What this trial studies

This project aims to create an Australian cohort of patients diagnosed with Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). The study will utilize clinical examinations, questionnaires, neuropsychological evaluations, brain MRI, blood sample analysis, and retinal imaging to characterize the clinical profile and progression of CADASIL. It is a multi-centre observational study conducted across six sites in New South Wales, Victoria, and Queensland, involving a multidisciplinary team dedicated to enhancing the understanding of this condition.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a confirmed or suspected diagnosis of CADASIL or first-degree relatives of affected individuals.

Not a fit: Patients without a diagnosis of CADASIL or significant cognitive impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the clinical features and progression of CADASIL, potentially leading to improved management strategies for patients.

How similar studies have performed: Other studies have successfully established cohorts for CADASIL, but this specific Australian cohort is a novel initiative aimed at contributing to global understanding.
