Filter by:The purpose of this research study is to investigate the effect of a light treatment on sleep, memory and brain function. In people with mild cognitive impairment (MCI) and Alzheimer's disease, sleep-wake disturbance is evident in up to 60% of patients. This can be caused by disruption of circadian rhythms and may affect our health and well-being. Circadian rhythms are the natural cycle of physical, mental, and behavior changes that the body goes through in a 24-hour cycle. Circadian rhythms are mostly affected by light and darkness and are controlled by a small area in the middle of the brain. They can affect sleep, body temperature, hormones, appetite, and other body functions. The circadian system plays an important role in the body and can affect sleep and brain function. The results of the research would help develop light-delivery methods to improve sleep and memory in patients with mild cognitive impairment (MCI) and Alzheimer's disease who typically spend a significant amount of time indoors.
This study is being done to learn about inflammation and amyloid in Alzheimer's disease. A type of brain scan called a PET scan is used measure 1) inflammation and 2) abnormal accumulation of a the amount of a certain protein fragment called beta-amyloid (plaques) in the brain. These are thought to be involved in Alzheimer's disease. The investigators will also perform brain MRI and do tests to measure the participants' memory and thinking.
In this explorative longitudinal study 50 patients with Alzheimer's disease (AD) and 50 age-matched control subjects will be recruited for their 2 years follow-ups and undergo extensive cognitive testing and quantitative 3 Tesla magnetic resonance imaging (MRI). Regional differences of susceptibility and R2* relaxation rates in deep gray matter and the neocortex will be evaluated in AD patients and controls and related to the patients´ cognitive status at baseline.
Symptoms of agitation include abuse or aggressive behaviour toward self or others, appropriate behaviour performed with inappropriate frequency, or behaviours that are inappropriate according to social standards. In the later stages of dementia agitation can contribute significantly to patient distress and caregiver stress, and has been associated with poor quality of life. Previous research studies have shown some evidence that personalized music played in daily care situations reduces agitation. The purpose of this study is to evaluate the effects of personalized music therapy via headphones on agitation during hygiene care (grooming). This study will involve 60 in-patients of the Geriatric Psychiatry ward of Toronto Rehabilitation Institute. The study would take place over the span of 2 weeks and would involve listening to personalized and either non-personalized or no music during daily hygiene care (grooming). Enrolment is completely voluntary and all personal data obtained will remain confidential.
The purpose of this study is to determine whether the use of computerized systems in 2 common non pharmacological therapies (cognitive training and reminiscence therapy) will improve the cognitive function of patients with mild to moderate Alzheimer's disease (AD), or at least delay its deterioration. In addition, the investigators hypothesize that using the computerized systems will result in improved well-being of the patients and their main caregivers / family members, and in improved patient-caregiver and patient-family relations.
This follow-up study is designed to obtain longitudinal clinical and MEG scan data to gain information on Alzheimer's disease (AD) progression, the stability of healthy control (HC) MEG scan data, to enrich the Orasi database of AD and HC subjects, and is intended to extend the capabilities of the Synchronous Neural Interaction® (SNI) test, which is under development by the sponsor, Orasi Medical. The current study is intended to extend the database of AD and HC MEG scans and will include patients who previously enrolled and completed Orasi Protocol ADG 08-01. This study will include MEG scans on up to approximately 50 AD subjects and 70 HC subjects. Additionally, AD subjects will complete 3 standard functional tests while HC subjects will complete 2 standard functional tests. ApoE genotyping also will be determined for all subjects. The results generated in this study will be used to improve the accuracy of the SNI test for diagnosing and tracking the progression of AD.
This study will recruit a total of 150 evaluable subjects (30 cognitively normal volunteers, and 60 MCI(Mild cognitive impairment), and 60 AD(Alzheimer's disease), respectively) Each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject grouping. Safety measurement will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events. This study is expected to be completed in a period of 3 years.
This is a prospective, open label, non-therapeutic, diagnostic imaging study. The purpose of this study is to utilize Pittsburgh Compound B positron emission imaging (PiB PET) to ascertain the relationship between change in amyloid burden over time, and concurrent change in clinical status.
The Wisconsin Brain Donor Program (WBDP) stores brain and other tissues/samples (e.g. blood and CSF) from deceased individuals who have participated in longitudinal research studies, as well as other select participants. These individuals have donated their tissues in order to aid scientific research. Through the collection of central and peripheral nervous tissues as well as (in select cases) skeletal muscle tissue, the WBDP strives to advance the knowledge of diseases of memory disorders, such as Alzheimer's Disease. Brain donations are needed from healthy individuals, as well as those affected by diseases of the nervous system.
