Filter by:The investigators wish to investigate the efficacy of targeted repetitive transcranial magnetic stimulation (rTMS) on expressive language in patients with Alzheimer's disease (AD). In rTMS, magnetic pulses are used to noninvasively stimulate focal areas of cortex of about a square centimeter in area. rTMS has been approved in the United States for the diagnosis of peripheral nerve conditions. Depending on the frequency of stimulation, rTMS can preferentially stimulate or inhibit cortical areas. In stroke rehabilitation, for example, inhibition of the contralateral, uninvolved hemisphere by low frequency rTMS has improved movement of the affected limbs because of less aberrant inhibition of the affected hemisphere by the healthy hemisphere. The effects of rTMS has also been investigated and found to be useful in treating refractory depression and depression in Parkinson's disease. In addition, rTMS has improved naming in patients with Alzheimer's disease and has improved cognitive abilities and memory in non-demented older adults. Two studies found that rTMS improved aphasia in patients with stroke. While these studies are small, a review of the literature suggests that there may be a beneficial role for rTMS in patients with chronic neurological conditions. In addition, rTMS appears to be well tolerated, with transient headaches being the most common side effect. In this small open label study, the investigators wish to investigate the usefulness of bilateral stimulation of the brain region termed the dorsolateral prefrontal cortex (DLPFC) in patients with AD who have naming and language deficits.
The purpose of this study is to evaluate the combination of galantamine with nimodipine in patients with mixed dementia on cognition and quality of life.
The purpose of this research study is to compare the effectiveness of Zolpidem CR to that of placebo in improving sleep efficiency in people with dementia admitted to the hospital because of their symptoms. You can participate in this study if you have dementia of the Alzheimer's type or vascular dementia. This study involves placebo; a placebo is a tablet that looks exactly like Zolpidem CR, the study drug, but contains no active study drug. We will use placebos to see if the study results are due to the study drug or due to other reasons. Zolpidem CR is also called Ambien CR and is widely available by prescription. Zolpidem CR is approved by the U.S. Food and Drug Administration (FDA) for the short-term treatment of insomnia (trouble falling or staying asleep).
The workshop is a 6-week online workshop for caregivers of people with traumatic brain injury, post traumatic stress disorder, or dementia. It is being conducted jointly by the Stanford Patient Education Research Center and the VA Greater Los Angeles Healthcare System and is supported by a grant from the Department of Veterans Affairs, Patient Care Services, Office of Care Management and Social Work. The goal of the study is to determine whether an online caregiver education and support workshop can have lasting beneficial effects in helping caregivers improve their self-management of health skills, stress, and improve their caregiving abilities.
The purpose of this study is to evaluate change of cerebral glucose metabolism by donepezil therapy and to associate change of glucose metabolism and symptoms.
The overall purpose of this research is to determine if there is a relationship between your symptoms of Dementia of the Alzheimers type and changes in the size and shape of certain brain structures during combined Donepezil (Aricept®) and Memantine (Namenda®) treatment.
Apathy usually refers to a set of behavioural, emotional and cognitive features as a reduced interest and participation in main activities of daily life, a lack of initiative, a trend toward an early withdrawal from started activities, an indifference and a flattening of affect. We have validated a new specific scale (Lille Apathy Rating Scale, LARS) in order to detect and quantify apathy in Parkinson's disease (PD). Apathy was shown to be frequent in PD with a prevalence of 32%. It has suggested that the medial frontal and limbic cholinergic deficits may underlie apathy in neurodegenerative disorders like Alzheimer's disease (AD). Such a hypothesis is supported by recent evidence indicating the beneficial effects of cholinesterase inhibitors on neuropsychiatric symptoms, mainly apathy, in AD patients. As the efficacy of rivastigmine on cognition has also been shown in PD, we aimed to assess with a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial, the efficacy and acceptability of a 6 months treatment with rivastigmine on apathy in 60 patients with PD without dementia. The primary end point will be the LARS score and the secondary end points will be the cognitive, behavioural and motor symptoms of PD. Two add-on studies will be proposed: first the measure of choline and glutamate peaks on Magnetic Resonance Spectrometry focused on the structures implicated in apathy in order to give insights in the physiopathological mechanisms of the treatment. Secondly, the recording of the REM sleep behavior disorders in relation with the cholinergic part of the pedunculopontine nucleus. Regarding that apathy could be one of the first steps toward PD dementia, treating very early could have substantial implications on the patients and their caregiver.
The LifeZig Project is a research study of a new reminiscence activity for individuals with Alzheimer's Disease (AD) and other types of dementia, based on the LifeZig system, with personalized video channels containing old photographs and music on television. The goal of the LifeZig study is to enhance the quality of life for dementia patients and their families/caregivers, decrease the burden of care, and contribute to positive interaction between dementia patients and families/caregivers.
The purpose of this study is to conduct a cross-sectional survey of primary care patients to better understand their perceptions of the risks and benefits of a screen and subsequent diagnostic confirmation of dementia.
This is a prospective, observational study of the cohort of older post-menopausal participants in the WHI Memory Study, a sub-cohort of participants in the WHI Hormone Trials. Annual cognitive assessments and ascertainment of cognitive impairment enable the continued monitoring of long-term effects of randomization to HT on cognition and identification of predictors of cognitive vulnerability and resilience in older women.
