Active clinical trials for "Alzheimer Disease"

The main purpose of this study is to investigate the existence of emotional attention impairments in Alzheimer's Disease, in correlation with amygdala and attention networks alterations. To this end, functional and structural neuroimaging will be used. A face expression recognition task, along with eyetracking, will be used to assess emotional attention impairments.

The study employs tau positron emission tomography (PET) imaging in a well-characterized multi-racial/ethnic cohort to examine the extent to which tau pathology is associated with cognition, differences in tau pathology across racial/ethnic groups, and the relationship between MRI markers of small-vessel cerebrovascular disease and tau pathology. The study also investigates amyloid-dependent tau spreading.

The main goal of the T1rho/BBRC2017 study is to assess the capability of the MRI sequences T1rho + multicomponent T2 relaxation analysis of detecting abnormal cerebral protein deposition in AD patients in comparison with an age-matched cognitively healthy control group. Both the AD and control groups will had previously undergone amyloid PET imaging to confirm/discard cerebral proteinopathy in the context of other research studies.

Cognitive and behavioral units (CBUs) have been created between 2008 and 2012 French National Alzheimer plan for the management of behavior problems of patients suffering from Alzheimer's disease or other related disorders and necessitating hospitalisation. This Alzheimer plan is promoting the evaluation of these units through the observation of the behavioral and psychological symptoms of dementia (BPSD) evolution. As these units are new, it appears important to assess their long-term impact on patients care.

The main purpose of this study is to evaluate the safety and efficacy of Huperzine A sustained release tablets in patients with mild to moderate Alzheimer's Disease.

This is an experimental medicine study to evaluate the kinetics of cerebrospinal fluid (CSF) biomarkers in subjects with Alzheimer's disease (AD) or progressive supranuclear palsy (PSP) compared to healthy controls using a heavy water (2H2O) labeling method. This study is exploring the time profile of appearance and disappearance of pulse deuterium-labeled cargo proteins in CSF of subjects with AD and/or PSP, which is different from healthy controls, due to deficits in fast axonal transport.

Photozig and Stanford University are creating a program to help cope with caregiving, alleviate related stress, and enhance quality of life for caregivers, with funding from the National Institute on Aging. This home-based program includes a free DVD, printed materials, and resource website. In addition, after completing the program, participants will have free access to final online resources for 1 year. There are no face-to-face meetings, and participants can live anywhere in the United States.

In 1906, Dr. Alois Alzheimer first described the disease that later took his name. Today, 100 years later, 24 million people worldwide suffer from Alzheimer's disease or other dementias. The term 'dementia' is clinical and is used to describe brain disorders that cause decline in mental functions, memory first and then speech, judging and overall behavior. Alzheimer's disease is by far the most common form of dementia, followed by vascular dementia, dementia with Lewy, the frontotemporal dementias etc. In Greece there are 141,000 patients with dementia. With increasing life expectancy, the figures are expected to increase dramatically in the future. Alzheimer's disease is the most common form of dementia, as well as 50-60% of patients with dementia suffer from this disease. The second most common type of dementia is vascular, ie that associated with cerebrovascular disease and is the 15-30% of all dementia cases and is most common between the ages of 60-70 years and is more common in men than women. It is estimated that 5% to 8% of people over 65 suffer from dementia, while in industrialized countries ranges at the following levels :15-25% over 85 and 32% over 90 years. Dementia is characterized by a slow onset and progressive course. The syndrome includes disorders in general intelligence, learning and memory, problem solving, perception, judgment, executive function, language and synergy of movement, but without impairment of consciousness. Alzheimer's disease is a neurodegenerative disorder with distinct clinical and histopathological features, although with variations from person to person. In its early stages it is sometimes difficult to diagnose cognitive impairment from normal aging of the brain. With the passage of time, the continuous decline in recent memory, fluency, ability for spatial orientation ultimately restricts the autonomy regarding basic activities of daily life such as managing finances. The anxiety and depression complicate diagnosis in early stages, but gradually decline with loss of sensitivity. Intermediate stages of the disease require increasingly supervision in daily self-care activities, such as personal hygiene and clothing. In the advanced stages are usually essential nursing care in institutional context. The severity of symptoms of the disease varies and is determined by premorbid factors such as education, gender, cultural background. Epidemiological studies have shown as protective factors against the onset of dementia, higher education, taking estrogen and anti-inflammatory drugs. On the other hand, age, family history of dementia, head injury, hypertension and Down syndrome are risk factors for developing the disease. Finally, some genetic factors appear to be protective, and other pressures to the disease.

Alzheimer's disease (AD) is a major public health problem due to its socio-economic weight. An early diagnosis of AD is urgently needed as it would constitute a determinant breakthrough from a social, financial and research standpoints. Therefore, the investigators need predictive markers of AD, and neuroimaging is a particularly promising tool, especially when using complementary neuroimaging techniques and a longitudinal design, allowing to assess the relationships between the different biomarkers of the disease, their dynamic and their chronology.

One of the interests of the Alzheimer Plan 2008-2010 is to provide increase support to helping families. It's also of major to involve the patient in the most active treatment possible, encouraging social inter relationship as well as cognitive and behavioural stimulation activities. In the frame of non drug related approaches to Alzheimer disease (AD), several research projects and actions have already been conducted, but no specific study concerning the efficiency of different types of respite care structures have been conducted so far in France. The present project concerns the thematic of the frame "Development and diversification of respite care structures". A platform is defined in the Alzheimer Plan as a "diversified range of despite structures according to patients' needs and informal caregivers' expectations" providing several objectives: Two objectives targeting the informal caregivers: offer spare time or tutored inform, support and accompany Two objectives targeting the patients: encourage maintain of the patient social life and relationships and work together towards his/her psychological and emotional well-being contribute to improve functional cognitive and sensory capacities The study COMPARSE suggests to compare for the patient - informal caregiver couple, the impact of three different groups of patient care on health profit; resit platform (P), the day care group (D), the control group without access to a respite structure (C).
