Active clinical trials for "Alzheimer Disease"

The purpose is to evaluate patients' interests (patients in nursing home). Moreover the study aims to evaluate whether an activity for which the patient is interested in, allows a better involvement and stimulation.

The purpose of this Phase 3 study is to evaluate the efficacy and safety of 3APS as an add-on therapy to most standard medication for Alzheimer's disease compared to placebo (inactive substance pill) in patients with mild to moderate Alzheimer's disease.

The object of this study is to investigate the use of linguistic deficits from speech samples for the early detection of Mild Cognitive Impairment and probable Alzheimer's disease. It will also evaluate whether the result of the Amyloid PET scan would confirm the effectiveness of a less expensive and less intrusive diagnostic technique through speech

The close homology between the central and enteric nervous system suggests that a disease process affecting the central nervous system could also involve its enteric counterpart. This has already been demonstrated for patients with Parkinson's disease but needs to be proven for Alzheimer's disease. Studies on enteric nervous system during Alzheimer's disease are indeed in low number and don't have led to definite conclusion. The investigators thus propose to realize a complete analysis of the enteric nervous systems in Alzheimer's disease by studying the presence of "tau' protein, of beta-amyloid peptide,... not only by immunohistochemical but also by a biochemical approach. This study will be realized from colonic samples.

To study the success of Oligodendrocyte progenitor cell culture project in Rajavithi Hospital to identify an unlimited clone human neuronal progenitor stem cells from the human brain in the Biomolecular Research Center. This study aims to produce the reproductive clone of neuronal development protocols and advance projects. Neuronal cells such as pyramidal cells, oligodendrocyte, and dopaminergic neuron differentiation protocol/projects for treatment of Alzheimer's disease, Multiple sclerosis, and Parkinson's disease respectively in next phase of clinical trials.

This is a Phase I, open label, randomized, 6-way crossover, pilot PK study

The purpose of this study is to learn about how trauma, posttraumatic stress disorder (PTSD), and mild traumatic brain injury that can occur during deployment affect the brain. The investigators also want to learn how PTSD and mild traumatic brain injury can affect the chance of developing Alzheimer disease later in life. The investigators will study this by using magnetic resonance imaging and positron emission tomography scans to obtain pictures of the brain.

Cognitive impairements in Alzheimer's and apparented disorders may lead to the decreased engagement in activities, spetially in moderate and advanced stages of evolution. The lack of stimulation for people with dementia is associated with the risk of challenging behaviors, depressives symptoms, sleeping disorders or faster cognitive deterioration. Those challenges may lead to the increased administration of pharmacological treatments, though the risks of neurleptics use in this population are currently known. In this context, non-pharacological interventions hold a significant place in dementia care. This research focuses on cognitve stimulation activities. More precisly, our study compares two aproaches using the reading groups. The first type (" usual " reading group) is based on the principle of stimulating those cognitive functions which dicreases with the evolution of dementia. The second (Montessori reading group) approach relies on the idea to use preserved capacities in order to compensate the cognitive impariments. The aim of our study is to compare the impact of these two non-pharmalogical interventions on non-verbal communication. The collected datas will help analyzing and understanding the internal and behavioral states of people living with dementia. Our study will also extend relfexions about cognitive stimulation groups in care institutions.

The objective of the study is to determine the effects of different anesthetic agents on cognitive function in patients with Alzheimer's disease (AD). The investigators will test the hypothesis that anesthesia with desflurane or propofol, compared to isoflurane or sevoflurane, will have less of an effect on post-operative cognitive dysfunction in patients with AD.

According to 2011 HAS recommendations, early detection of Alzheimer disease is the major objective in order to allow an earlier care and support. These recommendations strengthen general practitioner role, who plays a key role in the identification of cognitively impaired patients. HAS recommendations are the use of MMSE like test (Mini Mental State Examination) at general practitioner office. A self-screening test, without medical presence, would allow a self-administered cognitive assessment by the patient. A review of the literature about self-administered cognitive tests has been realized. The Self-Administered Gerocognitive Examination (SAGE) has been chosen. It is a brief, valid and reliable cognitive assessment tool, rated on 22 points, which allows an early detection of cognitive impairment, with a sensitivity close to the MMSE test. Nevertheless, SAGE has never been tested at home without medical supervision. In this study, the investigators will determine if SAGE scores at home correlates with MMSE scores at general practitioner office. Patients with inclusion criteria will be recruited during the general practitioner consultation and will have a clinical assessment included MMSE and clinical data collection. Then, SAGE will be given to the patient in order to be completed at home without medical supervision and send to the general practitioner.
