of a number of symptoms associated with the different types of dementia have had only modest success. Increasingly, people with dementia, their families and carers are turning to supplementary or alternative approaches to the management of their symptoms. There are many published reports describing the successful use of music therapy in reducing the severity of many symptoms of dementia. These include reports of improved memory, improved language skills, reduced anxiety and depression, reductions in agitation and disruptive behaviours and better social relationships with family, peers and carers. However, the quality of evidence they provide for the most part fails meet the standards of evidence required by health care providers. This clinical trial will examine the effects of a music therapy intervention. The study will recruit 180 patients in sub-acute hospital wards. Participants will be randomly placed in groups that receive either occupational therapy or music therapy. Before the therapy programs begin, we will use questionnaires to measure memory function, language ability, orientation and mood. We will also record brain activity from the surface of the scalp, blood pressure and pulse to examine physiological responses. The same measures will be repeated after the 3 weeks of therapy to determine whether there has been any improvement in the symptoms of the participants and whether the group that had music therapy showed greater improvement than the group that had occupational therapy. We will make a video recording during one therapy session to allow us to observe levels of engagement and to assess changes in facial expressions. This will provide information about the immediate effects of music on mood and social interaction. The information we collect about brain activity and blood pressure will help us to understand how music therapy might bring about changes in the symptoms of dementia. This understanding will be useful in developing better applications of music therapy. It will also add to our current knowledge about how the various diseases cause the problems they do. In summary, the primary aim of the project is to determine whether the reported effects of music therapy are supported by objective evidence.

The investigators aim to study the effects of a 24-week remote-based resistance exercise training program on cardiovascular disease risk factors, cognitive function, and quality of life in older adults living with mild cognitive impairment or Alzheimer's Disease and/or a related dementia. Data for this study will be collected at the beginning, middle, and end of the resistance training program. Participants of this study will receive a baseline health-fitness assessment at the beginning of the study. Measurements of resting blood pressure, fasting blood glucose and lipids, waist and hip circumferences, height and weight, cognitive function and quality of life will be collected at the health-fitness assessment. Participants will then receive supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a second 12-week health-fitness assessment in the middle of the intervention. Participants will then receive 12 additional weeks of supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a third 24-week health fitness assessment at the end of the study.
