Filter by:This study will investigate the effects of "I-Learn cognition and behaviour" training in the care in agitation in patients with neurodegenerative diseases. This training for caregivers, aims to reduce agitation and psycho-behavioral disorders of patients living in nursing home. In addition, amount of psychotropic drugs prescribed, as well as the number of hospitalizations during the study will be assessed.
Some patients with subjective cognitive decline (SCD) progress to neurocognitive disorders (NCD), whereas others remain stable; however, the neuropsychological determinants of this progression have not been identified. The investigators objective was to examine baseline neuropsychological indicators that could discriminate between people in whom the SCD progressed to a mild or major NCD and people in whom the SCD remained stable. The investigators retrospectively included patients consulting for SCD at a university medical center's memory center (Amiens, France) and who had undergone three or more neuropsychological assessments at least 6 months apart. The relationship between domain-specific scores and the global cognitive score (GCS, as a function of final status (stable SCD vs. progression toward a mild or major NCD)) was examined using a generalized linear mixed model.
Brain 18F-FDG PET (positron emission tomography) is recognised as having a good negative predictive value in the search for a neurodegenerative origin of cognitive disorders. Indeed, a ratio of 0.1 on the occurrence of worsening cognitive disorders has been reported in case of normal brain FDG PET. However, the risk of developing objective cognitive disorders in patients with no cognitive complaints is estimated at 8% per year and the risk of developing dementia in patients with mild cognitive disorders at 22% per year. Cerebral 18F-FDG PET is a prognostic factor for the occurrence of unusual clinical manifestations (MCI) or the conversion of MCI to Alzheimer's disease, but we do not really know the impact on the longer term occurrence of cognitive impairment in patients with normal cerebral 18F-FDG PET. Only a longitudinal study will allow us to really know the true negative predictive value of a normal 18F-FDG PET scan and the factors associated with a risk of dementia in these subjects. This will allow us to better understand the prognostic impact of a normal brain 18F-FDG PET scan and to identify a sub-population that remains at risk, including in the case of normal brain 18F-FDG PET.
The progression of neurodegenerative disorders and the increasing number of elderly people intensifies the need of institutional care, which contrasts with the desire of most elderly and patients to live independently at home. The rapid evolution of assistive technology offers new possibilities in providing medical professionals preventive services in real-time. Therefore, the main focus of this study is on the individual sensors and how they can be combined to one unobtrusive system to assess the human behaviour and daily activities during day and night in an instrumented apartment in healthy participants.
It is commonly admitted that social cognition impairment, like deficit in facial emotion recognition or misinterpretation of others' intentions (Theory of Mind), are associated with social behavior disorders. This kind of disorders are observed in Fronto-Temporal Dementia (FTD), Alzheimer's Dementia (AD) and Parkinson's Disease (PD), with severe deficits in FTD and lighter deficits in AD and PD. One explanation might be that patients apply inappropriate visual exploration strategies to decode emotions and intentions of others. This study aims to test this hypothesis and further to analyse whether different patterns emerge from these pathologies.
The purpose of the study is to systematically characterize the clinical course of the progressive neuropathy and optic atrophy observe in pediatric and adult patients with biallelic mutations in the solute carrier family 25 member 46 (SLC25A46) gene.

This is a first in human study to determine the safety, tolerability and pharmacokinetics of ONO-2808 in healthy adult participants. The study will be conducted in 3 parts: Part A, a single-ascending dose part with an assessment of the potential food effects in non-Japanese adult participants; Part B, a single dose part to assess the effect of age in non-Japanese elderly participants; and Part C, a multiple-ascending dose part with ONO-2808 administered to healthy subjects.
Swallowing impairment (dysphagia) is extremely common in older adults living with dementia due to age-related changes in swallowing and other disease-specific impairments. Dysphagia is commonly managed by modifying diet textures rather than engaging in rehabilitative swallowing therapy. This means that countless people with dementia are left to eat pureed foods and drink thickened liquids, which are unpalatable and lead to malnutrition. As the disease progresses, many are transferred to nursing homes. In Canada, speech-language pathologists, who manage dysphagia, are consultants within nursing homes; therefore, swallowing therapy is non-existent. However, exercise therapy is more commonly available. Rodent models have demonstrated that physical exercise strengthens tongue and vocal-fold musculature, which are critical components of swallowing. Therefore, it is possible that whole-body physical exercise, which increases rate of respiration, will help to strengthen swallowing-related musculature in older adults with dementia. In this study, older adults (65+) with early-stage dementia will complete a 12-week physical exercise program to determine improvement of swallowing function.
