Active clinical trials for "Alzheimer Disease"

It is hypothesized that reappraising intergeneration relationships through perspective-taking will enhance the well-being of adult-child caregivers. Incorporating both psychological and social perspectives, the study makes a unique contribution to address research gaps by evaluating an integrated model of intervention for dementia caregivers. The conceptual model involves the following components: 1) relational insights; 2) self-reflection to integrate the challenges and benefits in caregiving; 3) interpersonal empathy To test the incremental value of perspective-taking reappraisals, the study involves a two-arm randomized controlled trial of 12 weeks of intervention with two conditions: 1) Reappraisal through Perspective Taking and 2) Basic Skill Building. Telephone-administered sessions are integrated with group sessions and home visits to maximize sustainability and accessibility of the intervention. One hundred fifty-four participants will be recruited and randomized. Primary outcomes are reduced depressive symptoms and enhanced psychological well-being for the caregivers. Secondary outcomes include enhanced social support for caregivers and reduced behavioral problems in the care-recipients.

General Hypothesis: hypothesize that A / A symptoms of AD follow a particular course, influenced by associated factors, and a prospective longitudinal observational study specifically evaluating A / A symptoms in patients with MA, living in an institution and at home, would provide useful data for both clinical practice and research. Specific Hypothesis: hypothesize that in patients with AD with clinically significant A / A there is a correlation between assessment of A / A severity based on specific scales of A / A and overall impression assessment of clinical improvement or worsening of these symptoms by the clinician.

Recently revised Alzheimer Disease (AD) diagnostic1described nonamnestic presentations: 1/ language presentation (logopenic progressive aphasia) 2/ visuospatial presentation (posterior cortical atrophy or PCA) and 3/ executive dysfunction. AD pathological changes may precede the clinical diagnosis of dementia of AD type for a while2. Biomarkers have been developed: biomarkers of brain amyloid-beta (Aß) (CerebroSpinal Fluid CSF concentration ßamyloid, molecular imaging with amyloid targeted PET ligands), biomarkers of neural degeneration (MRI hippocampal volume, regional metabolism as assessed by PET with [18F]-FDG) and may be used to made early detection of the neuropathology associated with AD Even if CSF biomarkers (tau, p-tau and β amyloïd are interesting to improve diagnosis of AD, they cannot provide topographic information. PET tau imaging seems to be promise to evaluate quantitative and spatial assessment of tau lesions both in AD and fronto-temporal lobar dementia. The hypothesis of the research is that it exists a different regional pattern of tracer retention across brain regions according to clinical symptoms : temporal for logopenic aphasia and occipital for posterior cortical atrophy.

In order to treat individuals with Down syndrome (DS) better and more efficiently and to gain more insights on its relation to Alzheimer's disease (AD), a comprehensive understanding is needed for its progression in the early or preclinical phase using various biomarkers. DS is a significant risk factor for the early development of AD, with plaques and tangles typically developing by age 35. A better understanding is needed of early markers of the disease in DS patients. Additionally the DS population represents a unique group - due to this elevated risk for AD - to examine biomarkers that may translate in general outside of the DS population to individuals at risk for developing late onset AD. In this proposal, the researchers will assess the longitudinal changes of various biomarkers in a cohort of individuals similar in design to the cross-sectional sectional study in the preliminary data.

A Phase 1 study designed to evaluate imaging characteristics of flortaucipir in the preclinical, prodromal and dementia phases of Alzheimer's disease.

According to the most popular pathophysiological models of Alzheimer's disease, the amyloid hypothesis, amyloid deposition is the causative event triggering a chain of other downstream events which finally lead to Alzheimer's disease and dementia. In mouse models of Alzheimer's disease, 40 Hz multi-sensory (auditory and visual) stimulation was able to reduce the number and size of amyloid plaques throughout cortex and improve cognitive performance. The primary objective of this study is to assess whether an intervention consisting of 40 Hz multi-sensory (auditory and visual) stimulation is able to reduce the amyloid load in non-demented amyloid-positive individuals. As secondary objectives, the investigators will assess whether such intervention is able to: improve the brain electrical activity, improve or slow down the worsening of Alzheimer's blood-based biomarkers, improve or slow down the worsening of cognition.

Oculomotor behavior and cognitive processing of visual information are intimately connected. AD patients show ocular movement problems. Oculomotor deficits are broad consisting mainly of different saccade metrics, altered pupil responses. and smaller and irregular eye vergence movements. Here we test an interactive eye-tracking game to improve eye motion control and thereby training cognitive behavior

The Researchers are trying to better understand if behavioral interventions can help improve memory compensation and engagement in healthy lifestyle behaviors in those with memory concerns but normal mental status exam.

Apathy, defined as a lack of motivation in behaviour, cognition and affect, is common in neurodegenerative diseases. Specific scales are available for the evaluation of apathy but it lacks objective evaluation methods. The aim of this study is to evaluate the changes in reaction time task according to the presence or absence of reward stimulation and to assess the relation between these performances and apathy scales.

Alzheimer's disease is a progressive and fatal brain disease. This study will investigate the use of far infrared radiation treatment for the disease.
