Background: Cerebral small vessel diseases (SVDs) are a major cause of stroke & dementia.
Yet, specific treatment strategies are lacking in part because of a limited understanding of the underlying disease processes.
There is therefore an urgent need to study SVDs at their core, the small vessels themselves.
Objective: This paper presents the rationale & design of the ZOOM@SVDs study, which aims to establish measures of cerebral small vessel dysfunction on 7T MRI as novel disease markers of SVDs.
Methods: ZOOM@SVDs is a prospective observational cohort study with two years follow-up.
ZOOM@SVDs recruits participants with Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts & Leukoencephalopathy (CADASIL, N = 20), sporadic SVDs (N = 60), & healthy controls (N = 40).
Participants undergo 7T brain MRI to assess different aspects of small vessel function including small vessel reactivity, cerebral perforating artery flow, & pulsatility.
Extensive work-up at baseline & follow-up further includes clinical & neuropsychological assessment as well as 3T brain MRI to assess conventional SVD imaging markers.
Measures of small vessel dysfunction are compared between patients & controls, & related to the severity of clinical & conventional MRI manifestations of SVDs.
Discussion: ZOOM@SVDs will deliver novel markers of cerebral small vessel function in patients with monogenic & sporadic forms of SVDs, & establish their relation with disease burden & progression.
These small vessel markers can support etiological studies in SVDs & may serve as surrogate outcome measures in future clinical trials to show target engagement of drugs directed at the small vessels.
