Active clinical trials for "Dementia, Vascular"

Cognitive and emotional symptoms are often seen in the acute phase of a stroke. The prevalence of such symptoms later and the mechanisms explaining the symptoms are not fully known. The causes of poststroke dementia are likely to be multifactorial (Cerebrovascular Diseases 2006). The investigators want to include all patients with first ever stroke without significant cognitive decline prior to the stroke (IQCODE cut-off 3,7) and follow them up for one year. At baseline we will make stroke classifications, measure neurological deficits according to NIHSS, evaluate cognitive and emotional function and make registrations of vascular risk factors, including precerebral color duplex scan with measurement of IMT in CCA. The investigators will then randomize the patients into multifactorial vascular-risk-factor-intervention in the hospital or care as usual in the primary health care. 8-12 months after stroke onset, survivors will undergo new examinations to evaluate neurological, cognitive and emotional functions, as well as MRI and SPECT.

Could Tadalafil improve blood flow in deep brain tissue and potentially improve cognitive function in patients with cerebral small vessel disease

The primary objective of this study is to evaluate the efficacy of BAC patients with Alzheimer's disease or vascular dementia.The secondary objective of this study is to evaluate the safety of BAC patients with Alzheimer's disease or vascular dementia.

Phase III randomized controlled trial designed to test the effects of a 3-year intervention of the MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) on cognitive decline and brain neurodegeneration among 600 individuals 65+ years without cognitive impairment who are overweight and have suboptimal diets.

The study is designed to determine the diagnostic efficacy of the visual assessment of SPECT scans in differentiating between probable dementia with Lewy Bodies (DLB) and non-DLB dementia subjects determined by the clinical diagnosis of an independent expert consensus panel used as the standard of truth.

This observational study will examine the association of chronic traumatic cerebrovascular injury and cardiovascular risk factors with TBI-related cognitive impairment and vascular dementia. Cerebrovascular, inflammatory, and neurodegenerative blood biomarkers as well as clinical and neuroimaging data

The physio-pathology of Alzheimer's disease (AD) remains unknown and there is no cure. Thus, the search for objective markers of preclinical first signs of cognitive impairment, is currently a major public health issue. Early detection of the disease is a major challenge to hope to slow or even stop the neurodegenerative process before the stage of dementia. In AD the investigators observe: A reduction in the volume of brain hippocampi associated with an alteration of the diffusion of water molecules in the white matter. A structural brain degeneration coupled with a decrease in cerebral glucose metabolism. Recent publications show that cerebrospinal fluid (CSF)flow is also altered, probably due to dysfunction of the choroid plexus. Hence the potential interest to study is, in addition to conventional imaging, the imaging of CSF dynamics and choroid plexus metabolism. In that aim,the investigators use two imaging modalities: Magnetic resonance imaging (MRI) is used to assess blood and CSF flow in the brain Positron emission tomography (PET) is used to assess glucose metabolism in grey/white matter and also in choroid plexus. The investigators expect that, because of choroid plexus atrophy in AD, CSF flow would be altered as well as glucose metabolism dynamic in choroid plexus.

The Healthy Patterns Study intervention is a home-based activity intervention designed to improve symptoms of circadian rhythm disorders (CRD) and quality of life (QOL) in home-dwelling persons with dementia. We will use a randomized two-group parallel design of 200 people with dementia and their caregivers assigned to intervention or attention control groups.

This is a randomized clinical trial evaluating the benefits of a program that supports model care for persons with dementia and their family caregivers. Subjects were recruited from California, Nebraska and Iowa. Subjects determined to be eligible were consented and randomized into one of two groups. Two thirds of patients were enrolled into Navigated Care that provided them with assistance in meeting important benchmarks in their care, for example completion of legal and financial planning and strategies for minimizing caregiver burden. One third of patients were enrolled to a control group, entitled Survey of Care. Outcomes include quality of life, health care utilization, caregiver burden, satisfaction with care, caregiver depression, and caregiver self-efficacy.

This international study evaluates the impact of home-based caregiver-delivered music and reading interventions for people with dementia. The project aims to address the need for improved informal dementia care by training family caregivers to utilise a music or reading intervention with the person they are caring for. The interventions aim to decrease behavioural and psychological symptoms of dementia as well as improve quality of life and well being of both people living with dementia and their caregivers. Participants will be allocated into a music intervention group, a reading intervention group or standard care group. In addition, the researchers will seek to determine the cost-effectiveness of using the music intervention.
