Filter by:This study will compare the discriminative power of [18F]-SynVesT-1 PET and the standard-of-care [18F]-FDG PET in different cognitive disorders (Alzheimer's disease, Frontotemporal degeneration, dementia with Lewy bodies and late-life psychiatric disorders). Moreover, changes in [18F]-SynVesT-1 PET will be evaluated as well as their correlation with specific symptomatology.
Double blinded, sham-controlled, randomized trial on repeated transcranial alternating current brain stimulation (tACS) in neurodegenerative diseases. The investigators will evaluate whether a 4-times daily repeated stimulation with gamma tACS on the posterior parietal cortex can improve symptoms in patients with neurodegenerative diseases, including dementia with Lewy Bodies, Alzheimer's disease, idiopathic normal pressure hydrocephalus and Frontotemporal dementia.
This research focuses on the activity of an enzymatic protein: glucocerebrosidase, in dementia with lewy bodies (DLB). Indeed, the mutation of the GBA gene responsible for a decrease in the activity of glucocerebrosidase is the most frequent known genetic risk factor in DLB. However, mutations of the GBA gene are known in another pathology, Gaucher disease, in which treatments have been developed. The objective of this research is to determine if glucocerebrosidase activity is decreased in DLB. This hypothesis could open up a therapeutic perspective, with treatments already used in Gaucher disease.
Multi-center, randomized, double-blind, placebo-controlled, 6- month study in subjects with mild to moderate Dementia with Lewy Bodies.
The purpose of this study is to learn more about the effectiveness of palliative care training for community physicians and telemedicine support services for patients and carepartners with Parkinson's disease and Lewy Body Dementia (LBD) or related conditions and their care partners. Palliative care is a treatment approach focused on improving quality of life by relieving suffering in the areas of physical symptoms such as pain, psychiatric symptoms such as depression, psychosocial issues and spiritual needs. Telemedicine is the use of technology that allows participants to interact with a health care provider without being physically near the provider.
Brain oscillations are ubiquitous in the human brain and have been implicated in cognitive and behavioral states defined in precisely tuned neural networks. In neurodegenerative disorders, neurodegeneration is accompanied by changes in oscillatory activity leading to the emerging concept of neurological and psychiatric disorders as "oscillopathies". Dementia with Lewy bodies (DLB), which is the second most frequent cause of neurodegenerative dementia, is characterized by an important alteration of brain oscillations. The restoration of oscillations by neuronal entrainment in animal models of neurodegenerative disease has shown a significant reduction in the neuropathological load of toxic proteins, with a consequent significant increase in cognitive performance. Transcranial alternating current brain stimulation (tACS), is a neurophysiological method of non-invasive modulation of the excitability of the central nervous system that is having an increasingly numerous spectrum of potential therapeutic applications. Recent studies have demonstrated the effectiveness of this method in modulating the natural frequencies of cerebral oscillation, underlying multiple cognitive processes such as verbal memory, perception and working memory. On the basis of these premises, the treatment with alpha tACS is proposed in patients with DLB. In this randomized, double-blind, sham-controlled, cross-over study, the investigators will evaluate whether a single stimulation with alpha tACS on the occipital lobes can improve symptoms in patients with DLB.
This study will investigate the efficacy of novel biomarkers, namely blood-based biomarkers, pupillometry and actigraphy to track and predict progression of Alzheimer's disease (AD). Furthermore, the study will investigate the diagnostic value of pupillometry and actigraphy for AD.
The present study is a monocentric, therapeutic clinical trial involving forty patients diagnosed with Dementia with Lewy Bodies (DLB). The aim of this clinical trial is to evaluate the feasibility and relevance of repetitive transcranial magnetic stimulation (rTMS); a non-invasive neuromodulation technique, with a main emphasis on the evaluation of the outcome on cognitive fluctuations. For this purpose, we will compare two distinct rTMS conditions (control and experimental) in a pre-post rTMS setting. The experimental condition will be targeting the insular cortex which has been shown to be affected at prodromal DLB stages, in the form of decreased grey matter concentration and a decreased regional Cerebral Blood Flow (rCBF hypoperfusion) [Blanc et al., 2015 ; Roquet et al., 2016 ; Roquet et al., 2017]. Furthermore, these insular alterations are correlated to cognitive fluctuations [Chabran et al., 2020]. In DLB, cognitive fluctuations are particularly pervasive and manifest in the form of alertness alterations and modifications of arousal states. Participants will repeatedly undergo a series of clinical and cognitive assessments in addition to several neuroimaging examinations, namely multimodal Magnetic Resonance Imaging (MRI) and electroencephalogram (EEG) recordings, in order to evaluate potential physiological modifications and clinical changes of symptoms, pre-/post-rTMS.
The aim of the project is to develop the first alpha-synuclein (a-syn)-specific PET tracer. The research phase will exploit ACI's proprietary MorphomerTM library and extensively optimized screening workflow. Promising PET-tracer candidates will be tested for their ability in detecting a-syn pathology in patients with a range of Parkinsonian conditions with different a-syn levels and distributions, comprising hereditary forms of PD and other synucleinopathies.
Dementia; It is a chronic syndrome characterized by a general and progressive deterioration in cognition, including memory, orientation, language, and comprehension. The prognosis of this progressive and neurodegenerative disease after diagnosis may differ between individuals. In its broadest sense, the prognosis after a diagnosis of dementia; can be defined by shortening of life span, high level of cognitive and functional loss, decrease in quality of life and increased need for care. However, the prognosis of different types of dementia is highly variable. Because it is the most common type of dementia, studies are usually on Alzheimer's disease. It constitutes 50-75% of total dementia cases. Vascular dementia is the second most common cause of dementia and accounts for approximately 15% of dementia cases. Dementia with Lewy bodies constitutes 10-20% of the total dementia patients and ranks second among degenerative dementia types. Frontotemporal dementia, which mimics psychiatric disorders and has prominent behavioural problems, and Parkinson's disease-associated dementia, which is characterized by cognitive impairment that can be added to the existing picture in Parkinson's patients, are also counted among other types of dementia. Prognosis-related data on dementia types other than Alzheimer's disease are limited in the literature. Determining the prognosis is important to support patients, anticipate long-term health problems, plan physician and healthcare provision, and support patients with dementia.In view of the lack of sufficient data on dementia types other than Alzheimer's disease, it is aimed to contribute to the literature on this subject and to determine the factors that may affect prognosis, morbidity and mortality in patients belonging to all dementia types.
