Filter by:Dementia with Lewy Bodies (DLB) is an alphasynucleinopathy and the second most common form of dementia in the elderly. DLB shares striking neuropathological and clinical similarities with both Parkinson's disease (PD) and Alzheimer's disease (AD). Nilotinib (Tasigna®, AMN107, Novartis, Switzerland) is approved by the FDA and is well tolerated for CML treatment at oral doses of 600-800mg daily. The Investigators propose to perform a phase II randomized, double blinded, placebo controlled study to evaluate the impact of Nilotinib in patients with DLB.
This study evaluates the safety and tolerability of treatment with K0706 in Dementia with Lewy Bodies (DLB). The hypothesis is that K0706 will be safe and tolerable and that this drug will alter CSF and plasma biomarkers in DLB. Clinical assessments of cognitive, behavioral and motor functioning will also be evaluated. A total of 45 participants will be randomized 1:1:1 into 3 groups (n=15/per group) to be treated with sachet of 192 mg powder of K0706 ( equivalent to 96 mg capsule of K0706) or sachet of 384 mg powder of K0706 (equivalent to 192 capsule of K0706) or sachet of matching placebo ( equivalent to a capsule of placebo) for 12 weeks, followed by 4-week wash-out period.
This home-based study is a randomized (1:1) placebo-controlled trial of a single infusion of zoledronic acid-5 mg (ZA) for the prevention of fractures in men and women aged 60 years and older with Parkinson's disease and parkinsonism with at least 2 years of follow-up. A total of 3500 participants will be enrolled and randomized in the United States. Participants, follow-up outcome assessors, and study investigators will be blinded to assigned study treatment. This trial is funded by the National Institute of Aging.
Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive disorders should be carry out. The methods of early prevention, early diagnosis and early treatment the cognitive disorders in elderly should be found to reduce the burden of the social and economic issue due to dementia. At present, the international corresponding guidelines have taken gene and brain imaging biomarkers as important indicators of dementia pathogenesis research, accurate diagnosis and targeted intervention. Based on the above understanding, the study carry out the population cohort study based on accurate diagnosis and construct the high standard information and sample bank. The study will establish the standard and quality system of geriatric cognitive disorders cohort study (unified standards and norms). The study will integrate the standard biological samples stratified acquisition function module (homogeneity and precision) of elderly cognitive disorders, and complete the construction of biological samples bank and clinical diagnosis and treatment information database. The study will apply and develop brain structural and pathological imaging technology to support precision diagnosis of senile cognitive disorders. The study will evaluate whether peripheral nerve degeneration can predict central nervous system degeneration based on the large cohort of elderly study. In addition, The study will make an effective supplement the sample bank construction of Shanghai Mental Health Center.
The goal of this study is to characterize biophysiolgoical signals as a comprehensive profile of the nervous systems in order to understand interactions between the brain and body, while an individual performs naturalistic behaviors (ex. walking, pointing) and while breathing at a slow controlled pace. The investigators aim to study these interactions among a variety of populations, from healthy individuals to those with disorders such as Autism Spectrum Disorder(s), including those who may also have an ADHD (Attention-deficit/hyperactivity disorder) diagnosis, Asperger's Syndrome, Alzheimer's Disease, and/or Fragile X syndrome
We are trying to identify factors associated with improved quality of life and fewer PD symptoms. We are attempting to identify practices, beliefs, and therapies used by individuals who report excellent quality of life, few PD symptoms, and reduced rates of progression. After agreeing to participate, we will ask participants to fill our questionnaires about their experience with PD, their health in general, along with their food intake every six months for five years.
Synucleinopathies are a group of rare diseases associated with worsening neurological deficits and the abnormal accumulation of the protein α-synuclein in the nervous system. Onset is usually in late adulthood at age 50 or older. Usually, synucleinopathies present clinically with slowness of movement, coordination difficulties or mild cognitive impairment. Development of these features indicates that abnormal alpha-synuclein deposits have destroyed key areas of the brain involved in the control of movement or cognition. Patients with synucleinopathies and signs of CNS-deficits are frequently diagnosed with Parkinson disease (PD), dementia with Lewy bodies (DLB) or multiple system atrophy (MSA). However, accumulation of alpha-synuclein and death of nerve cells can also begin outside the brain in the autonomic nerves. In such cases, syncucleinopathies present first with symptoms of autonomic impairment (unexplained constipation, urinary difficulties, and sexual dysfunction). In rare cases, hypotension on standing (a disorder known as orthostatic hypotension) may be the only clinical finding. This "pre-motor" autonomic stage suggests that the disease process may not yet have spread to the brain. After a variable period of time, but usually within 5-years, most patients with abnormally low blood pressure on standing develop cognitive or motor abnormalities. This stepwise evolution indicates that the disease spreads from the body to the brain. Another indication of this spread is that acting out dreams (i.e., REM sleep behavior disorder, RBD) a problem that occurs when the lower part of the brain is affected, may also be the first noticeable sign of Parkinson disease. The purpose of this study is to document the clinical features and biological markers of patients with synucleinopathies and better understand how these disorders evolve over time. The study will involve following patients diagnosed with a synucleinopathy (PD/DLB and MSA) and those believed to be in the "pre-motor" stage (with isolated autonomic impairment and/or RBD). Through a careful series of follow-up visits to participating Centers, we will focus on finding biological clues that predict which patients will develop motor/cognitive problems and which ones have the resilience to keep the disease at bay preventing spread to the brain. We will also define the natural history of MSA - the most aggressive of the synucleinopathies.
