Filter by:Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common form of hereditary cerebral small vessel disease, with no proven disease-modifying treatments. Adrenomedullin, a vasoactive peptide, has angiogenic, vasodilation, anti-inflammatory, and anti-oxidative properties and could have triple sites of action on components of the neuro-glial-vascular unit consisting of vessels, microglia and oligodendrocytes or, more specifically, on the white matter oligovascular unit. The aim of the AMCAD trial is to assess the safety and efficacy of Adrenomedullin in CADASIL patients.
These caregivers are a vulnerable group due to their physical isolation and well-documented rural disparities in health care access and quality. Many rural dementia caregivers experience serious health consequences due to caregiving responsibilities that can limit their ability to maintain their caregiving role. Thus, there is a pressing need for effective, scalable, and accessible programs to support rural dementia caregivers. Online programs offer a convenient and readily translatable option for program delivery because they can be accessed by caregivers in the home and at the convenience of the user. Building Better Caregivers is an online 6-week, interactive, small-group self-management, social support, and skills-building workshop developed for caregivers of individuals with Alzheimer's disease or related dementia. The investigators will conduct a hybrid effectiveness-implementation randomized controlled trial that will enroll and randomize 640 rural dementia caregivers into two groups: the intervention (workshop) group and the attention control group. Caregivers will be recruited throughout the United States. Primary outcomes will be caregiver stress and depression symptoms. The investigators hypothesize that stress scores and depression symptoms will be significantly improved at 12 months in the intervention group versus control group. The investigators will also identify key strengths (facilitators) and weaknesses (barriers) of workshop implementation. The investigators will use the RE-AIM implementation framework and a mixed methods approach to identify implementation characteristics pertinent to both caregivers and rural community organizations. If the Building Better Caregivers workshop is proven to be effective, this research has the potential to open new research horizons, particularly on how to reach and effectively support isolated dementia caregivers in rural areas with an intervention that is scalable, even in low-resourced settings. If the workshop can achieve its goals with rural dementia caregivers, some of those most isolated, it would also be expected to be scalable in other low-resourced settings (e.g., in urban or suburban environments).
Cerebral autosomal dominant arteriopathy with subcortical infarct (CADASIL) is a lethal disease caused by a gene mutation that affects arteries in the brain. Symptoms include migraines, strokes, memory loss, and dementia. There are no treatments. Researchers want to study people who have CADASIL to learn more about it. Objectives: To learn more about CADASIL by studying people who have it. Eligibility: People ages 18-100 who were diagnosed with CADASIL in the past 5 years and can make their own decisions Design: Participants will be screened in another NIH protocol. Participants will have 3 visits over 2 years. These may include: - Physical exam - Thinking and concentration tests - Blood tests - Skin biopsy: A small skin punch is removed from the arm or leg - Eye exam and eye imaging tests - Fluorescein angiogram: A catheter is placed in an arm vein. Dye is given through the catheter and travels to the eyes. - EndoPAT: A small clamp on the fingertip measures blood volume. - Cardio-ankle vascular index (CAVI): Artery stiffness is tested with blood pressure cuffs on the arms and legs. Soft electrodes on the skin measure heart signals. - Brain MRI or MRA: They lie on a table that slides in and out of a tube that takes pictures. They may get a contrast agent in their vein. It brightens the brain so researchers can see where blood flows. - CT scan of the heart: They lie on a table that slides in and out of a machine that takes pictures. - They get contrast dye injected through a catheter. They may get a medicine that makes their blood vessels bigger or slows their heart rate.
The aim of this study is to investigate using fMRI methods, EEG and dedicated mathematical models, the potential alterations of neurovascular coupling in CADASIL.
The purpose of this study is to delineate early neurological features and their progression in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) in order to facilitate early diagnosis, prevent erroneous diagnosis and mistreatment and improve physician education about this relatively common yet under-recognized dementing disorder. Patients with CADASIL suffer from a variant from migraine that differs from wild type migraine in terms of its severity, progressive nature and underlying pathophysiology. Recurrent stereotypic acute confusional state associated with the headache episodes in patients with CADASIL is a distinctive phenomenon, which if recognized will lead to an earlier and accurate diagnosis of this condition. Specific Aims: - Characterize the nature, frequency and severity of migraine in patients with CADASIL. - Delineate the phenomenon of acute confusional migraine as a distinct subgroup of migraine and establish its prevalence in patients with CADASIL. - Determine the latency between the onset of neurological symptoms including migraine, and diagnosis of CADASIL and the prevalence of misdiagnosis.
